Executive Summary
Demand-Side Management 2021 Annual Report Page 1
EXECUTIVE SUMMARY
Idaho Power, through its energy efficiency programs, its customer education programs, and its
focus on the customer experience, fully supports energy efficiency and demand response and
encourages its customers to use energy wisely.
In 2021, Idaho Power achieved 143,971 megawatt-hours (MWh) or 16.4 average megawatts
(aMW) of incremental energy efficiency savings, including Northwest Energy Efficiency Alliance
(NEEA) estimated energy savings, which exceeded the economic technical achievable potential
included in the 2021 Integrated Resource Plan (IRP) of 135,018 MWh or 15.4 aMW. The 2021
savings represent enough energy to power approximately 12,600 average homes in Idaho
Power’s service area for one year.
However, it was a challenging year due to residual impacts of COVID-19, the resulting supply
chain issues, higher labor and material costs, and the maturity of the residential lighting
market. The C&I Custom Projects option, which provides approximately half of the portfolio
savings, returned savings comparable to 2017 and 2018 as opposed to the record setting years
of 2019 and 2020. Consequently, the 2021 savings of 143,971 megawatt-hours (MWh),
including the estimated savings from the NEEA, decreased by 54,461 MWh compared to the
2020 savings of 198,433 MWh—a 27% year-over-year decrease. The savings from Idaho
Power’s energy efficiency programs alone, excluding NEEA savings, was 126,102 MWh in 2021
and 180,818 MWh in 2020—a 30% year-over-year decrease.
In 2021, the company’s energy efficiency portfolio was cost-effective from both the total
resource cost (TRC) test and the utility cost test (UCT) perspectives with ratios of 2.17 and 2.18,
respectively. The portfolio was also cost-effective from the participant cost test (PCT) ratio,
which was 2.73.
Energy efficiency and demand response are important aspects of Idaho Power’s resources to
meet system energy needs and are reviewed with each IRP. Idaho Power successfully operated
all three of its demand response programs in 2021. The total demand response capacity from
the company’s programs was calculated to be approximately 384 megawatts (MW) with an
actual load reduction of 312.8 MW.
Total expenditures from all funding sources of demand-side management (DSM) activities were
$38.4 million in 2021—$27.9 million from the Idaho Rider, $8.7 million from Idaho Power base
rates, and $1.7 million from the Oregon Rider. DSM program funding comes from the Idaho and
Oregon Riders, Idaho Power base rates, and the annual power cost adjustment (PCA).
In addition to the education customers get through participation in specific incentive programs
for energy efficiency, Idaho Power educates customers on energy efficiency in many other
ways. One of these methods is to produce an Energy Efficiency Guide with information on
Executive Summary
Page 2 Demand-Side Management 2021 Annual Report
energy efficiency equipment and ways to use energy wisely. The 2021 guide was distributed
in June, primarily as an insert in 25 local newspapers. In 2021, despite the pandemic
challenges, Idaho Power’s education and outreach energy advisors (EOEA) delivered nearly
250 presentations with energy-savings messages to audiences of all ages.

Figure 1. Example graphic from the 2021 Energy Efficiency Guide
In 2021, the Integrated Design Lab (IDL) scheduled 20 technical training lunches conducted
virtually due to COVID-19 restrictions. Fourteen sessions were coordinated directly with
architecture and engineering firms and organizations, and six were available to the public.
A total of 258 architects, engineers, designers, project managers, and others attended. The IDL
also maintains an Energy Resource Library (ERL) with tools for measuring and monitoring
energy use and provides training on how to use them. The library includes over 900 individual
pieces of equipment; 10 new tools were added in 2021.
Idaho Power continued to provide training to its commercial and industrial customers in 2021,
delivering the equivalent of six full days of technical training to over 200 individuals.
Idaho Power provided three virtual and three in-person irrigation workshops promoting
irrigation system efficiency and participated in one vendor-hosted workshop promoting the
Irrigation Efficiency Rewards program. The company normally exhibits and participates in
four agricultural trade shows, but due to COVID-19 restrictions, the shows were cancelled.
The company sponsors significant customer educational outreach and awareness activities,
promotes codes and standards, and focuses marketing efforts on saving energy—none of which
are quantified or claimed as part of Idaho Power’s annual DSM savings, but are likely to result in
energy savings that accrue to Idaho Power’s electrical system over time.
This Demand-Side Management 2021 Annual Report provides a review of the company’s DSM
activities and finances throughout 2021, outlines Idaho Power’s plans for future DSM activities

and satisfies the reporting requirements set out in Idaho Public Utilities Commission’s (IPUC)
Order Nos. 29026 and 29419. Idaho Power will provide a copy of the report to the Public Utility
Commission of Oregon (OPUC) under Oregon Docket UM 1710.

INTRODUCTION
Idaho Power has been locally operated since 1916 and serves more than 600,000 customers
throughout a 24,000-square-mile area in southern Idaho and eastern Oregon. The company
achieves energy and demand savings objectives in both its Idaho and Oregon service areas
through the careful management of current programs, the offering of new cost-effective
programs, and through customer outreach and education; collectively, the implementation,
operation, tracking, and evaluation of these programs and offerings is called demand-side
management (DSM).

Figure 2. Idaho Power service area map
Idaho Power’s main objectives for DSM programs are to achieve prudent cost-effective energy
efficiency savings and to provide useful and cost-effective demand response (DR) programs as
determined by the Integrated Resource Plan (IRP) planning process. Idaho Power strives to
offer customers valuable programs and information to help them wisely manage their energy
usage. DSM programs and offerings by customer sector (residential, commercial/industrial,
and irrigation) are shown in Table 1.

Idaho Power focuses on the customer experience when providing information and programs
that ensure customers have opportunities to learn about their energy use, how to use energy
wisely, and how to participate in the programs. As necessary, Idaho Power modified DSM
activities with respect to COVID-19 to prioritize the safety of customers, contractors,
and Idaho Power staff while still balancing opportunities to maintain program performance.
Much of the customer in-home or on-location work was suspended for at least part of 2021.
The company utilized virtual meetings and leveraged technology to maintain participation.

Energy efficiency and demand response funding comes from multiple sources: Idaho Power
base rates, the Idaho and Oregon Energy Efficiency Riders (Rider), and the annual power cost
adjustment (PCA) in Idaho. Idaho incentives for the company’s demand response programs are
recovered through base rates and the annual PCA, while Oregon demand response incentives
Introduction
Page 8 Demand-Side Management 2021 Annual Report
are funded through the Oregon Rider. Total expenditures on DSM-related activities from all
funding sources were $38.4 million in 2021 (Figure 3).
Figure 3. DSM expense history by program type, 2002–2021 (millions [$])
DSM Program Performance
A summary of the energy efficiency and demand response program performance metrics is
presented in this section and in individual program sections later in this report. Appendices 1
through 4 provide additional details on the funding, expenditures, and savings at the program
and sector levels.
Energy Efficiency
Energy efficiency programs are available to all customer sectors in Idaho Power’s service area
and focus on reducing energy use by identifying homes, buildings, equipment, or components
for which an energy-efficient design, replacement, or repair can achieve energy savings.
Some energy efficiency programs include behavioral components. For example, the Residential
Energy Efficiency Education Initiative (REEEI), the seasonal contests, the School Cohort,
Water and Wastewater Cohorts, and the Home Energy Report (HER) Program primarily focus on
behavioral energy savings.
Savings from energy efficiency programs are measured on a kilowatt-hour (kWh) or
megawatt-hour (MWh) basis. Programs can supply energy savings throughout the year or at
different times, depending on the energy efficiency measure. Idaho Power shapes the
energy-savings profile based on how end use equipment uses energy to estimate energy
reduction at specific times of the day and year. The company’s energy efficiency offerings
Introduction
Demand-Side Management 2021 Annual Report Page 9
include programs in residential and commercial new construction (lost opportunity savings),
residential and commercial retrofit applications, and irrigation and industrial system
improvement or replacement. Idaho Power’s incentives are offered to its irrigation, industrial,
large-commercial, small business, government, and school customers to promote a wide range
of energy-saving projects.
Idaho Power invests significant resources to maintain and improve its energy efficiency and
demand response programs; however, due to continued impacts and extensive disruptions to
many programs from COVID-19, savings were impacted in 2021 as compared to previous years.
The 2021 total savings of 143,971 MWh, including savings from the Northwest Energy Efficiency
Alliance (NEEA), decreased by 54,461 MWh compared to the 2020 savings of 198,433 MWh—
a 27% year-over-year decrease. The 2021 savings represent enough energy to power over
12,500 average homes in Idaho Power’s service area for one year. The savings from
Idaho Power’s managed energy efficiency programs, excluding NEEA savings, were
126,102 MWh in 2021 and 180,818 MWh in 2020—a 30% year-over-year decrease (Figure 4).
Figure 4. Annual energy savings and energy efficiency program expenses, 2002–2021
(MWh and millions [$])
The 2021 savings results consisted of 21,218 MWh from the residential sector, 95,184 MWh
from the commercial/industrial sector, and 9,700 MWh from the irrigation sector. The C&I
programs contributed 75% of the direct program savings. In the residential sector,
Home Energy Reports contributed the largest savings at 75%, and Educational Distributions
contributed the second largest savings at 14%, for a combined total savings of 89%.

Demand Response
Idaho Power started its modern demand response programs in 2002 and now has a capacity of
over 10% of its all-time system peak load available to respond to a system peak load event
during the summer. The goal of demand response at Idaho Power is to minimize or delay the
need to build new supply-side peaking resources. The company estimates future capacity needs
through the IRP planning process and plans resources to mitigate predicted system deficits.
Demand response program results are measured by the amount of demand reduction in MW
achieved by the company during called events.
In summer 2021, Idaho Power utilized all or portions of the programs on 11 different days
between June 15 and August 15. The 2021 actual maximum non-coincidental load reduction
from all three programs was 312.8 MW. The total capacity for all three programs was estimated
to be approximately 384 MW at the generation level (Figure 5). The amount of capacity
available for demand response varies based on weather, time of year, and how programs are
used and managed. The actual non-coincidental load reduction (312.8 MW) is calculated using
interval meter data from participants. The maximum capacity (384 MW) is calculated using the
total enrolled MW from participants with an expected maximum realization rate for those
participants. The maximum capacity for the Irrigation Peak Rewards program is based on the
maximum reduction possible during the hours within the program season. For the Flex Peak
Program, the maximum capacity is the maximum nominated amount of load reduction. For the
A/C Cool Credit program, the capacity is calculated based on the number of active participants
multiplied by the maximum per-unit reduction ever achieved.

Introduction
Demand-Side Management 2021 Annual Report Page 11
The 2021 program season will be the final season the company operates the programs under
the terms of the Idaho Public Utilities Commission (IPUC) Order No. 32923 and Public Utility
Commission of Oregon (OPUC) Order No. 13-482, which previously established operating
parameters for the programs. As a result of Idaho Power’s analysis, while developing its
2021 IRP, the company proposed operational and incentive changes to the demand response
programs. These changes were approved by IPUC Order No. 35336 (IPC-E-21-32) and
OPUC ADV 1355. These changes will supersede the terms of the 2013 settlement agreement.

Customer Education
Idaho Power produced an Energy Efficiency Guide in 2021 and distributed it in June, primarily as
an insert in 25 local newspapers. Due to the continuing impacts resulting from COVID-19,
Idaho Power participated in only a few public-facing events; however, the company continued
its enhanced digital communication efforts to bring a variety of energy and money-saving tips
to customers. Idaho Power also distributed 1,160 copies of the 30 Simple Things You Can Do to
Save Energy booklet directly to customers. In 2021, despite the pandemic challenges,
Idaho Power’s EOEAs delivered nearly 250 presentations with energy-savings messages to
audiences of all ages.
Idaho Power supports the Integrated Design Lab (IDL), which conducted Lunch & Learn sessions
to educate architects, engineers, and other design and construction professionals about various
energy efficiency topics. In 2021, the IDL scheduled 14 virtual technical training sessions with
104 architects, engineers, designers, project managers, and other interested parties. Also,
IDL hosted six virtual Building Simulation Users Group (BSUG) sessions with 154 professionals
attending.
Introduction
Page 12 Demand-Side Management 2021 Annual Report
The IDL also maintains an Energy Resource Library (ERL) with tools for measuring and
monitoring energy use and provides training on how to use them. The ERL includes over
900 individual pieces of equipment and 10 new tools added in 2021. In 2021, the ERL home
page had 1,483 visitors.
Over the course of 12 days in 2021, Idaho Power delivered six equivalent full-time days of live
technical online training sessions at no cost to the customers. Topics included the following:
• Industrial Refrigeration
• Motors
• Variable Frequency Drives (VFD)
• Introduction to Unitary Air Conditioning
• Advanced Unitary Air Conditioning
• Harmonics
The level of participation in 2021 remained high, with 221 individuals signing up for the sessions
and 208 unique logins. Due to the virtual nature of the course, in some cases, there were
multiple attendees at a single login location.
Aside from the classes listed above, Idaho Power also partnered with Northwest Energy
Efficiency Council (NEEC) to administer a Building Operator Certification Level I Course which
began in November 2021 and continues through May 2022. Idaho Power sponsored
17 customers who signed up for the training by paying $900 of the $1,895 tuition cost.
Idaho Power provided three virtual and three in-person irrigation workshops promoting
irrigation system efficiency in 2021 and participated in one vendor-hosted workshop promoting
the Irrigation Efficiency Rewards program. The company normally exhibits and participates in
four agricultural trade shows, but the shows were cancelled due to COVID-19 restrictions.
Surveying Customer Satisfaction
Relationship surveys measure the satisfaction of several aspects of a customer’s relationship
with Idaho Power, including energy efficiency, at a very high level. As such, the surveys are not
intended to measure all aspects of the energy efficiency programs.
The 2021 survey asked two questions related specifically to satisfaction with Idaho Power’s
energy efficiency programs: 1) Have you participated in an Idaho Power energy efficiency
program? 2) Overall, how satisfied are you with the energy efficiency program? In 2021, 35% of
the survey respondents across all sectors indicated they participated in an Idaho Power energy
efficiency program, and 94% were “very” or “somewhat” satisfied with the program they
participated in.

Program Evaluation Approach
Idaho Power considers program evaluation an essential component of its DSM operational
activities. The company uses third-party contractors to conduct impact, process, and other
evaluations on a scheduled and as-required basis. In some cases, research and analyses are
conducted internally and managed by Idaho Power’s Research and Analysis team within the
Customer Relations and Energy Efficiency (CR&EE) department. Third-party contracts are
generally awarded using a competitive-bidding process managed by Idaho Power’s Corporate
Services department.
Idaho Power uses industry-standard protocols for its internal and external evaluation efforts,
including the National Action Plan for Energy Efficiency—Model Energy Efficiency Program
Impact Evaluation Guide, the California Evaluation Framework, the International Performance
Measurement and Verification Protocol (IPMVP), the Database for Energy Efficiency Resources,
and the Regional Technical Forum’s (RTF) evaluation protocols.
The company also supports regional and national studies to promote the ongoing
cost-effectiveness of programs, the validation of energy savings and demand reduction, and the
efficient management of its programs. Idaho Power considers primary and secondary research,
cost-effectiveness analyses, potential assessments, and impact and process evaluations to be
important resources in providing accurate and transparent program-savings estimates.
Idaho Power uses recommendations and findings from the evaluations and research to
continuously refine its DSM programs.
For a summary of evaluation results, recommendations, and responses of evaluations
completed in 2021, see each program section. For copies of 2021 program evaluation reports
and the evaluation schedule, see Supplement 2: Evaluation.
Cost-Effectiveness Goals
Idaho Power considers cost-effectiveness of primary importance in the design, implementation,
and tracking of the energy efficiency and demand response programs. Prior to the actual
implementation, Idaho Power performs a cost-effectiveness analysis to assess whether a
potential program design or measure will be cost-effective. Incorporated in these models are
inputs from various sources that use the most current and reliable information available.
Idaho Power strives for all programs to have benefit/cost (B/C) ratios greater than one for the
total resource cost (TRC) test, utility cost test (UCT), and participant cost test (PCT) at the
program and measure levels, where appropriate. Each cost-effectiveness test provides a
different perspective, and Idaho Power believes each test adds value when evaluating overall
Introduction
Page 14 Demand-Side Management 2021 Annual Report
program performance. In 2020, Idaho Power transitioned to using the UCT as the primary
cost-effectiveness test for energy efficiency resource planning as directed by the IPUC in
Order No. 34503. The company plans to continue to calculate the TRC and PCT because each
perspective can help inform the company and stakeholders about the effectiveness of a
particular program or measure. Additionally, programs and measures offered in Oregon must
use the TRC as the primary cost-effectiveness test as directed by the OPUC in Order No. 94-590.
There are many assumptions when calculating the cost-effectiveness of a given program or
measure. Savings can vary based on several factors, such as participation levels or the
participants’ locations. For instance, heat pumps installed in the Boise area will have lower
savings than those installed in the McCall area. If program participation and savings increase,
fixed costs, such as labor and marketing, are distributed more broadly, and the program
cost-effectiveness increases.
When an existing program or measure is not cost-effective, Idaho Power works with its Energy
Efficiency Advisory Group (EEAG) to obtain input before making its determination on
continuing, discontinuing, or modifying an offering. The company must demonstrate why a
non-cost-effective measure or program continues to be offered and communicate the steps the
company plans to take to improve cost-effectiveness. This aligns with the expectations of the
IPUC and OPUC.
As part of the public workshops on Case No. IPC-E-13-14, Idaho Power and other stakeholders
agreed on a specific method for valuing demand response. The settlement agreement, as
approved in IPUC Order No. 32923 and OPUC Order No. 13-482, defined the annual value of
operating the three demand response programs for the maximum allowable hours. This value
has been updated with each IRP reflecting changes to the assumed capital cost of the deferred
resource and the financial assumptions. As a result of the analysis completed in preparation for
the 2021 IRP, changes to this approach were approved by IPUC Order No. 35336 (IPC-E-21-32)
and OPUC ADV 1355. These changes will supersede the terms of the 2013 settlement
agreement and include a different cost-effectiveness methodology that Idaho Power will rely
on going forward.
Details on the cost-effectiveness assumptions and data are included in Supplement 1:
Cost-Effectiveness.
Energy Efficiency Advisory Group
Formed in 2002, EEAG provides input on enhancing existing DSM programs and on
implementing energy efficiency programs. Currently, EEAG consists of 12 members
representing a cross-section of Idaho Power customers from the residential, industrial,
commercial, and irrigation sectors, as well as individuals representing low-income households,
Introduction
Demand-Side Management 2021 Annual Report Page 15
environmental organizations, state agencies, city governments, public utility commissions, and
Idaho Power.
EEAG meets quarterly, and when necessary, Idaho Power facilitates additional meetings and/or
calls to address special topics. In 2021, four regular virtual EEAG meetings and one special
webinar were held. The meetings were on February 10, May 5, August 12, and November 10,
and the webinar was on March 24. EEAG meetings are generally open to the public and attract
a diverse audience. Idaho Power appreciates the input from the group and acknowledges the
commitment of time and resources the individual members give to participate in EEAG
meetings and activities.
During these meetings, Idaho Power discussed new energy efficiency program ideas and new
measure proposals, marketing methods, and specific measure details. The company provided
the status of energy efficiency expenses and Idaho and Oregon Rider funding, gave updates of
ongoing programs and projects, and supplied general information on DSM issues and other
important issues occurring in the region.
Idaho Power relies on input from EEAG to provide a customer and public-interest view of
energy efficiency and demand response. Additionally, Idaho Power regularly provides updates
on current and future cost-effectiveness of energy efficiency programs and how changes in the
IRP will impact DSM alternate costs, which Idaho Power uses in calculating cost-effectiveness.
In the meetings, Idaho Power frequently requests input and feedback from EEAG members on
programmatic changes, marketing tactics, and incentive levels. EEAG often recommends
presentation ideas for future meetings.
Throughout 2021, Idaho Power relied on input from EEAG on the following important topics.
For complete meeting notes, see Supplement 2: Evaluation.
COVID-19 Impacts
The continued effects of the COVID-19 pandemic had broad impacts on the company’s energy
efficiency efforts. Idaho Power worked diligently to seek new ways to maintain activity while
prioritizing the safety of customers, contractors, and employees. At each meeting, Idaho Power
informed EEAG of the status of each program. Much of the in-home or on-location work was
suspended most of the year, but as state safety guidelines were developed, more on-location
work resumed. The company continued its efforts from 2020 to explain program availability
and guided customers to participation opportunities.
As the pandemic continued in 2021, the company shared with EEAG how it updated marketing
material to provide energy efficiency tips for customers who may be spending more time at
home and continued to successfully market virtual training sessions resulting in high trade
ally participation.
Introduction
Page 16 Demand-Side Management 2021 Annual Report
WAQC
The company continued discussions with EEAG throughout 2021 on the WAQC program.
Weatherization managers transitioned to a new state auditing tool, and because Idaho Power
had built-in integration with the existing auditing tool for job cost calculations, the company has
been working with weatherization managers and the Community Action Partnership
Association of Idaho (CAPAI) to develop and improve a new job cost calculator. In the
November EEAG meeting, Idaho Power presented several ideas/options on how to use the
WAQC carryover funds accrued over primarily the last couple of years and solicited feedback on
those options.
Welcome Kits
In 2021, the Welcome Kits became the largest kit program, with goals of marketing energy
efficiency programs and educating customers about ways to save energy at home. Although the
program was well-received by Idaho Power customers, changes in deemed savings values
reduced the kits’ overall savings. Idaho Power discussed new savings assumptions, ways to
lower kit costs and the educational, and cross-marketing benefits with EEAG in the August and
November meetings. This collaboration yielded a new kit configuration with higher energy
savings and a decision that kits would not need to be entirely cost-effective due to the difficulty
in measuring the educational benefits.
Shade Tree Project
At the August meeting, Idaho Power brought alternatives to EEAG on possible modifications to
the Shade Tree Project. There was support for continuing in 2021 with a hybrid model for
getting trees to customers. The selected hybrid model includes an option for receiving a smaller
tree by mail or picking up a larger tree in person. The company proposed a method to space out
pick-ups—and should there be a need to cancel events, the company would have the ability to
find alternatives for the trees.
ETO Pilots
As a result of an OPUC directive (OPUC Order No. 21-184) to review all energy-efficient
measures piloted by the Energy Trust of Oregon (ETO) between 2018 and 2020, the company
reviewed these measures in detail with EEAG at the August meeting. Prior to the EEAG meeting,
Idaho Power contacted ETO staff and reviewed each measure and program to gain an
understanding of the details of each pilot. During the EEAG meeting, Idaho Power presented its
analysis of the 14 pilots, shared learnings, and discussed recommendations. This resulted in the
determination that the higher kWh savings measures are already included in Idaho Power’s
programs. A few measures, such as commercial smart thermostats, ductless heat pump (DHP)
controllers and wall heaters for multifamily applications, that Idaho Power is continuing to view
Introduction
Demand-Side Management 2021 Annual Report Page 17
data and information on to determine if they could be added to Idaho Power’s programs in
the future.
Demand Response Programs
At the May and August EEAG meetings, Idaho Power presented the analysis of DR programs
completed to date as part of the 2021 IRP. The company described how the 2021 analysis
determined a need to change the focus of Idaho Power’s demand response programs from
supplying peak needs to supplying net peak needs that happen later in the evenings as solar
energy generation drops off. The company sought input and shared its plan to seek regulatory
approvals for modifications that could be in place prior to the 2022 demand response season.
Future Plans for DSM Programs
Idaho Power will continue to pursue all prudent cost-effective energy efficiency and the
amount of demand response identified in each future IRP. The forecasted level of energy
efficiency is informed by a third-party potential study and reviewed with each IRP. Idaho Power
will be completing a potential study in 2022 for demand response that will inform potential
future demand response programs and the IRP planning process. The IRP is developed in a
public process that details Idaho Power’s strategy for economically maintaining the adequacy of
its power system into the future.
In 2019, the IPUC issued Order No. 34503 directing Idaho Power to use the UCT for energy
efficiency resource planning. In 2020, the company contracted with a third party to develop a
new energy efficiency potential study, and Idaho Power also updated its third-party
Commercial/Industrial Technical Reference Manual (TRM) to include the 2018 International
Energy Conservation Code (IECC) information.
The company continuously searches for new measures for its programs through a membership
in E Source, contacts with other utilities, participation in the NEEA Regional Emerging
Technology Advisory Committee (RETAC), and from the RTF. Idaho Power representatives also
attend national conferences and participate in webinars hosted by organizations interested in
advancing energy efficiency savings.
Idaho Power will continue to work in consultation with EEAG to expand or modify its energy
efficiency portfolio. Plans for individual programs are included under each program’s 2022
Program and Marketing Strategies section.
In 2022, Idaho Power will continue to enhance its marketing and outreach efforts as described
in the Marketing section of this report and within each program section. Idaho Power will
continue to work with NEEA on its market transformation activities during its 2020–2024
funding cycle and, as directed by the IPUC (Order No. 35270), will conduct an independent
evaluation of NEEA energy savings to review methodologies NEEA employs for claiming energy

customers.
Below is a summary highlighting activities Idaho Power is actively engaged in for 2022 and
beyond. Programs and offerings on this list are developing and may not all be implemented:
• My Account: In early 2022, the company will launch a new version of its My Account
online customer tool. As part of this upgrade, customers can view improved energy-use
insights and energy-efficiency options, including the option to set energy-savings goals
and follow steps to achieve them
• Online Marketplace: Idaho Power is actively working with a vendor to potentially
implement an online marketplace to encourage and enable residential customers to
make energy efficient purchases. The marketplace would allow Idaho Power residential
customers to explore and compare appliances and other products to determine which
would save the most energy, be the most cost-effective, and qualify for Idaho Power
energy-efficiency incentives.
• Energy Efficient Lighting: Idaho Power launched a new retail lighting buy-down program
in early 2022 to replace the Bonneville Power Administration (BPA)-sponsored program,
Simple Steps, Smart Savings™ that ended in 2020 due to overall market transformation
in residential lighting. The new program focuses on fixtures and efficient lightbulbs that
are not fully transformed in Idaho Power’s service area. Savings from this program will
begin in 2022.
• Heating & Cooling Efficiency (HCE) Program: Idaho Power plans to add air conditioning
(A/C) units and ground-source heat pump measures to the HCE program. Incentives for
the new measures should be available mid-year 2022.
• Multifamily New Construction Offering: Idaho Power is re-exploring options for a
multifamily new construction offering to determine if it could be cost-effective.
• Industrial Wastewater Cohort: Idaho Power is actively working to design a new cohort
for Industrial Wastewater facilities to focus on the technical opportunities to give
operators skills they can use immediately to save energy by means of webinars, treasure
hunts, and creating energy models. Idaho Power’s key account energy advisors are
actively gauging interest from potential customers.
• Find n’ Fix Offering: Idaho Power has implemented a Find n’ Fix offering under the
C&I Energy Efficiency Custom Projects option. The Find n’ Fix offering is a service for
commercial and industrial customers that will identify and implement potential low-cost
energy savings opportunities during an onsite visit.

2021 DSM PROGRAM ACTIVITY
DSM Funding and Expenditures
Funding for DSM programs comes from several sources. The Idaho and Oregon Rider funds are
collected directly from customers on their monthly bills. Effective Jan 1, 2021, pursuant to IPUC
Order No 34871, the 2021 Idaho Rider was 3.1% of base rate revenues. The 2021 Oregon Rider
was 4% of base rate revenues. Additionally, Idaho demand response program incentives were
funded through base rates and the annual PCA mechanism. DSM expenses not funded through
the Rider are included in Idaho Power’s ongoing operation and maintenance (O&M) costs.
Table 5 shows the total expenditures funded by the Idaho and Oregon riders and Idaho Power
base rates resulting in Idaho Power’s total DSM expenditures of $38,353,505. The non-rider
funding category includes the company’s demand response incentives in Idaho, WAQC
expenses, and O&M costs.

Marketing
Idaho Power used multi-channel marketing and public relations (PR) strategies in 2021 to
improve communication and increase energy efficiency program awareness among its
customers. The company employs a wide variety of media and marketing, including owned
media (social, website, and newsletters) and paid media (advertising and sponsorships),
which allow Idaho Power to control the content. Earned unpaid media (news coverage,
Idaho Power’s News Briefs sent to reporters, third-party publications, and television news
appearances) gives Idaho Power access to a broader audience through alternative channels that
help establish credibility and brand trust. Though the company has less control with earned
unpaid media, the value is established through the third-party endorsement.
Idaho Power’s marketing staff networks with organizations across the region and industry to
track current and future marketing trends and successes. Idaho Power continued to work with
NEEA to coordinate, collaborate, and facilitate marketing for all sectors. To build marketing
networks and learn what works in other regions, Idaho Power staff virtually attended a variety
of conferences and webinars in 2021, such as the E Source Utility Marketing Executive Council
and Forum in September.
The following describes a selection of the methods, approaches, and strategies used by
Idaho Power to engage customers regarding energy efficiency, along with their results. See the
respective sector overviews and programs sections later in this report for the company’s
marketing efforts specific to those areas.
2021 DSM Program Activity
Page 24 Demand-Side Management 2021 Annual Report
Social Media
Approximately 24% of the company’s total social media content promoted energy efficiency in
2021. Idaho Power regularly posted content encouraging energy efficiency behaviors,
program enrollment, and customer engagement on Facebook, Twitter, YouTube, and LinkedIn.
Social media content also showcased local businesses and organizations that have benefitted
from Idaho Power energy efficiency efforts. Idaho Power engaged with customers who posted
their own social media content about Idaho Power programs. Idaho Power’s Facebook and
Twitter pages hosted two customer sweepstakes giveaways, encouraging customers to enter by
leaving a comment about how they save energy in the summer or winter.
In 2021, Idaho Power social channels focused on sharing energy efficiency tips that made sense
for customers spending more time at home and working on home improvement projects.
Primarily on LinkedIn, tips were provided to help businesses customers save energy while
operating with fewer employees in the office or with reduced working hours.
Idaho Power’s Facebook followers increased 4% in 2021, from 22,800 at the end of 2020 to
23,749 at the end of 2021. Facebook remains the company’s priority channel for engaging
directly with customers and was the main platform for focusing on COVID-19 safety messages,
energy assistance for customers, crisis communications, energy efficiency tips and program
offerings, and helping customers with account-related issues through private messages.
Idaho Power uses Twitter to communicate about media items, large outages, company news,
energy efficiency, and recreation opportunities. COVID-19 messaging was also shared on the
platform in 2021. Idaho Power’s Twitter followers increased 6.6% in 2021, from 6,210 followers
to 6,620.
Idaho Power again saw a favorable increase in followers on LinkedIn with 1,506 new followers
in 2021. LinkedIn is an effective channel for engaging business and commercial customers in
energy efficiency, as well as positioning the company as a good corporate citizen, clean energy
leader, and employer of choice.
Website
Idaho Power tracked the number of page views to the main energy efficiency pages—also
known as landing pages—from external users on the company’s website. In 2021, the
company’s energy efficiency homepage received 5,822 page views, the residential landing page
received 167,805 views, and the business and irrigation landing pages received 21,816.
Idaho Power uses Google Analytics to analyze web activity. Google’s definition of page views is
the total number of pages viewed, with repeated views of a single page by one user counted as
a new view.
2021 DSM Program Activity
Demand-Side Management 2021 Annual Report Page 25
Public Relations
Idaho Power’s PR staff supported energy efficiency programs and activities through these
channels: videos telling energy efficiency success stories; Connections, a customer newsletter
distributed in monthly bills and available online; News Briefs, a weekly email of interesting news
items sent to all media in the company’s service area; pitching and participating in news stories;
energy efficiency TV segments; and public events (such as incentive check presentations).
In 2021, the February and August issues of Connections were devoted to energy efficiency.
The February issue included a variety of ideas for energy-saving tips, such as how to save
energy in the kitchen and ideas about how to invest wisely in home energy efficiency
improvements. The August edition focused on energy efficiency for businesses and schools,
including a success story about Swan Falls High School, changes to incentives for business
customers, and the Residential New Construction Program.
Summer 2021 presented a unique need for energy efficiency messaging. The historic heatwave
that descended on the western U.S. in late June stretched energy resources enough that the
company put out a voluntary call to customers to help lighten the load. Social media messaging
included tips about how to save energy during the high demand hours of 4–9 p.m., with one
post alone reaching 42,000 people. Another post showed what the company was doing to help
and encouraged other businesses to do the same. The company also amplified messaging from
customers about the energy-saving measures they were taking. Messaging was repeated on the
company’s website, including a new dedicated web page, and through the news media.
Coverage on a local Boise TV station reached nearly 900,000 people, and total coverage for the
primary week of messaging was estimated at 301 million. Paid advertising was placed on digital
and radio. The company also reached out directly to customers via text message and email.
Idaho Power produced new energy efficiency success-story videos in 2021 highlighting the
energy efficiency efforts of McCain Foods and Swan Falls High School. Combined, the videos
received 4,991 views on YouTube and an additional 1,111 views on Facebook.
Media outreach efforts resulted in a variety of earned media coverage focused on energy
efficiency. Energy efficiency topics were pitched in News Briefs throughout the year, and the
company earned media coverage in multiple markets spanning print, TV, and radio.
2022 Marketing Activities
In 2022, the Idaho Power marketing department plans to introduce new strategies to expand
the reach and visibility of the company’s energy efficiency advertisements (ads).
The marketing team will update the Residential Energy Efficiency Awareness Campaign and will
run energy efficiency messaging on digital podcasts. Seasonally relevant bill inserts and emails
will be sent quarterly featuring energy efficiency tips. Additionally, the company will continue
2021 DSM Program Activity
Page 26 Demand-Side Management 2021 Annual Report
to update collateral and displays as needed for irrigation programs and various sector trade
shows (many of which will be virtual). See the sector overview sections for more specific future
marketing plans.

Customer Satisfaction Surveys
Idaho Power does not separately survey most energy efficiency program participants each year,
primarily due to concerns about over-surveying program participants and because the
measures and specifics of most program designs do not change annually. To ensure meaningful
results, Idaho Power conducts program research every two to three years unless programs have
been changed significantly. Throughout 2021, Idaho Power administered several surveys
regarding energy efficiency programs to measure customer satisfaction. Some surveys were
administered by a third-party contractor; other surveys were administered by Idaho Power
either through traditional paper or electronic surveys or through the company’s online panel—
Empowered Community. Results of these studies are included in Supplement 2: Evaluation.
The sector-level results of the annual 2021 Burke Customer Relationship Survey are available in
the Residential, Commercial and Industrial, and Irrigation sector overview sections of this
report.
Evaluations
In 2021, Idaho Power contracted third-party evaluators to conduct program evaluations for the
A/C Cool Credit (impact evaluation), C&I Custom Projects (impact and process evaluation),
Flex Peak (impact evaluation), Heating & Cooling Efficiency (impact and process evaluation),
and Irrigation Peak Rewards (impact evaluation) programs.
In 2020, Idaho Power contracted a third-party evaluator to conduct a process evaluation on the
Home Energy Report Program. However, due to some late findings, additional analysis was
required to complete the evaluation, which was finalized in June 2021. Idaho Power also
contracted a third-party evaluator to conduct a process evaluation on the Small Business Direct
Install (SBDI) program in 2020. The start of the evaluation was delayed until the second quarter
of 2021 to allow time for additional installs to be completed after the program was suspended
in early 2020 due to the COVID-19 pandemic. The evaluation was completed in October 2021.
External program administrators also compiled program summary reports for SEEK, Home
Energy Report, and Commercial Energy-Saving Kits programs. While external impact evaluations
were conducted on all three demand response programs, the company also conducted internal
analyses for the Flex Peak and Irrigation Peak Rewards programs.
A summary of the results of these evaluations is available in the respective program sections.
An evaluation schedule and the final reports from evaluations and research completed in 2021
are provided in Supplement 2: Evaluation.

Demand Response Program
A/C Cool Credit. A program that gives residential customers a credit for allowing Idaho Power to
cycle their A/C units during high-energy demand in the summer.
Marketing
Idaho Power ran a multi-faceted advertising campaign in the spring (May and June) and fall
(October and November) to raise and maintain awareness of the company’s energy efficiency
programs for residential customers and to demonstrate that saving energy does not have to be
challenging. The campaign used radio, television, newspaper ads, digital ads, and Facebook ads
and boosted posts aimed at a variety of customer demographics across the service area. New in
2021, the company added weather-triggered billboards and two new seasonally relevant
contests: Loads of Energy Savings Summer Giveaway and Touchdown to Energy Savings Fall
Giveaway. Another new tactic included energy efficiency tips on the company’s e-bill during the
residential energy efficiency campaign.
Described below are Idaho Power’s marketing efforts to promote energy-saving tips and the
company’s energy efficiency programs, along with resulting data. Marketing tactics related to a
specific sector or program are detailed in those respective sections later in this report.
Email
Idaho Power continued its effort with email communication in 2021. The company emails only
those customers who have supplied their addresses for other business purposes (signing up for
paperless billing, for example). Energy efficiency promotional emails included heating and
cooling tips, summer and winter contest promotion, and various program promotions
(detailed information can be found in respective program sections).
Digital
During the Spring campaign, web users were exposed to 3,766,154 display ads (animated GIF
image ads embedded on a website) based on their demographics, related to online articles they
viewed, or their use of a particular mobile web page or app. Users clicked the ads 5,490 times,
resulting in a click-through rate of 0.18%. In the fall, the display ads received
3,606,449 impressions and 3,174 clicks, resulting in a click-through rate of 0.09%.
Idaho Power began using Google search ads in 2018. When people search for terms related to
energy efficiency, energy efficiency programs, and individual program measures, the company’s
ads appear and drive them to the appropriate energy efficiency web page. These ads received
769,230 impressions and 124,723 clicks throughout the year.
Owned-Digital
An ad promoting EE tips was featured on Idaho Power’s e-bill sent to customers enrolled in the
paperless billing program. A total of 178,844 e-bills featuring the ad were sent in October and
Residential Sector Overview
Page 32 Demand-Side Management 2021 Annual Report
182,592 were sent in November. The October bill generated 139,792 unique opens and the
November bill generated 133,087 unique opens.
Television
Idaho Power used network television and Hulu advertising for the spring and fall campaigns.
The company also used over-the-top (OTT) media. OTT is a type of streaming media that
delivers content to customers watching a certain online show. Most OTT providers have their
own app or website and are streamed through devices like Rokus, Apple TVs, or Amazon Fire
TVs. The network television campaigns focused on primetime and news programming that
reaches the highest percentage of the target market: adults age 25 to 64.
During the spring campaign, an ad ran 1,448 times in the Boise, Pocatello, and Twin Falls media
markets on network television. The ad reached 69% of the Boise target audience (and reached
Malheur County in Oregon), 57% of the Twin Falls target audience, and 52% of the Pocatello
target audience. The target audience saw the ad 6.5 times in Boise, 9 times in Twin Falls, and 5
times in Pocatello. Hulu spring ads delivered 717,324 impressions with a 98.2% completion
rate. OTT ads delivered 303,553 impressions with a 97.13% video completion rate. The spring
campaign also utilized Spanish network television ads. The Boise target audience saw 127 paid
spots and the Pocatello market saw 51 spots. Spanish TV ads ran during the fall campaign as
well; the Boise target audience saw 124 paid spots, and the Pocatello audience saw 34 spots.
Ad reach and frequency information are not available for Spanish stations.
During the fall campaign, the TV spot ran 1,311 times in the Boise, Pocatello, and Twin Falls
media markets. The ads reached 31.3% of the Boise target audience, 67% of the Twin Falls
target audience, and 29.1% of the Pocatello target audience. The target audience saw the ad
4.5 times in Boise, 5.4 times in Twin Falls, and 5 times in Pocatello. Hulu ads received 652,831
completions. OTT ads delivered 304,898 impressions with a 98% video completion rate.
Idaho Power also sponsored commercials on Idaho Public Television in the Boise and Pocatello
markets that ran a total of 72 times.
The energy efficiency television segments that aired in Boise on network news continued to
receive positive feedback in 2021 but were limited due to COVID-19 restricting guests at
television stations and changing programing priorities. In 2021, the television station began
charging for each segment. Idaho Power paid for three segments with topics that included
energy-efficient spring and fall tips and ways to beat the summer heat.
Radio
As part of its spring and fall campaigns, Idaho Power ran 30-second radio spots on major
commercial radio stations in the service area. To obtain optimal reach, the spots ran on a
variety of station formats, including classic rock, news/talk, country, adult alternative, rock,
Residential Sector Overview
Demand-Side Management 2021 Annual Report Page 33
sports, and classic hits. The message was targeted toward adults age 25 to 64 throughout
Idaho Power’s service area.
Results of the spots are provided for the three major markets: Boise, Pocatello, and Twin Falls.
During the spring campaign, Idaho Power ran 2,855 English radio spots. These spots reached
84% of the target audience in Boise, 61% in Pocatello, and 70% in Twin Falls. The target
audience was exposed to the ad 8.7 times in Boise, 8.8 times in Pocatello, and 12.7 times in
Twin Falls. During the fall campaign, the company ran 1,770 English radio spots. These spots
reached 62.2% of the target audience in Boise, 61% of the target audience in Pocatello,
and 66.5% of the target audience in Twin Falls. The target audience was exposed to the
message 5.9 times in Boise, 7.1 times in Pocatello, and 9 times in Twin Falls during the
fall campaign.
In spring, Idaho Power also ran 393 ads on Spanish-speaking radio stations and 313 National
Public Radio (NPR) ads in the service area targeting adults age 25 to 54. The fall campaign
included 304 Spanish ads and 303 NPR ads.
Idaho Power ran 30-second spots with accompanying visual banner ads on Pandora internet
radio, which mobile and web-based devices access. In the spring, records show
672,328 impressions and 494 clicks to the Idaho Power residential energy efficiency web page.
The fall ads yielded 687,073 impressions and 338 clicks.
Print
As part of the campaign, print advertising ran in the major daily and select weekly newspapers
throughout the service area. The company also ran ads in the Idaho Shakespeare Festival
program, Idaho Magazine, Boise and Meridian Lifestyle Magazine, IdaHome Magazine,
and Mirada Magazine (Spanish). As part of the print campaign, digital “homepage takeover”
ads were featured on KTVB.com, idahopress.com, and idahostatesman.com. Homepage
takeover ads fill a homepage with ads from one company for a specific timeframe. The spring
ads highlighted individual energy efficiency tips, such as using the power save setting on
electronics and running ceiling fans counterclockwise for summer. The fall ads featured tips on
minimizing gadgets (use one at a time) and using smart power strips.
In 2021, Idaho Power updated the program information in a spiral-bound guide outlining each
of the residential energy efficiency programs, tips, and resources. The updated guide will be
included in the 2022 Welcome Kits. The previous edition of the guide was included in 2021
Welcome Kits, provided to Weatherization Assistance customers, and shared with customers
who attended events Idaho Power participated in prior to the COVID-19 restrictions.
Social Media
Facebook ads for the 2021 spring and fall energy efficiency campaigns received an average of
24,500 impressions and 309 link clicks per ad (8 total).
Residential Sector Overview
Page 34 Demand-Side Management 2021 Annual Report
Throughout the year, Idaho Power used Facebook and Twitter posts and boosted Facebook
posts for various programs and easy energy efficiency tips for customers to implement at home
and at work.
Out-of-Home
In 2021, Idaho Power participated in several tactics referred to as out-of-home advertising.
Out-of-home advertising attempts to reach customers when they are outside of their homes.
The tactics were a way to continually maintain energy efficiency program awareness
throughout the year. Tactics included full-side bus wraps on three ValleyRide buses in the
Treasure Valley Area that yielded 615,384 impressions. Impressions during the year most likely
varied due to more customers working from home during COVID-19 restrictions but did make a
comeback compared to 2020 since some restrictions were lifted. A full-side bus wrap also ran
on one Pocatello Regional Transit bus in the Eastern Region.
Idaho Power sponsored the Boise Hawks (minor league baseball team) from May through
September. As part of the sponsorship package, Idaho Power received a 15-second digital ad on
the four screens within the stadium. The company’s EE ad was shown a total of 16,416 times
during the 48-game season and total audience attendance was 46,089. The Boise Hawks use a
special TV system called In-Stadium Media (ISM), which can tell how often spectators are
looking at screens. The average interaction/engagement rate was 38.5%, which is on par with
the industry standard of 42%.
Idaho Power also used weather-triggered billboards in Boise, Pocatello, Nampa, and Caldwell.
These are electronic billboards operating in January and July with variable messaging based on
the outside temperatures. This tactic keeps EE top-of-mind and demonstrates simple ways
customers can reduce energy use during extreme weather.
Public Relations
Many of the company’s PR activities focused on the residential sector. Energy-saving tips
videos, TV segments, news releases, and Connections newsletter articles often aim to promote
incentive programs and/or educate customers about behavioral or product changes they can
make to save energy in their homes. Idaho Power also promoted the Touchdown to Energy
Savings contest in News Briefs.
See the Program Activity section and the Commercial and Industrial Sector Overview for more
2021 PR activities.
Empowered Community
In 2015, Idaho Power created the Empowered Community, an online community of residential
customers, to measure customer perceptions on a variety of company-related topics, including
energy efficiency. The community has over 2,000 actively engaged members from across Idaho
Residential Sector Overview
Demand-Side Management 2021 Annual Report Page 35
Power’s service area. Idaho Power typically sends these members between six and 12 surveys
per year. In 2021, Idaho Power included six energy efficiency messages with survey invitations
resulting in nearly 13,500 touchpoints.
Recruitment for the Empowered Community is conducted on an annual basis to refresh the
membership. Throughout February and March 2021, various types of recruitment were
conducted with residential customers, including messages on paperless billing emails, a News
Brief to local media outlets, pop-up ads on My Account, direct emails, and social media posts.
In 2021, 838 new members were added to Empowered Community.
Seasonal Sweepstakes
In 2021, Idaho Power ran two seasonally focused energy efficiency sweepstakes—the Loads of
Energy Savings Summer Giveaway in July and the Touchdown to Energy Savings Fall Giveaway
in November.
Both sweepstakes aimed to maintain awareness about energy efficiency and the impact a small
change can make.
The summer sweepstakes ran July 21–30 and received 5,248 entries. Customers were asked to
comment—through social media or on the Idaho Power website—with a way they saved energy
when doing laundry. In return, participants were entered to win an ENERGY STAR® washer and
dryer set. The sweepstakes was promoted with email messaging to 222,565 customers,
and social media posts reached 27,142 customers, receiving 1,545 engagements (likes,
comments, shares). The sweepstakes was also promoted on idahopower.com through a pop-up
ad on the My Account homepage.
The fall sweepstakes ran November 12–22 and received 2,473 entries. Customers were asked
to comment—through social media or on the Idaho Power website—with a way they saved
energy in the kitchen while making their favorite gameday treats. In return, participants were
entered to win one of 10 air fryers. The sweepstakes was promoted with email messaging to
252,190 customers and paid social media posts reached 9,700 customers, receiving 531 post
engagements. The sweepstakes was also promoted through a pop-up ad on the company’s
My Account homepage. It was featured in News Briefs to media outlets and was promoted on
idahopower.com.
Customer Satisfaction
Idaho Power conducts the Burke Customer Relationship Survey each year. In 2021, on a scale of
zero to 10, residential survey respondents rated Idaho Power 7.99 regarding offering programs
to help customers save energy, and 8.21 related to providing customers with information on
how to save energy and money.
Residential Sector Overview
Page 36 Demand-Side Management 2021 Annual Report
Thirty percent of residential respondents indicated they have participated in at least one Idaho
Power energy efficiency program. Of the residential survey respondents who have participated
in at least one Idaho Power energy efficiency program, 90% were “very” or “somewhat”
satisfied with the program.
Idaho Power customer awareness of energy efficiency programs is among the highest in the
nation: 67% of the residential respondents in the J.D. Power and Associates 2021 Electric Utility
Residential Customer Satisfaction Study indicated they were aware of Idaho Power’s energy
efficiency programs, and on an overall basis, those customers were more satisfied with
Idaho Power than customers who were unaware of the programs. Idaho Power ranked third
out of 17 utilities included in the west region midsize segment of this study.
See the individual program sections for program-specific customer satisfaction survey results.
Field Staff Activities
Idaho Power’s residential and commercial energy advisors and EOEAs started 2021 with
opportunities to conduct in-person meetings and events to promote energy efficiency programs
and offerings with customers. Some areas were still cancelling due to COVID-19 restrictions,
but the company and its energy advisors were able to get out and connect with customers
more than the previous year. During the fall of 2021, energy advisors and other Idaho Power
staff members participated in one of the company’s largest legacy events, the Boise Fall Home
Show. Energy advisors also were able to give in-person presentations throughout the year
across southern Idaho and eastern Oregon. These presentations were for K–6, secondary school
students, and adult audiences.
Energy advisors continued to use phone, email, mail, text, and virtual presentations to stay
connected with customers. The energy advisors created giveaway bags for senior centers that
included an LED lamp, nightlight, energy efficiency information, puzzles, and games.
Energy advisors delivered these items while social distancing and wearing masks to keep
everyone safe.
Though much of 2021 was spent continuing alternative methods for customer interaction,
the changes are allowing the company to offer more training and development sessions for
energy advisors to expand their knowledge, skills, and abilities about energy efficiency
programs, measures, and technologies. Topics included lighting, building envelope, HVAC,
and refrigeration.

Description
Originating in 2003, A/C Cool Credit is a voluntary, dispatchable demand response program for
residential customers in Idaho and Oregon. Using communication hardware and software,
Idaho Power cycles participants’ central A/C units or heat pumps off and on via a direct load
control device installed on the A/C unit. This program enables Idaho Power to reduce system
capacity needs during times when summer peak load is high.
Customers’ A/C units are controlled using switches that communicate by powerline carrier
(PLC) using the same system utilized by Idaho Power’s advanced metering system (AMI).
The switch is installed on each participating customer’s A/C unit and allows Idaho Power to
control the unit during a cycling event.
The cycling rate is the percentage of an hour the A/C unit will be turned off by the switch.
For instance, with a 50% cycling rate, the switch will cycle the A/C unit off for about 30
(nonconsecutive) minutes of each hour. Idaho Power tracks the communication levels to
validate whether the signal reaches the switches. Switch communication may be interrupted
for a variety of reasons: the switch may be disconnected, an A/C unit may not be powered on,
the switch may be defective, or the participant’s household wiring may prevent
communication. Sometimes it is difficult for the company to detect why the switch is not
communicating.
Residential Sector—A/C Cool Credit
Page 38 Demand-Side Management 2021 Annual Report
These are the program event guidelines:
• June 15 through August 15 (excluding weekends and holidays)
• Up to four hours per day
• A maximum of 60 hours per season
• At least three events per season
At the end of the season, Idaho Power or a third party evaluates the events to determine peak
demand savings.
Program Activities
In 2021, about 20,850 customers participated in the program, with approximately 244 in
Oregon and 20,602 in Idaho. Nine cycling events occurred, and all were successfully deployed
(Table 10). The cycling rate was 55%, and the communication level exceeded 90% for each
event. Idaho Power calculated the maximum potential capacity in 2021 to be 29.19 MW at the
generation level. This estimate of the program capacity is based on the maximum per-unit
reduction ever achieved at the generation level of 1.4 kW per participant. The incentive
remained $15 per season, paid as a $5 bill credit on the July, August, and September bills.

Throughout 2021, Idaho Power representatives continued site visits to check switches and
equipment to improve communication levels. COVID-related safety protocols remained in
place, including calling each customer before the visit to explain the process and safety
measures and not visiting any site where the customer was uncomfortable with the process.
While at the site, contractors wore masks, maintained a 6-foot social distance from customers,
and performed enhanced disinfecting activities. Due to these protocols, not all device checks
were completed. The company will continue work to ensure devices associated with the
program are communicating on an ongoing basis.
Residential Sector—A/C Cool Credit
Demand-Side Management 2021 Annual Report Page 39
During the site visits, Idaho Power representatives placed informational stickers on devices that
included a safety warning and toll-free number customers could call with questions.
Marketing Activities
Per the settlement agreement reached in IPUC Case No. IPC-E-13-14 and OPUC Case UM 1653,
Idaho Power did not actively market the A/C Cool Credit program in 2021.
Before the cycling season began, Idaho Power sent current participants a postcard to remind
them of the program specifics. Idaho Power also attempted to recruit customers who had
moved into a home that already had a load control device installed and previous participants
who changed residences to a location that may or may not have a load control device installed.
The company used postcards, phone calls, direct-mail letters, and home visits (leaving door
hangers for those not home) to recruit these customers. Participating customers received a
thank you and a credit reminder message on their summer bills. At the end of the summer,
a thank-you postcard was sent to program participants.
Cost-Effectiveness
Idaho Power determines cost-effectiveness for its demand response program under the terms
of IPUC Order No. 32923 and OPUC Order No. 13-482. Under the terms of the orders and the
settlement, all Idaho Power’s demand response programs were cost-effective for 2021.
The A/C Cool Credit program was dispatched for nine events (totaling 27 event hours) and
achieved a maximum demand reduction of 26.7 MW. The total expense for 2021 was $751,989
and would have remained the same if the program was fully used for 60 hours because there is
no variable incentive paid for events beyond the three required events.
A complete description of the cost-effectiveness of Idaho Power’s demand response programs
is included in Supplement 1: Cost-Effectiveness.
Evaluations
In 2021, Idaho Power contracted a third party to conduct an impact evaluation of the A/C Cool
Credit Program. The evaluator was asked to review the current 3-in-10 baseline methodology
and make recommendations for a demand reduction calculation methodology going forward.
The evaluator recommended a mixed-method approach, in which each home would utilize
non-event “proxy” days to understand which calculation method forecast the homes’ usage
best and produced the lowest bias. Once identified, this calculation method was used for
the home.
Using the mixed-method approach, the evaluator calculated a realization rate of 82.5%,
which is calculated by dividing the achieved hourly demand reduction averaged over every
event hour of the season by the expected household demand reduction. The average reduction
per event was 20.1 MW at the system level. The maximum hour reduction occurred on the
Residential Sector—A/C Cool Credit
Page 40 Demand-Side Management 2021 Annual Report
July 30 event with a reduction of 26.7 MW at the system level. The evaluator also found a
correlation between demand reduction achieved and cooling degree days (CDD) and
recommended calling events based upon forecasted high CDD.
Idaho Power will consider all recommendations made in the report and will report any changes
to the program in the Demand-Side Management 2022 Annual Report. See the complete

Description
As a result of IPUC Case No. IPC-E-08-10 and Order Nos. 30722 and 30754, Idaho Power
committed to fund energy efficiency education for low-income customers and provide
$125,000 to Community Action Partnership (CAP) agencies in its service area annually, on a
prorated basis. These orders specified that Idaho Power provide educational information to
Idaho customers who heat their homes with electricity.
From 2009 to 2017, using CAP agency personnel, the program distributed Energy-Saving Kits
(ESK) and corresponding educational materials to participants of the Low Income Home Energy
Assistance Program (LIHEAP) who heat their homes with electricity. In 2017, with input from a
planning committee consisting of representatives from CAPAI, CAP agencies, IPUC, and Idaho
Power, this program discontinued kit distribution and offered a pilot incentive: a coupon for a
free electric HVAC tune-up and one-on-one education with the goal of helping low-income
customers learn ways to reduce their energy costs and have a maintained HVAC system.
To provide services for the program, regional HVAC company owners sign contractor guidelines
and acknowledge the two-fold goal of the program—customer education and equipment
tune-up. During the customer visit, HVAC contractors perform the tune-up and teach residents
how to change furnace filters. They also explain how regular maintenance improves overall
performance and answer questions about the specific heating equipment and ways to save
energy. The contractor leaves behind information for a customer satisfaction survey that can be

Page 42 Demand-Side Management 2021 Annual Report
completed online or mailed to CAPAI. Respondents are entered into a drawing for a gift card
provided by CAPAI.
Program Activities
Due to COVID-19 restrictions, in-home program activity was suspended until year end. As a
result, in 2021 there were no coupons distributed. However, CAP agencies, the planning
committee, and contractors met virtually throughout the year to plan future program changes.
The group agreed to noteworthy improvements, which will be implemented in 2022.
Idaho Power sent coupons for the 2022 program season to CAP agencies at the end of 2021.
The company also sent helpful energy efficiency education materials that CAP agencies can give
to regional HVAC contractors to share with customers.
Marketing Activities
Idaho Power sent a direct-mail postcard (Figure 8) to Idaho residential customers who received
energy assistance in the previous year to encourage them to take advantage of the program as
in-home activity resumed toward the end of 2021.

Figure 8. Direct-mail postcard to Idaho residential customers for Easy Savings
The Easy Savings program is included under “Savings for Your Home” on the Idaho Power
website in the “Income Qualified Customers” section.
Cost-Effectiveness
Because the Easy Savings program is primarily an educational and marketing program,
the company does not apply traditional cost-effectiveness tests to it.
Residential Sector—Easy Savings: Low-Income Energy Efficiency Education
Demand-Side Management 2021 Annual Report Page 43
No coupons were distributed in 2021 due to the suspension of in-home activities. When the
program resumes in 2022, the program will claim 68.01 kWh for each qualifying customer,
which is based on the 2020 energy efficiency potential study.
2022 Program and Marketing Strategies
In January, the Easy Savings program will execute the changes agreed on in the 2021
planning meetings:
• Eligibility: All income-qualified Idaho Power customers with electric heat are eligible to
participate in the Easy Savings program regardless of whether they had participated in
the LIHEAP/Energy Assistance program.
• Energy-saving services and products: In addition to conducting electric HVAC-related
maintenance and repair, contractors will give customers a year’s worth of furnace
filters, wrap electric water heater pipes, and install “Dusk to Dawn” LEDs in porch light
fixtures as needed. The program will also give participants energy-saving dryer balls,
an air fryer, and/or a counter-top microwave to those who do not have these items.
• Energy education: Contractors will continue to discuss the importance of HVAC
maintenance and incorporate education about saving energy with small appliances and
will answer questions about other ways to save energy in their homes.
Each agency’s portion of the annual $125,000 payment was made in December 2021,
so agencies will begin 2022 with their portion of this payment added to any unspent portion of
previous payments. In 2022, CAP agencies will again provide reporting on redemption of
coupons and energy-saving items.

Description
Designated as a specific program in 2015, the Educational Distributions effort is administered
through the REEEI and seeks to use low-cost and no-cost channels to deliver energy efficiency
items with energy savings directly to customers. As with the initiative, the goal for these
distributions is to drive behavioral change and create awareness of, and demand for,
energy-efficiency programs in Idaho Power’s service area.
Idaho Power selects items for distribution if the initial analysis indicates the measure is either
currently cost-effective or expected to be cost-effective. Typically, selected items have
additional benefits beyond traditional energy savings, such as educating customers about
energy efficiency, expediting the opportunity for customers to experience newer technology,
or allowing Idaho Power to gather data or validate potential energy savings resulting from
behavior change.
Idaho Power recognizes the need to educate and guide customers to promote behavioral
change and awareness and will plan program activities accordingly. Items may be distributed at
events and presentations, through direct-mail, or during home visits conducted by
energy advisors.

Demand-Side Management 2021 Annual Report Page 45
Nightlights as Giveaways
Nightlights are a popular giveaway item with Idaho Power customers and provide another
opportunity to share information about energy efficient LED technology and safe,
energy-efficient ways to provide nighttime lighting. Energy advisors are encouraged to use
nightlights as a bridge to these discussions.
Student Energy Efficiency Kit Program
The SEEK program provides fourth- to sixth-grade students in schools in Idaho Power’s service
area with quality, age-appropriate instruction regarding the wise use of electricity. Each child
who participates receives an energy efficiency kit. The products in the kit are selected
specifically to encourage energy savings at home and engage families in activities that support
and reinforce the concepts taught at school.
Once a class enrolls in the program, teachers receive curriculum and supporting materials.
Students receive classroom study materials, a workbook, and a take home kit containing
the following:
• Three LED lightbulbs
• A high-efficiency showerhead
• An LED nightlight
• A furnace filter alarm
• A digital thermometer for measuring water and refrigerator/freezer temperatures
• A water flow-rate test bag
• A shower timer
At the conclusion of the program, students and teachers return feedback to Idaho Power’s
vendor indicating how the program was received and which measures were installed.
The vendor uses this feedback to provide a comprehensive program summary report showing
program results and savings.
Unlike most residential programs offered by Idaho Power, SEEK results are reported on a school
year basis, not by calendar year.
Welcome Kits
Idaho Power uses a vendor to mail Welcome Kits to brand new customers between 35 and
45 days after electric service begins at their residence. Each kit contains four LED lightbulbs,
a nightlight, a greeting card, and a small flipbook containing energy-saving tips and information
about Idaho Power’s energy efficiency programs. The kits are intended to encourage first-time
customers to adopt energy-efficient behaviors early in their new homes.
Residential Sector—Educational Distributions

Program Activities
Nightlights as Giveaways
Idaho Power continued to distribute LED nightlights to engage customers in discussions around
energy-efficient behavior changes and home upgrades.
In-person events continued to be curtailed due to Covid-19 concerns throughout the year;
however, by year-end, Idaho Power staff and energy advisors distributed 2,378 nightlights
along with an educational message. Nightlights were distributed to VIPs, sponsors, business and
community leaders, veterans at over 25 American Legion and VFW organizations, rural senior
centers, participants of the Pride Fest in Boise on Sept 10–12, and during presentations to
civic organizations.
Student Energy Efficiency Kit Program
During the 2020 to 2021 school year, the vendor was responsible for SEEK recruiting activities.
Idaho Power EOEAs continued to promote the program during their school visits and
interactions with fourth to sixth grade teachers. Despite some continued school closures and
online delivery, SEEK enrollments were strong. The vendor delivered 12,446 kits to
453 classrooms in 189 schools within Idaho Power’s service area. This resulted in 2,167 MWh
of savings.
In 2021, the company issued a request for proposals (RFP) from kit vendors for new kit options
and costs for the upcoming school year. Although the 2021 vendor had been an excellent
contractor to work with, the proposal team ultimately selected a new vendor.
In 2020, the SEEK Program was part of a third-party evaluation. One of the
recommendations included:
• For SEEK, if practical, consider allowing students to take pictures of the
replaced/baseline equipment as a way of confirming/vetting the answers they provide
on the survey. The primary factor in selecting a new vendor was because of the ability to
help transition the curriculum to a digital platform. The new curriculum will also
incorporate opportunities for students to participate in a video contest and provide
photo documentation of installed kit items.
Welcome Kits
Idaho Power continued to contract with a third-party vendor to distribute energy efficiency kits
to the company’s first-time customers. In 2021, after collaboration with EEAG, the kit contents
were adjusted to improve cost-effectiveness. Rather than four 800-lumen bulbs, each recipient
received two 800-lumen and two 1600-lumen LED bulbs.
The company sent nearly 32,700 Welcome Kits to customers in 2021—similar to the quantity
delivered in previous years.
Residential Sector—Educational Distributions
Demand-Side Management 2021 Annual Report Page 47
In 2020, the Welcome Kits were part of a third-party evaluation. One of the
recommendations was:
• Consider additional research to better estimate the number of Welcome Kit recipients
who take kit measures with them when they move. Although the company considered
this recommendation, it did not move forward with additional research in 2021.
Welcome Kit LED bulb savings rely on the RTF deemed savings which factor in storage
and removal rates. Additionally, LEDs delivered through other channels, such as retail or
direct install use the RTF deemed savings values, and the RTF has not factored in a
discount due to participant subsequently relocating or transporting measures outside a
utility’s service area. While Idaho Power may potentially include this research in a future
evaluation, it is likely that the risk is relatively small and may be offset by new customers
to Idaho Power’s service area who may be transporting energy efficient items into
the area.
Idaho Power continues to receive positive customer feedback indicating these kits are
well-received.
Marketing Activities
Nightlights as Giveaways
Nightlights are not marketed as a separate measure, but energy advisors used them to facilitate
energy efficiency conversations during customer visits.
Student Energy Efficiency Kit Program
During the 2020–2021 school year, the vendor staff handled most of the marketing and
recruitment of teachers via email and phone calls to the eligible schools. Idaho Power EOEAs
continued to promote the program through the Community Education Guide and in
conversations with teachers throughout the year.
Welcome Kits
The Welcome Kits are not requested by customers; therefore, they are not marketed. Instead,
each week Idaho Power sends a list of new customers to the vendor to fulfill the order. The kits
are, however, used to cross-market other programs through the inclusion of a small flipbook
containing energy-saving tips and information about Idaho Power’s energy efficiency programs.
Cost-Effectiveness
In situations where Idaho Power managed energy efficiency education and distribution through
existing channels, the cost-effectiveness calculations were based on the actual cost of the
items. In 2021, the Welcome Kits were not fully cost-effective due to additional erosion of
lighting savings. After consulting the EEAG, the decision was made to keep this educational
program, but to only include the cost-effective portion associated with those energy savings in
Residential Sector—Educational Distributions
Page 48 Demand-Side Management 2021 Annual Report
the Educational Distribution program and the remainder of the kit costs are included in the
Residential Energy Efficiency Education Initiative budget.
The UCT and TRC for the program is 2.39 and 3.10 respectively.
Nightlights as Giveaways
Idaho Power used the third-party evaluator’s calculated savings of 12 kWh per nightlight as
explained in the Welcome Kit cost-effectiveness section.
Student Energy Efficiency Kit Program
In 2020, the SEEK Program was part of a third-party evaluation. Three of the
recommendations were:
• Continue to not claim savings from the shower timers.
• Assume 13 watts (W) for baseline wattage for “Other” bulbs for SEEK lighting
saving calculations.
• Ask the SEEK vendor to provide a spreadsheet or code used to calculate savings.
The cost-effectiveness analysis for the SEEK offering was based on the savings reported by the
kit provider during the 2020 to 2021 school year. The kit provider calculated the annual savings
based on information collected from the participants’ home surveys and the installation rate of
the kit items. Questions on the survey included the number of individuals in each home,
water-heater fuel type, flow rate of old showerheads, and the wattage of any replaced
lightbulbs. The response rate for the survey was approximately 32%. The survey gathers
information on the efficiency level of the existing measure within the home and which measure
was installed. The energy savings will vary for each household based on the measures offered
within the kit, the number of items installed, and the existing measure that was replaced.
Idaho Power adopted the recommendations from the evaluation. The company continued not
to claim savings for the shower times, received the spreadsheet the vendor used to calculate
savings, and confirmed the baseline wattage of 13W for the “other” bulb types. Based on the
feedback received from the 2020 to 2021 school year, the savings for each kit was
approximately 174 kWh annually per household on average, and the program saved
2,166,583 kWh annually. A copy of the report is included in Supplement 2: Evaluation.
Welcome Kits
For the two 800-lumen LED lightbulbs included in the kit, Idaho Power used the RTF’s giveaway
deemed savings value of 0.71 kWh per bulb. For the two 1600-lumen LED bulbs, Idaho Power
used the RTF’s giveaway deemed savings value of 4.72 kWh per bulb. For the nightlight,
Idaho Power used the third-party evaluator’s calculated savings of 12 kWh per nightlight, which
were identified using survey data as part of a 2020 evaluation. The annual savings for each kit is
22.86 kWh.

Demand-Side Management 2021 Annual Report Page 49
Evaluations
In 2021, Idaho Power considered the recommendations from the 2020 process and impact
evaluations conducted by a third party. See the recommendations and Idaho Power’s
responses above.
2022 Program and Marketing Strategies
Nightlights as Giveaways
Nightlights will continue to be the primary opportunity to garner savings in conjunction with
educational discussions and customer conversations. Field staff will look for opportunities to
discuss LED technology and savings, encourage in-home adoption of LED lighting, and promote
the use of LED nightlights as an energy efficient, safe nighttime lighting option.
Student Energy Efficiency Kit Program
Idaho Power will continue to offer the SEEK program. The company will work with the new
vendor to transition the curriculum and teacher/student interface to a more digital-friendly
delivery system with additional opportunities for student engagement.
The company will continue to leverage the positive relationships Idaho Power’s EOEAs have
within the schools to maintain program participation levels. Idaho Power will continue to work
with the new SEEK program vendor, responding to feedback and input from teachers and
parents regarding the new online delivery format.
Welcome Kits
Idaho Power will continue to offer Welcome Kits to first-time customers. In 2022, the kit
contents will be adjusted to take advantage of the RTF savings associated with 1100-lumen
bulbs. The Welcome Kit will cross-promote other energy efficiency programs and educate and
encourage new customers to adopt energy-efficient behaviors upon moving into their new
homes. The Educational Distributions program will continue to count the savings and pay for
the cost-effective energy saving portion of each kit, while the remaining costs associated with
the kits will be included in Idaho Power’s REEEI efforts.
Other Educational Distributions
Idaho Power will continue to look for opportunities to engage customers with new technologies
that stress the importance of energy-efficient behaviors at home. The online marketplace Idaho
Power is considering for 2022 may serve as an avenue to engage and educate customers while
promoting efficient technologies that may not fold neatly into other program offerings.

Description
Initiated in 2002, the Energy House Calls program gives homeowners of electrically heated
manufactured homes an opportunity to reduce electricity use by improving the home’s
efficiency. Specifically, this program provides free duct sealing and additional efficiency
measures to Idaho Power customers living in Idaho or Oregon who use an electric furnace or
heat pump. Participation is limited to one service call per residence for the lifetime of the
program.
Services and products offered through the Energy House Calls program include duct testing and
sealing according to Performance Tested Comfort System (PTCS), standards set and maintained
by BPA; installing LED lightbulbs; testing the temperature set on the water heater; installing
water heater pipe covers when applicable; installing one bathroom faucet aerator, one kitchen
faucet aerator; and leaving two replacement furnace filters with installation instructions, as
well as energy efficiency educational materials appropriate for manufactured home occupants.
Idaho Power provides contractor contact information on its website and marketing materials.
The customer schedules an appointment directly with one of the certified contractors in their
region. The contractor verifies the customer’s initial eligibility by testing the home to determine
if it qualifies for duct sealing. Additionally, contractors have been instructed to install LED
lightbulbs only in exterior, moderate and high-use areas of the home; to replace only
Residential Sector—Energy House Calls
Demand-Side Management 2021 Annual Report Page 51
incandescent and halogen lightbulbs; and to install bathroom aerators and showerheads only if
the upgrade can be performed without causing damage to a customer’s existing fixtures.
The actual energy savings and benefits realized by each customer depend on the measures
installed and the repairs and/or adjustments made. Although participation in the program is
free, a typical cost for a similar service call would be $400 to $600, depending on the
complexity of the repair and the specific measures installed.
Program Activities
In response to COVID-19 restrictions and to ensure the safety of customers and contractors,
visits to customer homes for the Energy House Calls program were suspended much of the
year. In 2021, 11 homes received products and/or services through this program (Figure 9),
resulting in 14,985 kWh savings. Of the total participating homes, 100% were in Idaho Power’s
South–East Region.
Once in-home visits resumed in late November, approximately 125 homes were on waitlists to
participate in the program. Due to supply chain issues, the contractors had difficulty finding
crossovers to repair damaged crossovers on double-wide and triple-wide homes. This delay
extended times to complete the orders that were already on hold due to COVID-19. According
to contractors, all requests for an Energy House Calls visit should be completed by March 1,
2022, if the necessary materials to complete the jobs can be obtained.

Figure 9. Participation in the Energy House Calls program, 2012–2021
Duct-Sealing
Each year, several customers who apply for the Energy House Calls program cannot be served
because their ducts do not require duct-sealing or cannot be sealed, for various reasons.
These jobs are billed as a test-only job. On some homes, it is too difficult to seal the ducts, or

the initial duct blaster test identifies the depressurization to be less than 150 cubic feet per
minute (cfm), and duct-sealing is not needed. Additionally, if after sealing the duct work the
contractor is unable to reduce leakage by 50%, the contractor will bill the job as a test-only job.
Prior to 2015, these test-only jobs were not reported in the overall number of jobs completed
for that year because they included no kWh savings. Because Idaho Power now offers direct-
install measures in addition to the duct-sealing component, all homes are reported. While some
homes may not have been duct-sealed, all would have had some of the direct-install measures
included, which would allow Idaho Power to report kWh savings for those homes. Of the 11
homes that participated in 2021, none were serviced as test only.
If a home had a blower door and duct blaster test completed, and the contractor determined
that only duct-sealing is necessary, it was billed as a test and seal. For a multi-section home
with an x-over duct system (one that transfers heated or cooled air from one side to the other)
that needs replaced in addition to the duct-sealing, it is charged as an x-over. When a home
requires the existing belly-return system to be decommissioned and have a new return installed
along with the duct sealing, it is billed as a complex system. A complex system that also requires
the installation of a new x-over and duct sealing is billed as a complex system and x-over job.
Figure 10 shows the job type percentages (Test and Seal versus x-over) for the 2021 Energy
House Calls program.

Figure 10. Energy House Calls participation by job type
Direct-Install Measures
In 2021, contractors installed 63 LED lightbulbs, no showerheads, no bathroom aerators, and
two kitchen aerators.
Marketing Activities
Due to program inactivity for most of the year, all marketing efforts were suspended, except for
a shared bill insert with Rebate Advantage sent to all residential customers in May and
November 2021 (Figure 11). The May insert was sent to 302,353 customers, and the November
91%
9%
Residential Sector—Energy House Calls
Demand-Side Management 2021 Annual Report Page 53
insert was sent to 296,992 customers. Customers who requested an energy house call while
in-home work was on hold were added to a waitlist and were contacted in November to
schedule a visit once in-home work resumed.

Figure 11. Energy House Calls bill insert
While in-home work was on hold, Idaho Power added an alert to the Energy House Calls web
page to let customers know of the delay for scheduling home visits.
Cost-Effectiveness
The UCT and TRC ratios for the program are 0.43 and 0.50, respectively. The program’s
cost-effectiveness was impacted by the updated savings assumptions coupled with the
suspension of in-home visits due to COVID-19 from March 2020 through November 2021.
In 2021, Idaho Power used the same RTF savings for duct-sealing in manufactured homes as
were used in 2020. In December 2021, the RTF reviewed and updated the savings associated
with manufactured home duct sealing based on program evaluations around the region.
For 2022, Idaho Power plans to use the updated savings of 888 kWh per home.
Savings for the LED lightbulbs decreased from 30.63 kWh to 5.65 kWh based on updated
lighting assumptions for the RTF. In 2020, the RTF reviewed the savings associated with
low-flow showerheads. Because of the uncertainty around the relationship between the hot
Residential Sector—Energy House Calls
Page 54 Demand-Side Management 2021 Annual Report
water savings and the low-flow showerhead and the increasing efficiency for showerheads in
the region due to codes and standards, the RTF deactivated the low-flow showerhead measure.
Therefore, there are no savings associated with low-flow showerheads. Additionally, the RTF
reviewed aerator savings in 2021. Like the showerheads, there was uncertainty with the savings
associated with aerators and the RTF deactivated the measure. While the savings for low-flow
faucet aerators remain the same between 2020 and 2021, there will be no savings associated
with the aerators in 2022.
Because the program would have likely remained cost-effective in 2021 had in-home work not
been suspended, Idaho Power will continue to work through the homes that remain on the
waitlist. Due to the lower savings associated with duct sealing and LED lightbulbs and the
removal of the showerhead and faucet aerator savings, cost-effectiveness will continue to be a
challenge for the current program model in 2022.
For more detailed information about the cost-effectiveness savings and assumptions,
see Supplement 1: Cost-Effectiveness.
2022 Program and Marketing Strategies
Idaho Power will continue to provide free duct sealing and selected direct-install efficiency
measures for all-electric manufactured/mobile homes in its service area as long as the program
is operational. Due to cost-effectiveness constraints, the Energy House Calls program as a
stand-alone program is no longer cost-effective. Idaho Power will continue to work with
stakeholders, including EEAG, to determine the best course of action for Energy House Calls in
2022.

home with an electric forced-air heating system or a heat pump is $350.
• Electronically commutated motor (ECM): The customer incentive for replacing a permanent
split capacitor (PSC) air handler motor with an ECM in an existing home with oil or propane
or natural gas forced-air heat, electric forced-air heat, or a heat pump is $50. A $150
incentive is paid to the licensed contractor.
• Evaporative cooler: The customer incentive for installing an evaporative cooler is $150.
• Heat pump water heater (HPWH): The customer incentive for installing an HPWH is $300.
• Smart thermostat: The customer incentive for a smart thermostat installed in an existing
home with an electric forced-air furnace or a heat pump is $75.
• Whole-house fan (WHF): The customer incentive for a WHF installed in an existing home
with central A/C, zonal cooling, or a heat pump is $200.
Measures, Conditions, and Incentives/Stipends for New Homes
• Ducted air-source heat pump: The incentive for homeowners, property owners, or builders
of new construction installing a ducted air-source heat pump in a new home is $400 for a
minimum efficiency 8.5 HSPF. A $50 stipend is paid to the participating contractor.
Participating homes must be where natural gas is unavailable.
• Ducted open-loop water-source heat pump: The incentive for homeowners, property
owners, or builders of new construction installing a ducted open-loop water-source heat
pump in a new home is $1,000 for a minimum efficiency 3.5 COP. A $50 stipend is paid to
the participating contractor. Participating homes must be where natural gas is unavailable.
Idaho Power requires licensed contractors to perform the installation services related to these
measures, except evaporative coolers, HPWH, and smart thermostats. To qualify for the heat
pump and duct-sealing incentive, an authorized participating contractor must perform the
work. To be considered a participating contracting company, an employee from the contracting
company must first complete Idaho Power’s required training regarding program guidelines and
technical information on HVAC equipment.
Residential Sector—Heating & Cooling Efficiency Program
Demand-Side Management 2021 Annual Report Page 57
A third-party contractor reviews and submits incentive applications for payment using a
program database portal developed by Idaho Power. The contractor also provides technical and
program support to customers and contractors and performs on-site and off-site verifications.
Program Activities
The 2021 H&CE Program paid incentives are listed in Table 11. The third-party contractor
performed random off-site verifications on 5% of the completed installations. The verifications
were performed via phone and email due to COVID-19 restrictions. These verifications
confirmed the information submitted on the paperwork matched what was installed at
customers’ sites. Overall, the verification results were favorable.
Supporting, developing, and expanding Idaho Power’s authorized participating contractor
network remained a key growth strategy for the program. In 2021, company representatives
met with several prospective contractors to support this approach. As a result, Idaho Power
added seven new contractors to the program in 2021.

In 2020, Idaho Power conducted an exercise, described as journey mapping, with a team of
fellow employees who met periodically for three months to identify difficulties customers
might experience when participating in the program. Recommendations included new layouts
for the program’s 10 application forms. Idaho Power updated one of the 10 forms in 2021 with
the balance to be completed in 2022 using an improved editing process.
In 2019, Idaho Power and other stakeholders began a regional Smart Thermostat Research
Study to collect and provide regional smart thermostat performance data to the RTF. The final
report was published in November 2021. The data in the report will assist the RTF in
determining energy savings for smart thermostats.
Residential Sector—Heating & Cooling Efficiency Program

Marketing Activities
Idaho Power used multiple marketing methods for its H&CE Program in 2021, focusing efforts
toward the hottest and coldest times of the year.
Idaho Power sent two program-related postcards to a targeted customer group that uses
electric heat: 8,087 customers received postcards in February and September. The company
mailed a bill insert to 304,389 residential customers in April and 298,024 residential customers
in September.
In February, the company emailed information about the H&CE Program to approximately
217,000 residential customers. The promotion was opened by over 85,000 customers and
received approximately 5,200 click throughs to the H&CE Program web page. Idaho Power also
sent an email promotion in September to 232,211 residential customers; the email was opened
by over 79,000 customers and received 4,812 click throughs to the web page.
In February and September, Idaho Power used an ad agency to send digital display ads to
customers based on their internet browsing preferences. Using Google Analytics, the ad agency
determined the ads resulted in 2,450,361 impressions and 10,072 clicks to the H&CE Program
web page in February and 3,124,373 impressions and 12,311 web clicks in September.
The company held a smart thermostat giveaway at the September Women and Leadership
Conference. Program information was also included in energy efficiency collateral mailed in the
new customer Welcome Kits.
Smart thermostats were also promoted in a News Briefs in December. The summer edition of
the Energy Efficiency Guide distributed through local newspapers featured a call-out on smart
thermostats. A pop-up graphic ran in the company’s online My Account platform in February
directing customers to the H&CE Program landing page. There were 3,675 click throughs on the
promotion.
Additionally, the program specialist continued to distribute flyers, called tech sheets,
to interested customers and contractors. The eight different flyers are especially beneficial as
sales tools for contractors, for use at trade shows, and as mailers to customers without internet
access who seek program and individual cash incentive information.
Cost-Effectiveness
In 2021, the H&CE Program had a UCT of 1.14 and TRC of 0.36. While participation slightly
increased in 2021 relative to 2020, much of the decrease in cost-effectiveness can be attributed
to a decrease in the RTF measure savings. In 2021, savings were decreased for DHPs, and heat
pump conversions and upgrades, which made up ~61% of the 2021 program savings. In 2021,
Idaho Power added tier 4 efficiency HPWH to the program.
Residential Sector—Heating & Cooling Efficiency Program
Demand-Side Management 2021 Annual Report Page 59
Some measures within the program do not pass the UCT; however, these measures, with the
exception of DHPs, would pass the UCT if administration costs were not included in the
measure’s cost-effectiveness. Most measures are not cost-effective from a TRC perspective.
The program itself has a cost-effectiveness exception with the OPUC under UM 1710.
The program will be modified in 2022 to incorporate the updated savings assumptions,
new measures, and recommendations from the 2021 evaluation.
For detailed information about the cost-effectiveness savings, sources, calculations,
and assumptions, see Supplement 1: Cost-Effectiveness.
Evaluations
In 2021, Idaho Power contracted a third party to conduct an impact and process evaluation of
the H&CE Program. Idaho Power also asked the evaluator to conduct additional detailed
research on many of the measures within the program.
The evaluation found a smooth-running program with high levels of customer satisfaction that
delivers sufficient energy efficiency options to customers. The evaluators calculated a
realization rate of 96.4%. The evaluators provided recommendations to improve the data
collection strategies and the savings calculation process. They also provided recommendations
to reduce barriers for contractor participation and improve the reach of the program
to customers.
Idaho Power will consider all recommendations made in the report, and any changes to the
program will be reported in the Demand-Side Management 2022 Annual Report. See the complete
analysis report in Supplement 2: Evaluation.
2022 Program and Marketing Strategies
Idaho Power will continue to provide program training to existing and prospective contractors
to assist them in meeting program requirements and further their product knowledge.
Training remains an important part of the program because it creates the opportunity to invite
additional contractors into the program, is a refresher for contractors already participating in
the program, and helps them increase their customers’ participation while improving the
contractors’ work quality and program compliance.
Idaho Power’s primary goals in 2022 are to develop contractors currently in the program while
adding new contractors, as program performance is substantially dependent on the
contractors’ abilities to promote and leverage the measures offered. To meet these goals,
the program specialist will frequently interact with contractors in 2022 to discuss the program.
Ground-source heat pumps and central A/C will be reviewed by Idaho Power for inclusion into
the program. Factors including market readiness, supply chain availability, customer demand,
installer availability, and cost-effectiveness will be assessed. The measures have been
Residential Sector—Heating & Cooling Efficiency Program
Page 60 Demand-Side Management 2021 Annual Report
considered in past years but were not added to the program due to less than favorable TRC
results. If Idaho Power determines these two measures have satisfactory UCT results,
the measures will be added to the program during 2022.
The 2022 marketing strategy will include bill inserts, direct-mail, social media, digital and search
advertising, and email marketing to promote individual measures as well as the
overall program.

Description
Under the Home Energy Audit program, a certified, third-party home performance specialist
conducts an in-home energy audit to identify areas of concern and provide specific
recommendations to improve the efficiency, comfort, and health of the home. The audit
includes a visual inspection of the crawlspace and attic, a health and safety inspection, and a
blower door test to identify and locate air leaks. The home performance specialist collects
information on types and quantities of appliances and lighting in each home, then determines
which available energy efficiency measures are appropriate. Homeowners and/or landlords
approve all direct-install measures prior to installation, which could include the following:
• Up to 20 LED lightbulbs
• One high-efficiency showerhead
• Pipe insulation from the water heater to the home wall (approximately 3 feet)
• Tier 2 Advanced Power Strip
The home performance specialist collects energy-use data and records the quantity of
measures installed during the audit using specialized software. After the audit, the auditor
writes up the findings and recommendations, and the software creates a report for
the customer.
Residential Sector—Home Energy Audit
Page 62 Demand-Side Management 2021 Annual Report
To qualify for the Home Energy Audit program, a participant must live in Idaho and be the Idaho
Power customer of record for the home. Renters must have prior written permission from the
landlord. Single family site-built homes, duplexes, triplexes, and fourplexes qualify,
though multifamily homes must have discrete heating units and meters for each unit.
Manufactured homes, new construction, or buildings with more than four units do not qualify.
Interested customers fill out an application online. If they do not have access to a computer,
or prefer talking directly to a person, Idaho Power accepts applications over the phone.
Participants are assigned a home performance specialist based on geographical location to save
travel time and expense.
Participating customers pay $99 (all-electric homes) or $149 (other homes: gas, propane,
or other fuel sources) for the audit and installation of measures, with the remaining cost
covered by the Home Energy Audit program. The difference in cost covers the additional testing
necessary for homes that are not all-electric. These types of energy audits normally cost $300
or more, not including the select energy-saving measures, materials, and labor. The retail cost
of the materials available to install in each home is approximately $145.
Each year, the quality assurance (QA) goal for the program is to inspect 5% of all audits.
Program Activities
Due to COVID-19 restrictions, Idaho Power suspended in-home audits in mid-March 2020 and
was able to resume work in late October 2021. This greatly impacted the number of audits
completed and associated savings. During the in-home work suspension, the program remained
operational, and the company continued to accept enrollments and contacted customers to
explain the delay.
Two home performance specialist companies served the program in 2021 and completed 37
energy audits. House size ranged from 1,000 square feet (ft2) to 4,864 ft2, with the average size
of 2,341 ft2. Houses were built from 1910 to 2020, with an average age of 38 years.
Figure 12 depicts the program’s reach across Idaho Power’s service area, and Figure 13
depicts the space and water heating fuel types. Figure 14 indicates the total quantity of
direct-install measures.
Because in-home activity was suspended most of the year, QAs were not performed.

Marketing Activities
Due to COVID-19 restrictions, Idaho Power suspended marketing efforts as of mid-March 2020.
Enrollments continued to come in during the suspension of in-home work and were tracked on
a waitlist. There were approximately 450 customers on the waitlist when the in-home
work resumed.

In March 2021, a bill insert was sent to 24,514 residential customers to help maintain program
visibility. A disclaimer was included to let customers know they’d be signing up for the waitlist
and contacted when in-home visits resumed.
In November, Idaho Power again collaborated with the University of Idaho’s (U of I) Valley
County Extension Office to host a virtual energy efficiency workshop for customers in Valley
county. The company sent letters and emails and used a Facebook post to invite residents to
attend the workshop, which was scheduled in the evening and was well received. Fifteen
residents registered for the workshop, and eight attended. The U of I saved the recording so it
can be viewed by interested parties in the future and allow the educational program to live on.
Attendees learned how to check their homes for efficiency, how to make some improvements,
incentives available through Idaho Power, and how a professional energy assessment could
lead to improved energy efficiency. Customers expressed appreciation during the event for
being able to have the workshop despite COVID-19 restrictions.
Customers who enrolled in the Home Energy Audit program throughout the year were asked
where they heard about the program. Responses included the following: information in the
mail, 24.43%; family member or friend, 10.42%; Idaho Power employee, 11.40%; social media,
1.63%; other, 52.12%.
Cost-Effectiveness
One of the goals of the Home Energy Audit program is to increase participants’ understanding
of how their home uses energy and to encourage their participation in Idaho Power’s energy
efficiency programs. Because the Home Energy Audit program is primarily an educational and
marketing program, the company does not utilize the traditional cost-effectiveness tests.
For the items installed directly in the homes, Idaho Power used the RTF savings for direct-install
lightbulbs, which range from 4.68 to 17.59 kWh per year. This was a decrease over the
2020 lightbulb savings, which ranged from 16 to 46 kWh per year depending on lightbulb type
and installation location.
In Idaho Power’s Energy Efficiency Potential Study, it is estimated that pipe wraps save 76 kWh
per year. Savings for pipe wrap are counted for homes with electric water heaters.
In 2020, the RTF reviewed the savings associated with low-flow showerheads. Because of the
uncertainty around the relationship between the hot water savings and the low-flow
showerhead and the increasing efficiency for showerheads in the region due to codes and
standards, the RTF deactivated the low-flow showerhead measure. Therefore, there are no
savings associated with low-flow showerheads.
While Idaho Power does not calculate a cost-effectiveness ratio for the Home Energy Audit
program, the savings benefits and costs associated with direct-install measures have been
Residential Sector—Home Energy Audit
Demand-Side Management 2021 Annual Report Page 65
included in the sector and portfolio cost-effectiveness. Idaho Power also converted the 76 kWh
of pipe wrap savings to 2.59 therms and those gas savings are included in the sector and
portfolio cost-effectiveness.
2022 Program and Marketing Strategies
Due to the large number of applicants on the waitlist, the program won’t be marketed while
contractors work through the list. The waitlist will be worked through as quickly as possible,
in the order applications were received. Once most customers have been served, Idaho Power
will resume recruiting participants through small batches of targeted direct-mailings,
social media posts, advertising, and bill inserts. Additional digital advertising may be considered
if the program needs to be strategically promoted in specific regions.

Description
The objective of the HER Program is to encourage customers to engage with their home’s
electricity use in attempt to produce average annual behavioral savings of 1 to 3%. The
program also promotes customer use of online tools and participation in other energy
efficiency programs. Prior to 2021, Idaho Power worked with a third-party contractor and
operated the HER Program under the Educational Distributions program umbrella. In 2021,
the HER Program became a stand-alone energy efficiency program.
Participants receive periodic reports with information about how their homes’ energy use
compares with similar homes. The Home Energy Reports also give a breakdown of household
energy use and offer suggestions to help customers change their energy-related behaviors. The
program contractor estimates energy savings by completing a statistical comparison of the
energy used by customers who receive the reports against the energy used by a control group.
Since the savings estimates rely on the integrity of the experimental design, participants in both
the treatment (those receiving reports) and the control group are selected through a process of
randomization.
Residential Sector—Home Energy Report Program
Demand-Side Management 2021 Annual Report Page 67
Program Activities
In 2021, the HER pilot participants and the expansion participants were integrated into one
report delivery schedule—with each participant receiving quarterly reports in the months of
February, May, August, and November.
In addition to showing participants how their energy compared relative to similar homes,
the February reports delivered energy-saving ideas focused on appliances and lighting.
August reports offered either laundry tips or additional cooling tips. The May and November
reports were segmented between participants with weather-related usage and those whose
energy use was less affected by weather. In May, customers with significant A/C use during the
previous summer received tips to reduce upcoming cooling bills. In November, customers with
electric space heating received information regarding their previous winter’s use along with
heating tips.
In August, Idaho Power and the program vendor made a concerted effort to improve Home
Energy Reports by obtaining and incorporating missing home size information for 14,838
participants. Idaho Power and the program vendor were able to fill some of the gap with
information available from public sources. Those participants still missing data received an
insert (Figure 15) and a follow-up email requesting this information. The effort resulted in
getting accurate home size information to improve the reports and home comparisons for an
additional 10,075 participants.
Residential Sector—Home Energy Report Program
Page 68 Demand-Side Management 2021 Annual Report

Figure 15. Home Energy Report insert requesting more home size information
The HER Program was part of an Educational Distributions program process evaluation in 2020.
Now a stand-alone program, Idaho Power responded to these HER-specific recommendations
in 2021:
• DNV recommends that the vendor update its data tracking to reflect additional
treatments and conduct tests that include the original and additional treatments.
• Before an impact evaluation, the vendor should append dates that households went
inactive and/or moved out.
In response to these recommendations, Idaho Power asked the program vendor to review its
data tracking and prepare documentation showing sequential HER activity, including dates
households went inactive and/or moved out, from the date a customer was initially assigned as
either a treatment or control participant through the present day. Idaho Power contracted with
a third-party consultant to review this documentation and confirm it was complete.
Additionally, Idaho Power facilitated meetings between the consultant and the program vendor
Residential Sector—Home Energy Report Program
Demand-Side Management 2021 Annual Report Page 69
to confirm the methodology and data sets used to estimate 2021 savings aligned with industry
best practice.
• Ask the vendor to remove old data from its FTP folders and implement a process to
remove data from such locations as soon as possible after the data transfer is complete.
Then confirm the deletion. Idaho Power established parameters for retention of data on
the vendor’s FTP site and worked with the vendor to establish a process to remove the
data based on the retention schedule.
In 2021, the savings results for the pilot participants identified as electric heating customers
were not statistically significant as stand-alone cohorts; however, these participants did
contribute to the overall program savings. The new participants joining the program in 2020
saw increases in both their savings percentage and kWh savings per customer, increasing from
0.56% to 0.98% and from 39.67 kWh to 144.28 kWh, respectively. On average, the combined
group of participants used an average of 151.5 fewer kWh per home than their control group
counterparts. When viewed in aggregate, the estimated savings for all program participants
was about 1% below their respective control groups, for a total of 16,667 MWh. To target
customers with higher savings potential, a small group of customers received their last report in
February of 2020; however, this group continued to demonstrate persistent savings. With their
results included, total 2021 program savings totaled 16,767 MWh. On average, program
participants are providing savings at between 36 to 303 kWh annually per home.
Idaho Power’s customer solutions advisors responded to 660 HER Program-related phone calls
during the year. Given that 445,841 reports were delivered, this represents a call rate of just
under 0.15%. The participant-driven opt-out rate in 2021 was 0.17%—significantly lower than
the industry average of 1%. Overall attrition in 2021 was 7.82%--down slightly from 9.4% in
2020 (includes opt-outs, move-outs, etc.).
Marketing Activities
Because the HER Program is based on a randomized control trial (RCT) methodology, the
reports cannot be requested by customers, therefore the program is not marketed. The
periodic reports were, however, used to cross-market Idaho Power’s other energy efficiency
programs. Care was taken to promote programs and offerings currently available to customers
given ongoing safety concerns due to COVID-19. Customers continued to be encouraged to sign
up for My Account alerts in 2021.
Cost-Effectiveness
HER savings are calculated each year using measured usage of the customers receiving the
reports relative to a statistically similar control group that does not receive the reports. Due to
the potential of double-counting savings from other programs, Idaho Power discounts the
Home Energy Report Program savings of 16,767,446 kWh by 5% to report savings of
Residential Sector—Home Energy Report Program
Page 70 Demand-Side Management 2021 Annual Report
15,929,074 kWh. This percentage will be reviewed as part of the planned 2022 impact
evaluation. Based on the reported savings of 15,929 MWh, the UCT and TRC for the program
are 0.57 and 0.62, respectively, for 2021.
Due to the continuous nature of the HER program with costs and savings extending over
numerous years for the same participants, a program life look at cost-effectiveness is utilized to
understand the cost-effectiveness of the program as a whole. The analysis uses 2020 as the
start year and assumes the program continues to send reports until the current contract ends in
2023. From this point savings per participant decrease at 20% per year for another three years,
where it is assumed the treatment no longer impacts the participants. Total participation also
declines at 10% per year, which is the approximate observed annual attrition for the program.
The RTF recently proposed guidelines for reviewing cost-effectiveness for behavioral programs.
The company has done an initial review of these guidelines and incorporated concepts into the
lifetime cost-effectiveness analysis. This lifetime analysis calculates UCT and TRC ratios of 0.87
and 0.96, respectively.
For more detailed information about the cost-effectiveness savings and assumptions, see
Supplement 1: Cost-Effectiveness.
Customer Satisfaction
In September, Idaho Power invited customers in the treatment group and the control group to
participate in a customer satisfaction survey. The purpose of the survey was to evaluate the
customer’s overall satisfaction with Idaho Power and the efforts taken to reduce electricity use
in their home. Customers that were part of the treatment group were asked additional
questions regarding the Home Energy Report they received.
Idaho Power received 1,069 responses from the treatment group and 505 responses from the
control group. Some highlights include the following:
• Nearly 86% of treatment group respondents and over 84% of control group respondents
are satisfied with Idaho Power.
• Nearly 85% of treatment group respondents and nearly 86% of control group
respondents are motivated to reduce electricity in their home.
• Over 91% of treatment group respondents and nearly 90% of control group respondents
have made efforts to reduce electricity use in their home.
• Approximately 66% of treatment group respondents and almost 63% of control group
respondents agreed that Idaho Power provides helpful tools to help them save energy.
Residential Sector—Home Energy Report Program
Demand-Side Management 2021 Annual Report Page 71
• Approximately 70% of treatment and control group respondents agreed that Idaho
Power helps them save energy by providing useful energy-saving recommendations and
programs.
• Approximately 82% of treatment group respondents recalled receiving a Home Energy
Report from Idaho Power.
• Nearly 76% of treatment group respondents that recalled receiving a Home Energy
Report read all or most of them with 21% reading some of them.
• Over 92% of respondents that read their Home Energy Report agreed that the
information presented in their report was easy to understand.
• Nearly 71% of respondents that read their Home Energy Report agreed that the
recommendations and tips on how to conserve were helpful.
A copy of the survey results is included in Supplement 2: Evaluation.
Evaluations
In 2020, Idaho Power contracted a third-party evaluator to conduct a process evaluation for the
HER Program alongside the Educational Distributions program evaluation. However, due to
some late findings, additional analysis was required to complete the evaluation. The evaluation
report for the HER Program was completed in April 2021 and each of the recommendations are
addressed in the section above. See the Program Activity section above for specific
recommendations and company responses. See Supplement 2: Evaluation for the
complete report. The company plans to conduct an impact evaluation in 2022, and this
evaluation may help inform the company about any needed changes to the program.
2022 Program and Marketing Strategies
Idaho Power plans to continue to deliver Home Energy Reports to active program participants
on a quarterly schedule with reports arriving in February, May, August, and November.
Participants with high A/C use or winter heating will also receive seasonal reports in either May
or November, as appropriate. Idaho Power will also evaluate the possibility of segmenting
HER participants to provide energy-saving tips related specifically to those with electric
water heaters.
Idaho Power is currently upgrading the HER Program software platform which should provide
opportunities to enhance the Home Energy Report template and/or messaging. As new options
become available, the company will actively assess them with an effort toward improving
savings and enhancing the customer experience.

products in multifamily dwellings with electrically heated water in Idaho and Oregon. These
energy-saving products are installed by an insured contractor hired by Idaho Power at no cost
to the property owner, manager, or tenant. Idaho Power defines a multifamily dwelling as a
building consisting of five or more rental units. The products installed are: ENERGY STAR® LED
lightbulbs, high-efficiency thermostatic shower valve (TSV) showerheads, kitchen and bathroom
faucet aerators, and water heater pipe insulation.
To ensure energy savings and eligibility, Idaho Power pre-approves each building and the
contractor who will install the energy efficiency measures. Upon approval, the no-cost,
direct installation is scheduled, and a tailored door hanger is placed on tenants’ apartments to
explain the schedule and process of the installation.
Program Activities
Due to COVID-19 contractor restrictions, and for customer and contractor safety, in-home work
remained suspended through November 2021. This resulted in no units being completed and
no energy savings claimed in 2021.
In 2021, the company identified a small number of apartment complex owners/managers
interested in participating in the program. These customers were placed on a waitlist and
Residential Sector—Multifamily Energy Savings Program
Demand-Side Management 2021 Annual Report Page 73
notified they would be contacted once in-home work resumed. Program contractors began
contacting those on the waitlist in December 2021 and will continue to do so into 2022.
Marketing Activities
Idaho Power continued to run three alternating, clickable ads on its Landlord/Property Manager
Requests web page that linked users to the Multifamily Energy Savings Program web page.
A marketing video placed at the top of the Multifamily Energy Savings Program web page also
continued to run in 2021. The video explains the eligibility requirements, the no-cost
direct-install measures available to landlords/tenants, the installation process, and the
potential for residents to save on their monthly bills and to be more comfortable in their
homes. At the end of the video, company contact information is provided.
In January, Idaho Power placed a print ad promoting the program in the Idaho Business
Review’s special Multifamily Residential section. The ad featured updated imagery to match the
refreshed look of the company’s energy efficiency marketing collateral.
Cost-Effectiveness
The program’s cost-effectiveness was impacted by the suspension of in-home visits due to
COVID-19.
Due to the reduction of savings for the deemed measure options, cost-effectiveness for the
program in its current format will be a challenge on an ongoing basis. Previously, the RTF was
the source of savings for many of the measures in the program. In 2020, the LED lightbulbs had
a deemed savings value of 16.17 to 83.87 kWh per year depending on the type and lumens of
the lightbulbs and the location of the lightbulb installation. Based on the RTF version 9.4
lighting workbook, these savings now range between 4.73 to 13.81 kWh. To improve the
accuracy of the data being collected, Idaho Power modified the installation worksheets,
which will help Idaho Power calculate the lighting savings for each install based on information
around the existing lamp and the location of the installation rather than using a deemed savings
value from the RTF. However, there are still challenges related to the other direct-install items.
In 2020, the RTF reviewed the savings associated with low-flow showerheads. Because of the
uncertainty around the relationship between the hot water savings and the low-flow
showerhead and the increasing efficiency for showerheads in the region due to codes and
standards, the RTF deactivated the low-flow showerhead measure. Although Idaho Power
installs a different showerhead (the integrated 1.75 gallons per minute [gpm] showerhead with
the TSV), the RTF workbook was updated to remove the savings associated with the
showerhead. The savings for the integrated showerhead with TSV is now solely based on the
TSV itself, resulting in a reduction in annual savings from 198 kWh to 50 kWh. Additionally, the
RTF reviewed aerator savings in 2021. Like the showerheads, there was uncertainty with the
Residential Sector—Multifamily Energy Savings Program
Page 74 Demand-Side Management 2021 Annual Report
savings associated with aerators and the RTF deactivated the measure. There will be no savings
associated with the aerators in 2022.
Idaho Power has shared these challenges with EEAG and plans to convene a subcommittee in
2022 to discuss the savings assumptions around the program and alternatives to the current
direct-install retrofit model. The company will continue to work with EEAG to determine the
program’s future and ways the company can still serve this population of customers.
2022 Program and Marketing Strategies
Because COVID-19 restrictions were lifted as of December 2021, interested owners/managers
will be contacted by both the program manager and installation contractors to revisit the
program in those buildings. Residential energy advisors will also be looking for potential
projects in their areas.
Idaho Power will resume pursuing energy-efficient direct-installation projects in multifamily
dwellings throughout its service area. The company will continue to use informative
notifications, pre-installation door hangers, and post-installation informational marketing
pieces, as well as survey cards for scheduled projects. The company will also advertise in
industry publications to encourage property owner/manager engagement and to increase
program visibility.

Description
Idaho Power offers free energy audits for electrically heated customer homes within the
Oregon service area. This is a program required by Oregon Revised Statute (ORS) 469.633 and
has been offered under Oregon Tariff Schedule 78 since 1980. Upon request, an energy audit
contractor hired by Idaho Power visits the customer’s home to perform a basic energy audit
and to analyze it for energy efficiency opportunities. An estimate of costs and savings for
recommended energy-efficient measures is given to the customer. Customers may choose
either a cash incentive or a 6.5%-interest loan for a portion of the costs for weatherization
measures.
Program Activities
Due to COVID-19 restrictions, and for customer and contractor safety, in-home activity
remained suspended through late December 2021, which resulted in no program participation.
The nine customers who expressed program interest, seven in 2020 and two in 2021,
were contacted by an energy advisor to notify them of in-home activity suspension and to
confirm program eligibility. The energy advisor informed qualified customers they would be
contacted by the contracted energy auditor when the program was reinstated.
Residential Sector—Oregon Residential Weatherization
Page 76 Demand-Side Management 2021 Annual Report
Marketing Activities
In October, Idaho Power sent 10,361 Oregon residential customers an informational brochure
about energy audits and home weatherization financing.
Cost-Effectiveness
The Oregon Residential Weatherization program is a statutory program described in Oregon
Schedule 78, which includes a cost-effectiveness definition of this program. Pages three and
four of Schedule 78 identify the measures determined to be cost-effective and the specified
measure life cycles for each. This schedule also includes the cost-effective limit (CEL) for
measure lives of seven, 15, 25, and 30 years.
2022 Program and Marketing Strategies
In-home work resumed as of late 2021, and eligible customers on the waiting list will be
contacted. Due to staffing shortages in late 2021, the contractor will begin contacting
interested customers to schedule in-home audits in January of 2022. Idaho Power will continue
to market the program to customers with a bill insert/brochure.

Description
Initiated in 2003, the Rebate Advantage program helps Idaho Power customers in Idaho and
Oregon with the initial costs associated with purchasing new, energy-efficient, ENERGY STAR®
qualified manufactured homes. This enables the homebuyer to enjoy the long-term benefit of
lower electric bills and greater comfort. The program also provides an incentive to the sales
consultants to encourage more sales of ENERGY STAR® qualified homes and more discussion of
energy efficiency with their customers during the sales process.
In addition to offering financial incentives, the Rebate Advantage program educates
manufactured home buyers and retailers about the benefits of owning energy-efficient models.
The Northwest Energy-Efficient Manufactured Home Program™ (NEEM), a consortium of
manufacturers and state energy offices in the Northwest, establishes quality control (QC) and
energy efficiency specifications for qualified manufactured homes and tracks their production
and on-site performance. NEEM adds the classification Eco-Rated™ for homes produced by
factories that have demonstrated a strong commitment to minimizing environmental impacts
from the construction process.
In 2019, NEEM created the most stringent manufactured home energy standard in the country,
the ENERGY STAR® with NEEM 2.0 specification, which was later renamed the ENERGY STAR®
Residential Sector—Rebate Advantage
Page 78 Demand-Side Management 2021 Annual Report
with NEEM+ certification. NEEM+ standards are engineered to save approximately 30% more
energy than ENERGY STAR® standards. As a result, NEEM+ delivers the highest possible energy
savings and the highest level of overall comfort. These homes are built to specifications tailored
to the Northwest climate.
Program Activities
In 2021, for each home sold under this program, the residential customer incentive was $1,000
and the sales staff incentive was $200. Idaho Power paid 88 incentives on new manufactured
homes, which accounted for 235,004 annual kWh savings. This included 84 homes sited in
Idaho and four sited in Oregon. Of the 88 homes in the program, 13 were NEEM+, 72 were
ENERGY STAR, and three were Eco-Rated.
Marketing Activities
Idaho Power continued to support manufactured home dealerships by providing them with
updated program marketing collateral.
In May and November, Idaho Power promoted the Rebate Advantage program with a bill insert
sent to 302,353 and 296,992 customers, respectively. The insert had information about the
potential energy and cost savings and referred customers to the program website.
In July, the company ran programmatic display ads that garnered 727,595 impressions and
903 clicks through to the website.
Cost-Effectiveness
In May 2020, the RTF updated savings for new construction manufactured homes. First, the RTF
removed the savings designation for Eco-Rated™ certified homes. The energy savings associated
with these homes are the same as those built to ENERGY STAR standards; therefore, the RTF
voted to combine the savings for Eco-Rated and ENERGY STAR manufactured homes. Second,
the RTF removed the assumptions related to non-energy benefits (NEB). The previous
assumptions were based on the reduction of supplemental fuel use, which they found no
evidence of occurring. Finally, when other assumptions around heating system type, lighting,
and other appliances were updated, the average annual savings per home declined by 10%.
Idaho Power used RTF workbook version 4.2 in 2021.
The UCT and TRC for the program are 1.13 and 0.66, respectively.
For detailed information for all measures within the Rebate Advantage program,

2022 Program and Marketing Strategies
Idaho Power plans to address the cost-effectiveness of adding an incentive tier for the ENERGY
STAR with NEEM+ certification homes and review the idea with EEAG. If cost effective,
Idaho Power believes this could help promote the sales of these higher efficiency homes.
Idaho Power will continue to support manufactured home dealers by providing them with
program materials. The company will also distribute a bill insert to Idaho and Oregon
customers and explore digital advertising to promote the program to potential manufactured
home buyers.

Description
The Residential New Construction Program launched in March 2018 as a pilot, replacing the
ENERGY STAR® Homes Northwest Program, and transitioned to a regular program in 2021.
The Residential New Construction Program offers builders a cash incentive to build
energy-efficient, single-family, all-electric homes that use heat pump technology in Idaho
Power’s Idaho service area. These homes must meet strict requirements that make them 10%,
15%, or 20% more energy efficient than homes built to standard state energy code.
The RTF and NEEA have created specific modeling requirements and program guidelines to
ensure the program provides reliable energy savings for utilities across the northwest.
These homes feature high performance HVAC systems, high-efficiency windows,
increased insulation values, and tighter building shells to improve comfort and save energy.
Idaho Power claims energy savings based on each home’s individual modeled savings.
Builders must contract with a Residential Energy Services Network (RESNET)-certified rater to
ensure the home design will meet program qualifications. The rater will work with the builder
from the design stages through project completion; perform the required energy modeling
(REM) using REM/Rate modeling software; perform site inspections and tests; and enter,
maintain, and submit all required technical documentation in the REM/Rate modeling software
and the NEEA-maintained AXIS database. This data is used to determine the energy savings and
the percent above code information needed to certify the home.
Residential Sector—Residential New Construction Program
Demand-Side Management 2021 Annual Report Page 81
Program Activities
Participating residential builders who built homes at least 10% above the standard state energy
code, as determined by the REM/Rate energy modeling software and AXIS database output,
were incentivized as follows:
• 10 to 14.99% above code: $1,200 incentive
• 15 to 19.99% above code: $1,500 incentive
• 20% or more above code: $2,000 incentive
In 2021, the company paid incentives for 90 newly constructed energy-efficient homes in Idaho,
and the homes accounted for 389,748 kWh of energy savings.
On January 1, 2021, the Idaho energy code increased from the 2012 IECC up to the 2018 IECC
(with state-specific amendments). This increase makes it more difficult for builders to achieve
the program’s incentive tier levels.
To align with the new Idaho state energy code and updates to the regional Performance Path
programs prescribed by the RTF, Idaho Power’s Residential New Construction Program
implemented the following updates:
• August 8, 2021 was the last day for raters to submit homes in AXIS to be certified under
alignment with the previous state energy code and the Idaho Power Utility Incentive,
V2 program.
• August 9, 2021 was the first day for raters to submit homes in AXIS to be certified in
alignment with the new/current energy code and the updated Idaho Power Utility
Incentive, V3 Program.
Early in 2021, NEEA removed their support on the region’s residential new construction
programs due to some markets in the Northwest being determined to be transformed. NEEA
program support included both file and field QA as well as new rater training/on-boarding and
current rater technical problems. On May 24, 2021, Idaho Power signed a contract with
Washington State University Energy Program to perform both file and field QA services on
home energy ratings performed by the program raters. The university’s contract also includes
new rater training/on-boarding as well as working with current rater technical problems/issues.
Marketing Activities
Due to COVID-19 restrictions, the company was unable to participate in in-person Building
Contractors Association (BCA) events, including the Idaho (IBCA) Winter Board Meeting,
the IBCA Fall Board Meeting, and regional BCA Builders’ Expos as has been done consistently in
past years.
Residential Sector—Residential New Construction Program
Page 82 Demand-Side Management 2021 Annual Report
Idaho Power supported 2021 Parade of Homes events with full-page ads in the Parade of
Homes magazines of the following BCAs: The Magic Valley Builders Association (MVBA),
the Building Contractors Association of Southwestern Idaho (BCASWI), the Snake River Valley
Building Contractors Association (SRVBCA), and the Building Contractors Association of
Southeast Idaho (BCASEI). A print ad appeared in the March issue of Boise Lifestyle and
Meridian Lifestyle magazines that highlighted top home builders and residential real estate.
A digital app ad and company listing was also included as part of the advertising package with
the MVBA.
The program brochure was included as part of a direct-mail package sent to 524 contractors in
July and November touting the benefits of all-electric construction. The brochure was also left
at the City of Boise permitting office as a hard copy handout.
The company sent a bill insert to 302,353 Idaho customers in May to promote the program.
The program was featured in the August edition of Connections, Idaho Power’s monthly
newsletter for customers; the article highlighted NeighborWorks Boise® and their successful
participation in the program.
A Certificate of Completion that brands homes certified within the program as, “Certified Idaho
Power Efficient Homes” was created in 2021 and is being sent to builders with their incentive
checks. The brand gives builders a name for the energy efficient product they are building, and
the certificate is a piece they can leave with the homeowner to show they have purchased a
well-built, efficient home.
A sticker using the same “Certified Idaho Power Efficient Home” branding was also developed
to use as a leave-behind at homes that participated in the program. The sticker is an easily
removable decal and allows the rater to easily write in the home percentage above state code
and the kWh savings. It’s meant to be left on the HVAC system—similar to stickers HVAC
companies leave behind.

Cost-Effectiveness
The savings for the 90 energy-modeled homes average approximately 4,331 kWh per home
depending on which efficiency upgrades were included, an increase over the average energy-
modeled savings of 2,619 kWh per home in 2020. This increase is largely due to two factors.
First, a larger percentage of the homes built in 2021 (~63%) were built 20% or more above
code, relative to homes built in 2020 (~25%). Second, a larger percentage of the homes built in
2021 (~33%) were detached single-family homes, relative to homes built in 2020 (~13%).
Single-family homes tend to have larger savings when compared to attached townhomes and
condos. Additionally, several large projects with over 10,000 kWh of savings were completed in
2021. If those large homes are excluded, the average energy-modeled savings is approximately
3,674 kWh.
While savings are custom calculated for each of the 90 modeled homes, the incremental costs
over a code-built home are difficult to determine. The RTF’s single-family new construction
workbook was used as a proxy for the incremental costs and NEBs.
Residential Sector—Residential New Construction Program

The UCT and TRC ratios for the program are 1.64 and 0.99, respectively.
For more detailed information about the cost-effectiveness savings and assumptions,

2022 Program and Marketing Strategies
Idaho Power plans to continue to promote this program to Idaho builders and new home
buyers. These marketing efforts include ads in Parade of Homes magazines for the BCASWI,
SRVBCA, MVBA, and the BCASEI. A bill insert is planned for spring 2022. The company also plans
to continue supporting the general events and activities of the IBCA and its local affiliates.
Social media and other advertising will be considered based on past effectiveness.

Description
Idaho Power’s Shade Tree Project operates in a small geographic area each spring and fall,
offering no-cost shade trees to Idaho residential customers. Participants enroll using the online
Energy-Saving Trees tool and pick up their tree at specific events. Unclaimed trees are donated
to cities, schools, and other non-profit organizations.
Using the online enrollment tool, participants locate their home on a map, select from a list of
available trees, and evaluate the potential energy savings associated with planting in different
locations. During enrollment, participants learn how trees planted to the west and east save
more energy over time than trees planted to the south and north.
Ensuring the tree is planted properly helps it grow to provide maximum energy savings. At the
tree pick-up events, participants receive additional education on where to plant trees for
maximum energy savings and other tree care guidance from local experts. These local
specialists include city arborists from participating municipalities, Idaho Power utility arborists,
county master gardeners, and College of Southern Idaho (CSI) horticulture students.
Each fall, Idaho Power sends participants from the previous two offerings a newsletter filled
with reminders on proper tree care and links to resources, such as tree care classes and
educational opportunities in the region. This newsletter was developed after the 2015 field
audits identified common customer tree care questions and concerns.
Residential Sector—Shade Tree Project
Page 86 Demand-Side Management 2021 Annual Report
According to the DOE, a well-placed shade tree can reduce energy used for summer cooling by
15% or more. Utility programs throughout the country report high customer satisfaction with
shade tree programs and an enhanced public image for the utility related to sustainability and
environmental stewardship. Other utilities report energy savings between 40 kWh per year
(coastal climate, San Diego) and over 200 kWh per year (Phoenix) per tree planted.
To be successful, trees should be planted to maximize energy savings and ensure survivability.
Two technological developments in urban forestry—the state sponsored Treasure Valley Urban
Tree Canopy Assessment and the Arbor Day Foundation’s Energy-Saving Trees tool—provide
Idaho Power with the information to facilitate a shade tree project.
Program Activities
Due to COVID-19 restrictions and to ensure the safety of customers, employees, and
volunteers, the decision was made to partner with the Arbor Day Foundation for the 2021
events and have the trees shipped directly to customer homes rather than holding in-person
pick-up events. Shipped delivery was used for both the spring and fall events. The spring event
was made available to residential customers that reside in the Treasure Valley while the fall
event was offered to customers who live in the Magic Valley, and later opened to customers in
the Wood River Valley. The trees came from a grower selected by the Arbor Day Foundation.
Both events had 1,500 trees available. Due to the mail delivery method and added shipping
fees, the trees available in 2021 were one-gallon trees, as opposed to the three- to five-gallon
trees that were distributed through the traditional in-person events. The smaller trees resulted
in some decreased customer satisfaction. In 2019, 93% of respondents strongly agreed they
were satisfied with their overall experience with the program, while only 66% of respondents
who participated in the 2021 offering strongly agreed they were satisfied with their overall
experience in the program.

Idaho Power continues to track the program data in the DSM database. The database is also
used to screen applicants during enrollment to determine whether participants meet the
eligibility requirements for the project, such as residential status within the eligible counties.
Participation in the program remains two trees per address for the life of the program.
Marketing Activities
Due to the cancellation of the 2020 Shade Tree events, Idaho Power had compiled a large list of
customers who had submitted their information to be notified of the next Shade Tree offering
in their area. Customers on this list were notified for both the spring and fall events (Figure 18).

Figure 18. Shade Tree Project email to Wood River Valley and Magic Valley residents
Due to slow enrollments during the fall campaign, two additional emails were sent to Magic
Valley and Wood River Valley customers who had homes 20 years old or newer. In addition to a
boosted Facebook post informing Wood River and Magic Valley customers of the open program
enrollment (Figure 19), a News Briefs was also sent to regional news outlets to spread the word
about the available trees.
Residential Sector—Shade Tree Project
Demand-Side Management 2021 Annual Report Page 89

Figure 19. Boosted Facebook post about Shade Tree Project’s fall enrollment
Since in-person events were cancelled and participants could not speak with a tree expert to
learn how to properly plant and maintain their trees, emails were sent to customers with tree
maintenance tips and a copy of a Tree Planting Guide. For the spring event, an email was sent
once the trees were shipped with planting instructions as well as a follow-up email that was
sent a few weeks letter with tips on how to maintain their new trees. For the fall event, the
Arbor Day Foundation sent out the initial “how to plant your tree” email and Idaho Power sent
a follow-up email on how to take care of the trees.
Cost-Effectiveness
For the Shade Tree Project, Idaho Power utilizes the Arbor Day Foundation’s software, which
calculates energy savings and other non-energy impacts based on tree species and
orientation/distance from the home. This software tool, i-Tree, estimates these benefits for
years 5, 10, 15, and 20 after the tree planting year. However, the savings estimates assume
each tree is planted as planned and does not consider survivorship. Idaho Power contracted
with a third party to develop a model to calculate average values per tree using the tool data
and calculated a realization rate based on the survival rate. Unlike traditional energy savings
measures in which the annual savings remain flat throughout the measure life and only first-
year savings are reported, the savings for trees grow as the tree grows when using the
Residential Sector—Shade Tree Project
Page 90 Demand-Side Management 2021 Annual Report
realization rate based on survival. The calculator was used to estimate the 44,173 kWh of
incremental claimable savings in 2021 for the trees planted between 2013 and 2017.
The cost-effectiveness for the program is based on the modeled savings for the trees
distributed in 2021 and costs incurred during 2021. Because the trees were delivered through
the mail, it is estimated the trees are approximately one year younger than the trees
distributed at the in-person events, which the calculator was based on. To adjust for this,
the year the company could begin claiming savings was pushed out a year, thus trees
distributed in 2021 will begin saving 43,086 kWh in 2026. The cost-effectiveness calculations
also include a net-to-gross (NTG) factor of 124%, which accounts for the spillover associated
with the trees shading a neighboring home as well as various non-energy impacts related to the
improved air quality, avoided stormwater runoff, and winter heating detriment. Finally, the
cost-effectiveness calculations were updated to extend the program life from 30 to 40 years.
While the i-Tree software only estimates savings out to 20 years, the contractor worked closely
with the creators of the software to produce saving estimates out to 99 years. The contractor
recommended that Idaho Power use a 40-year measure life. It is estimated that these trees will
save 126,684 kWh in 2061. Based on the model, the project has a UCT of 1.07 and a TRC ratio
of 1.21.
For more detailed information about the cost-effectiveness savings and assumptions,
see Supplement 1: Cost-Effectiveness.
Customer Satisfaction
After each offering, a survey was emailed to participants. The survey asked questions related to
the program marketing, tree-planting education, and participation experience with the
enrollment and tree delivery processes. Results are compared, offering to offering, to look for
trends to ensure the program processes are still working to identify opportunities for
improvement. Because this was Idaho Power’s first year shipping the trees directly to
customers, Idaho Power is also comparing customer satisfaction results from participants who
picked up trees at in-person events in the past. Data is also collected about where and when
the participant planted the tree. This data will be used by Idaho Power to refine energy-saving
estimates.
In total, the survey was sent to 1,568 Shade Tree Project participants and received 570
responses for a response rate of 36%. Participants were asked how much they would agree or
disagree that they would recommend the project to a friend. Nearly 76% of respondents said
they “strongly agree,” and nearly 13% said they “somewhat agree.” Participants were asked
how much they would agree or disagree that they were satisfied with the overall experience
with the Shade Tree Project. Nearly 66% of respondents indicated they “strongly agree,” and
Residential Sector—Shade Tree Project
Demand-Side Management 2021 Annual Report Page 91
over 21% “somewhat agree” they were satisfied. View the complete survey results in
Supplement 2: Evaluation.
2022 Program and Marketing Strategies
Idaho Power plans to continue the Shade Tree Project in 2022, with the spring offering to
customers in the Treasure Valley and the fall event to customers in the Magic Valley.
The enrollment process will remain the same, using the Arbor Day Foundation enrollment tool.
For customers who don’t feel comfortable or able to attend an in-person pick-up event,
the company will partner with the Arbor Day Foundation to deliver one-gallon trees to their
homes. Additionally, in-person events will resume where three- to five-gallon trees will be
available for customer pick up. Safety protocols will be in place to ensure these events do not
contribute to the spread of COVID-19.
Idaho Power will continue to market the program through direct-mail, focusing on customers
identified as living in newly constructed homes and those identified using the Urban Tree
Canopy Assessment tool in the Treasure Valley. The program will be promoted in the April 2022
Home Energy Report. In addition, Idaho Power maintains a wait list of customers who were
unable to enroll because previous offerings were full. Idaho Power will reach out to these
customers through email for the 2022 offerings. Idaho Power will continue to leverage allied
interest groups and use social media and boosted Facebook posts if enrollment response
rates decline.

Description
The WAQC program provides financial assistance to regional CAP agencies in Idaho Power’s
service area. This assistance helps fund weatherization costs of electrically heated homes
occupied by qualified customers who have limited incomes. Weatherization improvements
enable residents to maintain a more comfortable, safe, and energy-efficient home while
reducing their monthly electricity consumption and are available at no cost to qualified
customers who own or rent their homes. These customers also receive educational materials
and ideas on using energy wisely in their homes. Local CAP agencies determine participant
eligibility according to federal and state guidelines. The WAQC program also provides limited
funds to weatherize buildings occupied by non-profit organizations that serve primarily
special-needs populations, regardless of heating source, with priority given to electrically
heated buildings.
In 1989, Idaho Power began offering weatherization assistance in conjunction with the State of
Idaho Weatherization Assistance Program (WAP). In Oregon, Idaho Power offers weatherization
assistance in conjunction with the State of Oregon WAP. This allows CAP agencies to combine
Idaho Power funds with federal weatherization funds to serve more customers with special
needs in electrically heated homes.
Idaho Power has an agreement with each CAP agency in its service area for the WAQC program
that specifies the funding allotment, billing requirements, and program guidelines. Currently,
Residential Sector—Weatherization Assistance for Qualified Customers
Demand-Side Management 2021 Annual Report Page 93
Idaho Power oversees the program in Idaho through five regional CAP agencies: Eastern Idaho
Community Action Partnership (EICAP), El Ada Community Action Partnership (EL ADA),
Metro Community Services (Metro Community), South Central Community Action Partnership
(SCCAP), and Southeastern Idaho Community Action Agency (SEICAA). In Oregon,
Community Connection of Northeast Oregon, Inc. (CCNO), and Community in Action (CINA)
provide weatherization services for qualified customers.
The Idaho Department of Health and Welfare (IDHW) uses the DOE-approved energy audit
program (EA5) for the Idaho WAP and, therefore, the Idaho CAP agencies use the EA5.
Annually, Idaho Power verifies a portion of the homes weatherized under the WAQC program.
This is done through two methods. The first method uses Idaho’s and Oregon’s state
monitoring processes for weatherized homes. The state hires the quality-control inspector,
who ensures measures were installed to DOE and state WAP specifications.
Utility representatives, weatherization personnel from the CAP agencies, CAPAI, and a Building
Performance Institute (BPI)-certified QC inspector review homes weatherized by each of the
CAP agencies.
For the second method, Idaho Power contracts with two companies that employ building
performance specialists to verify the installed measures. After verification, any required
follow-up is done by CAP agency personnel.
Idaho Power reports the activities related to the WAQC program as set forth below in
compliance with IPUC Order No. 29505, as updated in Case No. IPC-E-16-30, Order No. 33702
and consolidates the WAQC Annual Report with Idaho Power’s Demand-Side Management
Annual Report each year.
Program Activities
Weatherized Homes and Non-Profit Buildings by County
In 2021, Idaho Power made $1,861,402 available to Idaho CAP agencies. Of the funds provided,
$990,416 were paid to Idaho CAP agencies, while $870,985 were accrued for future funding.
This relatively large carryover was caused by COVID-19 in-home activity restrictions,
supply chain limitations, and labor shortages limiting the number of homes CAP agencies
weatherized. Of the funds paid in 2021, $900,379 directly funded audits, energy efficiency
measures, and health and safety measures for qualified customers’ homes (production costs)
in Idaho, and $90,038 funded administration costs to Idaho CAP agencies for those
homes weatherized.
In 2021, Idaho Power funds provided for the weatherization of 161 homes in Idaho, one in
Oregon, and no non-profit buildings in Idaho. Table 12 shows each CAP agency, the number of
homes weatherized, production costs, the average cost per home, administration payments,
and total payments per county made by Idaho Power.

The base funding for Idaho CAP agencies is $1,212,534 annually, which does not include
carryover from the previous year. Idaho Power’s agreements with CAP agencies include a
provision that identifies a maximum annual average cost per home up to a dollar amount
specified in the agreement between each CAP agency and Idaho Power. The intent of the
maximum annual average cost allows the CAP agency flexibility to service some homes with
greater or fewer weatherization needs. It also provides a monitoring tool for Idaho Power to
forecast year-end outcomes. The average cost per home weatherized is calculated by dividing
the total annual Idaho Power production cost of homes weatherized by the total number of
homes weatherized that the CAP agencies billed to Idaho Power during the year. The maximum
annual average cost per home in the 2021 agreement was $6,000. In 2021, Idaho CAP agencies
had a combined average cost per home weatherized of $5,592.
CAP agency administration fees are equal to 10% of Idaho Power’s per-job production costs.
The average administration cost paid to agencies per Idaho home weatherized in 2021 was
$559. Not included in this report’s tables are additional Idaho Power staff labor, marketing,
and support costs for the WAQC program totaling just over $69,400 for 2021. These expenses
were in addition to the WAQC program funding requirements in Idaho specified in IPUC Order
No. 29505.
In compliance with IPUC Order No. 29505, WAQC program funds are tracked separately,
with unspent funds carried over and made available to Idaho CAP agencies in the following
year. In 2021, $648,868 in unspent funds from 2020 were made available for expenditures in
Idaho. Table 13 details the funding base and available funds from 2020, and the total amount of
2021 spending.

To help keep weatherization crews and customers safe from exposure to COVID-19, CAP
agencies suspended weatherization activities for Idaho Power’s WAQC program in March 2020,
and most resumed work starting in May 2020. In 2021, Idaho Power allowed CAP agencies to
leverage funding of their state WAP jobs with Idaho Power funds. However, home verification
contractors continued the temporary suspension from 2020 and no verifications were made to
customer homes through Idaho Power’s two home verifiers in 2021.
The DOE also had CAP agency Weatherization follow Centers for Disease Control and
Prevention (CDC) and DOE COVID-19 guidelines. Various CAP agencies performed certain
weatherization activities under CDC and DOE guidelines throughout 2021. Because
weatherization personnel provided services for the state WAPs between March and December,
Idaho Power allowed CAP agencies within its service area to leverage state and federal funding
along with its funding.
Because of COVID-19 restrictions, supply chain issues, and labor shortages,
various weatherization department’s production schedules were lower than normal, and less
Idaho Power funding was spent in 2021. Unspent funding will be carried over to 2022.
Weatherization Measures Installed
Table 14 details home counts for which Idaho Power paid all or a portion of each measure’s
cost during 2021. The home counts column shows the number of times any percentage of that
measure was billed to Idaho Power during the year. If totaled, measure counts would be higher
than total homes weatherized because the number of measures installed in each home varies.
WAQC and other state WAPs nationwide are whole-house programs that offer several
measures that have costs but do not necessarily save energy, or for which the savings cannot
be measured. Included in this category are health and safety measures and home energy
audits. Health and safety measures are necessary to ensure weatherization activities do not
cause unsafe situations in a customer’s home or compromise a home’s existing indoor air
quality (IAQ). Idaho Power contributes funding for the installation of items that do not save
energy, such as smoke and carbon monoxide detectors, vapor barriers, electric panel upgrades,
floor registers and boots, kitchen range fans, and venting of bath and laundry areas.
While these items increase health, safety, and comfort and are required for certain
energy-saving measures to work properly, they increase costs of the job.

Marketing Activities
Information about WAQC is available in a brochure (English and Spanish) and on the Income
Qualified Customers page of Idaho Power’s website. The CAP agencies promote the program
and maintain a continual waiting list for interested customers.
Cost-Effectiveness
In 2021, WAQC program cost-effectiveness was 0.19 from the UCT perspective and 0.31 from
the TRC perspective.
While final cost-effectiveness is calculated based on measured consumption data,
cost-effectiveness screening begins during the initial contacts between CAP agency
weatherization staff and the customer. In customer homes, the agency weatherization auditor
uses the EA5 to conduct the initial audit of the home. The EA5 compares the efficiency of the
Residential Sector—Weatherization Assistance for Qualified Customers
Page 98 Demand-Side Management 2021 Annual Report
home prior to weatherization to the efficiency after the proposed improvements and calculates
the value of the efficiency change into a savings-to-investment ratio (SIR). The output of the SIR
is similar to the PCT ratio. If the EA5 computes an SIR of 1.0 or higher, the CAP agency is
authorized to complete the proposed measures. The weatherization manager can split
individual measure costs between Idaho Power and other funding sources with a maximum
charge of 85% of total production costs to Idaho Power. Using the audit tool to pre-screen
projects ensures each weatherization project will result in energy savings.
The 2021 cost-effectiveness analysis continues to incorporate the following directives from
IPUC Order No. 32788:
• Applying a 100% NTG value to reflect the likelihood that WAQC weatherization projects
would not be initiated without the presence of a program
• Claiming 100% of project savings
• Including an allocated portion of the indirect overhead costs
• Applying the 10% conservation preference adder
• Claiming $1 of benefits for each dollar invested in health, safety, and repair measures
• Amortizing evaluation expenses over a three-year period
Finally, the cost-effectiveness calculations were updated in 2021 to remove the impacts of any
accruals and reversals associated with unspent dollars carried over into the following year.
Generally, the carryover dollars are reversed the following year when the CAP agencies spend
the previous year’s unused funds. A new accrual is made at the end of the year for the new
carryover dollars. By leaving the carryover accounting entry in the cost-effectiveness
calculation, it would overstate expenses in 2021 while the subsequent reversal would
understate expenses in 2022.
Idaho Power will continue to work with EEAG, as well as the weatherization managers who
oversee the weatherization work, to discuss ways to improve the program. For further details
on the overall program cost-effectiveness assumptions, see Supplement 1: Cost-Effectiveness.
Customer Education and Satisfaction
The CAP agency weatherization auditor explains to the customer which measures are analyzed
and why. Further education is done as the crew demonstrates the upgrades and how they will
help save energy and provide an increase in comfort. Idaho Power provides each CAP agency
with energy efficiency educational materials for distribution to customers during home visits.
Any customers whose homes are selected for the company’s post-weatherization home
verification receive additional information from home verifiers and have an opportunity to ask
follow-up questions.
Residential Sector—Weatherization Assistance for Qualified Customers
Demand-Side Management 2021 Annual Report Page 99
Idaho Power uses independent, third-party verification companies to ensure the stated
measures were installed in the homes and to discuss the program with these customers.
In 2021, home verifiers did not visit customer homes for feedback about the program due to
COVID-19 concerns and the temporary suspension of in-home visits.
A customer survey was used to assess major indicators of customer satisfaction throughout the
service area. All program participants in all regions were asked to complete a survey after their
homes were weatherized. Survey questions gathered information about how customers
learned of the program, reasons for participating, how much customers learned about saving
energy in their homes, and the likelihood of household members changing behaviors to use
energy wisely.
Idaho Power received survey results from 124 of 162 households weatherized by the program
in 2021. Some highlights include the following:
• Just over 37% of respondents learned of the program from a friend or relative, and over
18% learned of the program from an agency flyer.
• Over 46% of the respondents reported their primary reason for participating in the
weatherization program was to reduce utility bills, just over 20% had concerns about
their existing furnace, and over 21% wanted to improve the comfort of their home.
• Nearly 22% reported they learned how air leaks affect energy usage, and just over 18%
indicated they learned how insulation affects energy usage during the
weatherization process.
• Over 21% of respondents said they learned how to use energy wisely. Most respondents
(90%) reported they were very likely to change habits to save energy, and almost 85%
reported they have shared all the information about energy use with members of
their household.
• Nearly 94% of the respondents reported they think the weatherization they received
will significantly affect the comfort of their home, and almost all (98%) said they were
very satisfied with the program.
• Over 17% of the respondents reported the habit they were most likely to change was
washing full loads of clothes, and more than 20% said that turning off all the lights when
not in use was a habit they were likely to adopt to save energy. Turning the thermostat
up in the summer was reported by over 17% of the respondents and turning the
thermostat down in the winter was reported by more than 18% as a habit they and
members of the household were most likely to adopt to save energy.
A summary of the survey is included in Supplement 2: Evaluation.

2022 Program and Marketing Strategies
In 2022, Idaho Power will continue to provide financial assistance to CAP agencies while
exploring changes to improve program delivery. The company will also continue to provide the
most benefit possible to special-needs customers while working with Idaho and Oregon WAP
personnel. Since the retirement of the Idaho state WAP energy audit tool (EA5) is planned for
2022, CAP agency personnel will invoice Idaho Power with a new job cost calculator.
Idaho Power plans to verify approximately 5% of the homes weatherized under the WAQC
program via home-verification companies and the Idaho and Oregon state monitoring process.
In 2022, Idaho Power will support the whole-house philosophy of the WAQC program and
Idaho and Oregon WAP by continuing to allow a $6,000 annual maximum average per-home
cost. The company will continue to work with CAPAI, CAP agencies, and IDHW to develop
recommendations and ideas to help improve the program for customers with special needs.
In Idaho during 2022, Idaho Power expects to contribute the base amount plus available funds
from 2021 to total just over $2,083,500 in weatherization measures and agency administration
fees. Of this amount, approximately $179,400 will be provided to the non-profit pooled fund to
weatherize buildings housing non-profit agencies that primarily serve qualified customers in
Idaho, with an allowance for annual unused non-profit funds to be used toward additional
residential weatherization projects.
Idaho Power will continue to maintain the program content on its website and other
marketing collateral.

Description
Weatherization Solutions for Eligible Customers is an energy efficiency program designed to
serve Idaho Power residential customers in Idaho whose income falls between 175% and 250%
of the current federal poverty level. Initiated in 2008, the program is designed to mirror the
WAQC program. These customers often do not have disposable income to invest in energy
efficiency upgrades, and they typically live in housing similar to WAQC customers.
The Weatherization Solutions program also benefits certain customers on the WAQC waiting
list. When customer income overlaps both programs, this program may offer an earlier
weatherization date than WAQC, resulting in less wait time for the customer and quicker
energy savings.
Potential participants are interviewed by a participating contractor to determine household
occupant income eligibility, as well as to confirm the home is electrically heated. If the home is
a rental, the landlord must agree to maintain the unit’s current rent for a minimum of one year,
and to help fund a portion of the cost of weatherization. If the customer is eligible, an auditor
inspects the home to determine which upgrades will save energy, improve IAQ, and/or provide
health and safety measures for the residents. To be approved, energy efficiency measures and
repairs must have an SIR of 1.0 or higher, interact with an energy-saving measure, or be
necessary for the health and safety of the occupants.
Residential Sector—Weatherization Solutions for Eligible Customers
Page 102 Demand-Side Management 2021 Annual Report
The Weatherization Solutions for Eligible Customers program uses a home audit tool called the
HAT14.1, which is like the EA5 audit tool used in WAQC. The home is audited for energy
efficiency measures, and the auditor proposes upgrades based on the SIR ratio calculated by
HAT14.1. As in WAQC, if the SIR is 1.0 or greater, the contractor is authorized to upgrade that
measure. Measures considered for improvement are window and door replacement; ceiling,
floor, and wall insulation; HVAC repair and replacement; water heater repair and replacement;
and pipe wrap. Also included is the potential to replace lightbulbs and refrigerators.
Contractors invoice Idaho Power for the project costs, and if the home is a rental, a minimum
landlord payment of 10% of the cost is required.
Idaho Power’s agreement with contractors includes a provision that identifies a maximum
annual average cost per home. The intent of the maximum annual average cost is to allow
contractors the flexibility to service homes with greater or fewer weatherization needs. It also
provides a monitoring tool for Idaho Power to forecast year-end outcomes.
Program Activities
Due to COVID-19 restrictions, in-home work was suspended from early 2020 thru mid-October
of 2021. At the time of the 2020 in-home work suspension, seven homes had been audited
and/or weatherization activities had begun. Weatherization activities for those seven homes
were completed once in-home work resumed in late 2021—four in south-central Idaho and
three in the company’s Capital Region (Figure 2). Of those seven homes weatherized, four were
single-family and three were manufactured homes.
Marketing Activities
Due to in-home work being suspended since March 2020, no program marketing was done
in 2021.
In the absence of Weatherization Solutions program offerings, Idaho Power promoted
do-it-yourself winter weatherization techniques with a December bill insert and email to
243,833 residential customers. The insert was sent to 312,161 Idaho and Oregon residential
customers and included tips like checking for air leaks, installing a smart thermostat,
and behavior changes to increase comfort and lower energy bills.

Cost-Effectiveness
In 2021, the Weatherization Solutions for Eligible Customers program cost-effectiveness was
0.15 from the UCT perspective and 0.28 from the TRC perspective.
Weatherization Solutions for Eligible Customers projects, similar to WAQC program guidelines,
benefit from a pre-screening of measures through a home audit process. The home audit
process ensures an adequate number of kWh savings to justify the project and provides more
consistent savings for billing analysis. See WAQC cost-effectiveness for a discussion of the audit
and prescreening process, which is similar for both programs.
For further details on the overall program cost-effectiveness assumptions, see Supplement 1:
Cost-Effectiveness.
Residential Sector—Weatherization Solutions for Eligible Customers
Page 104 Demand-Side Management 2021 Annual Report
Customer Satisfaction
Due to the limited number of projects resulting from COVID-19 restrictions, customer surveys
were not distributed in 2021. Though two independent companies normally perform random
verifications of weatherized homes and visit with customers about the program, no homes
were verified because of COVID-19 restrictions.
2022 Program and Marketing Strategies
On October 25, 2021, once COVID-19 safety protocols allowed for in-home work to resume,
Idaho Power notified contractors to resume weatherization projects. It is anticipated that
program activity may be lower than normal in 2022 due to worker shortages, supply chain
restrictions, and the high volume of WAQC applicants on regional CAP Agency waiting lists.
Idaho Power will update brochures as necessary to help spread the word about the program in
all communities in 2022. If needed, additional marketing for the program may include bill
inserts, emails, News Briefs, website updates, and ads in various regional publications,
particularly those with a senior and/or low-income focus. Social media posts and boosts,
coordinated partner content, and employee education may be used to increase awareness.
Regional marketing and targeted digital ads will be considered based on need as evidenced by
any regional contractor’s waiting list for Weatherization Solutions services.

C&I Sector Overview
Demand-Side Management 2021 Annual Report Page 105
Commercial & Industrial Sector Overview
In 2021, Idaho Power’s commercial and industrial (C&I) sector consisted of 76,022 commercial,
governmental, school, and small business customers. The number of customers increased by
1,613 or 2.2% from 2020. Energy use per month for customers in this sector is not as
homogenous as other customer sectors and can vary by several hundred thousand kWh each
month depending on customer type. In 2021, the commercial sector represented 27% of Idaho
Power’s total retail annual electricity sales.
Industrial and special contract customers are Idaho Power’s largest individual energy
consumers. In 2021, there were 125 customers in this category, representing approximately
22.5% of Idaho Power’s total retail annual electricity sales.
Idaho Power’s C&I sector has many energy-efficiency programs available to commercial,
industrial, governmental, schools, and small business customers. The suite of options can help
businesses of all sizes implement energy efficiency measures.

customers who wish to find ways to save energy and to quantify their savings can obtain a
scoping assessment and detailed assessment through this option.
C&I Energy Efficiency—New Construction. This option offers specific incentives for designing
and building better-than-code energy-efficient features into a new construction, major
renovation, addition, expansion, or change-of-space project.
C&I Energy Efficiency—Retrofits. This option offers specific incentives for simple energy-saving
retrofits to existing equipment or facilities.
Green Motors Initiative (GMI). Under the GMI, service center personnel are trained and
certified to repair and rewind motors to improve reliability and efficiency. If a rewind returns a
motor to its original efficiency, the process is called a “Green Rewind.” By rewinding a motor
under this initiative, customers may save up to 40% of the cost of a new motor.
Commercial Energy-Saving Kits. This program offers free ESKs filled with products and tips to
help small businesses save energy. Three industry-specific versions of the kit are delivered
directly to Idaho Power’s small business customers: office, restaurant, and retail.
Small Business Direct Install (SBDI). Idaho Power launched an SBDI program in November 2019
targeting typically hard-to-reach small business customers. SBDI is implemented by a third-
party contractor that provides turn-key services. Idaho Power pays 100% of the cost to install
eligible measures for customers who use 25,000 kWh annually or less. SBDI is offered to eligible
customers in a strategic geo-targeted approach.
Oregon Commercial Audits. This statutory-required program offers free energy audits,
evaluations, and educational products to Oregon customers to help them achieve energy
savings.
Demand Response Programs
Flex Peak Program. Idaho Power pays an incentive to commercial and industrial customers who
voluntarily help the company reduce summer demand on specific summer weekdays or for
other system needs.

Idaho Power provides PR support to customers who want to publicize the work they have done
to become more energy efficient. Upon request, Idaho Power creates large-format checks used
for media events and/or board meetings. Idaho Power will continue to assist customers with PR
opportunities by creating certificates for display within their buildings and speaking at press
events, if requested.
While these opportunities were limited in 2021 due to the pandemic, Idaho Power did produce
checks and support PR efforts for several companies, including Simplot, Twin Falls County, CLIF
Bar, ON Semiconductor, Idaho Milk Products, the city of Council, Idaho State University, and the
Wendell School District.
The company also released success-story videos on YouTube highlighting how McCain Foods
and Swan Falls High School benefitted from Idaho Power’s energy efficiency programs. The
videos were shared on Idaho Power’s social media channels and highlighted on the Idaho
Power homepage.
Association and Event Sponsorships
Idaho Power’s C&I Energy Efficiency Program typically sponsors a number of associations and
events. In 2021, many of these events were cancelled or held virtually.
C&I Sector Overview
Demand-Side Management 2021 Annual Report Page 109
The company sponsored the BOMA Commercial Real Estate Symposium held virtually
February 18. During the event, the company shared a video from the new construction senior
engineer that included the Idaho Humane Society success-story video. The company also
developed slides with key company facts that rotated on the screen before the event, placed

and article in the event program. The company also participated in BOMA’s virtual Thursday
Conversations video blog in March.
Idaho Power remained a sponsor of the Idaho Business Review’s Top Projects Awards held in
October in Meridian. The company logo was used throughout the event, and company
materials were placed at the tables.
Customer Satisfaction
Idaho Power conducts the Burke Customer Relationship Survey each year. In 2021, on a scale of
zero to 10, small business survey respondents rated Idaho Power 8.18 regarding offering
programs to help customers save energy, and 8.13 related to providing customers with
information on how to save energy and money. Twenty percent of small business respondents
indicated they have participated in at least one Idaho Power energy efficiency program. Of the
small business survey respondents who have participated in at least one Idaho Power energy
efficiency program, 92% are “very” or “somewhat” satisfied with the program.
In 2021, on a scale of zero to ten, large commercial and industrial survey respondents rated
Idaho Power 9.16 regarding offering programs to help customers save energy, and 8.99 related
to providing customers with information on how to save energy and money. Seventy-six
percent of large commercial and industrial respondents indicated they have participated in at
least one Idaho Power energy efficiency program. Of the large commercial and industrial survey
respondents who have participated in at least one Idaho Power energy efficiency program, 99%
are “very” or “somewhat” satisfied with the program.
Training and Education
In 2021, Idaho Power engineers, program staff, field representatives, and hired consultants
continued to provide technical training and education to help customers learn how to identify
opportunities to improve energy efficiency in their facilities. The company has found that these
activities increase awareness and participation in its energy efficiency and demand-response
programs and enhance customer program satisfaction. To market this service and distribute the
training schedule and resources, Idaho Power used its website, email, and Energy@Work
newsletter.
During each training session, the large commercial and industrial technical consultant, key
account energy advisors, or a program engineer gave an overview of the commercial and
industrial programs available to customers.
C&I Sector Overview
Page 110 Demand-Side Management 2021 Annual Report
As part of this outreach activity, Idaho Power collaborated with and supported stakeholders
and organizations, such as IDL, BOMA, and the American Society of Heating, Refrigeration, and
Air Conditioning Engineers (ASHRAE). Using Idaho Power funding, the IDL performed several
tasks aimed at increasing the energy efficiency knowledge of architects, engineers, trade allies,
and customers. Specific activities included sponsoring a BSUG, conducting Lunch & Learn
sessions at various design and engineering firms, and offering the ERL.
Idaho Power delivered six equivalent full-time days of technical live, online training sessions in
2021 at no cost to the customers over the course of 12 days. Topics included the following:
• Industrial Refrigeration
• Motors
• Variable Frequency Drives (VFD)
• Introduction to Unitary Air Conditioning
• Advanced Unitary Air Conditioning
• Harmonics
• Pumping Systems
The level of participation in 2021 remained high, with 221 individuals signing up and 208 unique
logins to the technical sessions. Due to the virtual nature of the course delivery, in some cases
there were multiple attendees at a single login location. Customer feedback indicated the
average satisfaction level was 91%. Idaho Power’s average cost to deliver the technical trainings
in 2021 was approximately $4,720 per class.
Also, Idaho Power offered eight technical, live, online training sessions to municipal water and
wastewater customers. Topics included the following:
• Water Energy Basics
• Activated Sludge Basics
• Primary Clarifier Optimization
• Pumping Energy Efficiency
• Controlling Activated Sludge
• Denitrification and Bio-P
• Low Cost/No Cost Opportunities
Water and wastewater trainings were attended by 262 participants. Cohort members and other
operators were invited and offered continuing education units for drinking water and
C&I Sector Overview

wastewater professionals. Each course is designed to study improved operation, quality, and
energy performance for different systems.
Aside from the classes listed above, Idaho Power also partnered with the NEEC to administer a
Building Operator Certification Level I Course that began in November 2021 and will continue
through May 2022. Idaho Power sponsored 17 customers who signed up for the training and
will pay $900 of the $1,895 tuition cost upon completion.
Field Staff Activities
Energy efficiency opportunities continue to be an important factor for most businesses.
Not only has there been ongoing interest in upgrading old, less efficient equipment, but there is
also a heightened interest to improve behaviors to meet new sustainability initiatives.
Idaho Power’s energy efficiency programs are designed to accommodate all possible
efficiency opportunities, ranging from equipment improvements to a variety of business
cohorts that offer support and ongoing training for a long-term, more sustainable approach
to energy efficiency.
Idaho Power has trained friendly and engaged energy advisors in each region to proactively
share these opportunities to influence change. While COVID-19 has presented challenges in
some areas with on-site visits in 2021, it has also opened doors to be creative in maintaining
close working relationships with customers. Online meetings and more frequent check-ins have
proven to be productive and effective with the company’s largest commercial
customers. Energy advisors have specific goals to maintain close working relationships and
COVID-19 did not negatively affect those goals. The company continued to offer commercial
building engineers, trade allies, and other stakeholders online technical training to help them
be successful with the ongoing promotion of energy efficiency opportunities.

Description
Three major program options targeting different energy efficiency projects are available to
commercial, industrial, governmental, schools, and small business customers in the company’s
Idaho and Oregon service areas: Custom Projects, New Construction, and Retrofits.
Custom Projects
The Custom Projects option provides incentives for non-lighting energy efficiency modifications
to new and existing facilities. The goal is to encourage energy savings in Idaho and Oregon
service areas by helping customers implement energy efficiency upgrades. Incentives reduce
customers’ payback periods for custom modifications and promote energy-saving operations
that might not otherwise be completed. The Custom Projects option also offers energy
assessment services to help identify and evaluate potential energy-saving modifications or
projects.
Interested customers submit a pre-approval application to Idaho Power for potential
modifications identified by the customer, Idaho Power, or a third-party consultant. Idaho Power
reviews each application and works with the customer and vendors to provide or gather
sufficient information to support the estimated energy savings calculations, then pre-approves
C&I Sector—Commercial and Industrial Energy Efficiency Program
Demand-Side Management 2021 Annual Report Page 113
the project. Then the customer moves forward with the project. In some cases, large, complex
projects may take as long as two or more years to complete.
Once the project is completed, customers submit a payment application, and each project is
reviewed to ensure energy savings are achieved. Idaho Power engineering staff or a third-party
consultant verifies the energy-savings methods and calculations. Through this verification
process, the final energy savings and the project costs are estimated.
On the larger and more complex projects, Idaho Power or a third-party consultant conducts on-
site power monitoring and data collection before and after project implementation. The M&V
process helps ensure projected energy savings are achieved. Verifying applicants’ information
confirms energy savings are obtained and are within program guidelines. If changes in project
scope take place, Idaho Power will recalculate energy savings and incentive amounts based on
the actual installed equipment and performance.
New Construction
The New Construction option enables customers in Idaho Power’s Idaho and Oregon service
areas to incorporate energy-efficient design features and technologies into new construction,
expansion, or major remodeling projects. Initiated in 2004, the New Construction option
currently offers incentives for 33 energy-saving building and design features related to efficient
lighting, lighting controls, building shell, HVAC equipment, HVAC controls, variable speed drives,
refrigeration, compressed air equipment, appliances, and other equipment. The customer may
otherwise lose savings opportunities for these types of projects. The new construction and
major renovation project design and construction process is much longer than small retrofits
and often encompasses multiple calendar years.
Retrofits
The Retrofits option is Idaho Power’s prescriptive measure option for existing facilities. This
part of the program encourages customers in Idaho and Oregon to implement energy efficiency
upgrades by offering incentives on a defined list of measures. Eligible measures cover a variety
of energy-saving opportunities in lighting, HVAC, building shell, food service equipment, and
other commercial measures. Customers can also apply for non-standard lighting incentives.
A complete list of the measures offered through Retrofits is included in Supplement 1:
Cost-Effectiveness.
Program Activities
Idaho Power has found that providing facility energy assessments, customer technical training,
and education services are key to encouraging customers to consider energy efficiency
modifications. The 2021 activities not already described in the Commercial/Industrial Sector
Overview are described below.
C&I Sector—Commercial and Industrial Energy Efficiency Program
Page 114 Demand-Side Management 2021 Annual Report
Custom Projects
Incentive levels for the non-lighting projects remained the same in 2021, at $0.18/kWh of first-
year savings, up to 70% of the project cost. The energy management incentive of $0.025/kWh
of first-year savings, up to 100% of the eligible costs (added in 2020), also remained the same in
2021. Energy management projects have the following benefits:
• Tend to have a shorter measure life and a much lower cost.
• Involve O&M changes that save energy without interrupting the customer’s service or
product.
• Generate cost-effective energy savings from measures rooted in low-cost or no-cost
O&M improvements.
Idaho Power provides incentives for conducting leak assessments and fixing underground water
leaks. The program reimburses $1,000 per five miles of pipe for a third-party leak assessment
and offers a custom incentive of $0.18/kWh saved up to 70% of the eligible cost to repair the
leaks for eligible underground pipes.
Compressed air system leak repairs are also eligible under the energy management incentive at
$0.025 per kWh saved up to 100% of project cost. Customers can use their own
instrumentation to identify compressed air leaks or work with one of Idaho Power’s third-party
consultants to identify leaks. Once leaks are identified, energy savings achieved from fixing
leaks can be quantified. Project costs are calculated by factoring in the material cost to fix the
leaks as well as any labor requirements. One of the third-party engineering consultants is
developing a tool that will help streamline the incentive process for this type of project.
Idaho Power funds the cost of engineering services, up to $4,500, for conducting energy
scoping assessments to encourage its larger customers to adopt energy efficiency
improvements. Idaho Power contracted with five firms to provide scoping assessments and
general energy efficiency engineering support services in 2021. A new RFP was issued in the fall
of 2021, and six successful bidders were selected to provide general energy efficiency
engineering services through 2025. Two of the firms that were selected are focused on energy
modeling to support cohorts and other SEM offerings. The other four firms provide a wide array
of engineering services, including scoping assessments, detailed assessments, energy modeling,
and various SEM programs.
The Custom Projects option had a successful year with a total of 135 completed projects, 20 of
which were in Oregon. Custom Projects achieved energy savings of 53,728 MWh (Table 16),
which is a 43% decrease compared to 2020. The year 2020 was an exceptional growth year in
terms of energy savings under the Custom Projects option (greater than 30% versus 2019),
and COVID had not yet impacted many of the projects. In 2021, almost all projects were slowed
down by materials and labor issues.
C&I Sector—Commercial and Industrial Energy Efficiency Program
Demand-Side Management 2021 Annual Report Page 115
Idaho Power also received 114 new applications in 2021 representing a potential of
40,577 MWh of savings on future projects.

Custom Projects engineers and the key account energy advisors visited large-commercial and
industrial customers to conduct initial facility walk-throughs, commercial/industrial efficiency
program informational sessions, and training on specific technical energy-saving opportunities
as pandemic and other conditions allowed. Virtual/remote capabilities were developed and
implemented when health or safety restrictions were necessary. Idaho Power also provided
sponsorship for the 2021 ASHRAE Technical Conference (virtual). Custom Projects engineers
gave presentations on Idaho Power programs and offerings at the Cohort for Schools Mid-term
and Final Workshops (virtual) and eight presentations at Water and Wastewater Cohort
Workshops (virtual).
In 2021, Idaho Power contractors completed 26 scoping assessments on behalf of Idaho Power
customers. These assessments identified over 28,984 MWh of savings potential and will be
used to promote future projects.
In 2013, a Streamlined Custom Efficiency (SCE) offering was started that works to keep vendor
engagement high, targeting projects that may have typically been too small to participate under
the Custom Projects option. Currently, the SCE offering provides custom incentives for
refrigeration controllers for walk-in coolers, process-related VFDs, and other small,
vendor-based projects that do not qualify for prescriptive incentives.
C&I Sector—Commercial and Industrial Energy Efficiency Program
Page 116 Demand-Side Management 2021 Annual Report
Idaho Power contracted with a third party to manage SCE data collection and analysis for each
project. In 2021, the SCE offering processed 24 projects totaling 4,096,687 kWh of savings and
$571,999 in incentives.
Cohorts
Idaho Power also has cohorts to engage with customers in group settings to allow customer
interaction and economies of scale in working with multiple customers on SEM.
The Municipal Water Supply Optimization Cohort (MWSOC), Eastern Idaho Water Cohort
(EIWC), Wastewater Energy Efficiency Cohort (WWEEC), and the Continuous Energy
Improvement (CEI) Cohort for Schools program offerings are also driving a significant number of
new projects in addition to increasing vendor engagement from the SCE offering.
Capital projects promoted or identified in SEM are reported and incentivized through other
Idaho Power C&I programs, not as a cohort savings number.
Cohorts are structured to offer three phases of support.
1. The active phase, which is typically the first two years of engagement with strong
consultant support, includes energy team development, energy policy development,
energy model creation, training and report-out workshops, energy champion and
team calls, and general energy awareness.
2. The maintaining phase includes medium consultant support and is typically years
three through five or six. This phase includes consultant maintenance of facility
energy models, monthly energy champion calls, report-out workshops, and ongoing
general development.
3. The sustaining phase is typically beyond year five or six where the participants
manage activities on their own including maintenance of energy models and ongoing
focus on energy-saving activities with little consultant support. Participants in this
phase will have the option to participate in report-out workshops but cohort-related
energy savings will no longer be claimed, and consultant support will be minimal.
Each cohort offering is described below.
Municipal Water Supply Optimization Cohort
The MWSOC began in January 2016. The goal of the cohort was to equip water professionals
with the skills necessary to independently identify and implement energy efficiency
opportunities that produce long-term energy and cost savings.
Fourth-year incentives and savings totaled $11,275 and 559,254 kWh per year with all
incentives paid at 70% of the eligible cost. Fourth-year incentives were processed, and savings
were reported in 2021.
C&I Sector—Commercial and Industrial Energy Efficiency Program
Demand-Side Management 2021 Annual Report Page 117
Fifth-year incentives and savings totaled $7,173 and 403,826 kWh per year with all incentives
paid at 70% of the eligible cost except one facility. Fifth-year incentives were processed, and
savings were reported in 2021.
Idaho Power continued the cohort for 11 of the original 15 participants and offered two
webinar trainings in late 2021. One participant will remain in the active phase and 10
participants will be transitioning to the sustaining phase. Idaho Power’s contractor minimally
contacted participants to check on project progress and opportunities and to address energy
model data updates.
Eastern Idaho Water Cohort
The EIWC began in January 2018 with the goal to offer the MWSOC to the eastern part of Idaho
Power’s service area. This was accomplished in collaboration with Rocky Mountain Power and
BPA to deliver joint workshops for customers located in eastern Idaho. Two Idaho Power
customers started at the beginning of this program and are in the active phase and will soon
transition to the sustaining phase. Third-year incentives were processed, and savings were
reported in 2021 totaling $2,392 and 674,892 kWh per year. In the third year of the offering,
Idaho Power’s contractor contacted participants to check on project progress and opportunities
and to address energy model data updates. A draft of the fourth-year energy-savings report is
expected in 2022.
Wastewater Energy Efficiency Cohort
In January 2014, Custom Projects launched WWEEC, a two-year cohort training approach and
incentives for low-cost or no-cost energy improvements for 11 municipal wastewater facilities
in Idaho Power’s service area. In 2016, Idaho Power decided to increase the duration of
WWEEC to further engage customers. Five of the 11 original participants are engaged in the
WWEEC Continuation with many of the original participants starting major construction
projects in years two and three of WWEEC.
Year six includes one facility that re-engaged with the cohort after major renovations.
The facility was re-baselined, and the sixth-year energy savings before adjusting for capital
projects were 591,226 kWh per year. After capital project adjustments, incentives and savings
were processed and reported in 2021, totaling $174 and 965 kWh per year. In the sixth year,
the consultant contacted the participant to check on progress, discuss opportunities, and to
address energy model data updates. Six participants are in the maintaining phase of
the program.
Continuous Energy Improvement Cohort for Schools
The goal of this cohort is to equip school district personnel with hands on training and guidance
to help them get the most out of their systems while reducing energy consumption. The fourth
program year of the Cohort for Schools ran from June 2020 through May 2021. Over this
C&I Sector—Commercial and Industrial Energy Efficiency Program
Page 118 Demand-Side Management 2021 Annual Report
program year, the structure of the offering was refined to include three phases of support:
active, maintaining, and sustaining.
Five school districts, of the original nine from 2017, continued to implement CEI concepts and
planned activities for the cohort. In October 2019, two new school districts began participating.
These districts developed their energy teams, built initial facility energy models, and went
through training on various aspects of CEI and energy efficiency through 2021.
Energy savings for the participants were evaluated from June 2020 through May 2021.
Activities were conducted through May 2021 to complete a full 12-month cycle and to work
around the standard school calendar for the participants. The cohort is implemented by a third-
party consultant that provided final savings reports for each school district, which totaled
4,556,394 kWh for 2021. In addition, one district saved 2,848,708 kWh through program year
four but was still providing backup documentation at the end of 2021, so these savings will be
claimed in 2022.
Fourth-year activities commenced over the summer of 2020, concluding at the end of May
2021. All seven participants entering this program year continued through 2021. Of those
seven, five districts are now modeling all schools in their district. One district added three new
facilities to the cohort, one added two new facilities, and another added one new facility in this
program year for a total of 41 facilities that are currently engaged with the offering.
Activities in 2021 included managing a register of energy efficiency opportunities for each
facility detailing low-cost and no-cost opportunities to reduce energy consumption. The
consultant worked with each participant to complete as many identified opportunities as
possible. Afterward, the consultant checked in monthly by phone to review opportunity register
items and to discuss current activities. Idaho Power provided program and incentive
information, both in hard copy and electronically, along with many other energy-saving
resources pertinent to school facilities.
A virtual mid-term workshop was held January 14, 2021, where school districts reported their
results through the end of 2020, and a final virtual workshop was held on June 29, 2021, where
final results were reported for the program year. Districts shared successes, lessons learned,
and other details pertinent to their energy-saving journeys.
The 2021 to 2022 program year activities will continue until May 31, 2022. Idaho Power will
then review final M&V reports to establish energy savings and eligible costs for the program
year activities and will distribute the corresponding incentives to participating school districts.
Green Motors Initiative
Idaho Power participates in the Green Motors Practices Group’s (GMPG) GMI. Under the GMI,
service center personnel are trained and certified to repair and rewind motors to improve
C&I Sector—Commercial and Industrial Energy Efficiency Program
Demand-Side Management 2021 Annual Report Page 119
reliability and efficiency. If a rewind returns a motor to its original efficiency, the process is
called a “Green Rewind.” By rewinding a motor under this initiative, customers may save up to
40% of the cost of a new motor. The GMI is available to Idaho Power’s agricultural, commercial,
and industrial customers.
Currently, nine motor service centers have signed on as GMPG members in Idaho Power’s
service area. Under the initiative, Idaho Power pays service centers $2 per horsepower (hp) for
each National Electrical Manufacturers Association (NEMA)-rated motor up to 5,000 hp that
receives a verified Green Rewind. Half of that incentive is passed on to the customer as a credit
on their rewind invoice. The GMPG requires all member service centers to sign and adhere to
the GMPG Annual Member Commitment Quality Assurance agreement. The GMPG is
responsible for verifying QA.
In 2021, a total of four commercial and industrial customers’ motors were rewound, and the
savings for the GMI was 20,430 kWh.
New Construction
In 2021, 95 projects were completed, resulting in 17,536,004 kWh of energy savings in Idaho
and Oregon. New Construction had a 20% reduction in total projects and a 20% increase in total
savings compared to 2020. The commercial and industrial construction industry has been
extremely active in Idaho Power’s service area throughout 2021, although the industry is
experiencing labor shortages and supply chain issues that have delayed, slowed, and
complicated some projects.
Maintaining a consistent offering is important for large projects with long construction periods;
however, changes are made to enhance customers’ choices or to meet new code changes.
Idaho Power tries to keep the New Construction option consistent by making changes
approximately every other year. The TRM has been updated to include 2018 IECC information
and was finalized in 2021. The program offerings were updated June 15, 2021, to reflect those
changes; along with the update, program offerings were reviewed to include new measures,
adjust existing measures, and review the cost-effectiveness of all measures. Overall,
seven program offerings were removed, and seven program offerings were added to align with
the updated TRM. The 2021 program offering includes 33 measures in Idaho and 25 measures
in Oregon.
In addition to the customer incentive, a Professional Assistance Incentive (PAI) is available to
architects and/or engineers for supporting technical aspects and documentation of a project.
The PAI is equal to 20% of the participant’s total incentive with a maximum allowed of $5,000
per application.
The PAI increases the engagement with architects and engineers and is most beneficial to small
and medium businesses as they prepare project documentation. These customers typically do
C&I Sector—Commercial and Industrial Energy Efficiency Program
Page 120 Demand-Side Management 2021 Annual Report
not have staff with a technical background in construction, which makes completing
applications and submitting documentation a challenge.
On September 23, 2020, Idaho Power increased the eligible PAI incentive from 10% to 20% of
the participant’s total incentive with a correspondingly increased maximum allowed from
$2,500 to $5,000 per application. In 2021, 40 projects, or 42% of the projects paid, received the
PAI compared to 40 projects, or 34% of the total projects paid, in 2020. The company decided
to continue the increased PAI after positive feedback from architects and engineers.
Idaho Power representatives did not make in-person visits to architectural and engineering
firms in Boise in 2021 due to COVID-19 restrictions, but they did continue discussions via phone
and email. These conversations are intended to build relationships with the local design
community and to discuss Idaho Power’s C&I Energy Efficiency Program.
The New Construction option continued random post-project verifications on 10% of projects
completed in 2021. The University of Idaho’s IDL did not complete on-site post-project
verifications in 2020, but rather completed desk reviews of all documentation. In 2021, the IDL
returned to on-site post-project verification on 12 of the 95 projects—over 10% of the total
completed. The purpose of the verifications is to confirm program guidelines and requirements
are adequate to ensure the supporting final project documentation provided aligns with field
installation. More discrepancies were identified in verified projects in 2021 than in previous
years. Idaho Power and the IDL will evaluate the process in 2022 and create a project
verification standard to include verification prior to payment for 10% of projects completed.
See Supplement 2: Evaluation for the complete IDL report.
The impact evaluation from 2019 had a recommendation to:
• Utilize [Hours of Use] HOUs from the TRM for lighting and HVAC projects started after
the TRM was implemented
• Also, the sources for the TRMs data are clearly cited and can be traced back to original
research. The TRM was updated in 2021 adding additional transparency
and clarification.
Retrofits
The Retrofits option achieved 21,181 MWh of energy savings in 2021, representing
787 projects. Lighting retrofits comprised most of the energy savings and project count.
In March 2021, Idaho Power rolled out an updated lighting tool for Retrofits lighting
applications. Enhancements were made to this version, such as consolidating two tabs into one,
and making the temporary incentive increases from 2020 permanent. In addition, fluorescent
fixture incentives were removed from the standard incentive menu to a non-standard
C&I Sector—Commercial and Industrial Energy Efficiency Program
Demand-Side Management 2021 Annual Report Page 121
incentive. Other lighting incentive menu changes were made in response to measure cost-
effectiveness review.
Retrofits staff conducted four virtual program workshops for trade allies and large customers to
inform them of the adjustments to the lighting measures and the upgrades to the lighting tool.
The Retrofits non-lighting measure savings and costs are determined by Idaho Power’s TRM.
In 2020, the company contracted with a third party to update its TRM. The work was completed
in 2021, and the TRM updates were incorporated into the Retrofits non-lighting option menu,
which resulted in incentive changes for several measures, the addition of new measures, and
the removal of others. The changes became effective in Idaho in June and in Oregon in
September 2021. Retrofits staff conducted three non-lighting webinars to review the changes
with trade allies and large customers.
Due to the continued COVID-19 pandemic, no in-person workshops occurred in 2021.
In September 2021, Idaho Power gave a virtual presentation as part of an International
Brotherhood of Electrical Workers (IBEW) Local 291 class in Boise on the available lighting
incentives and how electrical contractors could engage in the Retrofits option. In December
2021, Idaho Power hosted the Making Controls Simple: LLLC Myths & Installation Advantages
webinar for electrical contractors and suppliers, and large commercial customers. Continuing
education credits were given for electricians attending the webinar.
Idaho Power continued its contracts with various consultants to provide ongoing program
support for lighting and non-lighting reviews and inspections, as well as trade ally outreach.
Marketing Activities
Idaho Power continued to primarily market the C&I Energy Efficiency Program as a single
offering to businesses. See the Sector Overview for the company’s efforts to market the C&I
Energy Efficiency Program. Below are the option-specific marketing efforts for 2021.
Custom Projects
In addition to program-level marketing activities, Idaho Power continued to present large-
format checks to interested Custom Projects participants and publicized these events to local
media, when applicable. However, there were far fewer checks presented in-person in 2020
and 2021 than in previous years due to COVID-19 restrictions.
New Construction
Idaho Power updated its brochure in mid-2021 to reflect the new incentive information. The
company also sent a letter to 310 architects and engineers in August informing them of the new
incentives and providing them with a copy of the updated program overview brochure and
harmonics brochure.
C&I Sector—Commercial and Industrial Energy Efficiency Program
Page 122 Demand-Side Management 2021 Annual Report
The company continued to place banners on select construction sites highlighting that the
facility is being built or enhanced with energy efficiency in mind. A banner remained at St.
Luke’s McCall Medical Center throughout 2021.
Last, Idaho Power sponsored the American Institute of Architects (AIA) Idaho Chapter awards
event in Ketchum in September. The company’s logo appeared on all marketing materials, a
table tent promoting the New Construction option was placed on the tables, and print ads and
articles appeared in the event programs.
Retrofits
In 2021, Idaho Power updated its Retrofits brochure and split the information into two
brochures: one specific to Idaho customers and the other for Oregon customers. The company
also redesigned the Retrofits website so customers first choose which state the project will be
completed in, so they are directed to the incentives specific to that state.
The company placed a pop-up ad on My Account in September that resulted in 2,859 views and
160 click-throughs from business customers.
To promote the lighting incentives, Idaho Power developed a point-of-purchase display to place
at the checkout counter at 60 lighting suppliers. The displays received very positive comments
from suppliers. The company also sent out a lighting postcard to 1,400 businesses in October.
Throughout a portion of the year, the company also sent out emails promoting the lighting
incentives. The company’s customer solutions advisors then followed up by making personal
phone calls to customers who received the email.
Green Motors Initiative
In 2021, Idaho Power continued to promote GMI as part of the C&I Energy Efficiency Program
marketing efforts. The company posted about the program on social media in March and
December. Additionally, the program was featured in the summer Energy@Work
electronic newsletter.
Cost-Effectiveness
Custom Projects
Historically, all projects submitted through the Custom Projects option must meet
cost-effectiveness requirements, which include TRC, UCT, and PCT tests from a project
perspective. The program requires that all costs related to the energy efficiency
implementation and energy-savings calculations are gathered and submitted with the program
application. Payback is calculated with and without incentives, along with the estimated dollar
savings for installing energy efficiency measures. As a project progresses, any changes to the
project are used to recalculate energy savings and incentives before the incentives are paid to
the participant. To aid in gathering or verifying the data required to conduct cost-effectiveness
C&I Sector—Commercial and Industrial Energy Efficiency Program
Demand-Side Management 2021 Annual Report Page 123
and energy-savings calculations, third-party engineering firms are sometimes used to provide
an assessment, or engineering M&V services available under the Custom Projects option.
The UCT and TRC ratios for the program are 2.98 and 1.32, respectively. Non-energy impacts
were applied in 2021 based on an estimated per-kWh value by commercial and industrial end-
uses. These values were provided by a third-party as part of the 2019 impact evaluation of the
New Construction and Retrofits options. Details for the program cost-effectiveness are in
Supplement 1: Cost-Effectiveness.
New Construction
To calculate energy savings for the New Construction option, Idaho Power verifies the
incremental efficiency of each measure over a code or standard practice installation baseline.
Savings are calculated through two main methods. When available, savings are calculated using
actual measurement parameters, including the efficiency of the installed measure compared to
code-related efficiency. When precise measurements are unavailable, savings are calculated
based on industry standard assumptions. Because the New Construction option is prescriptive
and the measures are installed in new buildings, there are no baselines of previous measurable
kWh usage in the building. Therefore, Idaho Power uses industry standard assumptions from
the IECC to calculate the savings based on an assumed baseline, i.e., how the building would
have used energy absent of efficiency measures.
New Construction incentives are based on a variety of methods depending on the measure
type. Incentives are calculated mainly through a dollar-per-unit equation using square footage,
tonnage, operating hours, or kW reduction.
To prepare for the 2021 program changes, Idaho Power contracted with a third party to update
the TRM for the New Construction option. The TRM, which provides savings and costs related
to existing and new measures for the New Construction option, was updated to include the
IECC 2018 baseline. The new savings will be reflected on applications initiated after the June
2021 program update.
The UCT and TRC ratios for the program are 2.98 and 2.70, respectively. Non-energy impacts
were applied in 2021 based on an estimated per-kWh value by commercial and industrial end-
uses. These values were provided by a third party as part of the 2019 impact evaluation of the
New Construction and Retrofits options.
Complete, updated measure-level details for cost-effectiveness can be found in Supplement 1:
Cost-Effectiveness. Assumptions for measures prior to the mid-year update can be found in the
Demand-Side Management 2020 Annual Report, Supplement 1: Cost-Effectiveness.
Retrofits
For the first half of 2021, Idaho Power used most of the same savings and assumptions as were
used after the program changes in 2020 for the Retrofits option. For all lighting measures,
C&I Sector—Commercial and Industrial Energy Efficiency Program
Page 124 Demand-Side Management 2021 Annual Report
Idaho Power uses a Lighting Tool developed by a third party. An initial analysis was conducted
to see if the lighting measures shown in the tool were cost-effective based on the average input
of watts and hours of operation, while the actual savings for each project are calculated based
on specific information regarding the existing and replacement fixture. For most non-lighting
measures, deemed savings from the TRM or the RTF are used to calculate the
cost-effectiveness. To prepare for the 2021 program changes, Idaho Power contracted with a
third party to update the TRM for the Retrofits options. The TRM provides savings and costs
related to existing and new measures for the Retrofits option. The new savings will be reflected
on all applications submitted after the June 2021 program update.
The UCT and TRC ratios for the program are 2.53 and 1.27, respectively. Non-energy impacts
were applied in 2021 based on an estimated per-kWh value by commercial and industrial end-
uses. These values were provided by a third-party as part of the 2019 impact evaluation of the
New Construction and Retrofits options.
Complete updated measure-level details for cost-effectiveness can be found in Supplement 1:
Cost-Effectiveness. Assumptions for measures prior to the mid-year update can be found in the
Demand-Side Management 2020 Annual Report, Supplement 1: Cost-Effectiveness.
Customer Satisfaction
Retrofits
In 2021, a survey was sent to customers who had a lighting project installed by a contractor to
evaluate the customers’ satisfaction level for the contractors listed on the Retrofits website.
Survey questions gathered information about how customers learned of the program and their
satisfaction with the program, contractor, and equipment.
A survey invitation was sent to 497 program participants in 2021. Idaho Power received survey
results from 125 respondents. Some highlights include the following:
• Over 53% of respondents learned of the program from a contractor, and over 14%
learned of the program from an equipment supplier.
• 88% of respondents said they were “very satisfied” with the program, and over 11% of
respondents indicated they were “somewhat satisfied.”
• 92% of respondents said they were “very satisfied” with the contractor they hired to
install their equipment, and over 6% of respondents indicated they were
“somewhat satisfied.”
• Nearly 93% of respondents said they were “very satisfied” with the equipment installed,
and nearly 6% of respondents said they were “somewhat satisfied.”
A copy of the survey results is included in Supplement 2: Evaluation.
C&I Sector—Commercial and Industrial Energy Efficiency Program
Demand-Side Management 2021 Annual Report Page 125
Evaluations
In 2021, Idaho Power contracted with a third party to conduct impact and process evaluations
of the C&I Custom Projects program. The evaluation found a successfully run program that has
mitigated many of the risks associated with custom energy efficiency programs. The evaluation
team identified only minor adjustments to claimed savings and calculated a realization rate of
99.8%.
The impact evaluation recommends maintaining the long-term focus of the cohorts’ projects,
continuing to build relationships in the market, and considering the use of a consumption
analysis approach for determining energy savings, where necessary. The process evaluation
recommends updating the commercial and industrial program logic model to include recent
program updates, adding a new construction or equipment replacement check box for the
program application, and continuing to focus on efficient and effective communication
between all parties.
Idaho Power will consider all recommendations made in the report, and any changes to the
program will be reported in the Demand-Side Management 2022 Annual Report. See the
complete analysis report in Supplement 2: Evaluation.
2022 Program and Marketing Strategies
In 2022, the three options will continue to be marketed as part of Idaho Power’s C&I Energy
Efficiency Program. Below are specific program strategies that apply to the individual options of
the program.
Custom Projects
In 2022, the company plans to expand deployment of the newly developed energy
management commercial energy-savings tool, Find n’ Fix, which, in conjunction with
engineering services, will help identify and quantify energy savings opportunities for
commercial customers. Also, the compressed air leak detection and repair offering that is
available to larger customers, like the water leak measure launched in 2020, will be marketed
and expanded in 2022.
Activities and coaching will continue for the water and wastewater cohort participants and the
EIWC. Preliminary planning to implement a new cohort based on industrial wastewater is being
conducted. This cohort will focus on a more technical approach to energy savings than the
other water and wastewater cohorts. The estimated implementation of this cohort will be early
2022.
Idaho Power will continue to provide the following:
• In-person or virtual site visits and energy scoping assessments by Custom Projects
engineers to identify projects and energy savings opportunities as conditions allow.
C&I Sector—Commercial and Industrial Energy Efficiency Program
Page 126 Demand-Side Management 2021 Annual Report
• Funding for detailed energy assessments for larger, complex projects. Virtual
assessments can also be offered in many cases.
• M&V of larger, complex projects. Virtual M&V can also be used as conditions allow.
• Technical training for customers, presented virtually or in person as conditions allow.
New Construction
In 2021, more discrepancies were identified in verified projects than in previous years. Idaho
Power and the IDL will evaluate the project verification process in 2022 and create a standard
that includes verification prior to payment on a minimum of 10% of completed projects. The
2022 evaluation and process update will improve the verification process and reduce
discrepancies.
As in past years, Idaho Power will continue to build relationships in 2022 by sponsoring
technical training through the IDL to address the energy efficiency education needs of design
professionals throughout Idaho Power’s service area.
Retrofits
Idaho Power will offer two lighting-related technical trainings to trade allies and large
commercial customers in 2022.

Description
The Commercial Energy-Saving Kit (Commercial ESK) program is offered to commercial business
customers in Idaho and Oregon. Three industry-specific types are available for restaurants,
retailers, and offices (Table 17)—and each contains installation instructions and a variety of
items intended to help save energy related to lighting, hot-water use, and intermittently used
electrical devices. Idaho Power uses a third-party vendor for kit assembly and mailing. The
vendor sends the kit through the mail directly to the customer on the company’s behalf.

The vendor also batch-ships kits to Idaho Power area offices for distribution by its energy
advisors. An energy advisor may then deliver a Commercial ESK while visiting a small business
customer and use it as an introduction to the benefits of the other commercial energy
efficiency programs offered by the company.
C&I Sector—Commercial Energy-Saving Kits
Page 128 Demand-Side Management 2021 Annual Report
Program Activities
The vendor made no batch shipments in 2021 due to in-person customer visits being drastically
reduced because of COVID-19 restrictions. However, Idaho Power continued to offer
Commercial ESKs, with a primary focus on small business customers. Nearly all the kits were
distributed by mail in 2021.
Idaho Power distributed 906 kits (Table 18), most of which were distributed after a customer
made a request through the website or spoke with a company representative on the phone.
A modified RFP was sent to three third-party kit vendors who are currently contracted with
Idaho Power or who have been in the recent past. The RFP asked only for pricing on a
shortened list of kit items. Due to cost-effectiveness or the RTF deactivating a few of the kit
items, they were omitted. The vendor with the lowest kit cost was selected.
Table 18. Energy savings by type and number of Commercial ESKs distributed

Retail 51 10,940
Office 611 108,233
Oregon Restaurant 12 9,517
Retail 2 429
Office 24 4,251

Marketing Activities
Idaho Power promoted the Commercial ESKs using LinkedIn posts in February and July.
Additionally, the kits were promoted on Facebook, Twitter, and LinkedIn in November in
support of Small Business Saturday.
The company displayed a pop-up ad to small business customers who logged into My Account
in March, resulting in 417 kit orders. Customers signing into My Account clicked on the pop-up
ad and requested a kit through the online order form. The form generated an email that was
sent directly to the program specialist, who fulfilled the order.
In May, the company tried a new tactic by sending a targeted email to 478 restaurants. This
tactic resulted in 158 kit orders, many of them restaurant kits, but the other two kit types were
distributed as well. The company sent a targeted email to 485 retail customers in November
that resulted in 49 kits ordered of all kit types.
Cost-Effectiveness
Because no deemed savings values exist for the Commercial ESK program, Idaho Power made
several assumptions for each kit. When the offering launched in mid-2018, the installation rates
C&I Sector—Commercial Energy-Saving Kits
Demand-Side Management 2021 Annual Report Page 129
of the items in the kit were unknown. Idaho Power estimated the installation rates based on
professional judgement. A follow-up survey was sent to active participants in November 2020
with an added question regarding fuel type to determine the percentage of electric water
heaters. When the kits are distributed, the water heating fuel source is often unknown. Idaho
Power updated this assumption in 2021 based on the follow-up survey sent to customers
in 2020.
For the LEDs and aerators, savings vary by kit type based on the average annual HOU and
annual gallons of water used by business type. Savings for the pre-rinse spray valve in the
restaurant kit, and advance power strips for the office kits, were directly from the RTF. Based
on the updated savings assumptions, restaurant, retail, and office kits provide approximately
793, 215, and 177 kWh of savings respectively.
In 2021, the RTF reviewed the savings associated with the pre-rinse spray valve and the
advanced power strips. For pre-rinse spray valves, the federal standards changed in 2019, and
the current standards already met or exceeded the WaterSense specifications. WaterSense has
not released a new, more efficient specification. As a result, the RTF deactivated the workbook,
and there are no savings associated with the pre-rinse spray valves; the restaurant kit savings
declined to 665 kWh.
In regard to the advanced power strips, the RTF found there was large uncertainty around the
savings estimates, and more research is needed. Because the measure is shown to be not cost-
effective for the region and many office computers already have energy-saving features, a
decision was made to deactivate the workbook. Therefore, there are no savings associated with
the advanced power strips going forward, and the savings for the office kits decline to
approximately 117 kWh. Because of this, the office kits would not be cost-effective as a
standalone kit.
At the November EEAG meeting, Idaho Power shared the cost-effectiveness challenges for the
kit program and proposed four possible options. With direction from EEAG, it was decided to
simplify the offering to one kit, continue sending the kit per customer request, and track the
business type ordering the kit.
The Commercial ESK contract with the existing third-party vendor ended as of December 31,
2021, and a new contract featuring the condensed version of the kit with a plain box and
minimal marketing to reduce kit costs will be effective in early 2022. The kit distribution will
remain dependent on a customer request or through an Idaho Power employee.
For more information about the cost-effectiveness savings and assumptions, see Supplement 1:
Cost-Effectiveness.
C&I Sector—Commercial Energy-Saving Kits
Page 130 Demand-Side Management 2021 Annual Report
Customer Satisfaction
With customer survey numbers remaining small, it is difficult to quantify the program
satisfaction based on the small percentage of surveys returned. Anecdotally, the program
specialist received multiple emails with a “thank you” included after the kit was ordered. With
the new third-party kit vendor, an emphasis will be placed on survey returns and asking for the
fuel source and business type within the survey. The third-party vendor has offered to include
survey follow-up and rewards in their contract.
2022 Program and Marketing Strategies
In 2022, Idaho Power anticipates working with the new third-party vendor for Commercial ESK
distribution to small business customers. Once the contract is finalized, the marketing activities
scheduled include a LinkedIn post and an online pop-up during quarter three or four during the
My Account login. Additionally, a kit may be included as one of the welcome offerings when
Idaho Power calls new business customers. The online order form will remain available through
the company’s website, and Idaho Power employees will have the option to distribute the kit
while visiting eligible small business customers.

Description
The Flex Peak Program is a voluntary program where participants are eligible to earn a financial
incentive for reducing load. The program is available to Idaho and Oregon commercial and
industrial customers with the objective to reduce the demand on Idaho Power’s system during
periods of extreme peak electricity use.
Program event guidelines include the following:
• June 15 to August 15 (excluding weekends and holidays)
• Up to four hours per day between 2 and 8 p.m.
• Up to 15 hours per week
• No more than 60 hours per season
• At least three events per season
Customers with the ability to offer load reduction of at least 20 kW are eligible to enroll in the
program. The 20-kW threshold allows a broad range of customers to participate in the program.
Participants receive notification of a load reduction event two hours before the start of the
event.
C&I Sector—Flex Peak Program
Page 132 Demand-Side Management 2021 Annual Report
The program originated in 2009 as the FlexPeak Management program managed by a third-
party contractor. In 2015, Idaho Power took over full administration and changed the name to
Flex Peak Program. The IPUC issued Order No. 33292 on May 7, 2015, while the OPUC approved
Advice No. 15 03 on May 1, 2015, authorizing Idaho Power to implement an internally managed
Flex Peak Program (Schedule No. 82 in Idaho and Schedule No. 76 in Oregon) and to continue
recovering its demand response program costs in the previous manner.
Program Activities
In 2021, 61 participants enrolled 139 sites in the program. Existing customers were
automatically re-enrolled. Participants had a committed load reduction of 36 MW in the first
week of the program and ended the season with a committed load reduction of 29.7 MW.
The estimated maximum capacity of the program came from the nominated amount in the first
week of the season at 36 MW.
This weekly commitment, or nomination, was comprised of all 139 sites. The maximum
realization rate during the season was 106%, and the average for the five events was 78%. The
realization rate is the percentage of load reduction achieved versus the amount of load
reduction committed for an event. The highest hourly load reduction achieved was 30.6 MW
(at generation level) during the June 28 event (Table 19).

Event performance and realization rates for the 2021 season were similar to prior years in the
program with the exception of 2020 due to COVID-19 impacts.
Marketing Activities
Though the terms of IPUC Order No. 32923 and OPUC Order No. 13-482 do not require program
marketing, Idaho Power energy advisors regularly communicated with interested customers
and current participants and encouraged them to enroll new sites.
In 2021, the company ran a My Account pop-up ad promoting enrollment to large commercial
customers. Additionally, a LinkedIn post in April promoted program enrollment and a thank you
note to participants was posted on LinkedIn in August. The company also continued to include
the Flex Peak Program in its C&I Energy Efficiency Program collateral. Additional details can be
found in the Commercial/Industrial Sector Overview.

Cost-Effectiveness
Idaho Power determines cost-effectiveness for its demand response program under the terms
of IPUC Order No. 32923 and OPUC Order No. 13 482. Under the terms of the orders and the
settlement, all of Idaho Power’s demand response programs were cost-effective for 2021.
The Flex Peak Program was dispatched for 20 event hours and achieved a maximum load
reduction of 30.6 MW. The total cost of the program in 2021 was $501,973. Had the Flex Peak
Program been used for the full 60 hours, the cost would have been approximately $707,473.
A complete description of Idaho Power cost-effectiveness of its demand response programs is
included in Supplement 1: Cost-Effectiveness.
Evaluations
As required each year by the IPUC and OPUC, Idaho Power conducted an internal evaluation
of the program’s potential load-reduction impacts. A copy of this study is in Supplement 2:
Evaluation.
In preparation for program changes and to gather customer feedback, the company conducted
a survey in early summer 2021 and held an informational webinar in the fall to share possible
program changes identified in preparing the 2021 IRP. See the complete survey results in
Supplement 2: Evaluation.
Additionally, Idaho Power engaged a third-party contractor to conduct an impact evaluation of
the Flex Peak Program. The evaluation found the Flex Peak Program to have been operated
effectively in 2021, and the method for calculating demand reductions to have been
appropriately applied with only minor discrepancies, mostly related to rounding practices.
The evaluation calculated an average realization rate of 77.7%, compared with Idaho Power’s
calculation of 77.9%. The realization rate is calculated as the percentage of load reduction
achieved (average demand reduction) divided by the amount of load reduction committed
(average nominated reduction). The evaluation stated the current 3-in-10 baseline
methodology is appropriate and recommended consistent rounding practices; a streamlined
analytical approach through computer scripting; developing documentation regarding rules for
handling errors, missing data and other data validation steps; and continuing to work with
customers to refine their nominated load reductions. See the complete analysis report in
Supplement 2: Evaluation.
Idaho Power will consider all recommendations made in the impact evaluation, and any
changes to the program will be reported in the Demand-Side Management 2022 Annual Report.
2022 Program and Marketing Strategies
For the 2022 program season, Idaho Power will implement changes recently authorized by the
IPUC and OPUC, including lengthening the season to September 15; changing the event window
C&I Sector—Flex Peak Program
Page 134 Demand-Side Management 2021 Annual Report
to later in the evening; increasing the variable incentive; changing the threshold from three to
four events for when the variable incentive is paid; modifying the non-performance penalty for
events after the first three; and modifying the day-of adjustment calculation.
The company will continue to communicate the program value with enrolled customers and the
importance of active participation when events are called. Idaho Power will meet with existing
participants during the off-season to discuss past season performance and upcoming season
details.
For the upcoming season, Idaho Power will continue its focus on retaining currently enrolled
participants and will consider using email marketing and other new tactics to boost program
enrollment, with a focus on enrolling national chain stores within Idaho Power’s service area.
The program will also continue to be marketed along with the C&I Energy Efficiency Program.

Description
Oregon Commercial Audits identifies opportunities for all Oregon commercial and industrial
building owners, governmental agencies, schools, and small businesses to achieve energy
savings. Initiated in 1983, this statutory required program (ORS 469.865) is offered under
Oregon Tariff Schedule No. 82.
Through this program, Idaho Power provides no-cost energy audits, evaluations, and
educational products to customers through a third-party contractor. During the audits, the
contractor inspects the building shell, HVAC equipment, lighting systems, and operating
schedules, if available, and reviews past billing data. These visits provide an opportunity for the
contractor to discuss available incentives and specific business operating practices for energy
savings. The contractor may also distribute energy efficiency program information and remind
customers that Idaho Power personnel can offer additional energy-savings tips and
information. Business owners can decide to change operating practices or make capital
improvements designed to use energy wisely.
Program Activities
In 2021, the program contractor conducted three audits at separate facilities for one customer.
COVID-19 restrictions still had an impact on this program in 2021, as in-person site visits were
reduced from prior years, and certain customers still had their own business policies that
limited in-person visits.
C&I Sector—Oregon Commercial Audits
Page 136 Demand-Side Management 2021 Annual Report
Marketing Activities
Idaho Power sent its annual direct-mailing to 1,590 Oregon commercial customers in August to
explain the program’s no-cost or low-cost energy audits and the available incentives and
resources.
Cost-Effectiveness
As previously stated, the Oregon Commercial Audits program is a statutory program offered
under Oregon Schedule 82, the Commercial Energy Conservation Services Program. Because
the required parameters of the Oregon Commercial Audits program are specified in Oregon
Schedule 82 and the company abides by these specifications, this program is deemed to be
cost-effective. Idaho Power claims no energy savings from this program.
2022 Program and Marketing Strategies
Idaho Power does not expect to make any operational changes in 2022. The company will
continue to market the program through the annual customer notification and will consider
additional opportunities to promote the program to eligible customers via its energy advisors.

Description
Idaho Power launched the SBDI program in November 2019 targeting typically hard-to-reach,
small business customers in Idaho who use less than 25,000 kWh annually. Idaho Power pays
100% of the cost to assess eligibility and install lighting measures for these customers, using a
third-party contractor to operate the program. SBDI is offered to eligible customers in a
strategic geo-targeted approach.
Program Activities
In 2021, the company continued offering the SBDI program to customers in eastern Idaho,
adding the company’s southern portion of the South-East Region in June. Idaho Power sent
direct-mail letters to customers informing them of their eligibility to participate, and the
contractor followed up with calls offering another opportunity to hear about the program and
to declare their interest in participating. As customers responded to the letters and follow-up
calls, lighting assessments were scheduled. Customers who agreed to have LEDs installed at
their facility were scheduled for project installation. The SBDI contractor continued to
implement COVID-19 safety protocols and scheduled 561 lighting assessments, completed
452 project installations, and completed 55 post-installation inspections.
C&I Sector—Small Business Direct Install
Page 138 Demand-Side Management 2021 Annual Report
The Southern Region energy advisors began sending thank-you cards to participating SBDI
customers in 2021.
Marketing Activities
Idaho Power sent 913 direct-mail letters to business customers in the Eastern Region and 1,869
letters to business customers in the Southern Region in 2021. The program contractor followed
up with 1,900 phone calls about a week after they received the letter, resulting in 561
scheduled lighting assessments.
Cost-Effectiveness
In 2021, the projects in the SBDI program were all lighting upgrades. Idaho Power’s third-party
contractor calculates the savings based on the existing fixture wattage, the replacement fixture
wattage, and the HOU. The UCT and TRC ratios for the program are 0.99 and 1.54 respectively.
Non-energy impacts were applied in 2021 based on an estimated per kWh value by commercial
and industrial end-uses. These values were provided by a third-party as part of the 2019 impact
evaluation of the New Construction and Retrofits options. The cost-effectiveness ratios include
the costs associated with the 2020 process evaluation which was completed in 2021. If the
evaluation costs are removed, the UCT and TRC ratios for the program would be 1.00 and 1.55
respectively. The company will continue to monitor the programs cost-effectiveness as it
expands the offering to the Capital and Canyon-West regions (Figure 2) of the service area
in 2022.
Details for the program cost-effectiveness are in Supplement 1: Cost-Effectiveness.
Customer Satisfaction
Idaho Power’s third-party program implementer sent 452 customer satisfaction surveys to
program participants in 2021, of which 139 surveys were completed. Key highlights include the
following:
• Over 96% of respondents said they were “very satisfied” with the program, and nearly
3% of respondents indicated they were “somewhat satisfied.”
• Nearly 96% of respondents reported they were “very satisfied” with the equipment
installed, and nearly 4% of respondents indicated they were “somewhat satisfied.”
• All respondents found the program easy to participate in, with nearly 98% indicating the
program was “very easy” and over 2% reporting it was “somewhat easy” to
participate in.
• All respondents reported they would be likely to recommend the program to other
small businesses, with nearly 98% saying they were “very likely” and over 2% saying
they were “somewhat likely” to recommend the program.
C&I Sector—Small Business Direct Install
Demand-Side Management 2021 Annual Report Page 139
• When asked how their opinion of Idaho Power has changed since participating in the
program, over 58% of respondents reported having a more favorable opinion of
Idaho Power, and just over 42% of respondents reported no change in opinion.
A copy of the survey results is included in Supplement 2: Evaluation.
Evaluations
Idaho Power contracted a third party to conduct a process evaluation for the SBDI program.
The evaluation was intended to be completed in 2020; however, due to COVID-19 restrictions,
the evaluation was delayed allowing for additional installations. The evaluation found that
Idaho Power and its program implementers developed strategies and documentation, and
made effective early adjustments, that resulted in a successful launch of the new program.
Following are the recommendations of the process evaluation and Idaho Power’s response
to each.
• Continue to monitor how lessons learned in each region affect the contents of the
Outreach Plan and Program Operations Manual. The SBDI team holds region wrap-up
meetings, as well as annual program review meetings, to identify lessons learned. A plan
is then developed to address the lessons learned, and updates are incorporated into the
Outreach Plan and Program Operations Manual, as needed. This process will continue
through the duration of the SBDI program.
• Consider additional customer satisfaction follow-up with nonresponding customers.
Idaho Power will work with the SBDI contractor to identify the nonresponding
customers, and Idaho Power will begin sending follow-up email surveys in 2022 to
customers who did not respond to the survey from the SBDI contractor.
• Review insurance requirements with the SBDI contractor. Idaho Power discussed this
recommendation with the SBDI contractor in 2021. They were able to adjust some of
the insurance requirements to help address a barrier to installer recruitment.
• Work with the SBDI contractor to ensure a streamlined and efficient process for
contractors if reimbursement amounts cannot be increased. In 2022, the SBDI contractor
will begin conducting quality checks on the assessments performed on larger and/or
more complex projects prior to scheduling the installation appointment with the
customer. The intent of this pre-installation quality check is to ensure the scope of work
the installer receives is accurate. This will ensure the installer has the correct equipment
to perform the work and understands the installation details. In addition, the SBDI
contractor will use geo-targeted mapping when assigning projects to installers to reduce
travel time between installations.
C&I Sector—Small Business Direct Install
Page 140 Demand-Side Management 2021 Annual Report
• Continue to improve the process for preparing the customer for the installation. Idaho
Power’s SBDI contractor began addressing this recommendation in 2021. Steps taken to
better prepare customers for the installation phase included: adding a one-page
document to the enrollment form that highlights installation-day expectations; an SBDI
field representative verbally communicating to customers what to expect with their
particular installation (e.g., any lighting fixtures that are out-of-scope and the reason);
and the SBDI call center representative reminding some customers to move equipment
or other items to allow installation access.
See the complete analysis report in Supplement 2: Evaluation.
2022 Program and Marketing Strategies
Idaho Power will continue to operate and market this program as described above.
The company plans to continue to roll out the offering as planned to its Capital and Canyon
regions in 2022, which will include some Oregon areas.

Irrigation Sector Overview
Demand-Side Management 2021 Annual Report Page 141
Irrigation Sector Overview
The irrigation sector is comprised of agricultural customers operating water pumping or water
delivery systems to irrigate agricultural crops or pasturage. End-use electrical equipment
primarily consists of agricultural irrigation pumps and center pivots. The irrigation sector does
not include water pumping for non-agricultural purposes, such as the irrigation of lawns, parks,
cemeteries, golf courses, or domestic water supply.
In July 2021, the active irrigation service locations totaled 21,063 system-wide, which is an
increase of 1.2% compared to July 2020. The increase is primarily caused by adding service
locations for pumps and center pivot irrigation systems as land is converted from furrow and
surface irrigation to sprinkler irrigation.
Irrigation customers accounted for 2,125,733 MWh of energy usage in 2021, versus
1,987,418 MWh in 2020. The approximately 7% increase is primarily because of less rain
during the irrigation season and hotter weather. This sector represented nearly 13.7% of Idaho
Power’s total electricity sales, and approximately 27% of July sales. Though annual electricity
use may vary substantially for weather-related reasons, and there are now more irrigation
customers, the energy usage trend for this sector has not changed significantly in many
years because of the following:
• The added energy usage from new customers is relatively small compared to the energy
use of the average existing customer.
• Ongoing improvements through energy efficiency efforts and system replacement offset
much of the added energy use.
The Irrigation Efficiency Rewards program, including the GMI, experienced decreased annual
savings: from 12,884 MWh in 2020 to 9,700 MWh in 2021. This is due primarily to a decrease in
the savings from small maintenance upgrades in the Menu portion of the program.
Idaho Power re-enrolled the majority of 2020 Irrigation Peak Rewards participants in 2021,
with 2,235 service points and a maximum load reduction potential of 319.5 MW. Table 20
summarizes the overall expenses and program performance for both programs and shows the
actual load reduction was 255.5 MW on June 28, with three groups participating in the load
reduction event.

Energy Efficiency Programs
Irrigation Efficiency Rewards. An energy efficiency program designed to encourage customers
to replace or improve inefficient irrigation systems and components. Customers receive
incentives through the Custom Incentive Option for extensive retrofits and new systems and
through the Menu Incentive Option for small maintenance upgrades.
Green Motor Initiative. Under the GMI, service center personnel are trained and certified to
repair and rewind motors to improve reliability and efficiency. If a rewind returns a motor to its
original efficiency, the process is called a “Green Rewind.” Idaho Power pays service centers to
rewind qualified irrigation motors. Half of this incentive is then given to the customer as a
credit on the rewind invoice.
Demand Response Program
Irrigation Peak Rewards. A program designed to reduce peak load from irrigation pumps.
Participating service points are automatically controlled by Idaho Power switches or manually
interrupted by the customer for very large pumping installations or when switch
communication is not available.
Marketing
In 2021, the company mailed a winter edition of Irrigation News to all irrigation customers in its
service area. In part, the newsletter educated customers about how to sign up for new or
upgraded service and communicated changes about the Irrigation Efficiency Rewards program.
The application was put into a tear-pad version so during one-on-one visits, agricultural
representatives (ag reps) could easily tear off an application and provide to irrigator.
Irrigation Sector Overview
Demand-Side Management 2021 Annual Report Page 143
The company also placed numerous ads in print agricultural publications to reach the target
market in smaller farming communities. Publications included the Capital Press, Power County
Press/Aberdeen Times, Potato Grower magazine, Owyhee Avalanche, and The Ag Expo East and
West programs. Idaho Power used radio advertising to show support for the Future Farmers of
America and Ag Week conferences.
January through March, the company ran 726 radio ads promoting the Irrigation Efficiency
Rewards program. The 30-second spots ran in eastern and southern Idaho on a variety of
stations, including news/talk, sports, classic rock, adult hits, and country. Social media was used
to promote virtual irrigation workshops in quarter 1.
Customer Satisfaction
Idaho Power conducts the Burke Customer Relationship Survey each year. In 2021, on a scale of
zero to ten, irrigation survey respondents rated Idaho Power 8.03 regarding offering programs
to help customers save energy, and 7.98 related to providing customers with information on
how to save energy and money. Thirty-three percent of irrigation respondents indicated they
have participated in at least one Idaho Power energy efficiency program. Of the irrigation
survey respondents who have participated in at least one Idaho Power energy efficiency
program, 96% are “very” or “somewhat” satisfied with the program.
Training and Education
Idaho Power continued to market its irrigation programs by varying the location of workshops
and offering new presentations to irrigation customers.
In 2021, during to COVID-19 restrictions, Idaho Power provided three virtual and three in-
person irrigation workshops and participated in two additional vendor-hosted workshops
promoting the Irrigation Efficiency Rewards program; due to COVID-19 restrictions, this number
was lower than a typical year. Approximately 150 customers attended virtual workshops or
in-person workshops held in Caldwell, Mountain Home, and Weiser, Idaho. Due to COVID-19
restrictions the company did not participate in or have exhibits at any agricultural trade shows.
Field Staff Activities
Idaho Power ag reps were available to be on-site with customers for several months in 2021,
offering Idaho Power energy efficiency and demand response program information; education;
training; and irrigation system assessments and audits across the service area. Early in 2021,
due to COVID-19 restrictions, ag reps were only able to stay in contact with their customers via
phone call, email, and text. Later in 2021 on-site work resumed, adhering to COVID-19 safety
protocols.
Also, in 2021, ag reps continued their engagement with agricultural irrigation equipment
dealers with the goal of sharing expertise about energy-efficient system designs and increasing
Irrigation Sector Overview
Page 144 Demand-Side Management 2021 Annual Report
awareness about the program. Ag reps and the irrigation segment coordinator, a licensed
agricultural engineer, participated in training sponsored by the nationally based
Irrigation Association to maintain or obtain their Certified Irrigation Designer and Certified
Agricultural Irrigation Specialist accreditations.

Description
Initiated in 2003, the Irrigation Efficiency Rewards program encourages energy-efficient
equipment use and design in irrigation systems. Qualified irrigators in Idaho Power’s service
area can receive financial incentives and reduce their electricity usage through participation in
the program. Two options help meet the needs for major or minor changes to new or existing
systems: Custom Incentive and Menu Incentive. Irrigation customers can also qualify for an
incentive when they “rewind” their irrigation motors.
Custom Incentive Option
The Custom Incentive Option is offered for extensive retrofits to existing systems or the
installation of an efficient, new irrigation system.
For a new system, Idaho Power determines whether the equipment is more energy efficient
than the standard before approving the incentive. If an existing irrigation system is changed to
a new water source, it is considered a new irrigation system under this program. The incentive
for a new system is 25 cents per annual kWh saved, not to exceed 10% of the project cost.
Irrigation Sector—Irrigation Efficiency Rewards
Page 146 Demand-Side Management 2021 Annual Report
For existing system upgrades, the incentive is 25 cents per annual kWh saved or $450 per kW
demand reduction, whichever is greater. The incentive is limited to 75% of the total project
cost.
The qualifying energy efficiency measures include any hardware changes that result in a
reduction of the potential kWh use of an irrigation system or that result in a potential demand
reduction. Idaho Power reviews, analyzes, and makes recommendations on each project after
considering prior usage history, invoices, and, in most situations, post-installation demand data
to verify savings and incentives.
Menu Incentive Option
The Menu Incentive Option covers a portion of the costs of repairing and replacing specific
components that help the irrigation system use less energy. This option is designed for systems
where small maintenance upgrades provide energy savings from these 11 measures:
• New flow-control type nozzles
• New nozzles for impact, rotating, or fixed head sprinklers
• New or rebuilt impact or rotating type sprinklers
• New or rebuilt wheel-line levelers
• New complete low-pressure pivot package (sprinkler, regulator, and nozzle)
• New drains for pivots or wheel-lines
• New riser caps and gaskets for hand lines, wheel lines, and portable main lines
• New wheel-line hubs (Thunderbird)
• New pivot gooseneck and drop tube
• Leaky pipe repair
• New center pivot base boot gasket
Incentives are based on a predetermined kWh savings per component from the RTF. Based on
the evaluation of the RTF completed in 2021, the kWh annual savings changed for many
components with some components being removed because the savings were no longer
supported. On January 1, 2022, Idaho Power changed the list of eligible components to exclude
new wheel-line hubs, goosenecks, pipe repair and center pivot base boot gaskets. Any invoice
dated prior to January 1, 2022, will be eligible for the previous measures and incentive amounts
for up to one year from the date of the invoice.
Irrigation Sector—Irrigation Efficiency Rewards
Demand-Side Management 2021 Annual Report Page 147
Green Motors Initiative
Idaho Power also participates in the GMPS’s GMI. Under the initiative, Idaho Power pays service
centers $2 per hp for motors 15 to 5,000 hp that received a verified Green Rewind. Half of that
incentive is passed on to irrigation customers as a credit on their rewind invoice.
Program Activities
In 2021, 1,019 projects were completed as follows: 867 used the Menu Incentive Option and
provided an estimated 4,608 MWh of energy savings, and 152 used the Custom Incentive
Option and provided 5,073 MWh of energy savings (87 new systems and 65 existing systems).
Also, a total of 12 irrigation customers’ motors were rewound under the GMI and accounted for
19,352 kWh in savings.
In 2020, Idaho Power contracted with a third party to conduct an impact and process
evaluation on the Irrigation Efficiency Rewards program. The recommendations made in
the process and impact evaluations were thoughtfully considered and implemented
throughout 2021.
The three main process evaluation recommendations and actions taken are described below:
1. Continue to develop program manual. The program manual is maintained by the
agriculture engineer and the program specialist in an electronic format located in a
shared file and accessible by ag reps and others. Continued edits and updates have been
made to the program manual.
2. Continue creating an electronic filing system for all project records. Menu projects have
an attachment option to place all supporting documents in an electronic file associated
with the project identification number.
3. Consider a more systematic method for reviewing vendor activity levels. The irrigation
vendor supply information for each project identification number has been added to the
program download worksheet. The program specialist will run a query each quarter and
share the information with the ag reps and/or irrigation supply companies. This is a way
to reward high participation and identify irrigation suppliers the company may want to
contact about increasing participation in the program.
The impact evaluation recommendations and actions taken are described below:
• Formalize data collection of system operating conditions for custom projects. A data
collection sheet has been developed and will be included in the application package as a
single place to store equipment information and operating parameters. The information
will include parameters for necessary components, such as nozzles, filters, or end guns.
The agriculture representatives will collect make, model and/or specification sheets of
critical components of the irrigation systems.
Irrigation Sector—Irrigation Efficiency Rewards
Page 148 Demand-Side Management 2021 Annual Report
• Streamline custom calculations. The baseline for an existing project is the energy used
by the existing irrigation system. This will continue to be the baseline because it
captures the behavior of irrigators and the equipment in use. The baseline for new
projects will be based on supplying an amount of water appropriate for each region.
For instance, the Canyon-West Region irrigation systems will have the capability to
deliver a larger volume of water per acre than a similar project in the South-East Region.
• Increase documentation for critical system components. A sheet that documents the
following has been added to the analysis of the installed energy efficiency project
information:
• Pump: brand, model, and impeller trim
• Sprinkler package description for center pivots and other irrigation systems
• Documentation of pipe type and size
• Specific section for product specification sheets
Marketing Activities
In addition to training, education, and marketing activities mentioned in the Irrigation Sector
Overview, the Idaho Power ag rep and program specialist worked one-on-one with irrigation
dealers and vendors who are key to the successful promotion of the program. In March 2021,
the agriculture representatives held three virtual workshops. The content was the same but
offered a morning, noon, and afternoon option on three different days so customers could
easily join. The virtual seminar focused on the Irrigation Efficiency Rewards program, Idaho
Power’s website, and self-help tools. The ag rep also visited each irrigation vendor in their area
to distribute new menu efficiency applications and explain the program changes and why.
Cost-Effectiveness
Idaho Power calculates cost-effectiveness using different savings and benefits assumptions and
measurements for the Custom Incentive Option and the Menu Incentive Option.
Each application under the Custom Incentive Option received by Idaho Power undergoes an
assessment to estimate the energy savings that will be achieved through a customer’s
participation in the program. On existing system upgrades, Idaho Power calculates the savings
of a project by determining what changes are made and comparing it to the service point’s
previous five years of electricity usage on a case-by-case basis. On new system installations,
the company uses standard practices as the baseline and determines the efficiency of the
applicant’s proposed project. Based on the specific equipment to be installed, the company
calculates the estimated post-installation energy consumption of the system. The company
verifies the completion of the system design through aerial photographs, maps, and field visits
Irrigation Sector—Irrigation Efficiency Rewards
Demand-Side Management 2021 Annual Report Page 149
to ensure the irrigation system is installed and used in the manner the applicant’s
documentation describes.
Each application under the Menu Incentive Option received by Idaho Power also undergoes an
assessment to ensure deemed savings are appropriate and reasonable. Payments are
calculated on a prescribed basis by measure. In some cases, the energy-savings estimates are
adjusted downward from deemed RTF savings to better reflect known information on how the
components are actually being used. For example, a half-circle rotation center pivot will save
half as much energy per sprinkler head as a full-circle rotation center pivot. All deemed savings
are based on seasonal operating hour assumptions by region. If a system’s usage history
indicates it has lower operating hours than the assumptions, like the example above, the
deemed savings are adjusted.
For three years the company has been working with the RTF and the irrigation subcommittee to
better understand the maintenance practices of program participants and evaluate the analysis
made by the RTF staff. The subcommittee developed an irrigation hardware survey, and in
February 2020, Idaho Power mailed the survey to irrigation customers. The company received a
23% response rate, and the RTF reviewed the survey results from Idaho Power, BPA, and
PacifiCorp. The results of the analysis were discussed at the March and April 2021 RTF
meetings. While measure savings did not change much, the survey results did support an
increase in the measure life from 4 to 5 years to 6 to 7 years. For four of the measures (wheel
line hubs, goosenecks with drop tube, cut and pipe press or weld repair, and new center pivot
base boot gaskets), the research showed little to no savings and the measures were removed
from the updated irrigation workbook. With no supported savings, Idaho Power will remove the
measures from the Menu offering in 2022.
The longer life improved the cost-effectiveness of the individual measures and allowed for the
company to increase the incentives offered for nozzles and wheel line levelers. However, now
that lower savings were confirmed for impact or rotating type sprinklers, the incentives needed
to be lowered to allow the measure to remain cost-effective. The changes to the measure
offerings were effective on December 31, 2021. Any invoice dated December 31, 2021, or
before and submitted within one year will be processed under the prior program measure
incentive list. For invoices with dates of January 1, 2022, and later, the updated measure list
and incentive levels changes are in effect.
The UCT and TRC for the program are 3.32 and 4.49, respectively. If the amount incurred for the
2021 evaluation was removed from the program’s cost-effectiveness, the UCT would be 3.34,
while the TRC would be 4.49.
Complete measure-level details for cost-effectiveness can be found in Supplement 1:
Cost-Effectiveness.

Evaluations
In 2020, Idaho Power contracted with a third party to conduct an impact and process
evaluation of the Irrigation Efficiency Rewards program. Idaho Power’s responses to evaluation
recommendations are listed in the Program Activities section above. A copy of the impact and
process evaluation is available in the Demand-Side Management 2020 Annual Report,
Supplement 2.
2022 Program and Marketing Strategies
Irrigation Efficiency Rewards program marketing plans typically include conducting at least six
customer-based irrigation workshops to promote energy efficiency, technical education, and
program understanding. Assuming COVID-19 policies allow, Idaho Power has committed to a
booth at the Idaho Irrigation Equipment Show & Conference, Western Ag Expo, Idaho Potato
Show, and the Southern Ag Expo. The focus of the booth material and conversations will be
around changes to the Irrigation Efficiency Rewards program and the recently approved
program changes to the Irrigation Peak Rewards program. Marketing the program to irrigation
supply companies will continue to be a priority, especially to help remind them of the program
changes and to distribute program information.
The company will promote the program in agriculturally focused editions of newspapers,
magazines, and radio ads. The radio ads will run during the winter/spring throughout the
company’s South-East region.

Description
Idaho Power’s Irrigation Peak Rewards program is a voluntary, demand response program
available to agricultural irrigation customers with metered service locations who have
participated in the past. Initiated in 2004, one of the purposes of the program is to minimize or
delay the need to build new supply-side resources.
The program pays irrigation customers a financial incentive to interrupt the operation of
specific irrigation pumps using one or more control devices and offers two interruption options:
Automatic Dispatch Option and Manual Dispatch Option. Automatic Dispatch Option pumps are
controlled by an AMI or cellular device that remotely turns off the pump(s). Manual Dispatch
Option pumps can participate if they have 1,000 cumulative hp or if Idaho Power has
determined the AMI or cellular technology will not function properly at that location. These
customers nominate a kW reduction and are compensated based on the actual load reduction
during the event.
Program event guidelines for both interruption options are listed below:
• June 15 to August 15 (excluding Sundays and holidays)
• Up to four hours per day between 1 and 9 p.m.
• Up to 15 hours per week
Irrigation Sector—Irrigation Peak Rewards
Page 152 Demand-Side Management 2021 Annual Report
• No more than 60 hours per season
• At least three events per season
The incentive structure consists of fixed and variable payments. The fixed incentive is $5.00 per
kW with an energy credit of $0.0076 per kWh. The demand (kW) credit is calculated by
multiplying the monthly billing kW by the demand-related incentive amount. The energy (kWh)
credit is calculated by multiplying the monthly billing kWh usage by the energy-related
incentive amount. The incentive is applied to monthly bills, and credits are prorated for periods
when reading/billing cycles do not align with the program season dates. An additional variable
credit of $0.148 per kWh applies to the fourth and subsequent events that occur between
1 p.m. and 8 p.m. The variable credit is increased to $0.198 per kWh when customers allow
Idaho Power to interrupt their pumps until 9 p.m.
Program rules allow customers to opt out of dispatch events up to five times per service point.
The first three opt outs incur a penalty of $5 per kW, while the remaining two incur a penalty of
$1 per kW based on the current month’s billing kW. The opt-out penalties will not exceed the
total credit that would have been paid with full participation.
Program Activities
In 2021, Idaho Power enrolled 2,235 (80.6%) of the eligible service points in its service area.
The total billing demand of participating service locations was 402.8 MW versus 400.5 MW in
2020. The total maximum potential reduction (capacity) for the program was 319.5 MW in 2021
versus 298 MW in 2020. The key factor impacting the higher maximum capacity was due to the
weather in 2021 that caused a higher percentage of enrolled pumps to be running on any given
day throughout the season.
Device failure identification and correction is an on-going effort pre-season and during season
that requires urgency due to the strict timeline of the program. The company used four
electrical contractors in 2021 to maintain, troubleshoot, repair, and exchange the AMI devices
and cellular devices for dispatching. In May 2021, the company replaced cell device locations
with AMI devices where possible. The cell-to-AMI device exchange was possible because
additional substations were equipped with the AMI hardware and software. The exchanges will
ensure a larger data set on the same technology platform, including analysis of hourly data.
The cell device does not allow for hourly monitoring. The removed cell devices were retired.
Table 21 shows the event performance by date and group. The total load reduction shown in
2021 is less than 2020 because not all participants were called on any of the event dates.
Not dispatching all four groups on any one day allowed the company to use the program more
frequently to match system needs. The program was dispatched for eight event days for a total
of 32 event hours and achieved a maximum demand reduction of 255.5 MW (at generation
level) on June 28, with only approximately two thirds of participants.

Marketing Activities
Idaho Power used virtual workshops, direct-mailings, and outreach calls to encourage past
participants to re-enroll in the program. The brochure, enrollment worksheet, and contact
worksheet were mailed to all eligible participants in March 2021. See the Irrigation Sector
Overview section for additional marketing activities.
Cost-Effectiveness
Idaho Power determines cost-effectiveness for the demand response programs under the
terms of IPUC Order No. 32923 and OPUC Order No. 13-482. Under the terms of the orders and
the settlement, all Idaho Power’s demand response programs were cost-effective for 2021.
The Irrigation Peak Rewards program was dispatched for 32 event hours and achieved a
maximum demand reduction of 255.5 MW. The total expense for 2021 was $7.0 million and
would have been approximately $9.7 million if the program was operated for the full 60 hours.
A complete description of cost-effectiveness results for Idaho Power’s demand response
programs is included in Supplement 1: Cost-Effectiveness.
Evaluations
Each year, Idaho Power produces an internal report of the Irrigation Peak Rewards program.
This report includes a load-reduction analysis, cost-effectiveness information, and program
changes. A breakdown of the load reduction for each event day and each event hour,
including line losses, is shown in Table 22.
In preparation for program changes and to gather customer feedback, the company conducted
a survey in early summer 2021 and held an informational webinar in the fall to share possible
program changes identified in preparing the 2021 IRP. See the complete survey results in
Supplement 2: Evaluation.
In addition, in 2021, Idaho Power engaged a third-party contractor to conduct an external
impact evaluation of the Irrigation Peak Rewards program. The evaluation found a
well-managed program with comprehensive support from Idaho Power staff. The evaluation
Irrigation Sector—Irrigation Peak Rewards
Page 154 Demand-Side Management 2021 Annual Report
calculated realization rates for the events between 76% and 91%, with an average event
realization rate of 88%.
The contractor recommended the continuation of the current load reduction calculation
methodology and calculating event realization rates as the difference between potential load
and achieved load reduction (potential load is defined as the load called in an event that is on
at the time of the event, and represents the maximum load reduction that can be expected
from a given event). The evaluation also recommended the continued improvement of program
infrastructure to reduce data and communication gaps as well as a recommendation to
streamline load calculations using computer code. See the complete analysis report in
Supplement 2: Evaluation.
Idaho Power will consider all recommendations made in the report, and any changes to the
program will be reported in the Demand-Side Management 2022 Annual Report.

2022 Program and Marketing Strategies
For the 2022 program season, Idaho Power will implement changes recently authorized by the
IPUC and OPUC to lengthen the season to September 15; change the event window to later in
the evening; increase the incentives; change the threshold from 3 to 4 events for when the
variable incentive is paid; modify the opt-out penalty for events after the first three; and open
enrollment to all agricultural irrigation customers.
Irrigation Peak Rewards enrollment packets will be sent to all irrigation customers whereas in
most recent years only the past participants received an enrollment packet. Each customer will
be sent a comprehensive packet containing an informational brochure, enrollment worksheet
and a contact worksheet. For all new pump sign-ups, a demand response unit will need to be
installed by a contracted electrician prior to June 15, 2022.
Idaho Power will have an informational booth at the local 2022 Ag Expos including Western,
Eastern, and Southern. The Irrigation Peak Rewards program will be the focus of in-person and
virtual irrigation workshops presented by Idaho Power ag reps in the spring of 2022. The ag

reps will continue to remind and inform customers and encourage program participation in
person and by phone.

Other Programs and Activities
Page 156 Demand-Side Management 2021 Annual Report
Other Programs and Activities
Idaho Power’s Internal Energy Efficiency Commitment
Renovation projects continued at the Idaho Power Corporate Headquarters (CHQ) in downtown
Boise, with a project to exchange the old T-12 parabolic lighting fixtures with LED fixtures on
floors six and eight. Remodels continued to incorporate energy efficiency measures, such as
lower partitions for better transfer of daylight, other lighting retrofits, and automated lighting
controls.
The CHQ building also participated in the Flex Peak Program again in 2021 and committed to
reduce up to 200 kW of electrical demand during events. Unlike other program participants,
Idaho Power does not receive any financial incentives for its participation.
Local Energy Efficiency Funds
The purpose of Local Energy Efficiency Funds (LEEF) is to provide modest funding for short-term
projects that do not fit within Idaho Power’s energy efficiency programs but provide a direct
benefit to the promotion or adoption of beneficial energy efficiency behaviors or activities.
Because Idaho Power has been modifying its existing programs and expanding programs over
the years to include as many cost-effective energy efficiency measures as possible for all
customers, there has been decreasing participation in the LEEF offering.
In 2021, Idaho Power received two LEEF applications. The first was related to a residential
central A/C and windows. The application was reviewed, and the products referenced in the
submittal were found to be standard, widely available products, and therefore not appropriate
for LEEF. A residential program specialist followed up with the applicant to provide information
on incentives currently available through Idaho Power’s H&CE Program.
The second LEEF application for funding related to LED lighting upgrades. The scope of work
looked to be eligible for lighting incentives in the Retrofit option of the C&I Energy Efficiency
program, so a commercial program specialist followed up with the applicant to investigate
further.
Market Transformation
Idaho Power’s energy efficiency programs and activities are gradually transforming markets by
changing customers’ knowledge, use, and application of energy-efficient technologies and
principles. The traditional market transformation definition is an effort to permanently change
the existing market for energy efficiency goods and services by engaging and influencing large
national companies to manufacture or supply more energy-efficient equipment. Through
market transformation activities, there is promotion of the adoption of energy-efficient
materials and practices before they are integrated into building codes or become standard
equipment. Idaho Power achieves market transformation savings primarily through its
Other Programs and Activities
Demand-Side Management 2021 Annual Report Page 157
participation in NEEA. Although, in 2020, Idaho Power and Avista did partner to engage with
another third party to explore potential opportunities for traditional market transformation
efforts that could benefit customers in both utilities’ service areas beyond what NEEA is
currently supporting. This engagement resulted in a market transformation pilot being started
in 2021 for DHPs in both Idaho Power’s and Avista’s service areas.
NEEA
Idaho Power has funded NEEA since its inception in 1997. NEEA’s role is to look to the future to
find emerging opportunities for energy efficiency and to create a path forward to make those
opportunities a reality in the region.
Pursuant to IPUC Order No. 34556, Idaho Power participates in NEEA with funding from the
Idaho Rider. The current NEEA contract is for the five years from 2020 to 2024. NEEA
categorizes the saving it achieves in five categories: total regional savings, baseline savings,
local program savings, net market effects, and co-created saving created by NEEA and its utility
funders working collaboratively. Of the 360 to 500 average megawatts (aMW) of savings
forecast for 2020 to 2024, NEEA expects 70 to 100 aMW to be net market effects, and 115 to
152 aMW will be co-created savings. The current contract commits Idaho Power to paying NEEA
$14.7 million, or approximately $2.9 million annually.
In 2021, Idaho Power participated in all NEEA committees and workgroups, including
representation on the Regional Portfolio Advisory Committee (RPAC) and the Board of
Directors. Idaho Power representatives participate in the RPAC, Cost-Effectiveness Advisory
Committee, Commercial Advisory Committee, RETAC and the Idaho Energy Code Collaborative.
The company also participated in NEEA’s initiatives, including the Residential Building Stock
Assessment (RBSA), Commercial Code Enhancement (CCE), SEM, Top-Tier Trade Ally (NXT
Level), and LLLC.
For the 2020 to 2024 funding cycle, NEEA and its funders have reorganized the “advisory”
committees. NEEA now has two coordinating committees: Products Coordinating Committee
and Integrated Systems Coordinating Committee. NEEA and its funders will form working
groups as needed in consultation with the RPAC. The RPAC will continue, as well as the
Cost-Effectiveness Advisory and the RETAC committees. The Idaho Energy Code Collaborative
will also remain intact.
NEEA performed several market progress evaluation reports (MPER) on various energy
efficiency efforts this year. In addition to the MPER, NEEA provides market research reports
through third-party contractors for energy efficiency initiatives throughout the Northwest.
Copies of these and other reports mentioned below are referenced in Supplement 2: Evaluation
and on NEEA’s website under Resources & Reports. For information about all committee and
workgroup activities, see the NEEA Activities information below.
Other Programs and Activities
Page 158 Demand-Side Management 2021 Annual Report
In 2022, Idaho Power will work with Avista and hire an independent third-party contractor to
conduct an evaluation of the savings NEEA claims and the allocation of those savings to
Idaho Power to determine if NEEA is a cost-effective resource, a prudent investment, and in the
best interest of Idaho Power customers.
NEEA Marketing
To support NEEA efforts, Idaho Power educated residential customers on HPWH and DHPs and
educated commercial customers and participating contractors on NXT Level Lighting Training
and LLLC.
Idaho Power promoted DHPs and HPWHs as part of its H&CE Program. Full details can be found
in the H&CE Program’s Marketing section.
Idaho Power participated in NEEA’s residential consumer awareness HPWH marketing
campaign from April 1 to May 30. The campaign ran throughout most areas of Oregon and
Washington, and in select areas in Idaho and Montana. The campaign creative pieces ran on
digital channels including Facebook, Instagram, YouTube, and display ads. Display ads are
shown to a person based on their demographics, related to online articles they viewed, or their
use of a particular mobile web page or app. The ads reached 95% of the intended audience and
viewers saw ads 17.8 times. The creative concept was intended to grab the viewers’ attention
and play off the idea that nobody really thinks about their water heater.
Idaho Power continued to encourage trade allies to take the NXT Level Lighting Training. Idaho
Power posted NXT Level Lighting Training information on its website and on LinkedIn in May.
To promote LLLC, Idaho Power continued using a link to an informational LLLC flyer on the main
Retrofits and Lighting web pages. The company also posted about LLLCs on LinkedIn in May.
NEEA Activities: All Sectors
Cost-Effectiveness Advisory Committee
The advisory group meets four times a year to review evaluation reports, cost-effectiveness,
and savings assumptions. One of the primary functions of the work group is to review all
savings assumptions updated since the previous reporting cycle. The committee also reviews
NEEA evaluation studies and data collection strategies and previews forthcoming research and
evaluations.
Idaho Energy Code Collaborative
Since 2005, the State of Idaho has been adopting a state-specific version of the IECC. The Idaho
Energy Code Collaborative was formed to assist the Idaho Building Code Board (IBCB) in the
vetting and evaluation of future versions of the IECC for the residential and commercial building
sectors. The group is comprised of individuals having diverse backgrounds in the building
industry and energy code development. Building energy code evaluations are presented by the
group at the IBCB public meetings. The group also educates the building community and
Other Programs and Activities
Demand-Side Management 2021 Annual Report Page 159
stakeholders to increase energy code knowledge and compliance. Idaho Power is an active
member. The work is facilitated by NEEA.
On January 1, 2021, new building and energy codes went into effect in the state of Idaho for
residential and commercial buildings. The Idaho Energy Code Collaborative provided statewide
resources throughout 2021 to builders and related stakeholders in support of the new codes.
The resources included monthly classroom-style online training sessions, a monthly technical
newsletter by email, and a robust website—IdahoEnergyCode.com. Idaho Power will continue
to participate in the Idaho Energy Code Collaborative.
Regional Emerging Technology Advisory Committee
Idaho Power participated in the RETAC, which met quarterly to review RETAC’s emerging
technology pipeline that was developed with assistance from the BPA, NEEA, and the
Northwest Power and Conservation Council (NWPCC) Seventh Power Plan. The emerging
technology pipeline held approximately 45 products and technologies at the end of 2021.
At each of the RETAC sessions, the complete pipeline was reviewed and prioritized by the
members. Throughout 2021, RETAC focused primarily on space- and water-heating products
and their technologies for residential and commercial markets. The technologies centered on
heat pumps. RETAC discussed the current state of the technologies and their associated gaps
and issues. In each RETAC session, the group discussed ways NEEA and the regional utilities
could help address those gaps and issues. This work will continue in 2022.
Regional Portfolio Advisory Committee
RPAC is responsible for overseeing NEEA’s market transformation programs and their
advancement through key milestones in the “Initiative Lifecycle.” RPAC members must reach a
full consent vote at selected milestones for a program to advance to the next stage. In 2018,
NEEA and RPAC formed an additional group called the RPAC Plus (RPAC+), which included
marketing subject matter experts to help coordinate NEEA’s marketing activities with those of
the funders. RPAC convenes quarterly meetings and adds other webinars as needed.
In 2021, RPAC conducted four quarterly meetings, all of which were virtual. Throughout 2021,
RPAC received updates of savings forecasts, portfolio priorities, and committee reports.
In the first regular quarterly meeting on February 24, NEEA staff went over the changes to
NEEA’s initiative life cycle and RPAC voting milestones. NEEA also presented a variable-speed
heat pump program concept and portfolio fit, which RPAC voted to advance into the program
development stage. NEEA staff updated the committee on carbon offsets, and research and
staff made the committee aware of the following emerging concepts for programs in the NEEA
portfolio: fan motor systems integration with the extended motor products program; thin
triple-windows; commercial heat pump water heaters for restaurants and hospitality industry;
and commercial rooftop HVAC systems with electric heating and cooling capabilities.
Other Programs and Activities
Page 160 Demand-Side Management 2021 Annual Report
On June 1, NEEA staff updated RPAC on recent developments and asked for concept
advancement votes on thin triple-pane windows, efficient commercial rooftop units, and fan
motor systems integration with the Extended Motor Products program.
At the September 1 meeting, NEEA gave an overview of the thin triple pane windows concept
and portfolio fit and RPAC supported advancing it to program development. NEEA also
presented their 2022 Operations Plan and timeline.
At the November 2 meeting, NEEA gave RPAC members an overview of the progress on the
Extended Motor Products for Pumps initiative and made the committee aware of NEEA’s latest
work developing a new television test procedure that more accurately reflects real-world
usage, its adoption by industry and the Environmental Protection Agency (EPA), and the
regional energy savings potential.
NEEA Activities: Residential
The company currently has representation on the NEEA Products Coordinating Committee and
the Integrated Systems Coordinating Committee. Meetings were held in each quarter of 2021
for both committees. These committees provide utilities with the opportunity to give
meaningful input into the design and implementation of NEEA programs, as well as to
productively engage with each other.
NEEA provides BetterBuiltNW online builder and contractor training and manages the regional
homes database, AXIS.
Residential Building Stock Assessment
NEEA began work on the RBSA in mid-2020. The RBSA is conducted approximately every five
years. Its purpose is to determine common attributes of residential homes and to develop a
profile of the existing residential buildings in the Northwest. The information is used by the
regional utilities and the NWPCC to determine load forecast and energy-savings potential in
the region.
Idaho Power participated in monthly work group meetings to discuss the study’s objectives,
framework, sampling design, and communication plan. Site visits in the region began at the end
of 2021 and will continue through 2022. For residential customers who choose to participate,
the third-party contractor will schedule a site visit with a field technician who collects
information on the home’s characteristics. A COVID-19 safety plan was developed and
approved by each utility prior to the start of the site visits.
It is anticipated that Idaho Power customers will be contacted for this study in mid-2022. A final
report will be available by the beginning of 2023.
Other Programs and Activities
Demand-Side Management 2021 Annual Report Page 161
NEEA Activities: Commercial/Industrial
NEEA continued to provide support for commercial and industrial energy efficiency activities in
Idaho in 2021, which included partial funding of the IDL for trainings and additional tasks.
Commercial Code Enhancement
NEEA facilitated regional webinars for the CCE initiative for new construction to discuss how
utilities can effectively align code changes and utility programs. The CCE is a NEEA initiative
comprised of people with varying backgrounds and levels of association with the building
construction industry. The group’s goal is to enable the continual advancement of commercial
construction and energy codes and identify opportunities to highlight above-code best
practices in local markets. This work will continue in 2022.
Top-Tier Trade Ally (NXT Level)
NEEA began transitioning long-term delivery of the Top Tier Trade Ally program to a third-party
contractor in 2021. One electrical contractor company in the Idaho Power service area achieved
NXT Level designation status in 2021. This addition would have resulted in four designated
companies; however, one company went out of business in 2021. NXT Level training in-person
classes were not offered in Idaho Power’s service area in 2021 due to the ongoing
COVID-19 pandemic.
Luminaire Level Lighting Controls
NEEA completed the LLLC MPER in 2021. The report centered on first-year tracking of market
progress indicators and other research objectives for purposes of gathering additional market
intelligence. NEEA reports the key findings in the study include the following:
• Northwest installation companies and design/specification companies have a high level
of awareness of LLLC.
• Customers who install LLLC see value in the flexibility of zoning and granularity of
control, although market barriers remain. These include higher first cost compared to
other types of controls, and a perception of LLLC as complex.
• The study recommends continued training of supply-chain market actors, especially on
the LLLC value proposition and best applications.
In 2021, NEEA assisted the IDL in Boise in installing an LLLC system in its office for LLLC training
and demonstration purposes. NEEA produced a variety of LLLC educational resources for use by
utilities and the public to promote LLLC. The library of educational materials is found at
BetterBricks.com.
Throughout 2021, NEEA partnered with utilities and professional associations to offer training
opportunities to further develop trade ally understanding and capabilities on the topic of
networked lighting controls (NLC) and LLLC systems. Idaho Power hosted the Making Controls

NEEA Funding
In 2020, Idaho Power and NEEA commenced a five-year agreement for the funding cycle of
2020 to 2024. Per this agreement, NEEA implements market transformation programs in the
company’s service area and Idaho Power is committed to fund NEEA based on a quarterly
estimate of expenses up to the five-year total direct funding amount of $14.7 million, or
approximately $2.9 million annually. Of this amount, in 2021, 100% was funded through the
Idaho and Oregon riders. Funding for the 2020 to 2024 five-year cycle was submitted to IPUC
for approval on October 21, 2019. On February 20, 2020, Idaho Power received IPUC Order No.
34556, supporting Idaho Power’s participation in NEEA from 2020 to 2024 with such
participation to be funded through the Idaho Rider and subject to a prudency review.
In 2021, Idaho Power paid $2,977,678 to NEEA: $2,828,794 from the Idaho Rider for the Idaho
jurisdiction and $148,884 from the Oregon Rider for the Oregon jurisdiction. Other expenses
associated with Idaho Power’s participation in NEEA activities, such as administration and
travel, were also paid from the Idaho and Oregon Riders.
Final NEEA savings for 2021 will be released later in the year. Preliminary estimates reported by
NEEA for 2021 indicate Idaho Power’s share of regional market transformation savings as
17,870 MWh. These savings are reported in two categories: 1) codes-related and standards-
related savings of 14,429 MWh (81%) and 2) non-codes-related and non-standards-related
savings of 3,440 MWh (19%).
In the Demand Side Management 2020 Annual Report, preliminary funding-share estimated
savings reported were 15,991 MWh. The final savings included in this report for 2020 final
funding-share NEEA savings are 17,614 MWh and include savings from code-related initiatives
as well as non-code related initiatives. Idaho Power relies on NEEA to report the energy savings
and other benefits of NEEA’s regional portfolio of initiatives. For further information about
NEEA, visit their website at neea.org.
Regional Technical Forum
The RTF is a technical advisory committee to the NWPCC, established in 1999 to develop
standards to verify and evaluate energy efficiency savings. Since 2004, Idaho Power has
supported the RTF by providing annual financial support, regularly attending monthly meetings,
participating in subcommittees, and sharing research and data beneficial to the forum’s efforts.
The forum is made up of both voting members and corresponding members from investor-
owned and public utilities, consultant firms, advocacy groups, ETO, and BPA, all with varied
expertise in engineering, evaluation, statistics, and program administration. The RTF advises the

NWPCC during the development and implementation of the regional power plan regarding the
following RTF charter items:
• Developing and maintaining a readily accessible list of eligible conservation resources,
including the estimated lifetime costs and savings associated with those resources and
the estimated regional power system value associated with those savings.
• Establishing a process for updating the list of eligible conservation resources as
technology and standard practices change, and an appeal process through which
utilities, trade allies, and customers can demonstrate that different savings and value
estimates should apply.
• Developing a set of protocols by which the savings and system value of conservation
resources should be estimated, with a process for applying the protocols to existing or
new measures.
• Assisting the NWPCC in assessing 1) the current performance, cost, and availability of
new conservation technologies and measures; 2) technology development trends; and
3) the effect of these trends on the future performance, cost, and availability of new
conservation resources.
• Tracking regional progress toward the achievement of the region’s conservation targets
by collecting and reporting regional research findings and energy savings annually.
The current agreement to sponsor the RTF extends through 2024. Under this agreement,
Idaho Power is the fourth largest RTF funder, at a rate of $713,300 for the five-year period. For
this funding cycle, gas utilities and the gas portion dual-fuel utilities are also funding the RTF.
When appropriate and when the work products are applicable to the climate zones and load
characteristics in Idaho Power’s service area, Idaho Power uses the savings estimates, measure
protocols, and supporting work documents provided by the RTF. In 2021, Idaho Power staff
participated in all RTF meetings and the RTF Policy Advisory Committee. At the end of 2021, an
Idaho Power analyst was selected to be a voting member of the RTF and will serve as an RTF
member for a three-year term effective January 2022.
Throughout the year, Idaho Power reviews any changes enacted by the RTF to savings, costs,
or parameters for existing and proposed measures. The company then determines how the
changes might be applicable to, or whether they impact, its programs and measures.
The company accounted for all implemented changes in planning and budgeting for 2022.

Customer Education and Marketing
REEEI produced one Energy Efficiency Guide in 2021, which was distributed primarily as an
insert in local newspapers. The summer-themed guide was published and distributed by
24 newspapers in Idaho Power’s service area the week of June 27. The guide focused on
information that would be useful to customers as they spend more time at home during the
COVID-19 pandemic, including a profile on a customer’s recent shed-turned-home-office
project, how to choose an electric lawnmower, induction cooking, and how customers can use
energy efficiency and other helpful programs to help Idaho Power reach its clean energy goal
and to lower customers’ own “energy footprint.”
Idaho Power promoted the guide on its homepage and on social media. The Idaho Statesman
published two ads encouraging readers to look for the guide. Digital ads on
idahostatesman.com included a homepage takeover on June 28 and July 1, as well as banner
ads that ran between June 20 and July 3, earning 150,000 impressions. Digital ads drove traffic
to the Energy Efficiency Guide on idahopower.com.
On its website, Idaho Power provides links to current seasonal guides and past guides.
REEEI distributed energy efficiency messages through a variety of other communication
methods in 2021. Idaho Power increased customer awareness of energy-saving ideas via
continued distribution of the fifth printing of the 96-page booklet 30 Simple Things You Can Do
to Save Energy, a joint publishing project between Idaho Power and The EarthWorks Group.
In 2021, the program distributed 1,160 copies directly to customers. This was accomplished
primarily by fulfilling direct web requests from customers, through energy advisors during in-
home visits, and in response to inquiries received by Idaho Power’s Customer Care Center.
Idaho Power continues to recognize that educated employees are effective advocates for
energy efficiency and Idaho Power’s energy efficiency programs. Idaho Power energy efficiency
program specialists connected with energy advisors and other employees from each of
Idaho Power’s geographical regions and the Customer Care Center to discuss educational
initiatives and answer questions about the company’s energy efficiency programs.
Due to COVID-19 restrictions, Idaho Power participated in a limited number of in-person
awareness events. Program specialists and EOEAs looked for virtual opportunities to continue
sharing messages regarding low-cost and no-cost energy-saving opportunities. In 2021, despite
the COVID-19 pandemic challenges, Idaho Power’s EOEAs connected with over 900 groups,
and gave over 350 presentations, sharing information, including energy-saving messages,
with audiences of all ages. Additionally, Idaho Power’s energy efficiency program specialists
responded with detailed answers to 216 customer questions about energy efficiency and
related topics received via Idaho Power’s website.

University of Idaho Integrated Design Lab
Idaho Power is a founding supporter of the IDL (idlboise.com), which is dedicated to the
development of high-performance, energy-efficient buildings in the Intermountain West.
Idaho Power has worked with the IDL since its inception in 2004 to educate the public about
how energy-efficient business practices benefit the business and the customer. In 2021,
Idaho Power entered into an agreement with the IDL to perform the tasks and services
described below.
Foundational Services
The goal of this task was to provide energy efficiency technical assistance and project-based
training to building industry professionals and customers. Requests for IDL involvement in
building projects are categorized into one of three types:
• Phase I projects are simple requests that can be addressed with minimal IDL time.
• Phase II projects are more complex requests that require more involvement and
resources from the lab.
• Phase III projects are significantly more complex and must be co-funded by
the customer.
The IDL provided technical assistance on 16 new projects in Idaho Power’s service area in 2021:
nine Phase I projects, three Phase II projects, two Phase III projects, and two additional projects
that are currently being evaluated to determine the scope of work. Eight of the projects were
on new buildings, seven were on existing buildings and one was not specified. The number of
projects stayed the same in 2021. The related report is in the IDL section of
Supplement 2: Evaluation.
Other Programs and Activities
Demand-Side Management 2021 Annual Report Page 169
Lunch & Learn
The goal of the Lunch & Learn task was to educate architects, engineers, and other design and
construction professionals about energy efficiency topics through a series of educational
lunch sessions.
In 2021, the IDL scheduled 14 technical training lunches that were conducted virtually due to
COVID-19 restrictions. All 14 sessions were available to the public; a total of 104 architects,
engineers, designers, project managers, and others attended.
The topics of the lunches (and the number performed of each) were: IAQ and Energy Efficiency
in Buildings (1); Daylight in Buildings: Getting the Details Right (1); The Architect’s Business Case
for Energy Performance Modeling (3); Luminaire Level Lighting Control (1); High-Performance
Classrooms (1); High Efficiency Heat Recovery (2); Dedicated Outdoor Air Systems (DOAS)
Integration (1); OpenStudio® Parametric Analysis Tool (1); LEED V4.1 Daylighting Credits (1);
ASHRAE 209 Energy Simulation Aided Design (1); and ASHRAE 36 High Performance Sequence
of Operations for HVAC Systems (1). The related report is in the IDL section of
Supplement 2: Evaluation.
Building Simulation Users Group
The goal of this task was to facilitate the Idaho BSUG, which is designed to improve the energy
efficiency related simulation skills of local design and engineering professionals.
In 2021, six BSUG sessions were hosted by the IDL. All six sessions were hosted virtually due to
COVID-19 restrictions. The sessions were attended by 154 professionals. Evaluation forms were
completed by attendees for each session. On a scale of 1 to 5, with 5 being “excellent” and 1
being “poor,” analyzing results from the first six questions, the average session rating was 4.42
for 2021. For the final question, “The content of the presentation was…” on a scale of 1 to 5,
with 1 being “too basic,” 3 being “just right,” and 5 being “too advanced,” the average session
rating was 3.53 for 2021.
Each presentation was archived for remote access anytime, along with general BSUG content
through the IDL website. The related report is in the IDL section of Supplement 2: Evaluation.
New Construction Verification
The goal of this task was to continue random post-project verification on 10% of the total
completed C&I Energy Efficiency Program New Construction projects. In 2021, the IDL
conducted 12 random on-site, post-project verifications. The purpose of this verification was to
confirm program guidelines and requirements, and help participants provide accurate
information regarding measure installations. See the New Construction option in the C&I
Energy Efficiency Program section for a summary of these activities. The complete verification
report is in the IDL section of Supplement 2: Evaluation.
Other Programs and Activities
Page 170 Demand-Side Management 2021 Annual Report
This task also included the desk review of all daylight photo-control incentives to improve the
quality of design and installation.
Energy Resource Library
The ERL gives customers access to resources for measuring and monitoring energy use on
various systems. The goal of this task was to operate and maintain the library, which includes a
web-based loan tracking system, and to teach customers how to use the resources in
the library.
The inventory of the ERL consists of over 900 individual pieces of equipment. In 2021, 10 new
tools were added to replace old data logging models, complete tool kits, and added accessories
for kits and other various tools. The tools and manuals are available at no cost to customers,
engineers, architects, and contractors in Idaho Power’s service area to aid in the evaluation of
energy efficiency projects and equipment they are considering. Due to COVID-19 restrictions,
a contactless pick-up and drop-off system is in place.
In 2021, nine of the 10 tool loan requests were completed by three unique users from
four locations, including three new users. The ERL web page recorded 1,483 visits in 2021.
The related report is in the IDL section of Supplement 2: Evaluation.
Energy Impacts of IAQ Devices
In 2021, the IDL examined the energy impacts of IAQ devices. The IDL used the energy modeling
software, EnergyPlus™, to estimate the effects of adding higher-rated filters, in-room High
Efficiency Particulate Air (HEPA) filters, ultraviolet irradiation, ionization devices, and increasing
the percentage of outdoor air. The IDL selected eight of the 16 prototype models from the
Pacific Northwest National Lab to simulate these operational adjustments. The IDL created a
one-page reference document outlining the major points and energy impacts of each IAQ
strategy for Idaho facility managers and owners. The related report for this task is in the IDL
section of Supplement 2: Evaluation.
2022 IDL Strategies
In 2022, the IDL will continue work on Foundational Services, Lunch & Learn sessions, BSUG,
New Construction Verifications, ERL, and two new tasks: Power Over Ethernet Demonstration
Project and LLLC Workshop Development.

a Levelized Costs are based on financial inputs from Idaho Power's 2017 IRP, and calculations include line-loss adjusted energy savings.
b The Program Administrator Cost is the cost incurred by Idaho Power to implement and manage a DSM program.
c The Total Resource Cost is the total expenditures for a DSM program from the point of view of Idaho Power and its customers as a whole.
d Demand response program reductions are reported with 9.7% peak loss assumptions.
1 Peak Demand is the peak performance of each respective program and not combined performance on the actual system peak hour.
2 Savings have been reduced by 5% to avoid double counting of savings in other energy efficiency programs.
