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 2023, Idaho Power achieved 139,683 megawatt-hours (MWh) or 15.9 average megawatts
(aMW) of incremental energy efficiency savings, including Northwest Energy Efficiency Alliance
(NEEA) estimated energy savings, which is greater than the economic technical achievable
potential included in the 2023 Integrated Resource Plan of 106,953 MWh or 12.2 aMW.
The 2023 savings represent enough energy to power approximately 12,253 average homes in
Idaho Power’s service area for one year.
The 2023 savings of 139,683 MWh, including the estimated savings from NEEA, decreased by
29,883 MWh—an 18% year-over-year decrease. The savings from Idaho Power’s energy
efficiency programs alone, excluding NEEA savings, were 115,769 MWh in 2023 and 145,440
MWh in 2022—a 20% year-over-year decrease. The decrease in savings can be attributed
almost entirely to three programs.
• The Commercial & Industrial (C&I) New Construction program option contributed over
half of the decline. While new construction activity in Idaho Power’s service area was up
in 2023 and the overall number of completed New Construction projects increased by
16%, the average savings per project decreased by 67%. This reduction was the result of
smaller projects with less savings achieved per project.
• C&I Retrofits savings also decreased, contributing over a quarter of the total portfolio
savings decline. While the number of projects was not lower in 2023, like New
Construction, project size was smaller and average savings per lighting project
decreased by 56%.
• Home Energy Reports contributed nearly 10% of the decline, due, in part, to naturally
occurring attrition of the treatment group, but also due to a milder weather year that
provided less savings potential per home.
In 2023, the company’s energy efficiency portfolio was cost-effective from both the utility cost
test (UCT) and the total resource cost (TRC) test perspectives with ratios of 2.06 and 1.51,
respectively. The portfolio was also cost-effective from the participant cost test (PCT) ratio,
which was 1.89.
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 2023. The total demand response capacity from

Executive Summary
Demand-Side Management 2023 Annual Report Page 2
the company’s programs was calculated to be approximately 316 megawatts (MW) with an
actual max load reduction of 240 MW.
Total expenditures from all funding sources of demand-side management (DSM) activities were
$42 million in 2023—$30.2 million from the Idaho Rider, $10.3 million from Idaho Power base
rates, and $1.5 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 the Energy Efficiency Guide, providing information on energy
efficiency equipment and ways to use energy wisely. Beginning in 2023, Idaho Power decided to
produce a new guide every nine months and changed the format to seasonal ‘themed’ guides.
The first fall-themed guide was published in October 2023.
Idaho Power participated in 144 events highlighting energy efficiency in 2023. Program
specialists and energy advisors shared information about programs and other energy-saving
ideas in an additional 709 presentations and trainings for audiences of all ages.

Figure 1. Example graphic from the 2023 Energy Efficiency Guide
In 2023, the Integrated Design Lab (IDL) conducted 20 technical training lunches. A total of
172 architects, engineers, designers, project managers, and others attended.
Idaho Power continued to provide training to its commercial and industrial customers in 2023,
delivering five technical training sessions to 159 individuals. An additional six live, online
technical training sessions were provided to industrial wastewater customers, attended by 74
participants.

Idaho Power provided seven in-person irrigation workshops and one conference seminar for
the Irrigation Efficiency Rewards and Irrigation Peak Rewards programs; a total of 369
customers attended.
The company sponsors significant customer educational outreach and awareness activities
promoting energy efficiency, 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 2023 Annual Report provides a review of the company’s DSM
activities and finances throughout 2023 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 630,000 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).

Funding Sources
Energy efficiency and demand response funding comes from multiple sources: Idaho Power
base rates, the Idaho and Oregon Energy Efficiency Riders (Riders), and the annual power cost
adjustment (PCA) in Idaho. Idaho incentives for the company’s demand response programs are
recovered through base rates and tracked through the annual PCA, while Oregon demand

response incentives are funded through the Oregon Rider. Total expenditures on DSM-related
activities from all funding sources were $42 million in 2023, as shown in Figure 3.

Figure 3. DSM expense history by program type, 2002–2023 (millions [$])
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
utility cost test (UCT), total resource cost (TRC) test, 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
program performance. In 2020, Idaho Power transitioned to using the UCT as the primary
cost-effectiveness test for energy efficiency resource planning in Idaho as directed by the Idaho
Public Utilities Commission (IPUC) in Order No. 34503. The company also calculates 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 Public
Utility Commission of Oregon’s (OPUC) 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

Demand-Side Management 2023 Annual Report Page 8
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 strives to work 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. The company believes this aligns with the
expectations of the IPUC and the OPUC.
As a result of IPUC Order No. 35336 (IPC-E-21-32) and the OPUC’s approval on February 8,
2022, of ADV 1355, Idaho Power determines cost-effectiveness for its demand response
programs using financial and alternate resource cost assumptions from each IRP. Details on the
cost-effectiveness assumptions and data are included in Supplement 1: Cost-Effectiveness.

and sector levels.
Energy Savings and Program Expenses
Energy Efficiency
Energy efficiency programs are available to all customer segments in Idaho Power’s service area
and focus on reducing energy use by targeting 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 energy efficiency contests,
the campus cohort, industrial energy efficiency cohort, 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
include programs for residential, commercial, industrial and irrigation new construction
(lost-opportunity savings), and retrofit applications. Idaho Power’s incentives and services are
offered to its residential, irrigation, industrial, large-commercial, small business, government,
and school customers to promote a wide range of energy-saving projects and activities.
Idaho Power devotes significant resources to maintain and improve its energy efficiency and
demand response programs. The 2023 total savings, including savings from the Northwest
Energy Efficiency Alliance (NEEA), were 139,683 MWh. 2023 savings decreased by 29,883 MWh
compared to the 2022 savings of 169,566 MWh—an 18% year-over-year decrease—
and represent enough energy to power approximately 12,253 average homes in Idaho Power’s
service area for one year. The savings from Idaho Power’s energy efficiency programs alone,
excluding NEEA savings, were 115,769 MWh in 2023 compared to 145,440 MWh in 2022—
an 18% year-over-year decrease. Savings and expenses are shown in Figure 4.
The 2023 savings results consisted of 24,394 MWh from the residential sector, 86,813 MWh
from the C&I sector, and 4,563 MWh from the irrigation sector. The C&I programs contributed

75% of the direct program savings. See Appendix 3 for a complete list of programs and
sector-level savings.
Figure 4. Annual energy savings and energy efficiency program expenses, 2002–2023
(MWh and millions [$])
Demand Response
The company estimates future capacity needs through the IRP planning process and plans
resources to mitigate predicted system deficits. The company strives to maintain capacity from
its demand response programs (A/C Cool Credit, Flex Peak Program, and Irrigation Peak
Rewards) consistent with needs identified through that planning process. The goal of demand
response at Idaho Power is to avoid or delay the need for new resources.
Idaho Power started its modern demand response programs in 2002 and as of 2023 had a
capacity of more than 8% of its all-time system peak load available to respond to a system peak
load event during the summer. Demand response is measured both by the actual demand
reduction in megawatts (MW) achieved during events, as well as the potential demand
reduction if all programs were used at full capacity.
In summer 2023, Idaho Power used all or portions of the programs on eight different days
between June 15 and September 15. The 2023 actual maximum non-coincidental load
reduction from all three programs was 240 MW (Figure 5). The total capacity for all three
programs was approximately 316 MW at the generation level. 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 (240 MW) is calculated using interval
meter data from participants. The maximum capacity (316 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

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. The 2023 Idaho Rider was 3.1% of base
rate revenues, pursuant to IPUC Order No. 34871. The 2023 Oregon Rider was 4% of base rate
revenues. Additionally, Idaho demand response program incentives were funded through base
rates and are tracked through the annual PCA mechanism. DSM expenses not funded through
the riders are included in Idaho Power’s ongoing operation and maintenance (O&M) costs.
Table 3 shows the total expenditures funded by the Idaho and Oregon Riders and Idaho Power
base rates resulting in total DSM expenditures of $41,979,473. The non-rider funding category
includes the company’s demand response incentives in Idaho, Easy Savings: Low-Income Energy

369 customers attended.
Marketing
Idaho Power used multi-channel marketing and public relations (PR) strategies in 2023 to
continually 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 content and messaging. 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
channels that help establish credibility and brand trust. Though the company has less

messaging 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 several
conferences and webinars in 2023, such as the quarterly E Source Marketing and
Communications Club.
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.
Social Media
Approximately 25% of the company’s social media content promoted energy efficiency in 2023.
Idaho Power regularly posted content encouraging energy efficiency behaviors,
program enrollment, and customer engagement on Facebook, X (formerly known as Twitter),
YouTube, Instagram, and LinkedIn. Social media content also showcased local businesses and
organizations that have benefitted from Idaho Power energy efficiency efforts. Idaho Power
used Facebook and X to help promote two energy efficiency customer sweepstakes giveaways,
encouraging customers to enter by leaving a comment about how they save energy in the
summer or winter.
Facebook, X, Instagram, and LinkedIn all remain as priority channels for engaging and
communicating directly with customers on energy efficiency tips and program offerings.
At the end of 2023, Idaho Power had approximately 28,000 followers on Facebook; 7,120 on X;
15,897 on LinkedIn; and 3,328 on Instagram.
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 2023,
the company’s energy efficiency homepage received 3,651 page views, the residential landing
page received 113,950 views, and the business and irrigation landing pages received
10,572 views. Idaho Power uses Google Analytics to analyze web activity. Google’s definition of

Public Relations
Idaho Power’s PR staff supported energy efficiency programs and activities through:
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 2023, the January and June issues of Connections were devoted to energy efficiency.
The January issue focused on education around demand response for residential,
commercial and industrial, and irrigation. The June edition featured summer energy-saving tips,
along with getting your home EE ready before going on vacation, and how much it costs to
power items in your home.
With another hot summer throughout the company’s service area, energy efficiency
information for staying cool during high temperatures was once again shared across the
company’s owned media channels and with regional media outlets. Social media messaging
included tips about how to save energy during high-use hours, which assists in reducing strain
on the company’s system.
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.
Customer Relationship Survey
A relationship survey measures the satisfaction of several aspects of a customer’s relationship
with Idaho Power, including energy efficiency, at a very high level. As such, the survey is not
intended to measure all aspects of the energy efficiency programs.
The 2023 Burke Customer Relationship 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 2023, 21.4% of the survey respondents across all sectors indicated they
participated in an Idaho Power energy efficiency program, and 93.8% were “very” or
“somewhat” satisfied with the program they participated in.
The sector-level results of the annual 2023 survey are discussed in the Residential,
C&I, and Irrigation Sector Overview sections of this report.

Evaluations
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. Third-party contracts are generally awarded
using a competitive bidding process managed by Idaho Power’s Corporate Services
department. 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.
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.
In 2023, Idaho Power contracted third-party evaluators to conduct program evaluations for
the following programs: Home Energy Audit program (impact and process evaluation),
Residential New Construction Program (impact evaluation), Shade Tree Project (impact
evaluation), Small Business Direct Install (impact evaluation), and Irrigation Efficiency Rewards
program (impact evaluation). A summary of the results of these evaluations is available in the
respective program sections.
External program administrators compiled program summary reports for the Student Energy
Efficiency Kits (SEEK) program and the HER program, and the company conducted internal
analyses for the A/C Cool Credit, Flex Peak, and Irrigation Peak Rewards programs.
An evaluation schedule and the final reports from evaluations, studies, and research completed

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, sponsorships,
Facebook ads, and boosted social posts aimed at a variety of customer demographics across the
service area.
New in 2023, the company retired the animated Joulie and Wattson cartoon advertising theme
and worked with a local agency to produce a campaign revolving around the theme of
“Good Energy.” Good Energy is centered around the idea that energy efficiency habits can help
“keep good energy in the room.” The new campaign helps the company creatively connect with
customers and share the idea that when you develop smart, efficient energy habits at home—
it just feels good! The company showcased this idea with a surprising cast of characters
and settings.
In addition to the new creative campaign, Idaho Power ran two new seasonally relevant
contests: The Flurry of Savings Winter Contest and the Sizzlin’ Summer Savings Contest.
The company also extended the Spring Campaign media buy into the hot summer months
(late July through early September) to keep energy-saving tips and Idaho Power programs top
of mind.
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.
Digital
During the spring campaign, web users were exposed to 2,755,031 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
4,611 times, resulting in a click-through rate of 0.17%. In the fall, the display ads received

3,897,704 impressions and 3,972 clicks, resulting in a click-through rate of 0.10%. Digital ads
also ran on BoiseDev.com throughout the year and received 1,399,668 impressions.
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 direct them to the appropriate energy efficiency web page. These ads received
365,852 impressions and 141,157 clicks throughout the year.
Owned Digital
Owned digital refers to digital assets that Idaho Power controls, including the My Account
online account management tool, mobile app, website, and digital company newsletter.
Idaho Power continued its effort with email communication in 2023. The company only
emails customers who have supplied their addresses for other business purposes (such as when
signing up for My Account or enrolling in paperless billing). Energy efficiency
promotional emails included heating and cooling tips, summer and winter contest promotion,
seasonal energy efficiency tips, and various program promotions. Detailed information can be
found in respective program sections.
In July, a pop-up ad ran in My Account—the online account management tool—providing a
quick energy-saving tip and link to the “Ways to Save” webpage. And throughout 2023,
energy-saving tips were featured in the Idaho Power mobile app, including pointers on heating
and cooling, thermostat adjustments, and plugging air leaks.
Streaming Audio: Podcasts and Music
Idaho Power continued with podcast and streaming music advertising as an awareness tactic in
2023, using 30-second audio ads, called “dynamic ads,” that are inserted into listener’s
programming if they reside in the company’s service area. The ads targeted customers by the
type of listener rather than being run on a specific show or music program. Types of podcast
shows that featured Idaho Power ads appealed to listeners such as green-living enthusiasts,
customers interested in home improvement/home repair, and homeowners age 18 and over.
The ads received 971,530 impressions in the spring with a listen through rate of 96.6% and the
fall ads received 680,917 impressions with a 99.05% listen through rate.
Television: Network and Streaming
Idaho Power used network television and Hulu advertising for the spring, summer, 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

Magazine. The spring and fall ads featured the quirky but lovable character, Tina,
and highlighted how she keeps “a wave of Good Energy flowing through her space by swapping
lightbulbs to LEDs.”
In 2023, 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 2024 Welcome Kits. The previous edition of the guide was included in
2022 Welcome Kits, provided to WAQC customers, and shared with customers who attended
events Idaho Power participated in.
Social Media
Three Facebook ads for the 2023 energy efficiency campaign received 90,664 impressions and
909 clicks per ad.
Throughout the year, Idaho Power used Facebook and X 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 2023, Idaho Power used several marketing 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 helped maintain energy efficiency program awareness throughout the year.
Tactics included a full-side bus wrap on a Pocatello Regional Transit bus in Eastern Idaho and a
full-side bus wrap on a Valley Regional Transit bus in the Treasure Valley. Billboards with EE
messaging were also placed around the Idaho Power service area: three in Western Idaho,
two in Eastern Idaho, one in Salmon, and two in South Central Idaho.
Additionally, 2023 included sports sponsorships; attendance at most service area events has
shown significant growth and is a great vehicle to share the EE message. Sports sponsorships
are particularly good at reaching residential customers because they associate EE messaging
with meaningful activities close to home. 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
where its energy efficiency ad would be displayed. The company’s energy efficiency ad was
shown 14,112 times during the 48-game season and the overall season attendance was
162,922. Two 15-second Idaho Power commercials were also shown during the Boise Hawks
Facebook Live Broadcast for all games.
A Boise State University (BSU) sponsorship was also part of the marketing strategy in 2023.
Energy efficiency messaging was featured at Albertsons Stadium during football games and

included digital concourse signage and a game co-sponsorship and table. The BSU basketball
sponsorship included a 30-second digital ribbon board that rotated throughout the game and a
“Good Energy Fan Cam” themed video board feature.
Sponsoring sporting events at Idaho State University (ISU) was also part of the marketing plan.
The sponsorship included digital energy efficiency ads on the ISU sports webpages that
garnered 105,000 impressions and 144 clicks. Idaho Power was also recognized during each
home football game by being the presenting sponsor of the “Idaho Power Helmet Shuffle
Game” shown on the big screen. The helmet shuffle game showcased an LED lightbulb hidden
under one of three football helmets. The helmets were shuffled around, and spectators had to
guess which helmet the LED was under. After the shuffle ended, a brief energy efficiency
message appeared on the screen.
Signage in the College of Southern Idaho basketball gym was used for energy efficiency
awareness as well as signage in the College of Idaho J.A. Albertson sports facility.
Seasonal Sweepstakes
In 2023, Idaho Power ran two seasonally focused energy efficiency sweepstakes—the Sizzlin’
Summer Savings Contest in August and the Flurry of Savings Giveaway in December.
Both sweepstakes aimed to maintain awareness about energy efficiency and the impact a
small change can make.
The summer sweepstakes ran August 11 through 21 and received 4,014 entries.
Customers were asked to comment—through social media or on the Idaho Power website—
with one way they save energy during the hot summer months. In return, participants were
entered to win a bundle of energy efficient outdoor items. The sweepstakes was promoted with
email messaging to 307,813 customers, and social media posts reached 24,909 customers,
receiving 75 engagements (likes, comments, shares). The sweepstakes was also promoted on
idahopower.com, through a pop-up ad in My Account, and featured in a News Brief to
media outlets.
The winter sweepstakes ran December 4 through 13 and received 5,492 entries.
Customers were asked to comment with one way they save energy in the cold winter
months. In return, participants were entered to win one of five 50-inch ENERGY STAR TVs.
The sweepstakes was promoted with email messaging to 313,256 customers and paid social
media posts reached 992 customers, receiving 216 post engagements. The sweepstakes was
also promoted on idahopower.com, through a pop-up ad in My Account, and featured in a
News Brief to media outlets.

Public Relations
Many of the company’s PR activities focused on the residential sector. Energy-saving tips in
News Briefs, TV segments, news releases, and Connections newsletter articles aim to promote
incentive programs and/or educate customers about behavioral or product changes they can
make to save energy in their homes.
See the Program Performance section and the C&I Sector Overview for more 2023 PR activities.
Customer Satisfaction
Idaho Power conducts the Burke Customer Relationship Survey each year. In 2023, on a scale of
zero to 10, residential survey respondents rated Idaho Power 7.88 regarding offering programs
to help customers save energy, and 7.91 related to providing customers with information on
how to save energy and money.
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 3,000 actively engaged members from
across Idaho Power’s service area. Idaho Power typically sends these members between six and
12 surveys per year. In 2023, Idaho Power included 13 energy efficiency messages with survey
invitations resulting in almost 14,000 touchpoints.
Recruitment for the Empowered Community is conducted annually to refresh the membership.
In February 2023, a direct email campaign was utilized, which resulted in 868 new members.
Almost 20% 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, 91.2% were “very” or
“somewhat” satisfied with the program.
See the individual program sections for program-specific customer satisfaction survey results.
Field Staff Activities
In 2023, Idaho Power’s residential and commercial energy advisors continued connecting with
customers through one-on-one and group meetings, presentations, and participating in events
to promote energy efficiency programs and offerings. The year also saw strong company
participation in the larger legacy events including regional home and garden shows,
STEM events, science fairs, career fairs, and even a BSU football game where Idaho Power was
able to garner hundreds of positive interactions with customers promoting energy efficiency.
Energy advisors continued to dedicate a larger percentage of their time to presentations and

community audiences.
Idaho Power continued to focus on the training and development of its energy advisors to
expand their knowledge, skills, and abilities related to energy efficiency programs,
innovative technologies, and serving customers. One of the highlights during the year was
an offering of a residential building science class by an external trainer contracted with NEEA
who shared insights and perspectives about windows, insulation, building envelope, appliances,
HVAC, and other residential measures. Idaho Power also held specific training classes on
empathy and effective communication, lighting, building envelope, HVAC, pumps, motors,

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 periods of high energy demand or for other system needs.
Customers’ A/C units are controlled using switches that communicate by powerline carrier
(PLC) using the same system used by Idaho Power’s advanced metering infrastructure (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 is 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.

These are the program event guidelines:
•June 15 through September 15 (excluding weekends and holidays)
•Up to four hours per day
•A maximum of 16 hours per week and 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 2023, about 18,714 customers participated in the program, with 213 in Oregon and 18,501 in
Idaho. Four cycling events occurred, and all were successfully deployed. Table 8 provides event
details. The cycling rate was 55% for two of the events and 50% for the other two events, and
the communication level exceeded 89% for each event. Idaho Power calculated the maximum
potential capacity in 2023 to be 25.3 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
1.37 kilowatt (kW) per participant. Customers receive a $5.00 incentive for each month of
participation between June 15 and September 15, resulting in a total annual incentive potential
of $20.00. The credits appear on their July through October bill statements.

Throughout 2023, Idaho Power representatives continued site visits to check switches and
equipment to improve communication levels. The company will continue work to ensure
devices associated with the program are communicating on an ongoing basis.
During the site visits, Idaho Power representatives placed informational stickers on devices that
included a safety warning regarding risk of electric shock if the sealed demand response unit
were opened, and a toll-free phone number customers could call with questions.
Marketing Activities
Idaho Power actively marketed the A/C Cool Credit program in 2023.
In the spring and throughout the summer, the company used phone calls, direct-mail letters,
and home visits (leaving door hangers for those not home) to recruit customers moving into

houses with existing switches and previous program participants who moved into new homes
without switches. Non-participating customers in homes with existing switches also received a
direct-mail letter, followed by a reminder email, offering a $25 gift card for signing up.
Radio ads were used to promote the program April through June. A 30-second ad ran on the
digital music streaming service, Spotify, and received 258,442 impressions. Radio ads totaling
861 also ran on stations throughout the service area; these spots reached 28.2% of the target
audience in Boise, 28.7% in Twin Falls, and 18.7% in Pocatello. The target audience was exposed
to the ad 5.4 times in Boise, 7 times in Twin Falls, and 6.2 times in Pocatello.
April through June, web users were exposed to 12,392,817 promotional 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 11,986 times, resulting in a click-through rate of 0.1%. A digital pop-up ad also ran on
My Account in May where 82,987 customers saw the pop-up, resulting in 3,081 clicks.
The company also sent recruitment letters to select customers who are homeowners and have
not participated previously. In total, over 45,000 direct-mail letters were sent. In addition to the
letters, follow-up emails (to customers with emails on file) were sent a few weeks after the
letter, reminding customers to sign up.
Participating customers received a thank you and credit reminder message on their summer
bills, and Idaho Power concluded the season by sending a thank-you postcard to participants.
Cost-Effectiveness
Idaho Power determines cost-effectiveness for its demand response programs using the
approved method for valuing demand response under IPUC Order No. 35336 and approved by
the OPUC on February 8, 2022, in Docket No. ADV 1355. Using financial and avoided cost
assumptions from the 2021 Integrated Resource Plan, the defined cost-effective threshold
for operating Idaho Power’s three demand response programs for the maximum allowable
60 hours is $84.57 per kW under the current program parameters.
The A/C Cool Credit program was dispatched for four events (totaling 14 event hours)
and achieved a maximum demand reduction of 19.6 MW with a maximum potential capacity of
25.3 MW. The total expense for 2023 was $1,987,623 and would have remained the same if the
program had been fully used for 60 hours because there are no additional variable incentives
paid for events called beyond the three minimum required events. However, this amount
includes $859,897 of switches, or demand response units (DRU), not used in 2023 that were
purchased in bulk for all three demand response programs’ future year needs. In 2024, this DRU
cost was moved out of the A/C Cool Credit account and put into an overhead account, and the
cost of the DRUs will be transferred to the appropriate program when utilized so that each

program will be expensed in the correct year. Using the total adjusted cost and the maximum
potential capacity results in a program cost of $29.93 per kW. This is less than the threshold,
and therefore, the program was cost-effective.
A complete description of the cost-effectiveness of Idaho Power’s demand response programs
is included in Supplement 1: Cost-Effectiveness.
Customer Satisfaction
In 2023, Idaho Power conducted an A/C Cool Credit non-participant survey to learn more
about barriers preventing people from participating in the program as well as to learn what
might motivate customers to participate. In November, an online survey was sent via email to
9,815 customers, with 501 responses. Additionally, a survey was mailed to 981 customers in
December, with 68 responses.
When asked why they do not participate in the program, 46% of respondents stated they
weren’t aware of the program, while 39% of respondents do not want their A/C interrupted,
and 34% of respondents indicated that the incentive is too low/not enough to motivate them
to participate.
Customers were asked how interested they are in participating in the A/C Cool Credit program.
Nearly 52% of respondents indicated they were very interested (11%) or somewhat interested
(40%) in participating in the program. Customers rated various components of the program and
were asked which components would motivate them to participate. Almost 43% of respondents
indicated that the “no cost to participate” was the most motivating factor while over 64% of
respondents did not find the “$5 monthly bill credit” motivating.
When asked why non-participant customers would not be interested in participating in the A/C
Cool Credit program, the respondents’ top three reasons were the concern about possible
changes to the indoor temperature during the event, followed by the length of the events,
and the $5 incentive amount.
Idaho Power will analyze these results and incorporate learnings into future outreach efforts to
increase enrollment.
Evaluations
In 2023, Idaho Power performed an internal review to evaluate the demand reduction over the
course of the four event days. The complete report on methods and results of the load
reduction analysis is available in Supplement 2: Evaluation. This section presents a summary of
the results.

The demand reduction was calculated by comparing the actual average load for participating
customers on each of the four event days to a corresponding baseline. Average hourly load
reduction by participant for each event and the maximum hourly load reduction achieved by
all participants for each event are shown in Table 9. In addition to calculating load reduction,
the number of households during each event that did not produce a statistically noticeable
demand reduction was quantified and reported as non-contributing households (Table 9).

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 provides
$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 in 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 CAP agencies—the Idaho Department of
Health and Welfare (IDHW), the 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 HVAC 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 energy efficiency information and energy-saving tips
with customers.
Program Activities
In March 2023, payments totaling $125,000 were provided to five CAP Agencies to cover the
cost of HVAC tune-ups, filters, and 30% administrative cost for four of the five agencies.
Agencies qualify applicants and if eligible, provide a coupon. The regional coupons show choices
for HVAC contractors who have signed guidelines with CAP Agencies for the program and
customers select a contractor. HVAC contractors visit customers and provide HVAC tune-up
services while educating customers about maintaining their HVAC system, how to change
filters, and saving energy in their homes. HVAC contractors bill the CAP Agency for their cost
with a maximum of $800 per coupon.
In 2023, 99 coupons were redeemed for HVAC tune-ups and either disposable furnace filters or
single washable filters. The cost associated with tune-ups and filters was $72,956. Four CAP
Agencies used 30% of their allotment for administrative services totaling $27,375.
Additionally, one agency’s 2023 administrative allotment of $33,750 was used to pay for work
completed by HVAC contractors in 2022.
In March 2023, the company sent helpful energy efficiency education materials to CAP Agencies
for regional HVAC contractors to share with customers.
Marketing Activities
The Easy Savings program is included under Savings for Your Home on the Idaho Power website
in the Income-Qualified Customers section.
Idaho Power provided HVAC tune-up coupons to CAP agencies throughout the service area,
where they share them with qualified customers. The company also promoted the coupon offer
on Facebook and X.

For the HVAC tune-up coupons redeemed in 2023, the program claimed approximately
109−545 kWh per home. The savings are a weighted average of single family, multifamily,
and manufactured home types from the 2022 energy efficiency potential study. The weighting
is derived from the 2023 housing types from both the WAQC and Weatherization Solutions for
Eligible Customers programs. The savings from the 2022 potential study includes tune-up
savings for cooling, space heating, and miscellaneous/ventilation. This is an increase over 2022
in which Idaho Power claimed approximately 61 kWh for the HVAC tune-ups. (The 61-kWh
value was derived from the 2020 potential study.)
2024 Plans
Each agency’s portion of the annual $125,000 payment will be made available to them in
quarter 1 of 2024 once committee meetings have been completed and contractor guidelines
are signed. As in previous years, agencies will begin 2024 with their portion of this payment
added to any unspent portion of the previous year’s payments.
Participating contractors will continue to discuss the importance of HVAC maintenance and
incorporate education about saving energy with coupon recipients. They will answer questions
about other ways to save energy in their homes as agreed upon for this low-income energy
efficiency educational program.

Description
Designated as a specific program in 2015, the Educational Distributions effort is administered
through the REEEI and seeks to use low- and no-cost channels to deliver energy efficiency items
with energy savings directly to customers. 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.

The curriculum, focusing on digital engagement, continues to be well received and SEEK
enrollments were strong. The vendor delivered 12,546 kits to 342 classrooms in 179 schools
within Idaho Power’s service area. This resulted in 2,876 MWh of savings.
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 2023, with the expiration of lighting savings due
to the Energy Independence and Security Act of 2007 (EISA) standards, the kit contents were
adjusted mid-year. From January through June, the kits contained four 1,100-lumen lightbulbs
and two nightlights. From July through December, each welcome kit recipient received two
800-lumen lightbulbs and two nightlights.
The company shipped approximately 30,000 Welcome Kits to customers in 2023—down slightly
from the quantity delivered in the previous three years. 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 use them to facilitate
energy efficiency conversations during customer visits. Nightlights have also become an
outstanding way to engage customers at events and presentations as energy advisors report
they are a sought-after item.
Student Energy Efficiency Kit Program
During the 2022–2023 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. If outside vendors were used to assist with distribution, the cost-effectiveness
calculations may include vendor-related charges.
The UCT and TRC for the program are 1.76 and 2.07, 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
The cost-effectiveness analysis for the SEEK offering was based on the savings by the kit
provided for the 2022–2023 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 69%. 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. Based on the
feedback received from the 2022–2023 school year, the savings for each kit averaged
approximately 229.22 kWh annually per household, and the program saved 2,875,850 kWh
annually. A copy of the report is included in Supplement 2: Evaluation.
Welcome Kits
With the implementation of EISA after June 30, 2023, Idaho Power claimed different savings for
the kits during the first and second half of the year.
For the first half of the year, Idaho Power used the RTF’s giveaway deemed savings value of
4.79 kWh for each of the four 1100-lumen LED lightbulb included in the kit. For the nightlight,
Idaho Power used the third-party evaluator’s calculated savings of 12 kWh per nightlight,
which was identified using survey data as part of a 2020 evaluation. For kits distributed after
June 30, 2023, Idaho Power did not claim savings for the LED lightbulbs; however, the company
continued to claim 12 kWh per nightlight included in the kit.
In 2023, the Welcome Kits were not fully cost-effective due to the erosion of lighting savings.
After consulting the EEAG in 2021, the decision was made to keep this educational offering,
but to only include the cost-effective portion associated with those energy savings in the
Educational Distribution program; the remainder of the kit costs are included in the REEEI
budget (see Other Program and Activities section).
2024 Plans
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 enhancements in LED technology (dusk-to-dawn sensors, etc.), promote the use of LED
nightlights as an energy-efficient, safe nighttime lighting option, and encourage in-home
adoption of other energy-saving behaviors.
Student Energy Efficiency Kit Program
Idaho Power will continue to offer the SEEK program. The company will work with the vendor
to implement process and curriculum enhancements based on suggestions received from
teachers, students, and parents.
The company will continue to leverage the positive relationships Idaho Power’s EOEAs have
within the schools to maintain program participation levels.

Description
The Energy Efficient Lighting program followed a markdown model that provided incentives
directly to manufacturers or retailers for more efficient lighting technology, with discounted
prices passed on to the customer at the point of purchase. The customer incentives helped buy
down the price of the qualified products to motivate customers to purchase efficient lighting
products over inefficient ones.
In 2021, the DOE announced they would be reinstating the EISA lighting standards. With input
and support from EEAG, the company decided to continue offering the lighting buydown
program through June 30, 2023. After that date, the DOE began enforcing federal EISA lighting
standards with financial penalties to those retailers that continued to sell inefficient lightbulbs
that did not meet the new 45 lumen-per-watt requirement. It was assumed that most retailers
would no longer sell inefficient lightbulbs after that date, negating the need for a program to
influence lighting purchasing decisions, so the program was closed on June 30, 2023.
Program Activities
To ensure there were no retailers receiving an incentive through the program when LEDs were
the only technology available, Idaho Power representatives visited participating retailers to
validate whether they still offered incandescent, halogen, or CFL lightbulbs in addition to the
RECEIVED

Page 50 Demand-Side Management 2023 Annual Report
LED lighting products. The intent of these visits was to confirm whether customers had options
when choosing their lightbulbs and whether the incentive would persuade them to purchase
the LED products. It was found that Walmart was early to stop offering non-LED lightbulbs; as a
result, they were removed from the program in April. The remaining retailers continued
participating though June.
In 2023, LED lightbulbs comprised 77% of the program’s sales for the year, a slight increase
from the 74% of lightbulb sales in 2022. LED fixtures comprised approximately 23% of overall
program sales.
In 2023, Idaho Power worked with 11 participating retailers, representing 85 individual store
locations in its service area. Of those participating retailers, 67% of sales were from grocery,
dollar, and mass-merchandise stores; 21% from do-it-yourself hardware stores; 11% from small
hardware stores; and 1% from membership clubs. Many rural sales came from the smaller
retailers that serve hard-to-reach customers. It was important to include several store types
across Idaho Power’s service area to ensure all customers have access to efficient
lighting options.

Marketing Activities
In 2023, the program contractor promoted discounts with special product placement and signs.

events to help discuss energy-efficient lighting with customers and to help them select the right
lightbulb for their needs.
Participating retailers were notified at the beginning of the year that the program would end by
July. In the months leading up to the end of the program, the program contractor visited each
participating retailer to remove any program POP from the store.
Cost-Effectiveness
The UCT and TRC ratios for the program are 1.69 and 1.51, respectively.
In 2023, Idaho Power used the same savings and assumptions source as was used in 2022.
While the RTF reviewed and updated the savings assumptions for residential lighting in
September 2022, the workbook accounted for the full enforcement of the EISA federal
lighting standards. Based on the market data, it was determined that the baseline would be
comprised almost entirely of LEDs. As a result, the RTF removed the retail and by-request
delivery channels.
For detailed cost-effectiveness assumptions, metrics, and sources, see Supplement 1:
Cost-Effectiveness.
2024 Plans
Although the lighting program was closed as of July 1, 2023, Idaho Power will continue to
monitor lighting technologies and products for future incentive or program opportunities.

the contracting company must first complete Idaho Power’s required orientation regarding
program guidelines and technical information on HVAC equipment.
A third-party contractor reviews, enters, and submits incentive applications for payment using a
program database portal developed by Idaho Power. The third-party contractor also provides
technical and program support to customers and their contractors and performs on- and
off-site verifications.
Program Activities
Program performance is substantially dependent on the contractors’ abilities to promote and
leverage the heat pump measures offered. Idaho Power developed participating contractors
currently in the program while adding 29 additional contractors in 2023. The program specialist
frequently engaged with contractors to discuss the program and provided technical assistance
and market information.
In February, the program updated the commissioning, controls, and sizing (CCS) requirements
for ducted air-source heat pump incentives as a result of updates made to this regional
measure by the Bonneville Power Administration (BPA). The updates were released to the
region in April 2022, and integrated into H&CE in February 2023. The changes involved adding
alternate methods to verify the system was installed correctly. For example, external static
pressure measurement can now be used to obtain supply airflow, and condenser temperature
split can be used to verify refrigerant charge. Individual CCS requirements were created for
both variable speed compressor systems and non-variable speed compressor systems.
In February, the program modified the manufacturing minimum energy efficiency rating
requirements for the ducted and ductless air-source heat pump and ducted central A/C
incentives to reflect the Department of Energy’s (DOE) minimum efficiency standards that
changed on January 1, 2023. The new standards result from changes the DOE made to the
product test procedure. (The test procedure is Appendix M1 contained in the US DOE 10 CRF
Part 430 Subpart B–Uniform Test Method for Measuring the Energy Consumption of Central Air
Conditioners and Heat Pumps.) The Appendix M1 test procedure is intended to create a more
realistic laboratory test environment to better simulate how these products would perform in a
real home. As a result, the program’s required minimum efficiency ratings were modified in
February 2023, including the Seasonal Energy Efficiency Ratio (SEER), the Energy Efficiency
Ratio (EER), and the Heating Seasonal Performance Factor (HSPF). Prior to the test procedure
changes, the product published ratings were called SEER, EER, and HSPF. The new ratings are
referred to as SEER2, EER2, and HSPF2. The modified test procedures are more stringent and
result in the expected lower test result numbers.
In November, the company implemented nine changes to the program which involved seven
measures. Four measures received modified incentive amounts in response to ongoing

Marketing Activities
Idaho Power used multiple marketing tactics for its H&CE Program promotion in 2023.
In February, the company emailed information about the H&CE Program to approximately
298,195 residential customers. The promotion was opened by over 152,926 customers and
received approximately 4,884 clicks to the H&CE Program website. Idaho Power also sent an
email promotion in October to 310,753 residential customers; the email was opened by
154,593 customers and received 4,001 clicks to the web page.
Program information was included in the August edition of the company’s monthly customer
e-newsletter, “The Current.” The e-newsletter also mentioned the smart thermostat incentive
in an article about reducing energy use. The program was featured as a clickable digital ad in
The Current in October. Customers who clicked the ad were directed to the H&CE Program
website. A social media post referring to the program and federal tax credits ran in October.
Program information was also included in energy efficiency collateral mailed in the new
customer Welcome Kits. Additionally, the program was featured on Idaho Power’s website
homepage in March.
In March and April, the program was promoted as a clickable ad on the company’s e-bill—
a version of the bill that is emailed to customers who prefer to receive their bill digitally.
Customers who clicked on the ad were directed to the heating and cooling web page.

Two inserts were sent in bills to promote the program—once in April to 298,300 customers and
once in October to 342,249 customers. The October insert also included information on
applicable federal tax credits—which could help customers save more when combined with the
Idaho Power incentive. The program and applicable tax credits were also promoted on social
media.
Additionally, the program “tech sheets” were updated in 2023 to reflect program incentive
changes. The sheets are used as a leave-behind collateral piece with customers who are
interested about more program information.
Cost-Effectiveness
In 2023, the H&CE Program had a UCT of 0.94 and TRC of 0.40.
Overall, while participation decreased slightly from 1,080 participants in 2022 to
1,035 participants in 2023, the total savings decreased by 270,191 year over year.
The decrease in overall savings is largely due to updates to various savings assumptions.
The RTF is the source of most measure savings assumptions within the program and many
savings assumptions changed between 2022 and 2023.
Smart thermostats make up 45% of the total program participation and 14% of the total
savings. With the RTF workbook version 3.1, the per unit savings declined by between
24 to 65% compared to the workbook version 1.3 which was used in 2022. The RTF reviewed
and updated the savings assumptions for smart thermostats in January 2022. The RTF reviewed
recent program evaluations and NEEA research which found electric savings to be inconsistent
and variable. The RTF moved forward with applying the evaluation results and updated the
measure specifications and research strategy.
Air-source heat pumps made up 17% of the total program participation and 44% of the total
savings. On average, the per unit savings declined by nearly 12% over 2022. This was largely
due to the removal of CCS adder that had been included with the ASHP savings. The RTF
deactivated the workbook in 2020. This was due to the uncertainty around the savings and the
interaction between the ASHP and new thermostats. At the time, Idaho Power continued to use
the savings for 2021 and 2022 as it awaited results of the program evaluation. While the
evaluation found that most projects did not meet all of the performance tested comfort system
(PTCS) requirements, the projects did meet most of the requirements. The evaluators believed
“that these projects still display significant potential for savings toward additional control and
saving activities implemented by the program.” As a result, Idaho Power still requires the
installers to comply with BPA’s updated PTCS requirements and will continue to monitor the
impacts of proper CCS on ASHP savings. Additionally, CCS savings could not be used in
conjunction with smart thermostat savings and the new smart thermostat workbook version

Demand-Side Management 2023 Annual Report Page 57
3.1 included a heat pump optimization specification. The decision was made to remove CCS
savings in 2023 since the updated thermostat savings would have accounted for the resistance
heat optimization. Finally, the newest ASHP workbook version 7.3, which the program is using
as of November 2023, factored in recent evaluation and research, including Idaho Power’s
evaluation, when updating the ASHP savings assumptions. Because the evaluations and
research included programs that required CCS, some CCS savings are embedded in the
ASHP numbers.
Ductless heat pumps made up 17% of the program participation and 19% of the total savings.
While the savings assumptions did not change year over year, the average savings per unit
declined by nearly 16%. Savings are dependent on location. Heating zone 1 and cooling zone 3
have the highest savings at 1,945 kWh per DHP. In 2023, 25% of participants lived in this
heating and cooling zone compared to 43% in 2022.
Finally, in regard to the increase in TRC cost-effectiveness, the calculation includes tax credits
for the participant. As part of the Inflation Reduction Act of 2022, tax credits are available for
ASHP, open-loop heat pumps, ground-source heat pumps, ductless heat pumps, heat pump
water heaters, and central A/Cs that meet certain efficiency standards. These tax credits range
from $600 to $9,000. The inclusion of the tax credit offsets the participants costs used in the
TRC calculation.
In November 2023, Idaho Power modified the program based on the updated savings and
analyzed with the newest DSM avoided costs from the 2023 IRP. With these changes, the
program is expected to be cost-effective going forward.
For detailed information about the cost-effectiveness savings, sources, calculations,
and assumptions, see Supplement 1: Cost-Effectiveness.
2024 Plans
Idaho Power’s primary goal in 2024 is to develop contractors currently in the program with a
focus on the 29 new contractors added in 2023. The program specialist will frequently interact
with the contractors and continue to provide program guidance and full technical support to
assist them in meeting program requirements and further their product knowledge.
This 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.
The 2024 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 with thermostatic shower valve
•Pipe insulation from the water heater to the home wall (approximately 3 feet)
•Tier 2 Advanced Power Strip (once stock is depleted [anticipated by quarter 4 of 2024],
power strips will no longer be a direct-install measure)
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.

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 individual, separate heating systems 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 $400
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.
Program Activities
Four home performance specialist companies served the program in 2023 and completed
337 energy audits. The number and percentage of audited homes per heating fuel type
are listed in Table 13.
Table 13. Number and percentage of audited homes per heating fuel type

Quality assurance (QA) remained suspended during 2023 as the waitlist of projects in the
pipeline remained the priority. The survey format for QA will be explored and QA will resume
in 2024.
Marketing Activities
To allow contractors to work through the waitlist of interested customers created when
in-home work was suspended in 2020 and 2021, Home Energy Audit marketing was limited
in 2023.

Although working through the waitlist was a top priority, an email was sent to 5,000 residential
customers in December to help maintain program visibility. Those 5,000 customers were
prioritized because they had residential home addresses in Ada or Canyon counties (near the
auditor) and had not previously been enrolled for an audit. Website updates were made
throughout the year to keep program details up to date. The look of the leave-behind folder
was updated with the “Good Energy” theme, and new flyers—including a My Account and EE
Program Summary piece—were also included. The program was mentioned in various articles
in the Fall Energy Efficiency Guide.
Customers who enrolled in Home Energy Audit throughout the year were asked where they
heard about the program. Responses included the following: information in the mail, 19.38%;
family member or friend, 12.40%; Idaho Power employee, 16.02%; social media, 3.10%; other,
48.58%; did not reply, 0.52%.
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 use the traditional cost-effectiveness tests.
However, the increase in the program’s overall levelized costs from 2022 to 2023 is largely due
to the inclusion of evaluation expenses and the decrease in savings potential. If evaluation
expenses were removed from the program’s costs, the 2023 utility levelized costs and total
resource levelized costs would be $1.728 and $2.141, respectively.
With the implementation of EISA after June 30, 2023, Idaho Power claimed different savings for
the LED bulbs for the first and second half of the year. For the first half of the year Idaho Power
used the RTF LED workbook version 9.3 savings for direct-install lightbulbs, which range from
4.73 to 14.21 kWh per year. For installs that occurred after June 30, 2023, the RTF LED
workbook version 11.1 was the source for all savings assumptions with savings that range from
1.99 to 2.74 kWh per year.
In Idaho Power’s 2022 Energy Efficiency Potential Study, it is estimated that pipe wraps save
approximately 18 kWh per foot annually. Previously, the pipe wrap savings were capped at
three feet per home regardless of the number of feet installed in the home. As recommended
by the evaluators, the cap was removed. Savings for pipe wrap are counted for homes with
electric water heaters. Since pipe wrap is installed in three-foot increments, the savings ranged
from 55 to 111 kWh per home.
The integrated 1.75 gallons per minute (gpm) high-efficiency showerheads with thermostatic
shower valves were installed in four homes. The savings are approximately 50 kWh per year.

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
included in the sector and portfolio cost-effectiveness. Idaho Power also converted the 18 kWh
per foot of pipe wrap savings to 1.89 therms and those gas savings are included in the sector
and portfolio cost-effectiveness as non-energy benefits.
Evaluations
Impact and process evaluations for the Home Energy Audit program were performed by a
third-party contractor in program year 2022. The evaluators verified 28,801 kWh savings at a
102% realization rate for the program. The evaluators verified savings and assumptions using a
deemed savings approach for the measures included in the program in addition to verifying
in-service rates. The evaluators reviewed all tracking data as well as the project data and
confirmed that project-level measure details were tracked accurately and that the RTF
equations and assumptions were utilized correctly to calculate expected savings.
Listed below are the evaluators’ recommendations (in italics) followed by
Idaho Power’s response.
The evaluators recommend updating the unit energy savings value for this measure to correct
manual entry errors. The savings values having been updated in calculating the program’s
savings for 2023. However, in mid-2023, federal lighting standards increased due to the full
enforcement of the EISA, thus the savings assumptions were updated for installations that
occurred after July 1.
The evaluators recommend that Idaho Power continue to use the in-service rates assumed by
the RTF for this program in future cycles. For the measures in which Idaho Power uses the
savings assumptions from the RTF, Idaho Power will continue to use the in-service rates that
are factored into the savings value.
The evaluators recommend that Idaho Power start tracking whether HEA participants enroll
in other Idaho Power offerings within one to two years of completing the energy audit.
Idaho Power will explore reporting options to link home energy audits with participation in
other programs.
The evaluators recommend program staff consider reiterating the importance of follow-up
calls to the auditors. Program staff will reiterate the importance of the follow-up call with
program auditors.
The evaluators recommend that IPC provide additional program information to auditors,
so they better understand the program offerings available to customers. The evaluators also
recommend program staff more strongly encourage auditors to share additional program
offering information to customers. Idaho Power will continue to work with the auditors to

ensure they are familiar with Idaho Power programs and encourage them to discuss and share
program information with customers.
Although the program currently aims to remain contractor neutral, the evaluators
recommend allowing the auditors to provide customers recommendations for contractors
based on recommended energy efficiency upgrades. The evaluators also recommend Idaho
Power provide auditors training regarding how to appropriately recommend contractors
related to the suggested energy efficiency improvements made to the customer. Idaho Power
does not maintain a qualified contractor list nor endorse specific contractors. Without the
ability to monitor and rate contractors based on their skills, abilities, performance, pricing,
customer service, and longevity, the company could bias customers to select a contractor that
does not meet their needs or bias customers away from acceptable companies that are not
known to Idaho Power. Therefore, the company has chosen not to implement this
recommendation.
The Evaluators recommend that Idaho Power incorporate house vintage to target homes for
participation in the program that are more than 10 to 15 years old to target for home energy
audits. Idaho Power will explore using house vintage as a parameter when creating targeted
marketing lists.
The evaluators recommend reassessing door sweeps for inclusion. Idaho Power will
re-evaluate the option to add door sweeps to the program.
The evaluators recommend that Idaho Power include Snugg Pro as part of the regular training
sessions with auditors and provide additional guidance and clarification on quality control
practices and outputs from the software. Idaho Power will work with the SNUGG Pro software
developers to explore the opportunity for an in-person or online auditor training in 2024.
The evaluators recommend that Idaho Power require each home energy auditor to be
certified by the DOE certification programs for the Energy Efficient Home Improvement Credit
(Section 25C) and provide the written home energy audit report to customers with the
required information (qualified home energy auditor’s name and EIN, an attestation that the
qualified home energy auditor is certified by a qualified certification program, and the name
of such qualified certification program). Idaho Power will verify the IRA auditor certification
requirements and determine the feasibility of requiring program auditors to be certified by the
Department of Energy certification programs for the Energy Efficient Home Improvement Credit
(Section 25). Idaho Power will also pursue adding the EIN number to the current audit report
with the auditing software developers.

Description
The objective of the HER Program is to encourage customers to engage with their home’s
electricity use with a goal 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. Idaho Power works with a third-party contractor to operate the program.
There are two groups of active participants in the HER program: pilot participants and
participants added to the program in 2020. All active participants receive periodic Home Energy
Reports with information about how their homes’ energy use compares with similar homes. The
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 random process.
Program Activities
In 2023, all HER Program participants received quarterly reports in the months of February,
May, August, and November.

In addition to showing participants how their energy compared relative to similar homes,
each quarterly report delivered in 2023 addressed weather-related usage, as appropriate, along
with other tips related to appliances, lighting, and always-on devices. The February reports
focused on either ways to reduce electric water heating costs or appliance tips. In May,
customers with significant A/C use during the previous summer received tips to reduce
upcoming cooling bills while others learned how to maximize the use of day lighting in their
homes. The August reports were, once again, segmented between participants with significant
A/C use and those whose energy use was less affected by weather. In November, customers
with electric space heating received information regarding their previous winter’s use along
with heating tips while the remaining customers received general tips.
Idaho Power continued to send email reports (eHERs), in addition to paper reports, to
participants for whom Idaho Power had an email address on file. A total of 559,032 reports
were delivered in 2023 (Table 14).

In 2023, as in 2022, 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 participants added to the program in 2020
saw slight decreases in both their savings percentage and kWh savings per customer, dropping
from 1.35% to 1.28% and from 206.61 kWh to 187.89 kWh, respectively. Overall, the active
participants used an average of 178.92 fewer kWh per home than their control group
counterparts. When viewed in aggregate, the estimated savings for all program participants
was about 1.24% below their respective control groups, for a total reported savings of
17,467,444 kWh. The small group of customers who received their last report in February of
2020 continued to demonstrate persistent savings. With residual savings included, total 2023
reported program savings came to 17,737,130 kWh. With the exception of one small outlier
group, program participants achieved savings between 74 and 249 kWh annually per home.
Idaho Power’s customer solutions advisors responded to 385 HER Program-related phone calls
during the year. Given that 559,032 reports were delivered, this represents a call rate of just

the reports cannot be requested by customers, therefore the program is not marketed.
The Home Energy Reports (as well as Account Alerts and My Account) were used to cross-
market Idaho Power’s other energy efficiency programs (i.e., Home Energy Audits, H&CE
Program, and Energy Efficient Lighting).

Cost-Effectiveness
HER Program 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 HER Program savings of 17,737,130 kWh by 0.44% to report savings of 17,659,087 kWh.
This percentage was recommended by evaluators during the 2022 impact evaluation. Based on
the reported savings of 17,659 MWh, the UCT and TRC for the program are 1.32 and 1.51,
respectively, for 2023. The cost-effectiveness is based on the one-year life of the program. The
program’s one-year life cost-effectiveness improved due to the application of the DSM avoided
costs from the 2021 Integrated Resource Plan.
For more detailed information about the cost-effectiveness savings and assumptions, see
Supplement 1: Cost-Effectiveness.
2024 Plans
In 2024, Idaho Power plans to work with the new contractor to maintain or enhance the HER
cadence and enrich the customer experience for current participants. In addition, the pool of
existing residential non-participating customers will be reviewed to see if there are enough new
eligible participants to add a new wave of customers receiving reports. Idaho Power will work
with the new contractor to improve the two-way flow of data between the contractor and
Idaho Power in order to tighten the feedback loop and shorten the timeframe for implementing
program improvements.

Description
Idaho Power offers free energy audits for customers with electrically heated 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. The customer receives an estimate
of costs and savings for recommended energy-efficient measures. Customers may choose
either a cash incentive or a 6.5%-interest loan for a portion of the costs for
weatherization measures.
Program Activities
Three audits were completed in 2023. None of the audit customers chose to pursue energy
efficiency upgrades.
Marketing Activities
In October, Idaho Power sent 10,124 Oregon residential customers an informational brochure
about energy audits and home weatherization financing.

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, NEEM-certified,
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.
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 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 2023, for each home sold under this program, the residential customer incentive was $1,000
and the sales staff incentive was $200. Idaho Power paid 79 incentives on new manufactured
homes, which accounted for 214,236 annual kWh savings. This included 75 homes sited in
Idaho and four sited in Oregon. Of the 79 homes in the program, 22 were NEEM+, 56 were
ENERGY STAR, and 1 was Eco-Rated.
Marketing Activities
Idaho Power continued to support manufactured home dealerships by providing them with
program marketing collateral.
In April and November, Idaho Power promoted the Rebate Advantage program with a bill insert
sent to 298,300 and 298,088 customers, respectively. The insert was updated with the “Good
Energy” style and had information about potential energy and cost savings and referred
customers to the program website.
In November, the company sent an email promotion to 46,000 customers. The email received
17,815 opens and 148 unique clicks.
Cost-Effectiveness
The UCT and TRC for the program are 0.98 and 0.93, respectively.
In 2023, Idaho Power used the same savings and assumptions source used in 2022. The decline
in UCT cost-effectiveness between 2022 and 2023 is largely due to the application of the DSM
avoided costs from the 2021 IRP. On average, the benefit value declined 22% between the 2019
Second Amended IRP and the 2021 IRP. However, the program is expected to be cost-effective
in 2024 with the application of the DSM avoided costs from the 2023 IRP. All things remaining
equal, the benefit value increases by approximately 12% between the 2021 IRP and the 2023
IRP. Regarding the increase in TRC cost-effectiveness, the calculation includes tax credits for the
participant. As part of the Inflation Reduction Act of 2022, Section 45L Tax Credit for Energy
Efficient New Homes was updated and extended. For certified manufactured homes meeting
the most recent ENERGY STAR Manufactured New Home program requirements, a $2,500 tax
credit is available to the homebuilder. The inclusion of the tax credit offsets the participants’
costs used in the TRC calculation.

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 calculate the energy savings and
the percent above code information needed to certify the home.
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 2023, the company paid incentives for 64 newly constructed energy-efficient homes in Idaho,
accounting for 234,945 kWh of energy savings. An additional 130 homes remained in the queue
for verification by the program QA provider, having been temporarily delayed as the QA
provider and program rater worked through reporting requirements.
Marketing Activities
Idaho Power participated in the Snake River Valley Building Contractors Association (SRVBCA)
and the Building Contractors Association of Southwestern Idaho (BCASWI) builders’ expos and
sent marketing materials to the winter and fall Idaho Building Contractors Association (IBCA)
Board Meetings.
Idaho Power supported 2023 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
BCASWI, the SRVBCA, and the Building Contractors Association of Southeast Idaho (BCASEI).
The company sent a bill insert to 287,399 Idaho customers in May to promote the program.
The program brochure was left at the City of Boise permitting office as a hard-copy handout.
Cost-Effectiveness
The savings for the 64 energy-modeled homes averaged approximately 3,671 kWh per home
depending on which efficiency upgrades were included, an increase over the average
energy-modeled savings of 3,097 kWh per home in 2022. The increase was largely due to two
factors: a higher percentage of homes built in 2023 (61%) were built 20% or more above code,
relative to homes built in 2022 (30%); and a higher percentage of homes built in 2023 were
detached single-family homes (23%), relative to homes built in 2022 (8%). Single-family homes
tend to have large savings when compared to attached townhomes.

While savings are custom calculated for each of the 64 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 proxy for the incremental costs and non-energy benefits.
The UCT and TRC for the program are 1.05 and 1.25, respectively. The decline in the UCT
cost-effectiveness between 2022 and 2023 is largely due to the application of the DSM avoided
costs from the 2021 IRP. On average, the benefit value declined 13% between the 2019 Second
Amended IRP and the 2021 IRP. Regarding the increase in TRC cost-effectiveness, the
calculation includes tax credits for the participant. As part of the Inflation Reduction Act of
2022, Section 45L Tax Credit for Energy Efficient New Homes was updated and extended.
Finally, if the amount incurred for the 2023 evaluation was removed from the program’s cost-
effectiveness, the UCT would be 1.23 and the TRC would be 1.42.
For detailed information for all measures within the Rebate Advantage program, see
Supplement 1: Cost-Effectiveness.
Evaluations
The Residential New Construction Program underwent a third-party impact evaluation for
program year 2023. The complete evaluation, including all evaluator recommendations can be
found in Supplement 2: Evaluation.
Recommendations from the evaluators are listed below (in italics) followed by Idaho Power’s
response.
Monitor the Primary Heating Rating (HSPF) of installed heating equipment and discuss
equipment selection and modeling practices with builders and raters. Idaho Power
understands equipment selection is a builder decision, but the company will encourage the
raters to continue to educate the builders on the benefits of equipment with higher HSPF as a
primary driver in energy savings for each home in the program.
Educate raters on potential savings from water heating. Idaho Power plans to create an
educational piece for distribution to raters and builders to educate them on the energy saving
advantage of installing heat pump water heaters in single family, new construction.
Monitor average ceiling height. Note: the QA provider believes this issue was due to a rater
modeling input error in a four-plex layout, not ceiling height. Idaho Power plans to work with
the program QA provider on ensuring the rater’s entered conditioned volume is reasonable
compared to the conditioned area.
2024 Plans
Idaho Power is pursuing a new QA provider for 2024. The company is also going to look for an
additional energy rater(s) to join the program in the Treasure Valley area.

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,
and county master gardeners.

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. Of the trees
planted in 2023, it is estimated each surviving tree will save approximately 11 kWh per year by
2033 and 33 kWh per year by 2043. The estimated savings for each tree is adjusted to reflect
the estimated survivorship of the tree.
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
In 2023, Idaho Power resumed holding in-person events only and did not offer any delivery
trees. Idaho Power distributed 2,462 trees to residential customers through the Shade Tree
Project. Because the best time to plant trees is in the spring and fall, Idaho Power held their
spring offering in April for customers in the Pocatello area and the fall event in October for
customers in the Treasure Valley. There were 1,273 trees distributed at two different events for
the spring offering and 1,189 trees distributed over three different events for the fall offering.
Idaho Power purchased the 3-gallon trees from a local wholesale nursery in advance of each
event. The species offered for each event depended on the trees available at the time of
purchase. Idaho Power worked with city and state arborists to select a variety of large-growing
deciduous trees that traditionally grow well in the climate and soils of the two participating
regions.
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 eligibility in the program remains two trees per address for the life of the
program.
In 2023, Idaho Power reached a huge milestone of not only giving away more than 15,000
trees, but also for celebrating a 10-year partnership with the Arbor Day Foundation for the
Shade Tree Project. To celebrate this milestone, the Arbor Day Foundation made a post on their
LinkedIn page congratulating Idaho Power on this achievement. Additionally, Idaho Power had

The fall campaign was similar, except it was directed toward Treasure Valley customers. Due to
slow enrollment, the company sent five batches of “enrollment open” emails in addition to
promotion on Facebook and X. Direct-mail letters were sent to customers who signed up,
outlining event details and directions on how to pick up their trees.
Figure 18. Enrollment Open email for Shade Tree Project
This year, the look and feel of the Shade Tree marketing campaign was updated to align with
the new over-arching energy efficiency campaign, “Good Energy,” which is reflected in the
“open enrollment” email shown above.
Cost-Effectiveness
For the Shade Tree Project, Idaho Power uses 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. In 2019, 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 realization rate based on survival. This calculator was used to determine the reported
program savings between 2019–2022.
In 2023, Idaho Power contracted with a third-party evaluator to perform an impact evaluation
and audit of the past trees distributed in the Shade Tree Project. The evaluation found that
while the existing calculator was acceptable for determining energy savings, the mortality rate
was higher than estimated, and the savings also needed to be adjusted for the heating impact
shade trees have on electrically heated homes.
Due to the size of the trees, Idaho Power does not claim savings until the fifth year after
planting. In 2022, Idaho Power began claiming savings for the trees planted in 2018 as well as
the additional growth savings from the growing trees planted between 2013 and 2017 that
were not previously claimed. In 2022, Idaho Power claimed 39,595 kWh of incremental
claimable savings for the trees planted between 2013 and 2018. However, the evaluated
savings were less than calculated because of higher mortality and the application of the electric
heat penalty. For simplicity and to reduce confusion, Idaho Power will report the first-year
savings for trees distributed five years prior without calculating the additional savings from the
growth of the older trees. For 2023, Idaho Power is reporting the first-year savings for the trees
distributed in 2019. Based on the evaluation, this value is 11,199 kWh.
While the incremental savings from the growth of older trees will no longer be reported,
the cost-effectiveness analysis is based on the modeled 40-year savings for the trees distributed
in 2023 and costs incurred during 2023. To determine the savings for the distributed trees,
Idaho Power used the savings and non-energy impact values from the i-Tree model and applied
the recommended mortality rates from the evaluation as well as the electric heat adjustment.
The cost-effectiveness calculations also include a 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. It is estimated that these trees will save approximately 24,238 kWh in 2063.
Based on the model, the project has a UCT of 0.31 and a TRC ratio of 0.42. If the amount
incurred for the 2023 evaluation was removed from the program’s cost-effectiveness, the UCT
would be 0.33 and the TRC would be 0.45.

Customer Satisfaction
After each offering, Idaho Power emailed a survey to participants. The survey asked questions
related to the program marketing, tree-planting education, and participants’ 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 and to identify opportunities for
improvement. 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 1,268 Shade Tree Project participants and 524 responses were
received, for a response rate of 41%. Some highlights included the following:
•Approximately 39% of respondents heard about the program from an Idaho Power
email, and over 28% learned of the program from a friend or relative.
•Over 84% of respondents were “very satisfied” with the information they received on
the planting and care of their shade tree, while almost 15% of respondents were
“somewhat satisfied.”
•Participants were asked how much they would agree or disagree they would
recommend the project to a friend. Nearly 96% of respondents said they “strongly
agree,” and almost 4% said they “somewhat agree.”
•Participants were asked how much they would agree or disagree they were satisfied
with the overall experience with the Shade Tree Project. Approximately 93% of
respondents indicated they “strongly agree,” and almost 7% “somewhat agree” they
were satisfied.
View the complete survey results in Supplement 2: Evaluation.
Evaluations
In 2023, Idaho Power contracted with a third-party evaluator to perform an impact evaluation
on the Shade Tree Project. Through the audit, the evaluator sampled 270 households and 492
trees. Of those sampled, 182 households and 319 trees were audited. During the audit, it was
found that 22% of the trees were confirmed deceased and 48% were not on the property—
either given away after the customer realized they didn’t have room/desire to keep the tree(s)
or removed due to landscaping changes.
Listed below are the evaluators’ recommendations (in italics) followed by Idaho Power’s

Consider charging a small fee for each tree. Idaho Power will explore this option to determine
if it is cost-effective and will help reduce program costs and increase energy savings.
Consider providing a watering bag with each tree. Idaho Power will research the effectiveness
of watering bags and determine whether it would be cost-effective to provide them with each
tree at future offerings.
Adjust planting guidance for electrically heated homes. Idaho Power will consider adjusting
planting guidance specific to electrically heated homes.
Partnering with residential builders for new construction projects. Idaho Power will investigate
current landscaping practices with local builders and determine whether this option could help
ensure the trees are planted in the correct location to maximize energy savings.
Adjust the mortality rate for the first 10 growing seasons. Idaho Power has updated the
mortality rate as recommended in calculating the future savings and cost-effectiveness for the
trees distributed in 2023.
Incorporate electric heating adjustments into calculations. Idaho Power has incorporated an
electric heat adjustment in calculating the future savings and cost-effectiveness for the trees
distributed in 2023. Because heating system or fuel type is not collected at the time of
enrollment, the survey results from the 2023 survey were applied in the calculation.
Adjust energy savings calculations. Idaho Power worked with the evaluators to determine how
best to model the future savings for the distributed trees. The evaluators reviewed Idaho
Power’s savings calculations for the trees distributed in 2023 to ensure the adjustments were
applied in accordance with the recommendations outlined in the evaluation.
Continue to use the spillover and non-energy benefits calculated. The updated savings model
the evaluators reviewed for Idaho Power also included the non-energy impacts of air pollution,
carbon, and storm runoff. These non-energy impacts were calculated using the same mortality
rate adjustment recommended by the evaluators. The spillover percentage is still applied in the
cost-effectiveness calculation.
2024 Plans
In light of the 2023 evaluation results, changes will undoubtedly need to be made to the Shade
Tree Project to be cost-effective going forward. Idaho Power commits to the purchase of the
spring and fall trees the year prior to each event, in order for the trees to be planted and grown
in a nursery to the desired size for the giveaway events. Because of this, Idaho Power plans to
continue the Shade Tree Project in 2024, with the spring offering to customers in the Magic
Valley and the fall event to customers in the Portneuf Valley. The program will continue to offer
in-person events only. The enrollment process will remain the same, using the Arbor Day

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 explore the opportunity to be
promoted in the 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 2024 offerings. Idaho Power will continue

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. Regional 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 primarily serve
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,
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 IDHW uses the DOE-approved energy audit program (Ecos) for the Idaho WAP and,
therefore, the Idaho CAP agencies use Ecos.
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
In 2023, Idaho Power made $2,361,439 available to Idaho CAP agencies. Of the funds provided,
$1,224,051 were paid to Idaho CAP agencies, while $1,137,388 were accrued for future funding.
This relatively large carry over was caused by supply chain limitations and labor shortages
limiting the number of homes CAP agencies weatherized.
In 2023, Idaho Power funds provided for the weatherization of 161 homes and one non-profit
building in Idaho. Of the funds paid in 2023, $1,110,445 directly funded audits, energy
efficiency measures, and health and safety measures for qualified customers’ homes
(production costs) in Idaho, and $111,045 funded administration costs to Idaho CAP agencies
for those homes weatherized. The non-profit building totaled $2,329 in production costs with
$233 as an administrative payment.

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 2023 agreement was $6,000. In 2023, Idaho CAP agencies had a combined
average cost per home weatherized of $6,897. Weatherization managers report that higher
costs of equipment caused higher averages in 2023.
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 2023 was
$690. Not included in this report’s tables are additional Idaho Power staff labor, marketing,
and support costs for the WAQC program totaling $75,626 for 2023. These expenses were in
addition to the WAQC program funding requirements in Idaho specified in IPUC Order

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 2023, $1,148,905 of unspent funds from 2022 were made available for expenditures in

Weatherization Measures Installed
Table 18 details home counts for which Idaho Power paid all or a portion of each measure’s
cost during 2023. 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, like 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.
This includes health and safety measures and home energy audits. Health and safety measures
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
ensure certain energy-saving measures work properly, they increase costs of the job.

Re-Weatherization
In May 2022, with support from EEAG, Idaho Power filed a proposal (IPC-E-22-15) with the IPUC
designed to address an increase in carryover funds by expanding eligibility for weatherization to
include homes that had been weatherized within the last rolling 14-year period but had not
received HVAC upgrades. Because these homes are not eligible to receive federal funding for
re-weatherization within a rolling 14-year period based on DOE guidelines, Idaho Power’s
proposal was to fund HVAC upgrades at 100% of the cost for these jobs. In November 2022, the
IPUC approved the company’s application in Order No. 35583, and the newly approved
re-weatherization option was implemented in April 2023.
After IPUC approval, a list of customers who received weatherization within a prior 14-year
rolling period but did not receive HVAC system replacements were provided to weatherization
managers. From these lists, weatherization managers began contacting customers and working
with HVAC contractors to determine whether HVAC upgrades were warranted and to identify
the type of system that would work best in the qualified home. Based on Idaho state WAP
guidelines, the HVAC contractor may replace the HVAC system of the previously weatherized
home and have the completed home inspected by the entity that issues the permit. Re-
weatherization jobs were invoiced to Idaho Power separately from regular WAQC jobs and
were paid with funds from each CAP agency’s individual portion of the annual WAQC amount,
which includes carry over of unused funds from previous years.
In 2023, 30 homes were re-weatherized: 5 in Capital region, 3 in Canyon/West, 17 in the
Southern region, and 5 in the Eastern region (Table 19).
Of the 30 homes weatherized, 14 were manufactured homes and 16 were single-family homes.
Heating upgrades included 10 zonal heat systems upgraded to ductless heat pumps, with five
more zonal heat systems upgraded to air-source heat pumps where the CAP agency built
ductwork to accommodate the system. Another 14 homes had their central electric furnace
upgraded to air-source heat pumps, and one home had an inoperable heat pump replaced.
Spending on re-weatherization jobs totaled $358,306, with $32,573 going toward
administrative costs. The average cost of the 30 re-weatherization jobs was $10,858. (Table 20)

Verification
Annually, Idaho Power verifies a portion of the homes weatherized under the WAQC program.
This is done through two methods. The first method uses a state monitoring process where
either an independent quality-control inspector or trained peers ensure measures were
installed to DOE and state WAP specifications. Utility representatives, weatherization personnel
from the CAP agencies, and IDHW homes weatherized by each of the CAP agencies. In 2023,
one Idaho Power funded home was chosen for review.
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. In 2023, 12 homes were verified by Idaho Power’s
home verifiers. Four of the 13 homes verified were re-weatherized homes and there were no
findings that would have required the CAP agency or contractors to return to the home for
corrections.
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. Idaho Power regional energy advisors and
EOEAs promote WAQC when working directly with customers in their communities, at fairs,
senior centers, and during other presentations in their regions. The CAP agencies also promote
the program through their outreach activities.
In 2023, Idaho Power mailed re-weatherization offer letters to select customers (lists provided
by CAP agency) in April and September. In November, Idaho Power mailed Baker County
customers an informational packet about programs customers can utilize to lower their energy
use and get bill assistance—within that packet was a letter about the Weatherization Assistance
program.

Cost-Effectiveness
In 2023, the WAQC program’s overall cost-effectiveness was 0.14 from the UCT perspective and
0.23 from the TRC perspective. These ratios include the savings and costs associated with the
re-weatherization efforts. The UCT and TRC for the WAQC-only portion of the overall program
are 0.16 and 0.25, respectively. The UCT and TRC for the re-weatherization efforts alone are
0.09 and 0.10, respectively.
The savings values were updated in 2020 based on a billing analysis of program participants
conducted by a third party; there were no changes to the values used for reporting from
2020 to 2023. While Idaho Power initially planned to update the analysis in 2023, the company
opted to delay the analysis for another year to minimize any lingering impacts from COVID-19,
as the billing analysis requires at least one year of pre- and post-weatherization data. Idaho
Power plans to update this billing analysis in 2024, which will include weatherization jobs from
2019 through 2022.
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. For Idaho state’s WAP, the agency weatherization
auditor uses the Ecos tool to conduct the initial audit of the home. The Ecos tool is used to
compare the efficiency of the home prior to weatherization to the efficiency after the proposed
improvements. The weatherization manager can split individual measure costs between Idaho
Power and the agency when a minimum of 15% is paid with agency funds.
The 2023 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 calculation removes the impacts of any accruals and reversals
associated with unspent dollars carried over into the following year. The total amount of
unspent funds carried into 2023 from the previous year was $11,517. Not including this amount
in the cost-effectiveness calculation would understate expenses in 2023. 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 and can ask the home verifiers more questions.
A customer survey was used to assess major indicators of customer satisfaction throughout the
service area. 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 114 of 147 households weatherized by the program
in 2023. Some highlights include the following:
•Almost 47% of respondents learned of the program from a friend or relative, and over
10% learned of the program from an agency flyer. Several people mentioned they
learned of the program from a bill stuffer or information with their Idaho Power bill.
•Almost 43% of the respondents reported their primary reason for participating in the
weatherization program was to reduce utility bills, while 20% wanted to improve the
comfort of their home. Almost 19% had concerns about their existing furnace.
•Over 20% reported they learned how air leaks affect energy usage, and over 19%
indicated they learned how to use energy wisely during the weatherization process.
•Over 15% of respondents said they learned how to program the new thermostat.
Most respondents (over 97%) reported they were likely to change habits to save energy,
and 80% reported they have shared all the information about energy use with members
of their household.
•Almost 89% of the respondents reported they think the weatherization they received
will significantly affect the comfort of their home, and most (91.74%) said they were
“very satisfied” with the program.
•Over 19% of the respondents reported the habit they were most likely to change to save
energy was turning the thermostat down in winter, while over 18% said they would turn
it up in the summer. Turning off lights when not in use was reported by 20% of the
respondents, and washing full loads of clothes was reported by over 17% 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.

2024 Plans
In 2024, Idaho Power will continue to provide financial assistance to CAP agencies while
exploring changes to improve program delivery, such as continuing the re-weatherization
program for the new year and working with IDHW on ways to streamline weatherization
services. The company will also continue to provide the most benefit possible to special-needs
customers by working with Idaho and Oregon WAP personnel and IDHW to develop
recommendations and ideas to help improve the program for customers with special needs.
Idaho Power plans to continue to verify approximately 5% of the homes weatherized under the
WAQC program via home-verification companies and state monitoring processes.
In 2024, 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.
In Idaho during 2024, Idaho Power expects to contribute the base amount plus available
carryover funds from 2023 of just over $1,137,300 to total $2,349,800 in weatherization
measures and agency administration fees. Of this amount, approximately $276,860 will be
provided in 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 as needed.
Idaho Power will continue to maintain the program content on its website and include it with
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 program also benefits certain customers on the Idaho State WAP waiting list.
When customer income overlaps both programs, this program may offer an earlier
weatherization date than the state WAP, 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 eligible. 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 indoor air quality, 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.

The Weatherization Solutions for Eligible Customers program uses a home audit tool called the
HAT14.1. The home is audited for energy efficiency measures, and the auditor proposes
upgrades based on the SIR ratio calculated by HAT14.1. 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 extended COVID-19 labor shortages, some contractors continued to experience
hardships hiring and training weatherization crew members, resulting in lower production
numbers in 2023 as compared to 2022. One Southern region contractor weatherized 12 Idaho
homes for the program. Of those 12 homes weatherized, 11 were single-family and 1 was a
manufactured home. The contractor reported increased costs for materials and equipment
over previous years.
An independent company performed random verifications of weatherized homes and visited
with customers about the program. In 2023, two homes were verified, and measures were
found to be correctly installed and performing as anticipated.
Marketing Activities
In 2023, the company placed digital advertisements in southern Idaho’s local newspaper,
the Times News, to promote the program (see Figure 19).

Cost-Effectiveness
In 2023, the Weatherization Solutions for Eligible Customers program cost-effectiveness was
0.13 from the UCT perspective and 0.19 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. In 2024, Idaho Power plans to

with the program.
For further details on the overall program cost-effectiveness assumptions, see Supplement 1:
Cost-Effectiveness.
Customer Satisfaction
A customer survey was used to assess major indicators of customer satisfaction with the
program throughout the service area. Program participants were asked to complete a survey
after their homes were weatherized. Survey questions gathered the following information:
•How customers learned of the program
•Reasons for participating
•How much customers learned about saving energy in their homes
•The likelihood of household members changing behaviors to use energy wisely
Idaho Power received survey results from 11 of 12 households weatherized by the program in
2023. Some highlights include the following:
•Over 27% of respondents learned of the program from a friend or relative, and over 27%
more learned of the program from a letter in the mail.
•Over 46% of the respondents reported their primary reason for participating in the
weatherization program was to improve the comfort of their home, and over 30%
wanted to reduce their utility bills.
•Twenty percent reported they learned how to reduce the amount of hot water used,
and 20% also said they learned how to use energy wisely.
•Over 18% of respondents said they learned how air leaks affect energy usage,
how insulation affects energy usage, and how to understand what uses the most energy
in their home.
•Almost 91% of the respondents reported they think the weatherization they received
will significantly affect the comfort of their home, and 100% said they were “very
satisfied” with the program.
•Over 33% of the respondents reported the habit they were most likely to change was
unplugging electrical equipment when not in use, and almost 10% said that washing full
loads of clothes, washing full loads of dishes, and turning the thermostat down in winter
were the habits they were likely to adopt to save energy.
A summary of the survey is included in Supplement 2: Evaluation.

The topic of energy efficiency remains a key focus during yearly meetings with customers.
Although many have leveraged incentives to boost efficiency in 2023, some faced challenges
due to limited staffing, which affected their participation.
Additionally, there's a growing trend toward monitoring and reducing carbon footprints,
extending beyond their own operations to include their suppliers' footprints. Some customers
are even considering a shift to 100% electric energy to align with their sustainability objectives
and reduce their carbon impact. Idaho Power has been actively assisting these customers in
evaluating energy efficiency opportunities to align effectively with their energy management
goals and sustainability objectives.
Overall, findings continue to indicate that the most cost-effective way for customers to achieve
their sustainability goals and reduce costs is through energy efficiency. Many are benefiting
from cohort programs, which facilitate long-term behavioral changes in their operations for
greater energy efficiency.

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.
Idaho Power has found providing facility energy assessments, customer technical training,
and education services are key to encouraging customers to consider energy efficiency
modifications. Incentives reduce customers’ payback periods for custom modifications and
promote energy-saving operations that might not otherwise be completed. The 2023 activities
and results not already described in the C&I Sector Overview are described below.
Custom Projects
The Custom Projects option provides incentives for 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 or energy management projects.
Additionally, Idaho Power operates SEM cohorts under the Custom Projects option.

Commercial & Industrial Sector—
Commercial and Industrial Energy Efficiency Program
Demand-Side Management 2023 Annual Report Page 111
The Custom Projects option also offers energy assessment services and customer training 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
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-saving measures are installed and operating and 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 energy savings are finalized
and the project costs are calculated.
On the larger and more complex projects, Idaho Power or a third-party consultant conducts
on-site power monitoring and data verification (M&V) before and after project implementation
to confirm energy savings are obtained and are within program guidelines. If changes in project
scope take place, Idaho Power recalculates 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 a new construction,
major renovation, addition, expansion, or change-of-space project. The customer may
otherwise lose savings opportunities for these types of projects. Initiated in 2004, the New
Construction option currently offers incentives for 34 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. A complete list of the measures offered through New Construction is
included in Supplement 1: Cost-Effectiveness. The new construction and major renovation
project design and construction process often encompasses multiple calendar years. In addition
to the customer incentive, a PAI is available to architects and/or engineers for supporting
technical aspects and documentation of a project.
Retrofits
Retrofits is Idaho Power’s prescriptive measure option for existing facilities that offers
incentives to customers in Idaho and Oregon for a defined list of energy efficiency upgrade
measures. Eligible measures cover a variety of energy-saving opportunities in lighting, HVAC,

building shell, food service equipment, and other commercial measures. A complete list of the
measures offered through Retrofits is included in Supplement 1: Cost-Effectiveness.
Program Activities—Custom Projects
The Custom Projects option provides incentives for both custom capital projects and
energy-management projects.
Incentive levels for custom capital projects remained the same in 2023, at $0.18 per estimated
kWh savings for one year, up to 70% of the project cost.
Idaho Power provides incentives for conducting pressurized, underground water leak
assessments and fixing those leaks. The program reimburses $1,000 per 5 miles of pipe
inspected with ultrasound leak detection for a third-party leak assessment in addition to the
standard capital project incentive of $0.18 per kWh of first-year savings for repair.
The energy management incentive of $0.025 per first-year kWh saved, up to 100% of the
eligible costs (added in 2020), also remained the same in 2023. Compared to typical custom
capital projects, energy management projects tend to have the following:
•A shorter measure life and a much lower cost
•O&M changes that save energy without interrupting the customer’s service
or production
•Cost-effective energy savings from measures rooted in low-cost O&M improvements
Compressed air system leak repairs are eligible under the energy management incentive at
$0.025 per kWh estimated to be saved in one year, up to 100% of project cost. Customers can
use their own instrumentation or work with one of Idaho Power’s third-party consultants to
identify leaks. Energy savings achieved from fixing leaks can be quantified, and project costs are
calculated by factoring in the material cost to fix the leaks as well as any labor requirements.
Idaho Power funds the cost of engineering services, and increased the maximum from $4,500
up to $6,000 for conducting energy scoping assessments to encourage its larger customers to
adopt energy efficiency improvements. The increase was implemented to allow additional
identification and estimation of demand response opportunities eligible for the Flex Peak
Program. This led to the initiation of 10 assessments that included Flex Peak Demand Response
strategy identification, eight of which were completed in 2023. The company is currently
contracted with six firms to provide scoping assessments and general energy efficiency
engineering support services through 2025. Two of the firms are focused on energy modeling to
support cohorts and other energy management offerings. The other four firms provide a wide
array of engineering services, including scoping assessments, detailed assessments,
energy modeling, Green Motors rewind facilitation, and various SEM programs.

Supply chain issues and customer staff turnover impacts continued to present challenges for
projects in 2023, and many projects were slowed down by these issues. Despite these
challenges, the Custom Projects option had a successful year with a total of 95 completed
projects (two of which were in Oregon) and achieved energy savings of 60,667 MWh (Table 22),
which is an 8% increase compared to 2022.
Idaho Power also received 104 new applications in 2023, representing a potential of
43,114 MWh of savings on future projects.
In 2023, Idaho Power contractors completed 45 assessments on behalf of Idaho Power
customers. These assessments identified over 54,078 MWh of savings potential, which was
used as the basis of savings for some projects completed in 2023 and will be used to promote
future projects.

Custom Projects engineers and the key account energy advisors visited large C&I customers to
conduct initial facility walk-throughs, commercial/industrial efficiency program informational
sessions, and training on specific technical energy-saving opportunities. Virtual/remote
capabilities were implemented when health or safety restrictions were necessary. Idaho Power
provided sponsorship for the 2023 ASHRAE Technical Conference that had numerous energy
efficiency related presentations. Idaho Power also provided a sponsorship and a leadership
team member to the American Council for an Energy Efficiency Economy to support North
American SEM Collaborative activities. Custom Projects engineers gave presentations on Idaho
Power programs and offerings at the Cohort for Schools Final Workshop, the Idaho Rural Water
Association Spring Conference, and multiple presentations at Cohort Workshops (virtual). Idaho
Power sponsored exhibit booths at the Idaho Rural Water Association Spring Conference,
ASHRAE Technical Conference, and Facilities Maintenance Expo.
The Streamlined Custom Efficiency (SCE) offering works to keep vendor engagement high,
targeting projects that are typically 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.
Idaho Power contracted with a third party to manage SCE data collection and analysis for each
project. In 2023, the SCE offering processed 27 projects totaling 7,607 MWh of savings and
$862,517 in incentives.
Cohorts
Idaho Power has SEM cohorts to engage with customers in group settings, allowing interaction
and economies of scale in working with multiple customers on SEM.
The Industrial Energy Efficiency Cohort (IEEC), Campus Cohort for Energy Efficiency (CCFEE), and
the Continuous Energy Improvement (CEI) Cohort for Schools program offerings are driving a
significant number of new projects in addition to an increase in projects from the SCE offering
while providing high levels of customer satisfaction with the programs. Reported cohort savings
correlate to energy management incentives; any capital projects promoted or identified in SEM
are reported and incentivized through the Custom Projects, New Construction or Retrofits
options of the C&I Program, not as a cohort savings number.
Cohorts are structured to offer three phases of support.
1.The active phase, 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 efficiency 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 to transition to self-sustaining operations.
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. Participants in this phase have the option
to participate in report-out workshops, but cohort-related energy savings are no
longer claimed and consultant support is minimal.
Water Supply Optimization Cohort (WSOC). The WSOC began in January 2016. The goal of the
cohort is to equip water professionals with the skills necessary to independently identify and
implement energy efficiency opportunities that produce long-term energy and cost savings.
The Eastern Idaho Water Cohort (EIWC) began in January 2018 with the goal to offer the WSOC
to the eastern part of Idaho Power’s service area. These two cohorts are collectively

represented under the WSOC offering, despite EIWC being two years junior to WSOC in terms
of program life. All the participants in this cohort completed their fifth year and transitioned
into the sustaining phase. The cohort offering was wrapped up, but engagements for capital
projects and trainings are still ongoing.
Wastewater Energy Efficiency Cohort (WWEEC). 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 increased the duration of WWEEC to further engage customers. The participants
in this cohort graduated to sustaining mode, or they ceased engagement with the program.
This cohort was transitioned to be supported through the new Industrial Energy Efficiency
Cohort for any wastewater facility that wants energy efficiency support.
Industrial Energy Efficiency Cohort (IEEC). Year one of the IEEC officially began in September
2022. Recruitment efforts for the first year were limited to municipal wastewater facilities or
large industrial facilities that had their own wastewater treatment systems. Two municipal and
four industrial customers signed up to participate in the first year.
Program year two began in September 2023. One facility did not continue with the program
due to exhausting their opportunities to save energy and nearing completion of their entirely
new wastewater system. Two new industrial customers joined for year two as the cohort has an
open enrollment to support new participants as they join. There are seven active participants in
year two. A new focus of the cohort that began in year two was to incorporate a “holistic
approach” that could support more than just wastewater systems. Since the cohort includes
large industrial customers, participants now can have subsystems upstream of the wastewater
treatment analyzed for energy efficiency opportunities. Examples of subsystems include
compressed air, refrigeration, HVAC, process equipment, and more. To this end, the cohort was
renamed from Industrial Wastewater Energy Cohort to Industrial Energy Efficiency Cohort.
This cohort continues to offer technical trainings to non-cohort participants to continue the
engagement of customers in the Idaho Power programs.
Campus Cohort for Energy Efficiency (CCFEE). The new CCFEE kicked off in June 2023 with five
different customers enrolled and 21 sites. This cohort is for any customer that operate a
campus of facilities including, but not limited to, universities, hospitals, correctional facilities,
and government facilities.
In 2023, three workshops were held for cohort participants in which they learned about HVAC
fundamentals, engaging employees in energy efficiency, building an energy team, and tracking
their energy usage with modeling. There were also on-site visits conducted for the participants.
The first visit was focused on touring the campus and doing a deep dive into their HVAC system

and controls to see how they might make it run more efficiently. The second visit was a focused
“treasure hunt” in which teams walked the site to identify energy efficiency opportunities.
So far, a total of 819 possible energy-savings measures have been identified across the 21 sites.
Project implementation on some of these measures has already taken place and will continue
to take place in 2024 with the final energy savings reporting period ending in July 2024.
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 sixth program year of the Cohort for Schools
ran from June 2022 through May 2023 to coincide with the standard school calendar; reported
energy savings are based on the program year.
Five school districts participated in the program in 2023. Of those five, three districts are
modeling all schools in their district. One district added two new facilities each in this program
year for a total of 40 facilities engaged with the offering during the 2023 program year. The
cohort is implemented by a third-party consultant that provided final savings reports for each
school district, which totaled 75,405 kWh. Incentive checks were provided totaling $1,885.13
for 2023. All facilities were re-baselined in 2023, as most were originally baselined in 2016, and
COVID-19 impacts have fundamentally changed the way many facilities are operating. This re-
baselining is the primary reason for lower savings this year compared to prior years.
Activities in 2023 included managing a list of energy efficiency opportunities for each facility
detailing low- 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 the list of opportunities 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.
Final program year workshops were held September 20, 2023, in Boise and September 21,
2023, in Twin Falls where results were reported for the program year. Districts shared
successes, lessons learned, and other details pertinent to their energy-saving journeys.
The 2023 to 2024 program year activities will continue until May 31, 2024. Idaho Power will
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
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 $2.00 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 2023, a total of 17 C&I customers’ motors were rewound, and the savings for the GMI was
63,538 kWh.
Program Activities—New Construction
In 2023, a total of 102 projects were completed, resulting in 10,642,465 kWh of energy savings
in Idaho and Oregon. The C&I construction industry was extremely active in Idaho Power’s
service area in 2023, although the industry is experiencing higher interest rates, causing delays
for some projects. New Construction had a 16% increase in number of projects and a 61%
decrease in total savings compared to 2022: in 2023 the average savings was 104,338 kWh
compared to 313,813 kWh in 2022.
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 strives to keep the New Construction option consistent by making changes
approximately every other year. The program was updated in 2023 by adding one new
measure to its offerings: an incentive for electrically heated indoor pool covers,
added September 5, 2023.
In addition to the customer incentive, a PAI is available to the architects 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
not have staff with a technical background in construction, which can make completing
applications and submitting documentation a challenge.
In 2023, a total of 51 projects, or 50% of the projects paid, received the PAI compared to
43 projects, or 49% of the total projects paid, in 2022. The PAI will continue to be offered due
to positive feedback from customers, architects, and engineers.

In 2023, third-party on-site verification occurred on 13 of the 102 projects, or 13% of the total
projects completed.
The New Construction engineer and Idaho Power energy advisors continued outreach to
customers, professionals, and professional organizations throughout 2023. Meetings were held
with specific customers or professionals to build relationships with the local design community
and to discuss Idaho Power’s New Construction option as well as the overall C&I Energy
Efficiency Program. An Idaho Power representative attended 14 Lunch and Learn sessions
provided by the IDL to provide energy efficiency program information to attendees.
Additionally, Idaho Power energy advisors and the New Construction engineer presented
program information to three professional organizations, three government agencies,
two suppliers, and three design firms. Idaho Power energy advisors also provided energy
efficiency program information during customer visits and calls.
See Supplement 2: Evaluation for the complete IDL report.
Program Activities—Retrofits
The Retrofits option achieved 14,457,180 kWh of energy savings in 2023,
representing 526 projects. Lighting retrofits comprised most of the energy savings and
project count.
In an effort to increase program participation, and in consideration of the feedback received
from several participating trade allies, the company reviewed the lighting measure incentive
levels. It was found that incentive increases could be cost-effectively made to respond to
market feedback. The incentive for screw-in LED lamps was removed to reflect EISA lighting
standards that became effective in 2023. At the same time, the company reviewed the
program’s non-lighting measures and determined some measures could be added to the menu
and some existing measures needed slight modification or removal.
Idaho Power offered two in-person technical lighting training classes for trade allies and large
customers on the topic of networked/luminaire level lighting controls. The company also held
Retrofits program update workshops in Twin Falls, Pocatello, and Boise, along with two virtual
options, to review the pending changes with trade allies and large commercial customers.
In addition, the company met with several trade ally companies (in person and virtually,
per their request) to review the Retrofits program and associated incentives.
Idaho Power continued its contracts with various consultants to provide ongoing program
support for lighting and non-lighting project 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 C&I Sector Overview for the company’s additional efforts to market the C&I Energy
Efficiency Program. Below are the option-specific marketing efforts for 2023.
Custom Projects
In addition to program-level marketing activities, Idaho Power created multiple brochures
including a revamped Industrial Energy Efficiency Cohort brochure, a Campus Cohort
recruitment brochure, a Compressed Air Leak Repair brochure, and a School Cohort Success
and Recruitment brochure. Idaho Power continued to present large-format checks to interested
Custom Projects participants and publicized these events to local media, when applicable.
Several of these were facilitated by key account energy advisors in 2023.
In 2023, Idaho Power continued to promote GMI as part of the C&I Energy Efficiency Program
marketing efforts.
New Construction
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 2023. Also, the brochure, website, and FAQs were
updated to reflect any program changes.
Retrofits
The company updated the brochures, website, and FAQs to reflect changes in the program
measures. Periodically, the company sent out emails promoting lighting incentives.
The company’s customer solutions advisors then followed up by making phone calls to
customers who received the email.
Cost-Effectiveness
Custom Projects
Projects submitted through the Custom Projects option must meet certain cost-effectiveness
requirements, which include TRC, UCT, and/or PCT tests, depending on the state. 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 and energy-savings
calculations, third-party engineering firms are sometimes used to provide an assessment, or
engineering M&V services are available under the Custom Projects option.
The UCT and TRC ratios for the program are 2.91 and 1.44, respectively. Non-energy impacts
were applied in 2023 based on an estimated per-kWh value by C&I 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 and the
International Energy Conservation Code (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 calculated mainly through a dollar-per-unit equation using
square footage, tonnage, operating hours, or kW reduction.
The UCT and TRC ratios for the program are 2.78 and 2.74, respectively. Non-energy impacts
were applied in 2023 based on an estimated per-kWh value by C&I 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 decrease in the program’s overall cost-effectiveness is largely due to the
decrease in savings between 2022 and 2023.
Complete, updated measure-level details for cost-effectiveness can be found in Supplement 1:
Cost-Effectiveness.
Retrofits
For most of 2023, Idaho Power used most of the same savings and assumptions as were used
after the program changes in 2022 for the Retrofits option. For all lighting measures,
Idaho Power uses a Lighting Tool developed by a third party. An initial analysis is conducted to
see if the lighting measures shown in the tool are 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 Technical Reference Manual (TRM) or the RTF are used to
calculate the cost-effectiveness. The program made slight modifications to its offerings in
September 2023. At that time, incentives for most lighting measures increased and the savings
for the food service equipment measures were updated with the current savings from the RTF
workbooks. The new savings were reflected on all applications after the September 2023
program update.
The UCT and TRC ratios for the program are 2.35 and 1.17, respectively. Non-energy impacts
were applied in 2023 based on an estimated per-kWh value by C&I 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 September 2023 update can be
found in the Demand-Side Management 2022 Annual Report, Supplement 1: Cost-Effectiveness.
Customer Satisfaction
In 2023, a survey was sent to Retrofits customers who had a lighting project installed by a
contractor to evaluate the customers’ satisfaction level. Survey questions gathered information
about how customers learned of the program and their satisfaction with the program,
contractor, and equipment.
The survey invitation was sent to 251 program participants, and Idaho Power received survey
results from 69 respondents. Some highlights include the following:
•More than 56% of respondents learned of the program from a contractor, and more
than 14% learned of the program from an Idaho Power employee.
•Approximately 84% of respondents said they were “very satisfied” with the program,
and almost 12% of respondents indicated they were “somewhat satisfied.”
•Approximately 86% of respondents said they were “very satisfied” with the
contractor they hired to install their equipment, and approximately 12% of
respondents indicated they were “somewhat satisfied.”
•Nearly 90% of respondents said they were “very satisfied” with the equipment
installed, and over 7% of respondents said they were “somewhat satisfied.”
A copy of the survey results is included in Supplement 2: Evaluation.

launched in 2020, will be marketed and potentially expanded in 2024 to allow for calculations
from other types of ultrasonic leak detectors.
Activities and coaching will continue for the campus, school, and industrial cohort participants.
The Industrial Wastewater Energy Cohort transitioned to a holistic approach offering and
became the IEEC to support other energy efficiency opportunities in addition to wastewater.
This will allow recruitment to broaden in 2024 to more industrial customers without
wastewater treatment systems.
Idaho Power will continue to provide the following:
•In-person or virtual site visits and energy-scoping assessments by Custom Projects
engineers or consultants to identify projects and energy savings opportunities.
•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
Idaho Power will continue to build relationships in 2024 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 continue to offer a menu of lighting and non-lighting incentives to commercial
customers in 2024.

Description
The Commercial Energy-Saving Kit (Commercial ESK) program was offered to commercial
business customers in Idaho and Oregon. One kit was offered to business customers who had
not previously received a commercial kit. The kit included: two 9-watt LED A lamps, two 8-watt
LED BR30 lamps, a bathroom aerator, an exit sign retrofit, and a kitchen aerator. Idaho Power
used a third-party vendor for kit assembly and mailing. The vendor sent the kit directly to the
customer on the company’s behalf. The Commercial ESK program closed in June 2023.
Program Activities
The savings for Commercial ESK were largely based on the assumed installation rates for each
kit item. A 2022 evaluation recommended the company consider removing exit sign retrofit kits
and the aerators due to low installation rates and the associated lower savings. Additionally,
the evaluators recommended the company remove the LED lightbulbs from the kit due to the
EISA lighting standards that went into effect in 2023. The 2022 evaluation recommended that
Idaho Power consider providing other measures to add to the kit.
Idaho Power consulted with its commercial kit vendor to identify any additional measures.
One suggestion from the evaluator was occupancy sensors, but there were concerns around
proper installation and compatibility with existing systems as well as cost-effectiveness.

Marketing Activities
In 2023, Idaho Power promoted the commercial kits using LinkedIn ads, March through June,
resulting in 548 clicks.
The company displayed a pop-up ad to small business customers who logged into My Account
in May, resulting in 211 users clicking on the ad. Customers signing into My Account could click
the pop-up ad and request a kit through the vendor’s online order form.
In March, April, May, and June, the company sent an email to over 14,000 business customers.
This tactic resulted in a 45.19% open rate and 213 kits ordered the day the March email was
sent, a 42.9% open rate and 121 kits ordered the day the April email was sent, a 42.7% open
rate and 131 kits ordered the day the May email was sent, and a 41.48% open rate and 103 kits
ordered the day the June email was sent. Idaho Power’s customer solutions advisors (CSA) also
promoted the commercial kit during their calls with business customers and offered to sign up
customers who requested the kit during the call.
Cost-Effectiveness
Because no deemed savings values exist for the Commercial ESK program, Idaho Power made
several assumptions. When the offering launched in mid-2018, the installation rates of the
items in the kit were unknown. Idaho Power estimated the installation rates based on
professional judgement. Idaho Power updated this assumption in 2021 based on the follow-up
survey sent to customers in 2020. In 2022, evaluators surveyed 2021 participants and updated
the installation rates for each item.
At the November 2021 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. For the LEDs and aerators, savings vary based on the average
annual hours of use (HOU) and annual gallons of water used by business type. As recommended
by the evaluators, Idaho Power continued to update the electric water heat saturation
assumptions based on the self-reported fuel type at the time of enrollment. However, Idaho
Power was unable to update the installation rates as recommended by the evaluation. Idaho
Power received 63 responses to its survey. While the installation rates appeared higher than
RECEIVED

IDAHO PUBLIC
UTILITIES COMMISSION
Commercial & Industrial Sector—
Commercial Energy-Saving Kits
Demand-Side Management 2023 Annual Report Page 125
what was shown in the evaluation, the results were not statistically significant. Therefore, Idaho
Power used the installation rates from the 2022 evaluation.
The 2023 average savings per kit was 170 kWh, which is an increase over the 2022 average kit
savings of 148 kWh. This increase in per-unit savings is largely due to the variety of
self-reported business types that received kits, which impacted the HOU and gallons of water
use assumptions. While the kits were cost-effective in 2023, the offering continued to face
cost-effectiveness challenges. With the full implementation of the EISA lightbulb standards in
July 2023, the evaluators recommended removal of LED lightbulbs from the kit offering. Due to
the declining savings opportunities and rising costs, the kits would no longer be cost-effective
going forward. The program closed June 30, 2023.
For more information about the cost-effectiveness savings and assumptions, see Supplement 1:
Cost-Effectiveness.
Customer Satisfaction
In 2023, a follow-up survey was sent to program participants. The purpose of the survey was to
obtain the installation rates for the kit items. Idaho Power received 63 responses. Due to the
low number of survey responses, Idaho Power did not use the installation rates from the survey
to update the savings assumptions for the program.
• 73% of respondents said they were “very satisfied” with the program, and almost 16%
of respondents indicated they were “somewhat satisfied.”
• 71% of respondents indicated they installed both 9-watt LED A lamp lightbulbs.
• 52% of respondents indicated they installed the first 8-watt LED BR30 lightbulb while
40% of respondents indicated they installed the second 8-watt LED BR30 lightbulb.
• 16% of respondents indicated they installed the LED retrofit kit for exit signs.
• 43% of respondents indicated they installed the kitchen aerator.
• 44% of respondents indicated they installed the bathroom aerator.

Description
The Flex Peak Program is a voluntary demand response program where large C&I customers in
Idaho and Oregon are eligible to earn a financial incentive for reducing load. The objective of
the program is to reduce the demand on Idaho Power’s system during periods of high energy
demand or for other system needs.
The program originated in 2009—as the FlexPeak Management program—administered 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, and 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. A new program option per Case IPC-E-22-24 went into effect in 2023, with the addition
of the automatic dispatch option.
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.

The parameters of the program are in Schedule 76 in Oregon and Schedule 82 in Idaho,
and include the following:
• A minimum of three events will occur each program season
• Events can occur any weekday (excluding Independence Day and Labor Day) between
3 and 10 p.m. and last between two to four hours
• Events can occur up to four hours per day and up to 16 hours per week, but no more
than 60 hours per program season
• Idaho Power will notify participants four hours prior to the initiation of an event
• If prior notice of an event has been sent, Idaho Power can choose to cancel the event
and notify participants of cancellation at least 30 minutes prior to the start of the event
• Customers can choose a manual or automatic dispatch option (2023 was the first year
Idaho Power offered an automatic dispatch option)
A minimum of three events allows the company to test processes and software and helps
customers fine tune their curtailment plan. Additionally, the company believes by calling at
least three events per season the program will be more effective in providing consistent and
reliable reduction.
Program Incentives
The program includes both a fixed and variable incentive payment. The fixed incentive is
calculated by multiplying the actual kW reduction by $3.25 for weeks when an event is called or
the weekly nominated kW amount by $3.25 for weeks when an event is not called. The variable
energy incentive is calculated by multiplying the kW reduction by the event duration hours to
achieve the total kilowatt-hour (kWh) reduction during an event. The variable incentive
payment is $0.20 per kWh and is implemented for events that occur after the first four events.
The program also includes an incentive adjustment of $2.00 per kW not achieved for each
event hour when participants do not achieve their nominated amount during events, which is
subtracted from their credit or payment. Incentives are calculated using Idaho Power’s interval
metering billing data. Participants can elect to have their incentive checks mailed or their
Idaho Power account credited within 45 days of the end of the program season. The incentive
structure offered for the 2023 season is listed in Table 24.

Program Activities
In 2023, 82 participants enrolled 271 sites in the program. This was an increase of
18 participants and 120 sites from the previous year (2022). Existing customers were
automatically re-enrolled. There were five customers (eight sites) that did not re-enroll,
as demand reduction was not in line with their facilities’ needs for 2023. Participants had a
nominated demand reduction of 31.4 MW in the first week of the program and ended the
season with a nominated demand reduction of 37.0 MW. The maximum potential demand
reduction of the program came from the nominated amount in the ninth week of the season at
38.8 MW. The reason the company uses the full nominated amount from the highest week for
the maximum potential demand reduction is because events can and have achieved the full
nominated amount.
The weekly nomination was comprised of 255 of the 271 sites. The maximum realization rate
achieved during the season was 86%, and the season average for the three events combined
was 69%. The realization rate is the percentage of demand reduction achieved versus the
amount of demand reduction committed for an event. The highest hourly demand reduction
achieved was 32.9 MW (at generation level) during the August 1 event (Table 25).

Enrollment specific to the Oregon service area included six participants totaling nine sites
enrolled. These nine sites had an average nominated capacity for the season of 8.4 MW and
achieved a maximum reduction during the season of 10.0 MW during hour four on the August 1
event. Individual participant performance as well as total program event performance can be
found in Supplement 2: Evaluation.
New in 2023 was the automatic dispatch option. Customers that chose to participate in this way
utilized a load control device that Idaho Power operates. There were two automatic dispatch
participants controlling a total of nine sites in 2023. A total of 80 participants chose the manual
option for 262 sites.
New this year, Idaho Power initiated 10 energy assessments for large customers to help
determine potential for load shed and identify specific load shed tactics and sequences that
could be initiated for events. Eight assessments were completed and resulted in three
enrollments into the program for 2023.

Marketing Activities
In 2023, the program brochures and website were updated to reflect the addition of the
automatic dispatch option. The company ran a My Account pop-up ad in May promoting
enrollment to large commercial customers that resulted in 65 users clicking on the ad.
In March, the company emailed 21 national accounts in its service area. Also, the company sent
an email in March to 11,381 business customers and an email in May to 490 business
customers. This tactic resulted in a 44.27% open rate in March and 43.05% open rate in May.
Additionally, a LinkedIn ad ran March through May promoting program enrollment resulting in
1,519 clicks, and a thank-you note to participants was posted on LinkedIn in October.
This year the company included new marketing tactics of digital display ads and search engine
marketing. Web users were exposed to 2,047,636 display ads (animated GIF image ads

Cost-Effectiveness
Idaho Power determines cost-effectiveness for its demand response programs using the
approved method for valuing demand response under IPUC Order No. 35336 and approved by
the OPUC on February 8, 2022, in Docket No. ADV 1355. Using financial and avoided cost
assumptions from the 2021 Integrated Resource Plan, the defined cost-effective threshold for
operating Idaho Power’s three demand response programs for the maximum allowable
60 hours is $84.57 per kW under the current program parameters.
The Flex Peak Program was dispatched for 12 event hours and achieved a maximum load
reduction of 32.9 MW and a maximum nomination capacity of 38.8 MW. The total cost of the
program in 2023 was $1,076,149. Had the Flex Peak Program been used for the full 60 hours,
the potential cost would have been approximately $1.4 million. Using the potential cost and the
average maximum capacity results in a cost of $36.40 per kW, which shows the program was
cost-effective.
A complete description of Idaho Power cost-effectiveness of its demand response programs is
included in Supplement 1: Cost-Effectiveness.
Evaluations
To evaluate the program each year, Idaho Power prepares a Flex Peak Program End-of-Season
Report that presents load reduction calculations and analysis, and detailed results from the
program season. See Supplement 2: Evaluation for the 2023 report. A brief overview of the
results is provided in this section.
Figure 23 compares the average and maximum demand reduction achieved for each event.
The maximum actual demand reduction achieved ranged from a low of 21.2 MW with a

2024 Plans
For the upcoming season, Idaho Power will continue its focus on retaining currently enrolled
participants and will be using email marketing, paid search, digital display ads, and other tactics
to boost program enrollment. Energy assessments conducted by Idaho Power engineers or
contract engineers will be offered to large customers to help determine potential for load shed
and identify specific load shed tactics and sequences that could be initiated for events.
The company will continue to assess customer interest and seek collaborative ways for their
participation in the program. The program will also continue to be marketed along with the C&I

Description
Oregon Commercial Audits identifies opportunities for all Oregon C&I 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.

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.
2024 Plans
Idaho Power does not expect to make any operational changes in 2024. 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 paid
100% of the cost to assess eligibility and install lighting measures for these customers, using a
third-party contractor to operate the program. SBDI was offered to eligible customers in a
strategic geo-targeted approach. The offering closed in March 2023 after offering the
program to customers throughout the Idaho Power service area and due to cost-effectiveness
challenges.
Program Activities
SBDI was planned to be a three-year program—concluding after the offer was extended
to customers in each of the company’s regions. The program ended in March 2023. In January
2023, the company’s contractor followed up on the marketing letters sent at the end of 2022
with calls to eligible customers offering one final 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. In 2023 the SBDI contractor completed
166 project installations, and 14 post-installation inspections prior to program close in March.

Marketing Activities
No proactive marketing was performed in 2023 as the program was scheduled to end in
March 2023. The final proactive marketing of SBDI was performed late in 2022, which resulted
in the final activity early in 2023. The program contractor followed up with 130 phone calls in
January 2023, after customers received the letters.
Cost-Effectiveness
In 2023, 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 0.97 and 1.48 respectively.
Non-energy impacts were applied in 2023 based on an estimated per kWh value by C&I
end-uses. These values were provided by a third-party as part of the 2019 impact evaluation of
the New Construction and Retrofits options. Finally, if the amount incurred for the 2023
evaluation was removed from the program’s cost-effectiveness, the UCT would be 1.08 and the
TRC would be 1.64.
In 2022, Idaho Power discussed the future cost-effectiveness challenges facing the program
with EEAG. These challenges included the reduced savings potential from screw-in lightbulbs
and increased costs associated with materials and labor. If the cost of this free service were to
rise, it would be increasingly difficult for the program to be cost-effective from the UCT
perspective. As a result, the offering closed in March 2023.
Details for the program cost-effectiveness are in Supplement 1: Cost-Effectiveness.
Customer Satisfaction
Idaho Power’s third-party implementer sent customer satisfaction surveys to
program participants in 2023, of which 48 surveys were completed. Key highlights include
the following:

Irrigation Sector Overview
Page 138 Demand-Side Management 2023 Annual Report
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 domestic water supply or the
irrigation of lawns, parks, cemeteries, and golf courses.
• In July 2023, the active irrigation service locations totaled 21,630 system-wide, which is
an increase of 1.4% compared to July 2022. 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 1,805,855 MWh of energy usage in 2023,
versus 1,949,766 MWh in 2022. The approximately 8% decrease is primarily because of
the substantially cooler, wetter year. This sector represented nearly 12% of Idaho
Power’s total electricity sales, and approximately 30% of July sales. Though annual
electricity use may vary substantially for weather-related reasons, and there are now
more irrigation customers, the energy-use 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, dropping from 6,954,805 kWh in 2022 to 4,562,888 kWh in 2023. This was due
primarily to a decrease in the average size of the custom projects and a decrease in the savings
and measures from small maintenance upgrades in the Menu Incentive Option of the program.
Idaho Power re-enrolled the majority of the 2022 Irrigation Peak Rewards participants in 2023,
with 2,439 service points and a maximum load reduction potential of 252.1 MW. Table 26
summarizes the overall expenses and program performance for both programs and shows the
actual load reduction was 187.7MW.

Irrigation DSM 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.
Irrigation Peak Rewards. A demand response program designed to reduce load from irrigation
pumps during periods of high energy demand or for other system needs. Participating service
points are automatically controlled by Idaho Power switches or manually interrupted by the
customer for very large pumping installations, for certain system configurations or when switch
communication is not available.
Green Motors Initiative. An energy efficiency program to incentivize the rewinding of irrigation
motors. 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.
Marketing
In 2023, the company mailed a winter edition of Irrigation News to all irrigation customers in its
service area. In part, the newsletter educated customers about energy efficiency incentives,
how to download the mobile app, and education on and enrollment information for the
Irrigation Peak Rewards program.

The application for new or upgraded service was put into a tear-pad version so agricultural
representatives (ag reps) could easily provide an application to an irrigator during
one-on-one visits.
The company also placed numerous print ads in 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 1,430 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.
Additionally, a Facebook and Instagram post ran in March for national agriculture day. The post
featured an ag rep promoting irrigation programs.
Customer Satisfaction
Idaho Power conducts the Burke Customer Relationship Survey each year. In 2023, on a scale of
zero to 10, irrigation survey respondents rated Idaho Power 7.52 regarding offering programs
to help customers save energy, and 7.34 related to providing customers with information on
how to save energy and money. Almost 23% 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,
95% are “very” or “somewhat” satisfied with the program.
Training and Education
Idaho Power continued to market its irrigation programs by offering in-person workshops,
staffing booths at three agricultural shows/expos, dealer presentations, and offering individual
presentations to irrigation customers. In 2023, Idaho Power provided seven irrigation
workshops and one conference seminar for the Irrigation Efficiency Rewards and Irrigation Peak
Rewards programs; this number was greatly increased compared to 2022 as COVID-19
restrictions were reduced. Approximately 369 customers attended in-person workshops or
the seminar.
Field Staff Activities
Idaho Power ag reps were available to be on-site with customers in 2023, offering Idaho Power
energy efficiency and demand response program information, education, training,

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 Option and Menu Incentive Option. 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 $0.25 per estimated kWh saved in one year, not to exceed 10% of the
project cost.

2023 February 15, 5:04PM
IDAHO PUBLIC
UTILITIES COMMISSION
Irrigation Sector—
Irrigation Efficiency Rewards
Demand-Side Management 2023 Annual Report Page 143
For existing system upgrades, the incentive is $0.25 per estimated kWh saved in one year or
$450 per estimated kW demand reduction, whichever is greater. The incentive is limited to 75%
of the total project cost.
The qualifying energy efficiency measures include 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 and analyzes each project, considering prior usage history,
irrigation system maps, system design details, invoices, and, in many 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 seven measures:
1. New flow-control type nozzles
2. New nozzles for impact, rotating, or fixed head sprinklers
3. New or rebuilt impact or rotating type sprinklers
4. New or rebuilt wheel-line levelers
5. New complete low-pressure pivot package (sprinkler, regulator, and nozzle)
6. New drains for pivots or wheel lines
7. New riser caps and gaskets for hand lines, wheel lines, and portable main lines
Incentives are based on a predetermined kWh savings per component from the RTF.
Green Motors Initiative
Idaho Power also participates in the GMPG GMI. Under the initiative, Idaho Power pays service
centers $2.00 per hp for motors 15 to 5,000 hp that receive a verified Green Rewind. Half of
that incentive is passed on to irrigation customers as a credit on their rewind invoice.
Program Activities
In 2023, a total of 643 projects were completed: 566 Menu Incentive Option projects that
provided an estimated 2,054 MWh of energy savings, and 77 Custom Incentive Option projects
that provided 2,504 MWh of energy savings (50 new systems and 27 existing systems).
Also, a total of four irrigation customers’ motors were rewound under the GMI and accounted
for 4,463 kWh in savings.
Marketing Activities
In addition to activities mentioned in the Irrigation Sector Overview, the Idaho Power ag reps
and program specialist worked one-on-one with irrigation dealers and vendors who are key to

the successful promotion of the program. Between February and March 2023, the ag reps held
seven workshops for their customers. The workshops focused on the Irrigation Efficiency
Rewards program, the Irrigation Peak Rewards program, water supply outlook forecasts,
Idaho Power’s hydro operations, and how Idaho Power meets customer’s energy needs in
extreme conditions. The ag reps shared Idaho Power’s website and self-help tools. The ag reps
also visited irrigation vendors in their area to distribute custom and menu efficiency
applications and talk about the program.
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 installation through aerial photographs, maps, and field
visits 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 2023, Idaho Power used the same savings and
assumptions source used in 2022.
The UCT and TRC for the program without Green Motors are 2.05 and 2.22, respectively.
With Green Motors, the UCT and TRC are 2.06 and 2.22. If evaluation expenses were removed
from the program’s cost-effectiveness, the UCT and TRC would be 2.11 and 2.23, respectively.

Evaluations
In 2023, Idaho Power contracted with a third party to conduct an impact evaluation on the
Irrigation Efficiency Rewards program. The review noted the program is well-managed with
comprehensive support from a knowledgeable and responsive Idaho Power staff. The
evaluators reviewed sample project data, completed desk reviews, conducted site verifications,
and verified kWh savings claimed. The report noted that the Menu Incentive Option of the
program is streamlined and easily understood, and that the Custom Incentive Option savings
are highly customized and calculated by the ag reps and program engineer. The evaluators
calculated a 2022 program year kWh savings realization rate of 97.4% (99.9% for the Menu
Incentive Option and 95.8% for the Custom Incentive Option). Recommendations from this
evaluation are listed below (in italics), followed by Idaho Power’s response:
Streamline Custom Incentive Option calculations. Idaho Power will take this recommendation
under advisement and plans to review the Custom Incentive Option's calculations to simplify
the process in 2024.
Create a reference for Custom Incentive Option calculation assumptions. The company agrees
with this recommendation and will incorporate a reference table for assumptions in 2024.
Review baseline energy consumption for irrigation system projects with multiple pumps.
The company agrees with this recommendation and will take this recommendation under
advisement when reviewing multiple pump projects in 2024.
Continue to use meter data to calibrate the Custom baseline energy consumption.
Idaho Power agrees with this recommendation and will continue to use and document the AMI
data for projects in 2024.
Continue to organize digital files. The company will take this recommendation under
advisement for continuous improvement.
See the complete analysis report in Supplement 2: Evaluation.
2024 Plans
Irrigation Efficiency Rewards program marketing plans typically include conducting at least
seven customer-based irrigation workshops to promote energy efficiency, technical education,
and program understanding. Idaho Power has committed to a booth at the Idaho Irrigation
Equipment Show & Conference, Western Ag Expo, Idaho Potato Conference, and the Southern
Ag Show in 2024 to promote the Irrigation Efficiency Rewards program and what customers can
do to save energy and participate in the programs to earn an incentive. Marketing the program
to irrigation supply companies will continue to be a priority, as they are an important part of
getting the program in front of customers.

Description 
Idaho Power’s Irrigation Peak Rewards program is a voluntary, demand response program 
available to all agricultural irrigation customers. The Irrigation Peak Rewards program pays 
irrigation customers a financial incentive to interrupt the operation of participating irrigation 
pumps at potentially high system load periods (summer peak). Initiated in 2004, the purpose of 
the program is to minimize or delay the need for new supply‐side resources.  
Idaho Power estimates future capacity needs in the Integrated Resource Plan and then plans 
resources to mitigate shortfalls. The Irrigation Peak Rewards program is a result of this planning 
process, and the success of the program is measured by the amount of demand reduction 
available to Idaho Power during periods of high energy demand or for other system needs. 
The Irrigation Peak Rewards program is available to Idaho Power irrigation customers receiving 
service under schedules 24 and 84 in Idaho and Oregon. All irrigation customers are eligible to 
participate. There are two options for shut off: an automatic dispatch option and a manual 
dispatch option. Due the size of the program, the participants are currently split into four 
approximately equal‐sized groups that can be used independently on different days or used all 
together at the same time or staggered out at different times on an event day.

Automatic Dispatch Option. Pumps enrolled in the Automatic Dispatch Option have one of two
devices installed that control the irrigation pump(s) via signal from Idaho Power. This option
requires that all pumps shut off at a site for the demand-response event. Approximately 99% of
the devices are demand response units (DRU) and use Idaho Power’s Automated Metering
Infrastructure (AMI) to send a signal that opens the contactor and shuts off the pump.
The other 1% of automatic dispatch participants have a cellular device (cell device) installed.
The cell device has the same load-control feature as the AMI DRU, except a cellular network
signal is used to send the command for shut off during the event.
Manual Dispatch Option. Pumps with at least 1,000 cumulative hp, or that Idaho Power has
determined to have limited communication availability, or due to system configuration, are
eligible for the Manual Dispatch Option, where participants manually control which pumps are
turned off during a load control event. Manual participants are required to select a nominated
load reduction of kW available and anticipated for shut off during the season. They may choose
to shut down all or partial load at the site. Aggregate customers participate manually by
identifying a group of pumps across multiple sites to participate as an aggregate. The customer
nominates a kW reduction for the aggregate and is compensated by the actual load reduction
during the event.
Program event parameters for both interruption options are listed below:
• Season dates June 15 to September 15
• Minimum of three events per season
• Events may occur any weekday or Saturday (excluding Independence Day and Labor Day
holidays) between the hours of 3–10 p.m. (standard interruption option), or between
the hours of 3–11 p.m. (extended interruption option)
• Events may occur up to four hours per day and up to 16 hours per week, but no more
than 60 hours per program season—applies to both standard interruption option and
extended interruption option
• Idaho Power notifies automatic participants by phone, email, and/or text messaging
four hours before the start of the event whenever possible
• Idaho Power notifies manual participants by phone, email, and/or text four hours before
the start of the event
• Idaho Power may cancel the event and notify participants of the cancellation up to
30 minutes before the event start time
• Parameters for Irrigation Peak Rewards do not apply to system emergencies
The Irrigation Peak Rewards incentive structure includes fixed incentives (billing credits) and
variable event-related incentives. Participants receive fixed incentives that are not tied to
events: a demand credit and an energy credit. The fixed demand and fixed energy credits for

the automatic dispatch participants are applied to the monthly bill for billing dates June 15
through September 15. The fixed demand and fixed energy credits for the manual dispatch
participants are paid with a check. Credits are prorated for periods when meter reading/billing
cycles do not align with the Irrigation Peak Rewards season dates. Monthly billing credits for
2023 are summarized in Table 27.
•Fixed demand credits are calculated by multiplying the monthly billing kW by the
demand-related incentive amount
•Fixed energy credits are calculated by multiplying the total monthly billing kWh usage by
the energy-related incentive amount

Variable incentives apply if more than four events occur in the season. Participants who choose
the extended interruption option (3–11 p.m.) are paid a higher variable credit. The variable
incentive rates for 2023 are listed in Table 28.

Program rules allow customers to opt out of dispatch events while incurring an opt-out fee of
$6.25 per kW. The opt-out fee is calculated by multiplying $6.25 times the kW based on the
current month’s billing or kW not achieved for Manual Dispatch Option participants. The kW
not achieved for the Manual Dispatch Option refers to the amount that was nominated minus
the actual kW reduction that was achieved. The opt-out penalties will not exceed the total
credit that would have been paid with full participation.
Idaho Power has expanded the use of AMI technology with the use of DRUs installed at pump
locations. AMI technology provides the ability to turn off pumps during an Irrigation Peak
Rewards event by sending a command through the power line. The AMI system also allows
Idaho Power to analyze the interval metering data of participating pumps during load control
events. Interval metering reports provide data to help determine which DRUs functioned
properly, and which pumps were turned off and stayed off during the event. During the 2023
season, 2,612 DRUs were active and installed at 2,309 pump locations.
In addition to using AMI technology, Idaho Power developed its own load control device.
This device uses a cellular network signal to communicate with and shut off the pump during a

load-control event. Hourly usage data is not available for these sites. During the end of 2020
and spring 2021 many of the cellular devices were exchanged for DRUs due to an AMI
substation expansion project. Only 34 pump locations remain with 42 cellular devices.
Program Activities
In January 2023, Idaho Power mailed Irrigation Peak Rewards enrollment packets to all
irrigation customers. The packets included an enrollment worksheet with estimated credits for
participation, contact worksheets, and a program brochure. Total billing demand was
361.6 MW with 2,439 pumps enrolled for the 2023 season (2,309 with DRUs, 33 with cell
devices, and 97 participating under manual option).
For purposes of the program, the three regions shown on Figure 2 (Introduction section) are

Demand-Side Management 2023 Annual Report Page 151
In 2023, Idaho Power enrolled 2,439 (11.2%) of the eligible service points in its service area in
the program. This was an increase of 13.9% participating service locations over 2022.
Program participants in 2023 had a combined billing demand of 361,590 kW, an increase from
the 2022 season, where participant billing demand totaled 346,333 kW. The key factor
impacting the higher participation was efforts by the ag reps to increase participation in the
spring by contacting the 150 customers with the highest demand.
Though enrollment was higher, the maximum potential capacity was lower in 2023 due to both
the change in the line loss calculation and the coincident factor for pumps, which can vary from
year to year due to weather and crop type.
Idaho Power actively monitors and maintains the reliability of participating devices both
pre-season and during the season. Communication status reports are reviewed weekly to
identify possible issues at a participating pump. The company worked with three electrical
contractors across the region in 2023 to maintain, troubleshoot, repair, and exchange
program devices.
In 2023, participants were organized into four groups, labeled A, B, C, and D. Table 30 shows
the event performance by date. The program was used on seven days. Three days had two
groups participating, two days had all four groups participating, and two days had one group
participating. Each participant experienced 16 total event hours in the season. The program
maximum potential demand reduction was 252.1 MW and the actual maximum demand
reduction achieved was 187.7 MW on August 1, 2023, with all four groups participating
(Table 30). Demand reduction analytical methods and results are provided in the end-of-season
report in Supplement 2: Evaluation.

Marketing Activities
In 2023, the program brochures and website were refreshed. Idaho Power used workshops,
direct-mail, and outreach calls to encourage past participants to re-enroll in the program and
potential new participants to enroll for the first time. The brochure, enrollment worksheet,
and contact worksheet were mailed to all eligible participants in January 2023.

The company ran a My Account pop-up ad in May promoting enrollment to irrigation
customers. It resulted in 22 users clicking on the ad. In April, the company sent an email to
2,816 irrigation customers and an email in May to 123 irrigation customers. This tactic resulted
in a 47.20% open rate in April and 52.86% open rate in May. Additionally, a Facebook and
Instagram ad ran March through June promoting program enrollment resulting in 93 clicks,
and a thank-you note to participants was posted on Facebook in October.
This year the company included new marketing tactics of digital display ads, search engine
marketing, and radio. Web users were exposed to 804,363 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 951 times, resulting in
a click-through rate of 0.12%. Search engine marketing displayed Idaho Power’s Irrigation Peak
Rewards program near the top of the search results with the paid search terms when
customers searched for Irrigation Peak Rewards and demand response terms. These ads
received 13,503 impressions and 312 clicks. February through May, the company ran 986 radio
ads promoting the Irrigation Peak Rewards program. The 30-second spots ran in Boise and
eastern and southern Idaho on a variety of stations, including news/talk, sports, classic rock,
adult hits, and country.
See the Irrigation Sector Overview section for additional marketing activities.
Cost-Effectiveness
Idaho Power determines cost-effectiveness for its demand response programs using the
approved method for valuing demand response under IPUC Order No. 35336 and approved by
the OPUC on February 8, 2022, in Docket No. ADV 1355. Using financial and avoided cost
assumptions from the 2021 Integrated Resource Plan, the defined cost-effective threshold for
operating Idaho Power’s three demand response programs for the maximum allowable
60 hours is $84.57 per kW under the current program parameters.
The Irrigation Peak Rewards participants were dispatched for 4 events, resulting in 39 event
hours and achieving a maximum demand reduction of 187.7 MW with a maximum potential
capacity of 252.1 MW. The total expenses in 2023 were $8.3 million and would have been
approximately $10.7 million if the program had been operated for the full 60 hours. Using the
potential cost and the maximum potential capacity results in a cost of $42.57 per kW,
which shows the program was cost-effective.
A complete description of cost-effectiveness results for Idaho Power’s demand response
programs is included in Supplement 1: Cost-Effectiveness.

Evaluations
To evaluate the program each year, Idaho Power prepares an Irrigation Peak Rewards program
Report that presents load reduction calculations and analysis, and results from the program
season. See Supplement 2: Evaluation for the 2023 report. A brief overview of the program
results is provided in this section.
A realization rate is used to measure the program’s potential performance if an all-group event
were to be called on any day during the season. This rate reflects the load that is on and
available for shutoff during a demand response event. The realization rate percentage includes
the expected event performance loss due to factors such as device failures and opt-outs. For
the 2023 season, these factors combined to an average realization rate reduction of 11.3%.
On July 6, 2023, the program achieved its highest potential, with a realization rate of 66.8% and
a peak potential reduction of 252.1 MW for the season. The realization rate is typically the
highest at the end of June and the beginning of July when a larger percentage of irrigation
pumps are operating nearly 24 hours per day, seven days per week. Later in the season,
when many pumps are not operating due to crop maturity and reduced watering demands, the
realization rate is lower.
A breakdown of the load reduction for each event day and each event hour for the 2023
program season, including line losses, is shown in Table 31.

Figure 25 shows the total hourly system load for all participants for the 24-hour period on
August 1, 2023. A reduction in system demand during the active event period from hour ending
at 4 through hour ending at 10 p.m. is clearly shown on the graph; the gradual drop and
subsequent rise in system load is due to the staggered start/end times for the four groups
participating. Maximum demand reduction occurred during the hour ending at 7 p.m., when all
groups were shut down. The small system load shown for that hour is attributed to opt-outs
and load left on during the event.

2024 Plans
For the 2024 program season, all irrigation customers will receive a comprehensive enrollment
packet containing an informational brochure, enrollment worksheet and a contact worksheet.
For all new pump signups, a demand response unit will need to be installed by a contracted
electrician prior to the program season.
Idaho Power will have an informational booth at the local 2024 Ag Expos including Western,
Eastern, and Southern. The Irrigation Peak Rewards program will be the focus of in-person
workshops presented by Idaho Power ag reps in winter 2024. For the upcoming season,
Idaho Power will continue its focus on retaining currently enrolled participants and will consider
using email marketing, radio, paid search, digital display, and other new tactics to boost
program enrollment. The ag reps will continue to remind and inform customers and encourage
program participation in person and by phone.

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.
Remodels continued to incorporate energy efficiency measures, such as lower partitions for
better transfer of daylight, transom lighting, and automated lighting controls.
The CHQ building also participated in the Flex Peak Program again in 2023 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 minimal participation in the LEEF offering.
In 2023, Idaho Power received five LEEF applications. They were generally related to home
equipment replacement requests for items, such as windows, water and space heating systems,
and appliances. The applications were reviewed, and the products referenced in the submittals
were found to be standard, widely available products, and therefore not appropriate for LEEF.
A residential program specialist followed up with the applicants to provide information on
incentives currently available through Idaho Power’s H&CE Program.
Energy Efficiency Advisory Group (EEAG)
Formed in 2002, EEAG provides input on enhancing existing DSM programs and on
implementing energy efficiency programs. Currently, EEAG consists of 13 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,
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 2023, four EEAG meetings were held on February 8, May 10
(virtual meeting), August 17, and November 8. 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 programs and expenses, 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.
Throughout 2023, Idaho Power relied on input from EEAG on existing and potential new DSM
programs. For complete meeting notes, see Supplement 2: Evaluation.
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 and Avista Utilities continued working with a third-party marketing firm on a
project that began in 2020 to explore potential opportunities to accelerate market
transformation; the goal is to benefit customers in both utilities’ service areas beyond what
NEEA is currently providing. This work resulted in a market transformation pilot that began in
2021 for DHPs in both Idaho Power’s and Avista’s service areas. The pilot was completed in
2023 and the results will be reviewed in 2024. A copy of the report is included in
Supplement 2: Evaluation.
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.

Idaho Power participates in NEEA with funding from the Idaho and Oregon Riders. The current
NEEA contract is for the five years from 2020 to 2024. NEEA categorizes the savings 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 to be co-created
savings. The current contract commits Idaho Power to paying NEEA a total of $14.7 million,
or approximately $2.9 million annually.
In 2023, 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 participated in the two overarching coordinating
committees, the RPAC, Cost-Effectiveness and Evaluation Advisory Committee (CEAC), Regional
Emerging Technology Advisory Committee (RETAC), and the Idaho Energy Code Collaborative.
The company also participated in NEEA’s initiatives, including the Commercial Building Stock
Assessment (CBSA), Residential Building Stock Assessment (RBSA), and SEM.
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.
Links to these and other reports mentioned below are provided 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.
NEEA Marketing
To support NEEA efforts, Idaho Power educated residential customers on Heat Pump Water
Heater (HPWH) and DHPs and educated commercial customers and participating contractors on
NXT Level Lighting Training and LLLC.
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 its main
Retrofits and Lighting web pages. The company also posted about LLLCs on LinkedIn in May.
NEEA Activities: All Sectors
For the 2020 to 2024 funding cycle, NEEA and its funders have reorganized the advisory
committees into two coordinating committees: the Products Coordinating Committee and the
Integrated Systems Coordinating Committee. Additionally, NEEA and its funders form working
groups as needed in consultation with the RPAC. The RPAC will continue, as well as the
RECEIVED

Cost-Effectiveness and Evaluation Advisory and the RETAC committees. The Idaho Energy Code
Collaborative will also remain intact.
The company currently has representation on both coordinating committees.
These committees provide utilities with the opportunity to give meaningful input into the
design and implementation of NEEA initiatives, as well as to productively engage with
each other. Quarterly meetings were held in 2023 for both committees, and working
groups were formed by the coordinating committees to focus on topics relevant to all sectors,
as described below.
Cost-Effectiveness and Evaluation Advisory Committee
The advisory committee 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.
The CEAC met in November 2023 to discuss the results and recommendations from the
independent third-party evaluation of NEEA’s impacts within the State of Idaho. The evaluation
was conducted on behalf of Avista and Idaho Power. While NEEA noted that several of the
recommendations could be accommodated with minimal impacts, the recommendation
regarding evaluating NEEA’s influence on codes needed to be vetted with the CEAC due to its
impacts to other utilities in the region. NEEA presented its proposed process and timeline to
meet this recommendation and will update CEAC throughout 2024.
Idaho Energy Code Collaborative
Since 2005, the State of Idaho has been adopting a state-specific version of the International
Energy Conservation Code (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. NEEA facilitates the group, 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 stakeholders to increase energy code
knowledge and compliance. Idaho Power is an active member.
The Idaho Energy Code Collaborative provided statewide resources to builders and related
stakeholders in support of the current building energy codes. The collaborative also provided
resources to address the Idaho governor’s executive order 2020-01: Zero-Based Regulation
initiative. The goal of this initiative was to reduce state regulation which involved the review of
proposed revisions to Idaho’s IDAPA 24.39.30, Building Code Rules. Subject matter experts

within the collaborative provided detailed evaluations to stakeholders to convey the
implications of the proposed revisions. Guidance was provided to the administers of the
initiative: the Division of Occupational and Professional Licenses and the Idaho Building
Code Board.
Other resources supporting current codes included monthly 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 (RETAC)
Idaho Power participated in the RETAC, which met quarterly in 2023 to review RETAC’s
emerging technology pipeline, developed with assistance from the BPA, NEEA, and the NWPCC.
Throughout 2023, RETAC focused primarily on space-heating and water-heating products for
residential and commercial markets. The technologies for these products centered on heat
pumps. RETAC discussed the current state of the technologies and their associated gaps and
issues. Other meeting topics included smart home systems, switched reluctance motors,
smart valves, dual fuel heat pumps, and microgrid pilots. This work will continue in 2024.
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 2023, RPAC conducted four quarterly meetings, three of which were virtual and one of which
was hybrid. Throughout 2023, RPAC received updates of savings forecasts, portfolio priorities,
and committee reports.
In the first regular quarterly meeting on February 27, NEEA staff provided an annual charter
review, shared out results of the HPWHs Boring But Efficient campaign, updated the committee
on portfolio status and priorities and variable speed heat pumps.
On May 18, NEEA staff provided an Efficiency Exchange Conference recap and updates on the
HPWH Consumer Consideration Marketing Campaign, business planning, and the Federal
Funding Coordination Workgroup. They provided a Market Transformation refresher and a
review of the portfolio reforecast. They provided updates on the Variable Speed Heat Pumps
program and on NEEA’s Manufactured Homes program.
At the August 29 meeting, NEEA provided an update on the HPWH Marketing Campaign timing,
2024 operations planning, and business planning. They continued with a Market

advancing the Advanced Heat Pumps Program to the market development phase. Unanimous
consent was achieved by all RPAC members present and/or casting votes electronically.
NEEA also provided workgroup updates on Federal Funding Coordination, Dual Fuel Products,
and Dual Fuel Measurement Methodology.
At the November 2 meeting, NEEA provided updates on the HPWH Marketing Campaign timing,
coordinating committees, and the Federal Funding Coordination Workgroup.
NEEA Activities: Residential
NEEA provides BetterBuiltNW online builder and contractor training and manages the regional
homes database, AXIS.
Residential Building Stock Assessment (RBSA)
The RBSA is a study 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. NEEA began work on the
RBSA in mid-2020.
Idaho Power participated in monthly workgroup 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 continued through 2022. For residential customers who chose to participate,
the third-party contractor scheduled a site visit with a field technician who collected
information on the home’s characteristics. While site visits for single-family homes were
completed in 2022, NEEA conducted field work for multifamily buildings through quarter 3
of 2023.
Due to delays in receiving the demographic and housing characteristics file from the 2020 U.S.
Census as well as challenges in recruiting multifamily tenants, completion of the study has been
delayed. A final report will be available by quarter 2 of 2024.
NEEA Activities: Commercial/Industrial
NEEA continued to provide support for C&I energy efficiency activities in Idaho in 2023,
which included partial funding of the IDL for trainings and additional tasks.
Commercial Building Stock Assessment (CBSA)
NEEA began work on the CBSA in 2022. The CBSA is a study conducted approximately every
five years, and the information is used by utilities in the Pacific Northwest and the NWPCC to
determine load forecast and electrical energy-savings potential in the region.

For commercial customers who choose to participate in the study, the third-party contractor
schedules a site visit with a field technician who collects information on equipment and building
characteristics that affect energy consumption. This includes HVAC equipment, lighting,
building envelope, water heating, refrigeration and cooking, computers and miscellaneous
equipment, and cooling towers.
Beginning in August 2022, Idaho Power staff participated in the monthly working group.
The CBSA is still in the early design phase of the study, thus the objectives and priorities are still
being determined. A request for proposal to select a contractor was issued in early 2023 to
select a firm to lead the study and a second RFP was issued in late 2023 to select a firm to
provided engineering support. Site visits for the study are planned for 2024 through 2025.
The report is slated to be released in 2026.
Very High-Efficiency Dedicated Outside Air Systems (DOAS)
NEEA’s High-Performance HVAC program focused on design of market intervention strategies
based on market and field research associated with very high efficiency DOAS. Very high-
efficiency DOAS pairs a very high-efficiency heat/energy recovery ventilator (HRV/ERV) type of
DOAS with a high-efficiency heating and cooling system, while following set design principles
that maximize efficiency. NEEA created the Energy Modeling Guide for Very High Efficiency
DOAS and Calibrated Energy Savings for Very High Efficiency DOAS in Multi-Family Housing in
2023. Additional resources for utilities are provided on the BETTERBRICKS website.
Luminaire Level Lighting Controls (LLLC)
Throughout 2023, NEEA engaged with key manufacturers and their sales channels to encourage
promotion of LLLC to their customers and projects. NEEA continued to partner with utilities to
offer trade ally training opportunities for awareness and increased understanding of Networked
Lighting Controls (NLC)/LLLC systems. Two of the training classes were held in Idaho Power’s
service area, with 18 trade allies receiving NLC/LLLC training.
NEEA continued to offer a variety of LLLC educational resources for use by utilities and their
customers and trade allies. These materials are found at betterbricks.com. In addition, NEEA is
actively working with utilities in the Pacific Northwest to develop case studies of commercial
buildings that incorporated LLLC.
NEEA Funding
In 2020, Idaho Power and NEEA commenced a five-year agreement for the 2020 to 2024
funding cycle. 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. 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 2023, Idaho Power paid $2,726,302 to NEEA: $2,589,987 from the Idaho Rider for the Idaho
jurisdiction and $136,315 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 2023 will be released later in 2024. Preliminary estimates reported by
NEEA indicate Idaho Power’s share of regional market transformation savings as 23,914 MWh.
These savings are reported in two categories: 1) codes-related and standards-related savings
of 20,665 MWh (86%) and 2) non-codes-related and non-standards-related savings of
3,249 MWh (14%).
In 2022, NEEA changed its savings methodology for reporting state codes savings. Because code
adoption varies between states, NEEA transitioned to report energy savings for state building
codes using a state allocation approach, as the funder share allocation methodology no longer
provided a reasonable representation of code savings occurring in a funder’s service area.
Previously, NEEA used the funder share allocation methodology for non-codes-related savings.
Idaho Power requested that non-code savings use the service area allocation approach. While
NEEA has committed to providing the final 2023 savings using the service area methodology,
these preliminary savings use partial 2023 data supplemented with 2022 data to approximate
trends and local program incentives specific to Idaho Power’s service area.
In the Demand-Side Management 2022 Annual Report, preliminary estimated savings reported

•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 2023, Idaho Power
staff participated in RTF meetings as a voting member and is represented on the RTF Policy
Advisory Committee.
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 2023.
Residential Energy Efficiency Education Initiative
Idaho Power recognizes the value of general energy efficiency awareness and education in
creating behavioral change and customer demand for, and satisfaction with, its programs.

Customer Education and Marketing
Idaho Power looks for ways to emphasize energy efficiency education in its Connections
newsletter, bill inserts, and digital channels. In addition, the company has developed a library of
Energy Efficiency Guides and other collateral focusing on various audiences and subject matter.
In 2023, REEEI and Idaho Power’s Corporate Communications department completed a
comprehensive review of Idaho Power’s educational materials and distribution channels,
looking for additional opportunities. Following the review, the company determined that a 46%
decline in newspaper distribution between 2021 and 2023 in the communities served
(Table 32), as well as the desire to meaningfully engage the greatest number of customers,
suggested an adjustment to the production cadence and distribution channels for the Energy
Efficiency Guides.

With the goal of distributing up-to-date seasonal energy efficiency education to the widest
range of customers, Idaho Power decided to produce a new guide every nine months,
creating the opportunity for an updated fall, winter, spring, and summer guide every third year.
Because of the overall decline in print media’s circulation, the primary distribution channel was
shifted from newspapers to an online resource—although a hard copy continued to be available
for events and via U.S. mail upon request. The first fall-themed Energy Efficiency Guide was
published in October 2023. The guide focused on information such as weatherizing homes for
winter comfort and maximum savings, how to choose the right light for your home, outdoor

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 building practices and strategies benefit the business and the customer.
In 2023, Idaho Power entered into an agreement with the IDL to perform the tasks and services
described below.
Foundational Services
The goal of this task is 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
RECEIVED

Other Programs and Activities
Page 170 Demand-Side Management 2023 Annual Report
•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
The IDL provided technical assistance on 18 new projects in Idaho Power’s service area in 2023:
15 Phase I projects, three Phase II projects, and no Phase III projects. Eight of the projects were
on new buildings, nine were on existing buildings, and one was general design assistance.
The number of projects increased by two compared to 2022. The related report is in the IDL
section of Supplement 2: Evaluation.
Lunch & Learn
The goal of the Lunch & Learn task is to educate architects, engineers, and other design and
construction professionals about energy efficiency topics through a series of educational
lunch sessions.
In 2023, the IDL provided 20 in-person technical training lunches. A total of 172 architects,
engineers, designers, project managers, and others attended.
The topics of the lunches (and the number performed of each) were: The Architect’s Business
Case for Energy Performance Modeling (5); Daylighting Multipliers—Increasing Daylighting
Harvesting Efficiency (2); Air Infiltration and Passive Systems (3); Luminaire Level Lighting
Controls (2); High-Performance Classrooms (3); The Future of Lighting Controls (1); HVAC Load
Calculations—Tips & Tricks (2); and ASHRAE Standard 209 Energy Modeling (2). The related
report is in the IDL section of Supplement 2: Evaluation.
Building Simulation Users Group (BSUG)
The goal of this task is to facilitate the Idaho BSUG, which is designed to improve the energy
efficiency related simulation skills of local design and engineering professionals.
In 2023, six BSUG sessions were hosted by the IDL. All sessions were hosted in a hybrid format
in which participants could choose to join in person or virtually. The sessions were attended by
155 professionals. Evaluation forms were completed by attendees for each session. Analyzing
results from the first six questions that rated the sessions on a scale of 1 to 5, with 5 being
“excellent” and 1 being “poor,” the average session rating was 4.41 for 2023. 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 3.33 for 2023.
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.

Energy Resource Library (ERL)
The ERL gives customers access to resources for measuring and monitoring energy use on
various systems. The goal of this task is 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 2023, 16 new
tools were added to replace old data logging models, current transformers, air-quality sensors
to complete tool kits, and added accessories for kits. 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. A contactless
pick-up and drop-off system is available if desired.
In 2023, loan requests totaled 30 with 29 loans completed and one on-going. Loans were made
to nine different locations and 14 unique users, four of which were new ERL users. The majority
of tools were borrowed for principal investigations or audits, although loans were also made for
determining baselines before energy efficiency measures were implemented. Tools were also
used to verify energy efficiency measures. The ERL web page recorded 5,220 visits in 2023
compared to 2,768 visits in 2022. The related report is in the IDL section of Supplement 2:
Evaluation.
Digital Design Tools Update
Over the years, the IDL has developed several digital design tools to assist local firms.
These tools require updating over time. In 2023, 17 tools were hosted on the IDL website and
made available for use and download serving as a one-stop resource for engineers and
architects for early design considerations. IDL provided priority for each tool and will update in
future tasks. Work in 2023 was primarily focused on developing visualization tools for CBECS
2018 data that was released in late 2022 and development of an Indoor Air Quality tool.
The related report for this task is in the IDL section of Supplement 2: Evaluation.
Fan Savings from UV Lamps
Fan Savings from UV Lamps is a new task for 2023 that will be continued in 2024. In-duct
Ultraviolet Germicidal Irradiation (UVGI) prevents microbial growth on cooling coils, which can
reduce fan energy and can result in net energy savings depending on the building type and
airflow. Energy savings are a result of cleaner cooling coils having less of a pressure restriction
that the fan must overcome. Efforts for 2023 included the research of potential impacts from
UVGI implementation and attempts at logging data between identical equipment, with and
without the UVGI technology installed. Due to logging equipment difficulties, the equipment
logging will take place in 2024 with support from a local engineering firm.

CONCLUSIONS
This DSM report provides a summary of activities performed by Idaho Power to offer DSM
programs to all its customers throughout 2023. Programs are generally designed to educate,
inform, and/or reward customers.
The savings from energy efficiency programs, including the estimated savings from NEEA,
were 139,683 MWh, and the energy efficiency portfolio was cost-effective from all three
benefit/cost methodologies (UCT, TRC, and PCT).
Idaho Power successfully operated its three demand response programs in 2023, with total
demand response capacity approximately 316 MW and an actual max load reduction of
240 MW.
The DSM programs are carefully managed and monitored for ways to improve savings,
cost-effectiveness, and value to the customer. Three energy efficiency programs were closed in
2023, either because rising costs have impacted cost-effectiveness or because market trends
have lessened the savings potential of the offerings and measures. One new program designed
for multifamily projects was introduced in 2023, to reach customers that do not easily fit within
other residential or commercial programs.
Idaho Power’s collaboration with multiple stakeholders lays the groundwork for building a
more energy-efficient future with the long-term goal of permanently changing the
existing market.
This DSM 2023 Annual Report satisfies the reporting obligation set forth by IPUC Order
No. 29419 in Case No. IPC-E-03-19.

a Levelized Costs are based on financial inputs from Idaho Power’s 2021 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. Dollars are rounded to nearest whole unit, which may result in minor rounding differences.
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 7.6% peak loss assumptions. Maximum actual demand reduction and maximum demand capacity.
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 0.44% to avoid double counting of savings in other energy efficiency programs.
3 Savings are preliminary estimates provided by NEEA. Final savings for 2023 will be provided by NEEA April 2024.
