EXECUTIVE SUMMARY
Rocky Mountain Power is a multi-jurisdictional electric utility providing retail service to
customers in Utah, Idaho, and Wyoming. Rocky Mountain Power, a division of PacifiCorp, serves
approximately 84,504 customers in southeastern Idaho. Rocky Mountain Power acquires energy
efficiency and peak reduction resources as cost effective alternatives to the acquisition of supply-
side resources. These resources assist in efficiently addressing load growth and contribute to the
ability to meet system peak requirements.
PacifiCorp develops an integrated resource plan (IRP)1 as a means of balancing cost, risk,
uncertainty, supply reliability/deliverability and long-run public policy goals. The IRP presents a
framework of future actions to ensure that Rocky Mountain Power continues to provide reliable,
reasonably priced service to customer. Energy Efficiency and peak management opportunities
are incorporated into the IRP based on their availability, characteristics, and costs.2
Rocky Mountain Power employs external implementers to administer its programs.3 Evaluations
for each program are performed by independent external evaluators to validate energy and
demand savings derived from Rocky Mountain Power’s energy efficiency programs.4
Rocky Mountain Power utilizes earned media, customer communications, education, and
outreach, advertising as well as program specific marketing to communicate the value of energy
efficiency, provide information regarding low-cost, no-cost energy efficiency measures and to
educate customer on the availability of programs, services, and incentives.5
This report provides details on program results, activities, and expenditures of the Customer
Efficiency Tariff Rider (“Schedule 191”) as of the reporting period from January 1, 2020 through
December 31, 2020. Rocky Mountain Power on behalf of its customers, invested $5.4 million in
energy efficiency resource acquisitions during the reporting period. The investment yielded
approximately 25.8 megawatt hours (“MWh”) at generator in first-year energy savings, and
approximately 4.64 megawatts (“MW”) of capacity reduction form energy efficiency. Net
benefits based on the projected value of the energy savings over the life of the individual
measures is estimated at $1.4 million.6

LOW INCOME WEATHERIZATION
Program Description
The Low-Income Weatherization program provides energy efficiency services through a
partnership between the Company and local non-profit agencies to residential customers who
meet the income-eligible guidelines. Services are provided at no cost to the program participants.
The Company contracts with Eastern Idaho Community Action Partnership, Inc. (“EICAP”) and
South Eastern Idaho Community Action Agency (“SEICAA”) to provide services. The two agencies
receive federal funds allocated to the Idaho Department of Health and Welfare (“IDHW”) and
administered by the Community Action Partnership Association of Idaho (“CAPAI”). Energy
efficiency measures are installed in the homes of income eligible households throughout the
Company’s service territory by EICAP and SEICAA. The Company is required to fund 85 percent of
the cost of approved measures, pursuant to Commission Order No. 32151. Under Advice No. 19-
01 filed with Idaho Public Utilities Commission on January 16, 2019, Commission approved
reimbursement of up to 100% of related installed costs of ductless heat pumps, effective March
6, 2019. Agencies cover remaining costs with the funding received by IDHW.
The Low-Income Weatherization program did not pass the PTRC with a cost benefit ratio of 0.74
for 2020. Under direction of Case No. GNR-E12-01, Low Income Weatherization program uses
the 10 percent conservation adder to the total resource cost test as its primary cost test.
Program Performance and Major Achievements in 2020
In 2020, the program achieved savings at site of 37,245
Number of homes served 23
Low Income Energy Conservation Education
Commission Order No. 32788 authorized the Company to fund the Low-Income Energy
Conservation Education with $25,000 annually. These education services are provided by EICAP
and SEICAA and target participants who receive Low Income Home Energy Assistance Program
(“LIHEAP”) funds. EICAP did not request program year (“PY”) 2021 funding by 2020-year end as
they had large inventory of kits purchased with PY 2020 funds which they planned to distribute
throughout the LIHEAP PY 2021. SEICAA received $9,000 at the beginning of their 2020/2021
LIHEAP program year. Due to COVID-19 pandemic, agencies faced challenges in their effort to
distribute/deliver conservation kits to low income customers and increased use of funds to ship
kits to program clients. While the conservation education activities do result in energy savings,
the savings are not considered when calculating the performance results of the Low-Income
Weatherization program, other energy efficiency programs or portfolios results.

Distribution
EICAP purchased 500 kits using program year 2020 funds. The new kits include three 9W LED
bulbs, 1 LED night light, a window insulation kit, a smoke detector with alkaline battery, a wall
plate thermometer, a showerhead, and a hot water gauge. Due to COVID-19, EICAP continued
distribution of their program year 2019 kits by mail as they did not interact with clients. As of
December 31, 2020, EICAP has 500 kits purchased in 2020 in their inventory.
EICAP’s program objective was to educate Rocky Mountain Power customers on how to conserve
energy through useful tips and tools to help them save year-round. They served Rocky Mountain
Power households that received energy assistance and/or requested energy conservation
education.
SEICAA did not purchase kits in 2020 and planned to utilize a portion of the PY 2021 funds to
cover the cost to ship kits purchased in 2019 to households. Once inventory has been distributed,
SEICAA will identify the remaining funds available and purchase new energy conservation kits.

Page 11 of 17
Program Performance and Major Achievements in 2020
In 2020, the program achieved gross energy savings at site of 16,991,503 kWh.
Distributed incentives of $1,998,359.
To foster continued growth and utilization of the Wattsmart Business Vendor Network
(WBVN) and to increase customer satisfaction, a full-time Idaho-based lighting staff
member was added. This staff member provides an outreach and support role to both
vendors and customers interested in lighting incentives.
Advanced Rooftop Control (ARC) HVAC measures were added to the Idaho measure
mix at the beginning of the year. In late program year, ARC incentives were expanded,
and in some cases increased, furthering vendor and customer participation in this new
offering. A video case study was filmed at an Idaho Falls Chuck-A-Rama Buffet
restaurant, which Nexant will use to train Idaho WBVN vendors on ARC technology.
In 2020, participating WBVN vendors continued receiving quarterly vendor
performance scorecards to provide timely feedback and encourage vendors to strive
to reach “Premium” status, which entitles qualifying vendors to improved visibility
and enhanced co-branding with Rocky Mountain Power. One lighting vendor achieved
Premium vendor status, the first in Idaho.
2020 is the first full program year for Idaho’s overhauled lighting incentives, designed
to encourage behaviors that move the market toward further adoption of lighting
controls, especially Advanced Networked Lighting Controls (ANLC). These represent
the next frontier of significant energy saving technologies in Idaho’s lighting market.
Idaho’s first ANLC project to receive RMP incentives was completed in 2020.
SBDI had 58 installed projects, with an average kWh installed per project of 11,471,
average co-pay $1,174, and the average incentive per project of $3,521.
Small Business enhanced using select contractors to offer Small Business Direct
Incentive offer.

PEAK REDUCTION PROGRAMS
IRRIGATION LOAD CONTROL
Program Description
The irrigation load control program is offered to irrigation customers receiving electric service on
Schedule 10, Irrigation and Soil Drainage Pumping Power Service. Participants enroll in the
program with a third-party administrator and allow the curtailment of their electricity usage in
exchange for an incentive. Customer incentives are based on the site’s average available load
during load control program hours, adjusted by opt outs or non-participation.
For most participants, their irrigation pumps are set up with a dispatched two-way control system
giving Rocky Mountain Power control over their loads. Participants are notified a day ahead of
control events and have the choice to opt-out of a limited number of dispatch events per season.
The Irrigation Load control program passed the UCT cost test for 2020.
Program Performance and Major Achievements in 2020
There were 9 load control events initiated in 2020 due to energy prices being low. Three
of the total events were voluntary.
The available load from the Irrigation Program can be utilized as reserves which provides
value to the program and benefits the customer.
The real-time Irrigation pilot continued during the 2020 season to test equipment
requirements, system responsiveness, and impact on irrigators.
Customers were given a 20% incentive bonus for participation in general.
Total customer participating in the program are 152, participation sites 1,240.

COST EFFECTIVENESS
TOTAL COST EFFECTIVENESS RESULTS BY PORTFOLIO AND PROGRAM
Program cost effectiveness is performed using a Company specific modeling tool, created by a
third-party consultant. The tool is designed to incorporate PacifiCorp data and values such as
avoided costs, and generally follows the methodology specified in California’s Standard Practice
Manual. The analysis assesses the costs and benefits of DSM resource programs from different
stakeholder perspectives, including participants and non-participants, based on four tests
described in the Standard Practice Manual (TRC, UCT, PCT and RIM) as well as an additional fifth
test, PTRC.
Each of the cost-effectiveness tests for Rocky Mountain Power’s programs is outlined below. The
primary cost/benefit test observed in Idaho is the UCT for all programs other than the Low-
Income Weatherization program, which uses the PTRC.10
9 (v) = voluntary events
10 Under direction of Case No. GNR-E-12-01, Low Income Weatherization program uses the 10 percent energy
conservation adder to the total resource cost test.
Page 16 of 17
• PacifiCorp Total Resource Test (PTRC) is the total resource cost test with an additional
10% added to the net benefit side of the benefit/cost formula to account for non-
quantified environmental and non-energy benefits of conservation resources over supply
side alternatives.
• Total Resource Cost (TRC) Test considers the benefits and costs from the perspective of all
utility customers, comparing the total costs and benefits from both the utility and utility customer
perspectives.
• Utility Cost (UCT) Test also called the program administrator cost test, provides a benefit
to cost perspective from the utility only. The test compares the total utility cost incurred
to the benefit/value of the energy and capacity saved and contains no customer costs or
benefits in calculation of the ratio.
• Participant Cost Test (PCT) compares the portion of the resource paid directly by
participants to the savings realized by the participants.
• Ratepayer Impact Cost Test (RIM) examines the impact of energy efficiency expenditures
on non-participating ratepayers overall. Unlike supply-side investments, energy efficiency
programs reduce energy sales. Reduced sales typically lowers revenue requirements
while putting near-term upward pressure on the rates remaining fixed costs are spread
over fewer kilowatt-hours.
