EXECUTIVE SUMMARY
Rocky Mountain Power is a multi-jurisdictional electric utility providing retail service to
customers in Utah, ldaho, and Wyoming. Rocky Mountain Power, a division of PacifiCorp, serves
approximately 84,504 customers in southeastern ldaho. 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 ("lRP"1r 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 Powe/s energy efficiency programs.a
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.s
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 L,2O2O through
December 3L,2020. Rocky Mountain Power, on behalf of its customers, invested S5.4 million in
energy efficiency resource acquisitions during the reporting period. The investment yielded
approximately 229 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 S1.4 million.6

LOW I NCOME WEATHERIZATION
Progrom Destiption
The Low-lncome 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 ldaho Community Action Partnership, lnc. ("EICAP") and
South Eastern ldaho Community Action Agency ("SEICAA') to provide services. The two agencies
receive federal funds allocated to the ldaho Department of Health and Welfare ("|DHW") and
administered by the Community Action Partnership Association of ldaho ("CAPA!"). 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 tdaho Public Utilities Commission on January L6,20L9, Commission approved
reimbursement of up to 100% of related installed costs of ductless heat pumps, effective March
6,2OL9. Agencies cover remaining costs with the funding received by IDHW.
The Low-lncome Weatherization program did not pass the PTRC with a cost benefit ratio of 0.74
for 2O2O. Under direction of Case No. GNR-E12-01, Low lncome Weatherization program uses
the 10 percent conservation adder to the tota! resource cost test as its primary cost test.
Program Performonce ond Major Achievements in 2020
. In 2020, the program achieved savings at site of 37,245 kilowatt hours. Number of homes served 23
Commission Order No. 32788 authorized the Company to fund the Low-lncome Energy
Conservation Education with 525,000 annually. These education services are provided by EICAP
and SEICAA and target participants who receive Low Income Home Energy Assistance Program
("L|HEAP") funds. EICAP did not request program year ("PY") 2021funding 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 59,000 at the beginning of their 2O2Ol2o2L
LIHEAP program year. Due to COVID-l9 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-lncome
Weatherization program, other energy efficiency programs or portfolio results.

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 2.OZL 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.

Progrom Performonce and Major Achievements in 2020
ln2O2O, the program achieved gross energy savings at site of 15,991,503 kwh.
Distributed incentives of S1,998,359.
To foster continued growth and utilization of the Wattsmart Business Vendor Network
("WBVN") and to increase customer satisfaction, a full-time ldaho-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 ldaho measure
mix at the beginning of the year. ln 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 ldaho Falls Chuck-A-Rama Buffet
restaurant, which Nexant will use to train ldaho 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 ldaho.
2020 is the first full program year for ldaho's overhauled !ighting 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 ldaho's lighting market.
ldaho's first ANLC project to receive RMP incentives was completed in 2020.
SBD| had 58 installed projects, with an average kWh installed per project ol LL,47L,
average co-pay SI,L74, and the average incentive per project of 53,521.
Small Business enhanced using select contractors to offer Small Business Direct
lncentive offer.

COST EFFECNVENESS
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 too! 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 Powe/s programs is outlined below. The
primary cost/benefit test observed in ldaho is the UCT for all programs other than the Low-
lncome Weatherization program, which uses the PTRC.11
PacifiCorp Tota! Resource Test ("PTRC") is the total resource cost test with an additional
t0% 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 ("Pgf") compares the portion of the resource paid directly by
participants to the savings realized by the participants.
Ratepayer lmpact Cost Test ("RlM") 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.
11 Under direction of Case No. GNR-E-12-0L, Low lncome Weotherization program uses the 10 percent energy
conservation adder to the total resource cost test.

Portfolio-level cost effectiveness includes portfolio costs, such as the Potential Assessment and
DSM system database. Sector-level cost effectiveness, reported in the Residential and Non-
Residential sections of this report, includes sector-specific evaluation, measurement, and
verification expenditures. The Company includes quantifiable non-energy impacts at the
portfolio and residential level, as well as the Wattsmart Homes and Low-lncome Weatherization
program level.
12 Cost-effectiveness memo detail is provided in Appendix A.
13 The Low-lncome Weatherization and Wattsmart Homes programs include non-energy impacts.
14 A "Pass" designation equates to a benefit cost ratio of 1.0 or better.
1s Low-lncome Weatherization conservation education funding is excluded from the program level cost-effectiveness
testing, but is included in the portfolio and residential sector cost-effectiveness.
16 Participants in Home Energy Reports do not incur costs; therefore, N/A is appropriate.
17 Participants in Low lncome Weatherization do not incur costs; therefore, N/A is appropriate.
