Rocky Mountain Power, a division of PacifiCorp, serves approximately 86,874 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. 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 customers. 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 energy efficiency 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 customers 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, 2022, through December 31, 2022. Rocky Mountain Power on behalf of its customers, invested $7.7 million in energy efficiency resource acquisitions during the reporting period. The investment yielded approximately 16 megawatt hours (“MWh”) at generator in first-year energy savings, and approximately 3 megawatts (“MW”) of capacity reduction from 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 1 Information on PacifiCorp’s IRP can be found at https://www.pacificorp.com/energy/integrated-resource- plan.html. 2 Information on PacifiCorp’s planning process can be found at https://www.pacificorp.com/environment/demand- side-management.html under the “Rocky Mountain Power planning” section. 3 Information on program administration can be found at https://www.pacificorp.com/environment/demand-side- management.html under the “Program administration” section. 4 Information on program evaluations can be found at https://www.pacificorp.com/environment/demand-side- management.html under the “Reports and program evaluations by state” section. 5 Information on communications and outreach can be found at https://www.pacificorp.com/environment/demand- side-management.html under the “Communications and outreach” section. 6 See cost effectiveness Appendix A, UCT Net Benefits exc.

Program Performance and Major Achievements in 2022  Total savings for 2022 in MWh was 5,018, which equates to 5,018,450 in kWh savings.  In 2022 reports were initially provided to approximately 28,000, which was expanded to 41,000 customers in July 2022.  Report highlights o Individual recommendations to save energy o Insights on how customers are using energy by appliance type o Home characteristics included in report with easy access to update home profile o Monthly usage history included in reports  Online portal was improved to provide greater insights for all residential customers.  In 2022, only 0.29% of customers (190 customers) have requested to be removed from the program. Additional information on the program administration can be found on the Company’s website under the Program administration section: https://www.pacificorp.com/environment/demand-side-management.html Direct Link to Home Energy Reports program administration: https://www.pacificorp.com/content/dam/pcorp/documents/en/pacificorp/environment/dsm/idaho/Id aho_Program_Administration_Home_Energy_Reports_22.pdf Page 8 of 18 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 Southeastern Idaho Community Action Agency (“SEICAA”) to provide services. The two agencies receive federal funds allocated to and administered by the Idaho Department of Health and Welfare (“IDHW”). 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 0.95 for 2022. 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. Cost- effectiveness was partially affected by the use a single-family heat pump load profile in lieu of a single-family cooling load profile to value the timing of energy savings. Several measures installed through the program save energy throughout the year and not just the summer months, therefore a heat pump load profile was selected to reflect energy savings in non-summer months. Program Performance and Major Achievements in 2022  In 2022, the program achieved savings at site of 31,995  Number of homes served 27 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 received $16,000 program year (“PY”) 2022 funding by the beginning of their 2022/2023 LIHEAP program year. SEICAA did not request funds in 2022 as they had funds from PY 2019 and PY 2021 to spend. SEICAA did not purchase kits as they had inventory of kits purchased in 2019 to distribute. COVID-19 restrictions in operations slowed the distribution of kits in PY 2020 and PY 2021 and increased in PY 2022 Page 9 of 18 The agencies provided a conservation education curriculum to households and reported the following activities and program specifics for 2022 in Table 1 below. Table 1 2022 Conservation Education Activities $ 16,000.00 $ 0.00 $ 21,674.71 $ 0.00 $ 30,194.04 $ 20,250.00 608 45 Distribution EICAP purchased 500 kits using PY 2022 funds. The new kits include two 9W LED bulbs, a LED night light, a window insulation kit, a wall plate thermometer, a refrigerator thermometer, a freezer thermometer, five foam light switch sealing gaskets, five foam electrical outlet sealing gaskets, a furnace whistle, one 2pk wool dyer balls, a faucet aerator, and one shower timer As of December 31, 2022, EICAP has 610 kits 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 PY2022 and intends to utilize remaining PY2019 funds combined with the PY2020 and PY2021 funding to purchase new kits as well as reserve some of the funds for postage and professional fees.

Wattsmart Business is designed to influence new and existing non-residential customers to increase the efficiency of electric energy usage both through the installation of efficient equipment as well as adoption of improved energy management protocols. Qualifying measures include those which produce verifiable electric energy efficiency improvements compared to an established baseline. Wattsmart Business offerings include:  Typical Upgrades  Midstream/Instant incentives  Custom Analysis  Energy Management  Energy Project Manager Co-funding The Wattsmart Business program passed the UCT with a cost benefit analysis of 1.49. Page 11 of 18 Program Performance and Major Achievements in 2022  In 2022, the program achieved gross energy savings at site of 6,940,859 kWh.  Distributed incentives of $863,132.  To foster continued growth and utilization of the Wattsmart Business Vendor Network (WBVN) and to increase customer satisfaction, the Company continued to employ full- time outreach specialist dedicated to Idaho. This staff member provides an outreach and support role to both vendors and customers interested in lighting as well as non- lighting incentives.  In 2022, 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. In 2022, there were three premium status Wattsmart Business Vendors.  Several challenges presented themselves in 2022 leading to lower savings in the Wattsmart Business Program than in years past. o Significant supply chain disruptions had a negative effect on program energy savings achievements. o Due to supply timelines and project lifecycles, there were no large energy savings projects completed in CY 2022 by the largest industrial customers within the utility service territory. The Company expects this to be rectified in 2023 through focused outreach efforts began in 2022.

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 optouts or non-participation. For most participants, their irrigation pumps are set up with a dispatchable two-way control system giving Rocky Mountain Power control over their loads. Participants are notified four hours 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 2022. Program Performance and Major Achievements in 2022  There were 17 load control events initiated in 2022. There were 8 mandatory and 9 voluntary events.  The available load from the Irrigation Program can be utilized as reserves which provides value to the program and benefits the customer.  Customers were given a 20% incentive bonus for participation in general.  Total customers participating in the program are 154, participation sites 1,091.  Total enrolled MW (Gross -at Gen) in 2022 is 169, maximum realized MW (at Gen) is 137.

There were no battery communication failures. • New customer enrollment with batteries and new solar only installs during the same period • No commercial batteries were enrolled in the program during 2022. • During 2022 there were 486 new customers interconnected with solar with seven customers completing the enrollment process into the Wattsmart Battery Program. The enrollment application for customer generation versus the enrollment in Wattsmart Batteries is a separate unique process. It is expected many of the solar enrollments will eventually enroll in the battery program. Program Description The Wattsmart Batteries program promotes and incentivizes the installation of qualified individual batteries for system-wide integration and use for overall electric grid management. Leveraging batteries has created an opportunity to maximize renewable energy for advancing a sustainable electric grid. The batteries may be used for frequency response, peak load management, transmission relief, daily load cycling, and other smart grid applications. Batteries participating in the Wattsmart Battery Program are integrated within PacifiCorp’s Energy Management System to provide real-time grid benefits Eligible customers who participate in the program receive an enrollment incentive based on the kW size of their battery and participation commitment, and ongoing annual incentives for continued participation. The battery program passed the UCT test using a 20-year NPV because the net benefits exceeded the program costs, however, did not pass using the 1-year NPV. This is primarily due to the program having high upfront incentives and limited participation during the first year of the program.

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 • 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 lower revenue requirements while putting near-term upward pressure on the rates remaining fixed costs are spread over fewer kilowatt-hours. 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.
