b'addition to its company-owned resources, IdahoCalifornia Independent System Operator (CAISO) Powers supply-side portfolio includes severallaunched Western Regional Energy Imbalance Market long-term contracts with wind, solar, biomass, small(EIM). PaciCorp operates under the name Rocky hydro, and geothermal facilities. Among these areMountain Power (RMP) in Idaho, Utah, and Wyoming, contracts with 134 PURPA projects, totaling 1,149and serves 77,000 customers in 14 Idaho counties.4MW, of which 627 MW are wind generation and 316 MW are solar generation.4 PaciCorp utilizes approximately 16,500 miles of transmission line, 64,000 miles of distribution line, and In March 2019, Idaho Power announced a goal to900 transmission substations to serve its customers. provide 100 percent clean energy by 2045. TheThe corporation owns 66 generating plants with utility expects to accomplish this goal through10,880 MW of net generation capacity, including coal, three primary strategies. First, in 2022, Idaho Powerhydroelectric, natural gas, wind, and geothermal will add 120 MW of solar PV capacity generated byresources (see Figure 10). Wind, hydro, geothermal, Jackpot Solar in Twin Falls county. Second, Idahoand other non-carbon-emitting resources currently Power plans to exit coal-red generation over themake up 30 percent of RMPs owned and contracted course of 2019-2026: it will exit from its share ofgenerating capacity. PaciCorp owns 2,222MW of North Valmy Unit 1 by year-end 2019, Boardmanwind generation capacity and has long-term power by year-end 2020, a Jim Bridger unit during 2022,purchase agreements for 1,686 MW from wind North Valmy Unit 2 by year-end 2025, and a secondprojects owned by others.4Jim Bridger unit during 2026. Third, Idaho Power is teaming up with Pacicorp and BPA to complete permit, construct, operate, and maintain a new, single-circuit 500-kV transmission line approximately 300-miles long between the proposed Longhorn Station near Boardman, Oregon, and the existing Hemingway Substation in southwest Idaho. The feat is called the Boardman to Hemingway (B2H) Project and will provide many benets, including the following: greater access to the Pacic Northwest electric market to economically serve homes, farms, and businesses in Idaho Powers service area, improved system reliability and resiliency, reduced capacity limitations on the regional transmission system as demands on the system continue to grow, exibility to integrate renewable resources and more eciently implement advanced market tools, such as the Energy Imbalance Market (EIM).6PacifiCorp / Rocky Mountain PowerPaciCorp serves more than 1.9 million retail customers across 141,390 square miles of service territory in California, Idaho, Oregon, Utah, Washington, and Wyoming. PaciCorp merged in 1989 with Utah Power & Light Company and was purchased by MidAmerican Energy Holdings Company in 2006, which later changed its name to Berkshire Hathaway Energy.
