PacifiCorp is an electric power company in the western United States.

PacifiCorp has two business units:

  1. Pacific Power, a regulated electric utility with service territory throughout Oregon, northern California, and southeastern Washington.
  2. Rocky Mountain Power, a regulated electric utility with service territory throughout Utah, Wyoming, and southeastern Idaho.

PacifiCorp operates one of the largest privately held transmission systems in the U.S. within the western Energy Imbalance Market.

In 2001, PacifiCorp was purchased by Scottish Power. Since 2006, PacifiCorp has been a wholly owned subsidiary of Berkshire Hathaway Energy (formerly MidAmerican), itself an affiliate of Berkshire Hathaway.

PacifiCorp is currently headquartered in the Lloyd Center Tower[4] at 825 N.E. Multnomah Street, Portland, Oregon, in the Lloyd District. Pacific Power is also headquartered in the same building. Rocky Mountain Power is headquartered in Salt Lake City, Utah.

Pacific Power and Rocky Mountain Power combined serve over 1.6 million residential customers, 202,000 commercial customers, and 37,000 industrial and irrigation customers - for a total of approximately 1,813,000 customers. The service area is 143,000 square miles (370,000 km2). The company owns and maintain 16,500 miles (26,600 km) of long distance transmission lines, 64,000 miles (103,000 km) of distribution lines, and 900 substations.

In 1977, PacifiCorp spun off its coal mining interests into a mining company known as NERCO, which was eventually listed on the New York Stock Exchange and ranked as high as 353 on the Fortune 500 list of the largest American companies. Through its majority interest in NERCO, PacifiCorp was involved in the mining of coal, oil, natural gas, gold, silver, and uranium. PacifiCorp still owned 82% of NERCO in 1993, when it was acquired by the mining giant Rio Tinto Group.[5]


PacifiCorp was formed in 1910 from the merger of several small electric companies in eastern Oregon and Washington to form the Pacific Power & Light Company. It gradually expanded its reach to include most of Oregon, as well as portions of California, Washington and Wyoming. In 1984, it reorganized itself as a holding company, PacifiCorp, headquartered in Portland with Pacific Power as its main subsidiary.

In 1987, PacifiCorp acquired Utah Power & Light.[6] Headquartered in Salt Lake City, Utah Power had been formed in 1912 from the merger of four electric companies in Utah, Idaho and Wyoming. In 1881, one of those companies made Salt Lake City the fifth city in the world with central station electricity.

After the merger, Pacific Power and Utah Power operated as divisions of PacifiCorp. In a July 2006 reorganization, Pacific Power's territory in central and eastern Wyoming was merged with the Utah Power territory to form Rocky Mountain Power.[7]

Pacific Power

Pacific Power serves customers in Washington, Oregon and California. Major cities served include:

As of December 31, 2009, Pacific Power serves 555,070 customers in Oregon, 126,665 customers in Washington, and 45,148 customers in California.[8]

Rocky Mountain Power

Rocky Mountain Power serves customers in Idaho, Utah, and Wyoming.

Major cities served include:


Ammon, Lava Hot Springs, Malad City, Montpelier, Preston, Rigby, Rexburg, Saint Anthony, Shelley


Rocky Mountain Power serves most major cities in Utah, with the following exceptions:

Bountiful, Kaysville, Lehi, Logan, Provo, Murray, Monroe, Monticello, Springville, St. George


Buffalo, Casper, Cody, Douglas, Evanston, Green River, Kemmerer, Lander, Laramie, Rawlins, Riverton, Rock Springs, Thermopolis


As of May 1, 2007, Rocky Mountain Power serves approximately 758,000 customers in Utah, 129,000 customers in Idaho, and 67,000 customers in Wyoming.

Net metering

In November 2017, Rocky Mountain Power made a deal with the state's utility authorities to phase out net metering. The program was paying customers who generated their own electricity with rooftop solar panels the residential rate for their excess energy that got sent back into the energy grid. As of August 2018, new rooftop solar installations were down 23 percent, likely due to the cancellation of the net metering program. New solar customers are paid by a transitional program that pays slightly less than the residential rate until 2033. People who installed solar panels prior to November 2017 are grandfathered at the previous rates until 2035.[9]


Utah Power and Light (UP&L) was organized on 6 September 1912 as a subsidiary of a large holding company, Electric Bond and Share Company (EBASCO) of New York. Within four years of its organization, UP&L had purchased twenty-seven other electric companies in the general Utah area, and eventually absorbed more than one hundred thirty.

Pacific Power & Light was formed in 1910 from the merger of several financially troubled utilities in Oregon and Washington. In 1954, Pacific Power & Light merged with the Mountain States Power Company, essentially doubling the company's service area. In 1961, the company purchased the California Oregon Power Company, extending its service into southern Oregon and northern California.[10]

PacifiCorp owns, maintains and operates generation assets and manages the commercial and trading operations of the company. PacifiCorp owns 68 generating plants with a capacity of 9,140 megawatts. 70.6% of the generation is from thermal sources (i.e., coal or natural gas), 6.7% from hydroelectric sources, and 0.2% from renewable sources. 22.5% of PacifiCorp's generation is purchased from other suppliers or under contracts.

Generation resources

In these tables of generation properties owned or partially-owned by PacifiCorp, total capacity is 10,556MW. Of this, 56% is coal, 24% is natural gas, 10% is hydroelectric, and 10% is renewable.

Coal mining

PacifiCorp also owns and operates several captive coal mines located at or very near some of its generation plants. In Wyoming, PacifiCorp operates and has partial interest in Jim Bridger Mine and owns the Dave Johnston Mine, which is in final reclamation. The company also owned and operated the Deer Creek Mine in Utah, near the Huntington Plant but closed it in 2015 and has a partial interest in the Trapper Mine in Colorado.

Electric vehicles

Calling it a "new era of utility involvement in transportation electrification," the Portland Business Journal in 2018 described PacifiCorp's electric vehicle promotion program as a plan that promises new electric vehicle charging sites, outreach and education efforts. The program was spawn from legislation passed in 2016 that called for more renewable energy from the state's utility companies.[11]
