PacifiCorp rates in Utah, Wyoming, Oregon and Washington

Rocky Mountain Power and Pacific Power prices by state

The two brands are one company. Rocky Mountain Power is the name PacifiCorp uses in Utah and Wyoming, Pacific Power the name in Oregon and Washington. EIA counts all four under the same utility number (14354) but reports each state separately, because each state regulator sets its own rates. The figures below are average revenue per kWh: what bundled residential customers paid in total, fixed charges and fuel adjustments included, divided by the kWh they used. They are averages, not the price on a tariff sheet.

For calendar 2025, the four averaged 14.26¢ per kWh together, weighted toward Utah, where 969,000 of the company's 1.8 million¹ residential customers live:

• Rocky Mountain Power in Utah: 13.52¢ per kWh, 51st lowest of 177 among the 177 US utilities with 100,000 or more residential customers;
• Pacific Power in Washington: 14.33¢ per kWh, 8.8% above the Washington average;
• Rocky Mountain Power in Wyoming: 15.13¢ per kWh, 13.2% above the Wyoming average;
• Pacific Power in Oregon: 15.18¢ per kWh, 1.8% below the Oregon average¹.

Measured against investor-owned utilities nationwide, all four averaged less in 2025: Utah's average was 24.0% below the national average for investor-owned utilities, Wyoming's 14.9% below the national average for investor-owned utilities, Oregon's 14.6% below the national average for investor-owned utilities. Inside their own states the picture reverses. Among utilities with 10,000 or more residential customers, PacifiCorp ranked 2nd highest of 13 in Utah, 2nd highest of 7 in Wyoming, 2nd highest of 19 in Oregon and 5th highest of 28¹ in Washington. The state pages for Utah, Wyoming, Oregon and Washington list the utilities that averaged less.

The last 12 months reorder the four

EIA's monthly survey (EIA-861M, months since January 2026 preliminary) gives a more recent reading. For the 12 months from September 2025 to August 2026, the averages were 15.60¢ per kWh in Wyoming, 15.38¢ per kWh in Washington, 14.85¢ per kWh in Oregon and 13.68¢ per kWh⁴ in Utah. Oregon, the highest of the four in 2025, came in below its calendar-year average; the other three came in above theirs, Washington by the widest margin.

Compared with the same month a year earlier, the latest reading is lower. In August 2026⁵, residential customers paid an average of 14.70¢ per kWh in Oregon (−5.1% on August 2025), 14.34¢ per kWh in Wyoming (−4.7%), 13.81¢ per kWh in Utah (−4.3%) and 14.81¢ per kWh in Washington (−0.1%⁴). One month reflects that month's use and any adjustments billed in it, so the 12-month figure is the steadier guide.

Washington's 2025 jump

All four averages rose from 2024 to 2025: Utah +8.0%, Oregon +8.3% and Wyoming +12.6%. Washington's rose 29.3%, from 11.08¢ per kWh to 14.33¢ per kWh, moving it from the cheapest of the four in 2024 to second-cheapest. Its average bill went from $130.84² to $166.84¹ a month.

The increase follows a two-step rate plan. In March 2024 the Washington Utilities and Transportation Commission approved a settlement in PacifiCorp's general rate case, with one increase from March 2024 and a second from March 2025; 2025 was the first calendar year with the second step in place for most months.

One power supply, divided among the states

Because one company serves all these states, its costs have to be divided among them, and how that is done is itself a regulatory decision. In December 2025 the Washington commission approved a plan to share costs among all six states the company serves, called the 2026 Protocol, replacing the method used for Washington until then. The same decision approved, with conditions, the removal of coal from Washington customers' rates, as an earlier order required. The commission said the new method lowers costs for Washington customers compared with the old one. The other two states in that plan, California and Idaho, are smaller PacifiCorp service areas and are not compared on this page.

Rate cases, adjustment riders, fixed charges and time-of-use hours are on the dockets of the four commissions: the Public Service Commission of Utah, the Wyoming Public Service Commission, the Oregon Public Utility Commission and the Washington Utilities and Transportation Commission. EIA's averages show the combined result of those decisions, not their parts.

Why Washington bills are the largest

Price per kWh explains little of the gap in bills. In 2025, Pacific Power's Washington homes used 1,164 kWh a month on average and paid $166.84. Rocky Mountain Power's Utah homes used 746 kWh and paid $100.84; Wyoming homes used 710 kWh and paid $107.47, the second-lowest bill despite one of the higher prices. Oregon sat between them: 877 kWh and $133.04¹.

The seasons split the company in two. In the Pacific Northwest, use peaks in winter: over the 12 months from September 2025 to August 2026, Washington homes used 1,699 kWh in January 2026, for an average bill of $263.65, against a low of $105.48 in April 2026. Oregon's peak came in January 2026 (1,183 kWh, $171.07). In the Mountain West the peak is in summer: Utah homes used 1,308 kWh in July 2026 and paid $176.54, against $75.68 in April 2026. Wyoming's bills swung the least of the four, from $90.68 in September 2025 to $131.01 in January 2026, although its use peaked in July 2026⁴.

Smart meters in Oregon and Utah, not in Washington or Wyoming

Meter technology differs sharply within the one company. In 2025, 98.6% of residential meters in Oregon and 97.6% in Utah were advanced (AMI) meters, against 0.0% in Washington and 0.0% in Wyoming. Time-varying pricing was rare everywhere: 0.4% of residential customers in Oregon, 0.3% in Utah, 0.1% in Washington and 0.0%⁶ in Wyoming were enrolled.

Rooftop solar is most common in Utah, with 78,575 net-metered residential installations in 2025, or 81.1 per 1,000 customers. Oregon had 41.3 per 1,000, Washington 32.3 and Wyoming 10.3⁶.

Oregon's outage minutes

Counting major events, the average Pacific Power customer in Oregon was without power for 385 minutes in 2025, more than the Oregon average of 256 minutes. Without major event days the figure was 104 minutes, in the same range as Utah (102 minutes) and Wyoming (91 minutes); Washington's was 58 minutes³. Most of Oregon's outage time in 2025 therefore came on major event days. All four report under IEEE 1366. Separately, the Oregon commission lists Pacific Power's wildfire mitigation plans and dockets on its wildfire page.
