Idaho Power Co Electricity Rate per kWh (2024 EIA Data)

Idaho Power Co is an investor-owned electric utility that reports to the U.S. Energy Information Administration under utility number 9191. In 2024 it served 525,751 bundled residential customers in Idaho (its largest state of 2), and its average realised residential price was 11.76 cents per kWh: $679 million of residential revenue divided by 5.78 million MWh of residential sales.

Across the other sectors, Idaho Power Co's 2024 average prices were 9.15 cents for commercial customers (75,435 accounts) and 8.15 cents for industrial customers (20,187 accounts). Industrial customers paid 3.61 cents less per kWh than households, a 31% discount that is typical of high-volume, high-voltage service.

Within Idaho, Idaho Power Co ranked number 1 of 13 utilities with bundled or delivery service by residential accounts served (525,751) and accounted for 58.76% of the state's residential electricity sales in 2024, measured in MWh sold or delivered rather than in customers. The state-wide average realised residential price in 2024, computed from the same EIA file, was 11.52 cents per kWh, so Idaho Power Co's customers paid 0.24 cents above the Idaho average (+2.1%). For context, EIA's latest monthly figure for Idaho is 14.37 cents per kWh (June 2026, Electric Power Monthly); that is a different, more recent measure across all utilities and is not directly comparable with a 2024 annual average.

It also reports 2024 retail sales in Oregon (14,098 residential customers at 11.29 cents). On the grid side it operates in the WECC NERC region, and reported generation, transmission, buying transmission, distribution, and wholesale marketing as its activities. Balancing authority code: IPCO.
