Revenue 708,143.2 thousand dollars. Sales 6,010,292 MWh. Customers 554,211. Cents per kWh = revenue ÷ megawatt-hours × 100. Monthly bill = revenue × 1,000 ÷ customers ÷ 12.
Hold a Idaho Power household to the filing average and the monthly full service bill changed −1.5% between those two EIA years. Holding the 2024 price fixed, the usage change of −1.8% is worth −$1.98 a month. The price change of +0.4%, from 11.74¢ to 11.78¢, is worth $0.38 on 2025 usage.
11.78¢ per kWh is about even with Idaho's 2025 residential average of 11.83¢. July 2026 in the state was 13.73¢, versus 12.28¢ a year earlier (+11.8%). The utility figure is a full year of average revenue. The state figure is one later month. A household that uses more than 904 kWh will not land on $106.48.
554,211 residential customers were on Idaho Power full service in 2025, at 11.78¢ per kWh. That average folds in the customer charge and whatever riders the utility booked as residential revenue. It is not the last block on a tiered tariff.
The 2025 monthly average for this Idaho Power service was 904 kWh, and the Idaho residential average was 933 kWh. A single month can sit far from either figure. Compare kilowatt-hours with the same month last year before you treat the whole increase as a rate hike.
EIA's 2025 dynamic-pricing file shows residential time-of-use activity at Idaho Power, with 1,093 residential customers enrolled in dynamic pricing. The expensive window is in the tariff, not in that enrollment count. Shifting a dishwasher or an EV charger only helps if you are actually on that schedule.
