What businesses in Boise pay
Across Idaho, businesses paid an average 9.62¢ per kWh over the 12 months to August 2026, 30.6% below the U.S. average of 13.87¢, and up 4.7% on the 12 months before. That ranks Idaho 46 of 51, where 1 is the highest price. In 2025 the average commercial account in the state used 4,690 kWh a month, about $436 a month at the state price; that is a mean pulled up by a few very large users, so most small businesses use less.
A city has no price of its own: two businesses on the same street can pay very different amounts per kWh, because the rate schedule, the size of the peak and, where it is allowed, the supply contract matter more than the location. The Idaho page has the state’s price history since 2010 and every utility with at least 500 commercial customers.

Common questions
- Who provides electricity to businesses in Boise?
- EIA lists Idaho Power as electric utilities in Ada County. Which one serves a given address depends on the street; the utility on an existing bill is the definitive answer, and a utility can confirm service for a new site.
- What is the average commercial electricity rate in Boise?
- There is no official figure for a city. EIA publishes prices by state and by utility: Idaho Power averaged 9.09¢ per kWh for its commercial customers in 2025, and Idaho averaged 9.62¢ over the 12 months to August 2026. A business’s own price depends on its rate schedule, its demand and, where it can choose, its supply contract.
- Can a business in Boise choose its electricity supplier?
- Idaho commercial accounts buy supply from their regulated utility. Tariff selection and demand management are the available levers. The state page for Idaho explains how it works and who regulates it.
