How electricity prices work in Idaho
- Your address decides your utility. The tariff of that utility gives the price of each kWh and the monthly charges.
- Tiers. Idaho Power charges a different price for the kWh above a limit, so a month with more kWh has a different average price.
- Not in the calculations. Sales tax, city fees and discount programs are not in the tables on this page. The calculator of each utility shows them where the tariff gives them.
