Why the Idaho bill is what it is
A bill is kilowatt-hours multiplied by price, and states reach similar bills by very different routes. Idaho's electricity costs 30% less than the U.S. average, and the typical Idaho home uses 9% more of it, so the bill lands 24% below the national average. Price, not usage, is what drives the Idaho bill.
Compare District of Columbia: households there pay almost the same bill ($113.23 against $108.73) at a rate 1.5 times Idaho's — 17.71¢ against 11.52¢ — because they use 639 kWh a month where Idaho homes use 944.
At today's rate
The 2024 figures are the latest annual numbers EIA has published. Idaho's average residential rate has since moved to 14.37¢/kWh (June 2026). At the same 944 kWh a month, that puts the typical bill near $135.62 — 25% higher. That is an estimate: it holds usage at 2024 levels, and usage swings with the weather.
