Montana Electricity Prices

Montana's average residential electricity rate stood at 13.90¢/kWh in April 2026. Against a 19.32¢ national average, the state sits 28.1% lower. Prices have risen 12.9% year over year. For a household near the U.S. average of 10,500 kWh a year, that works out to about $1,460 annually — which is what a solar array would aim to cut.

What we measure: Average residential retail price of electricity published by the EIA for the state, in cents per kilowatt-hour — a statewide monthly average, not a personalized utility tariff or the rate any single household pays. EIA publishes state retail-price data on a lag of roughly two to three months; the latest period shown reflects that lag.
