Maine Electricity Prices

In April 2026, the average residential electricity price in Maine was 28.42¢/kWh. Rates there are 47.1% higher than the 19.32¢ U.S. average. Prices have risen 1.1% year over year. That rate implies about $2,984 a year for an average 10,500-kWh home — the higher it climbs, the faster solar pays back.

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.
