Maine electricity bills in context
The average monthly electricity bill in Maine is $156, ranking 26th among the 50 states and DC. This falls slightly below the national average of $158, though the state pays substantially more per kilowatt-hour: 29.62¢/kWh against the national average of 18.07¢/kWh. Maine homes use less electricity than average — 527 kWh per month compared with 876 kWh nationally — and this lower consumption pulls the overall bill down despite the high rate.
Over the twelve-month period from September 2025 through August 2026, the average bill rose 7.9% from the prior year's $145. Looking further back, the bill has grown 64.6% since August 2021 and 84.4% since December 2008. Seasonal variation is marked: February 2026 saw the highest bill at $204, while October 2025 recorded the lowest at $125, a swing of $79 around the twelve-month average.
Among neighbouring states with reported data, New Hampshire's average monthly bill is $173, higher than Maine's $156.

How this is calculated
EIA’s retail-sales dataset reports, for every state and month, total residential revenue and the number of residential customers served. The average monthly bill is simply the first divided by the second — total spending across all households, spread evenly over all accounts.
bill = revenue ÷ customers · averaged over 12 months (September 2025 – August 2026)
Two caveats worth knowing. It is an average, so it blends apartments with large houses — a typical household in Maine may pay well above or below $156. And it counts what was actually billed for electricity, including fixed service charges, so it is not the same as multiplying your own usage by the advertised rate.
