Maine electricity bills in context

Maine's average monthly electricity bill is $155, placing it 26th among the 50 states and DC, counting down from the most expensive. This precisely matches the national average, though the state reaches it through different arithmetic: homes here pay 28.89¢/kWh, well above the national rate of 17.84¢/kWh, but use only 537 kWh per month against the national average of 871 kWh. The higher price per unit pulls the bill up; the lower consumption pulls it down, leaving them nearly balanced.

Over the past year, since June 2025, Maine's bill has risen 10.2%, from $141 to $155. The longer view shows steeper growth: the bill has grown 61.4% since May 2021 and 83.3% since December 2008. Seasonal variation is pronounced, with February 2026 reaching $204 while June 2025 fell to $123, a swing of $81 around the twelve-month average.

Across the border in New Hampshire, the average bill stands at $167, notably higher than Maine's. This places Maine's electricity costs below those of its neighbour to the south.

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 (June 2025 – May 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 $155. 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.
