What Maine's Electricity Data Tells Us
24.29¢/kWh is what a typical residential customer in Maine pays for electricity in 2024, reaching 742.5K metered households, landing 47.4% above the national residential average, 16.48¢/kWh. Commercial customers pay 18.22¢/kWh while industrial buyers pay 12.46¢/kWh, reflecting the cost differentials that come from voltage level, load factor, and contract length across EIA Form-861 survey respondents. Yearly residential electricity sales reached 4.9M MWh, generating about $1.2B in utility revenue, a useful yardstick for sizing local demand against the grid mix that serves it.
natural gas dominates Maine's generation mix, supplying 45.4% of in-state production, with a secondary role played by hydro at 20.3%, while wind adds another 17.4%. Maine draws 51.9% of its electricity from renewable sources, solar, wind, hydro, geothermal, and biomass together, a figure that matters because each renewable megawatt-hour displaces fuel costs that otherwise flow through to retail bills. A portfolio this clean typically carries lower marginal generation costs once capacity is built, though transmission upgrades can offset part of the saving.
Looking back across EIA records, residential prices in Maine moved from 15.83¢/kWh in 2016 to 24.29¢/kWh in 2024, a 53.4% shift over that window. States charging a similar rate include New York, Alaska, New Hampshire, a useful peer set for a sanity check. For anyone negotiating a supplier contract, weighing an energy-efficiency upgrade, or modeling a household budget, the combination of current rate, multi-year trend, and generation mix offers a sturdier footing than any single data point on its own.
