Maine Electricity Prices

Maine sits in the most expensive quarter of the country — 28.63¢ per kilowatt-hour in May 2026, 6th-highest of 51 and 47.5% above the national benchmark. The index reports the published average, not its causes.

At Maine's May 2026 average of 28.63¢/kWh, 10,500 kWh of annual use works out to $3,006 a year — around $251 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $968 gap between the two published averages, more for Maine, not a bill either way.

Over the full EIA series the Maine jurisdiction average has risen 121% since January 2001, from 12.96¢ to 28.63¢ in May 2026 — a compound 3.2% per year. Maine is among the most month-to-month variable third of jurisdictions.

February 2026, at 32.17¢ per kilowatt-hour. The May 2026 reading of 28.63¢ sits 11.0% below that peak. The lowest monthly average on record was 10.66¢ in January 2002.

September. Measured over the 25 complete calendar years the EIA series covers for Maine, 2001 through 2025, September runs highest relative to its own year and January runs lowest — a swing of roughly 4.5 percentage points.

Among Maine and its land-border neighbours in May 2026, Vermont posts the lowest average at 24.89¢ and Massachusetts the highest at 28.82¢. Maine ranks 3rd of 4 in the group, at 28.63¢.

Almost certainly not exactly, and this is the one caveat that governs every figure on this page. The published value is the EIA residential average across every utility and residential rate class in Maine for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 26.63¢ in October 2025 and 32.17¢ in February 2026. Your own rate depends on your utility, tariff, usage tier, time-of-use schedule, and fixed monthly charges, none of which this index models. Read your bill for the rate that applies to you.
