New Hampshire Electricity Prices

New Hampshire sits in the most expensive quarter of the country — 27.33¢ per kilowatt-hour in May 2026, 9th-highest of 51 and 40.8% above the national benchmark. The index reports the published average, not its causes.

At New Hampshire's May 2026 average of 27.33¢/kWh, 10,500 kWh of annual use works out to $2,870 a year — around $239 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $832 gap between the two published averages, more for New Hampshire, not a bill either way.

Over the full EIA series the New Hampshire jurisdiction average has risen 102% since January 2001, from 13.52¢ to 27.33¢ in May 2026 — a compound 2.8% per year. Month-to-month movement has been about typical for a reporting jurisdiction.

September 2022, at 32.26¢ per kilowatt-hour. The May 2026 reading of 27.33¢ sits 15.3% below that peak. The lowest monthly average on record was 11.26¢ in September 2001.

October. Measured over the 25 complete calendar years the EIA series covers for New Hampshire, 2001 through 2025, October runs highest relative to its own year and July runs lowest — a swing of roughly 5.5 percentage points.

Among New Hampshire and its land-border neighbours in May 2026, Vermont posts the lowest average at 24.89¢ and Massachusetts the highest at 28.82¢. New Hampshire ranks 2nd of 4 in the group, at 27.33¢.

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 New Hampshire for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 22.79¢ in July 2025 and 27.82¢ in September 2025. 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.
