Residential Electricity Prices by State 2025

What this chart shows. The average price households paid for electricity in each state and the District of Columbia in 2025, in cents per kilowatt-hour. Hawaii was the most expensive at 40.59 cents, followed by California at 32.54 and Massachusetts at 30.48; North Dakota was the cheapest at 11.81 cents. The national average was 17.30 cents.

How the data is collected. The figures come from the US Energy Information Administration's Electric Power Monthly, which collects monthly sales and revenue from utilities and other electricity sellers on Form EIA-861M. The average price is residential revenue divided by the electricity sold to homes, so it includes delivery charges and fees, not only the cost of generation.

Background. All six New England states are in the top ten, and 17 of the 51 were above the national average. Hawaii makes most of its power from oil: petroleum supplied 74.5 per cent of its utility-scale generation in 2025, according to the same EIA report. At 40.59 cents, a household there paid about 3.4 times as much per kilowatt-hour as one in North Dakota.

Limits. These are averages across all utilities and plans in a state, so an individual bill can differ a lot. The 2025 numbers are preliminary and EIA revises them when it publishes its annual data.
