Electricity Prices Rose in 44 States — but One Saw an Increase More Than 6 Times the National Average

The U.S. Energy Information Administration’s August electricity data, released October 23, carried a headline number that looks manageable. The average American household paid $0.1816 per kilowatt-hour, up from $0.1757 a year earlier, an increase of about 3.4%. Residential rates rose in 44 states and Washington, D.C., and fell in seven states.

Hawaii’s numbers look nothing like that. Its residential rate rose from $0.3853 to $0.4718, a 22.5% jump, or roughly 6.6 times the national pace. The national average tells you little about any one household’s bill. Electricity is priced locally, and in 2026 the gap between states has grown wide enough that a single inflation figure hides it.

Four States Pulled Far Ahead of the Pack

The top three share one problem: fuel. Hawaii makes much of its power by burning imported oil, so its bills track crude prices closely. That exposure became expensive after the war with Iran began and oil prices surged. Hawaiian Electric (NYSE:HE) warned customers that typical residential bills would rise as global oil prices rose. Maine and New Hampshire sit on a New England grid that relies on natural gas for most of its generation, which leaves them more exposed to fuel swings than states with large hydro or nuclear plants.

Same Electricity, $345 Apart

Where a family lives now affects its power bill as much as how much it uses. At Hawaii’s average rate, 1,000 kilowatt-hours costs about $472. In Nevada, at roughly 12.7 cents, the same power runs about $127. That works out to a $345 difference for identical usage. Hawaii households also start from a higher base: the state’s cost-of-living index stands at 109.951, against a national benchmark of 100.

Electricity is adding to pressure that households already feel elsewhere. The Consumer Price Index rose 0.6% in September alone, and regular gasoline still averages $4.27 a gallon.

Virginia Is the Data Center Test Case

Virginia’s increase is the one that draws the artificial intelligence story. The state hosts the country’s densest cluster of data centers, and a Colorado legislative staff report references the Grid Strategies 2025 load growth report in calling data centers the largest driver of U.S. electricity demand. That demand is also why the nuclear restart keeps coming up in utility conversations (we picked five ways to play it, utilities and fuel included, in a free report here). The rate data alone stops short of proving the AI link. Showing it requires evidence tying new data center load to specific utility investments and to rates that regulators actually approved. The same report notes that states are increasingly exploring more public and standardized large-load tariffs so that big users carry their own grid costs.

Signals That Matter Before Winter Bills Arrive

For utility investors, regulated utilities earn returns on the capital they spend, so rising demand and grid upgrades can lift earnings. Rising bills create the backlash that limits those returns. That backlash is already visible: New York officials this week highlighted state policies driving up utility bills.

Three signals will matter most. First, whether Hawaii’s gap narrows in the next EIA releases now that gasoline is down 4.7% over the past month, a sign that oil costs are falling. Second, whether New England’s winter gas demand drives Maine and New Hampshire higher still. Third, whether Virginia regulators adopt large-load tariffs that move grid costs off residential customers. Each of those will show whether the burden on households stays concentrated in a few states or spreads.
