North Dakota had the cheapest residential electricity in the United States in 2025, at an average of 11.82 cents per kilowatt-hour (kWh), just ahead of Idaho at 11.83 cents and Nebraska at 12.05 cents [1][2]. Hawaii was the most expensive at 40.40 cents, followed by California at 31.35 cents and Massachusetts at 30.41 cents [1][3]. The US average was 17.24 cents in 2025, up 4.6% from 2024, and the average home used 882 kWh a month for a bill of $152.08 [1].
Which states have the cheapest electricity?
The ten states with the lowest average residential price in 2025 were North Dakota, Idaho, Nebraska, Louisiana, Arkansas, Montana, Utah, Kentucky, Washington and Oklahoma, all between 11.82 and 13.21 cents per kWh [1]. In all, 34 states were below the US average of 17.24 cents [1].
A low price does not always mean a low bill. Louisiana had the fourth-cheapest price, 12.52 cents, but its homes used the most electricity of any state, 1,225 kWh a month, so the average bill was $153.33, slightly above the US average [1]. The lowest monthly bills were in New Mexico ($95.03), Utah ($99.11) and Colorado ($104.38), where homes used 640, 761 and 665 kWh a month [1].
Which states have the most expensive electricity?
Hawaii's 40.40 cents per kWh was 3.4 times North Dakota's price [1][2][3]. California (31.35 cents), Massachusetts (30.41), Rhode Island (29.48) and Connecticut (29.31) followed, and New England filled four of the six most expensive places [1]. Hawaii also had the highest average bill, $218.37 a month, ahead of Connecticut at $211.33 [1].
The EIA attributes Hawaii's high prices mainly to the petroleum fuels the state imports for power plants [4]. More generally, it lists fuel costs, the cost of power plants, transmission and distribution, weather and state regulation as the main reasons prices differ between places [4].

How much did electricity prices rise in 2025?
The US average residential price rose 4.6%, from 16.48 cents per kWh in 2024 to 17.24 cents in 2025 [1]. Prices rose in 46 states and the District of Columbia and fell in 4 states [1].

In 2025, home electricity averaged 11.82 cents per kWh in North Dakota and 40.40 cents in Hawaii, against a US average of 17.24 cents.
Which big utilities have the cheapest and highest prices?
Within a state, prices differ by utility. The lists below compare large utilities, those with at least 500,000 residential customers in a state in 2025, and only their bundled service, where one company both supplies the power and delivers it, so the prices are comparable. That leaves 52 utility-state pairs [1].

Source: DataPorium Electricity Rates, 2025 residential data by utility; bundled service only, utilities with at least 500,000 residential customers in the state [1]. Customer counts are those of the bundled service.
Two of the highest-priced utilities cut prices in 2025: Pacific Gas & Electric's bundled residential price fell 5.3% and Nevada Power's fell 14.7% [1]. Two in the New York area rose sharply: Public Service Elec & Gas Co by 22.6% and New York State Elec & Gas Corp by 23.3% [1]. Customers of the same company can pay very different prices across states: Duke Energy Carolinas averaged 13.41 cents in North Carolina and 13.47 cents in South Carolina, while PacifiCorp averaged 13.52 cents in Utah and 15.18 cents in Oregon [1].
In Hawaii, none of the utilities reaches 500,000 residential customers. Hawaiian Electric Co Inc, the largest with 276,853, averaged 40.54 cents, and Hawaii Electric Light Co Inc 45.80 cents [1][3].
How we ranked
The data are yearly electricity sales, revenue and customers of each utility from official public data, as shown on DataPorium's electricity rates page, for 2024 and 2025; 2025 is the newest year [1]. The average price is a utility's or state's residential revenue divided by its residential sales over the whole year, in cents per kWh. It includes fixed monthly charges and taxes the utility collects as revenue. It is not a tariff: no customer is billed exactly this rate, and individual bills differ with use and rate plan. The average monthly bill is residential revenue divided by customers and 12 months; the average use is sales per customer per month.
In states with retail choice, one company may deliver the power while another sells it. State averages add the revenue of all sellers and divide it by sales without the delivery-only rows, so each customer is counted once [1]. Utility prices for delivery-only service cover only part of the bill, so the utility lists use bundled service only. Each state's figures and its utilities are on DataPorium state pages such as North Dakota, Hawaii and California, and the national ranking is on the DataPorium electricity rates page [1][2][3][5].
