Hawaii electricity rates and bills

Price per kWh against the other states

Hawaii ranked the highest among the 50 states and DC on the residential price over the last 12 months (September 2025 to August 2026), at 44.27¢ per kWh. That is 26.23¢ per kWh more than the US average. The next state, California, averaged 32.34¢ per kWh over the same 12 months, and Massachusetts 30.39¢ per kWh¹.

All figures here are average revenue per kWh: what customers paid in total, including fixed charges and fuel adjustments, divided by the kilowatt-hours they used. They are not the price printed on a tariff.

Businesses pay the most in the country too. Over the same 12 months, commercial customers paid 40.31¢ per kWh (190.6% above the US average) and industrial customers 35.63¢ per kWh (299.9% above the US average¹).

Most of the power still comes from imported oil

Petroleum generated 74.9% of Hawaii's electricity in 2025, the highest share of any state; across the US the share was 0.4%. Natural gas, the largest source nationally at 40.9%, generated 0.0% in Hawaii, and there is no nuclear plant. Coal produced 13.2% of the state's power in 2015 and none in 2025: according to the Hawaiʻi State Energy Office, coal has not been used for electricity generation since September 1, 2022, when the power purchase agreement for the state's last coal-fired plant expired. Oil's share was 5.5 percentage points³ higher than in 2015.

Solar rose from 0.5% of generation in 2015 to 10.2% in 2025, and wind supplied 6.2%. Renewables together reached 21.7%, against 24.1%³ nationally. The state's stated goal, as the State Energy Office describes it, is 100 percent clean energy.

Most of Hawaii's oil is imported from foreign countries, the State Energy Office notes. Its grid overview says this reliance on imported oil makes Hawaii susceptible to price shocks in the global oil market, and that the state operates on several independent grids rather than one connected system.

A price that falls as well as rises

Hawaii's residential price was 16.34¢ per kWh⁴ in 2001 and 40.40¢ per kWh in 2025, a rise of 147.2%, against 100.8% for the US. The path was uneven. The annual average rose in 15 of the years since 2002, compared with 21 for the country, and it fell as recently as 2025: from 2024 to 2025 it dropped 5.7%, from 42.86¢ per kWh to 40.40¢ per kWh, the 2nd lowest⁵ change among the states.

That decline has since reversed. Over the 12 months to August 2026, the residential average ran 8.8% above the previous 12 months. In August 2026 it was 47.18¢ per kWh, against 38.53¢ per kWh in August 2025; over January to August 2026 it averaged 46.41¢ per kWh, +14.7%¹ on the same months of 2025. Monthly figures for 2026 are preliminary.

Single months move a lot. Within the last 12 months, the monthly residential average ranged from 39.53¢ per kWh in September 2025 to 52.72¢ per kWh in June 2026¹, which is why this page ranks Hawaii on 12-month averages rather than on any one month.

Small use, the largest bill

Hawaii homes use little electricity. The average residential customer used 515 kWh a month in 2025, the 2nd lowest among the states after California, against 874 kWh² nationally. Use changes modestly across the year: over the last 12 months it ranged from 422 kWh in February 2026 to 570 kWh in August 2026, a ratio of 1.4 times¹. In EIA's 2020 household survey, air conditioning accounted for 20%⁶ of Hawaii home electricity use.

The price outweighs the low use. The average monthly bill was $207.89 in 2025, the highest in the country and $57.21 more a month than the US average. It was 2.0%² lower than in 2024, when the price was higher. Over the last 12 months the computed average was $227.70, and in August 2026 alone it reached $269.05 for 570 kWh¹ (preliminary).

Households' own reports come in lower than EIA's average but still above the national figure. In the Census Bureau's 2025 American Community Survey, Hawaii households that pay for electricity put their median monthly bill at about $177, against $169 nationally, and 32.5% said they paid $250 or more (±1.2 percentage points), the 5th highest⁷ share among the states. These are recalled bills and survey estimates.

Four island utilities, no retail choice

Hawaiian Electric delivers power to 61.7% of the state's residential customers, all in Honolulu County. Hawaii Electric Light Co serves 17.7%, Maui Electric Co Ltd 13.8% and Kauai Island Utility Cooperative, a member-owned cooperative, 6.8%⁸. EIA's 2025 territory records list 0⁹ counties with more than one distribution utility, so the address alone decides the company.

In 2025, average residential prices among the four ran from 38.43¢ per kWh at Kauai Island Utility Cooperative to 45.80¢ per kWh at Hawaii Electric Light Co, a spread of 7.37¢ per kWh. The three investor-owned utilities averaged 41.72¢ per kWh together and the cooperative 38.43¢ per kWh. Hawaiian Electric customers paid 40.54¢ per kWh, 2nd highest of 177 large US utilities (100,000 or more residential customers), on 468 kWh⁸ a month. Use per home differs from island to island, so the utilities can rank differently on bills than on prices.

Hawaii has no competitive retail market: 0.0% of residential customers bought from an alternative supplier in 2025, and EIA records 0⁸ such suppliers. The Hawaii Public Utilities Commission regulates the public utility companies that provide electricity in the state.

Rooftop solar and smart meters

Hawaii had 232.3 net-metered residential solar installations per 1,000 residential customers in 2025, the highest figure among the states; the US figure was 38.1. That is 104,259 installations, 68,048¹¹ of them on Hawaiian Electric's grid. Net-metered homes buy fewer kilowatt-hours from their utility, which lowers the average use per customer that EIA reports.

Advanced meters were installed for 96.1% of residential customers in 2025. Time-of-use and other time-varying rates remain a small share: 4.3%¹¹ of residential customers were enrolled.

Outages and help with bills

Hawaii customers averaged 282 minutes without power in 2025 including major events, 19th highest among the states, and 188 minutes excluding them, the 7th highest. They had 2.02 interruptions each on average, 7th highest¹². Hawaiian Electric reports with a method other than the IEEE 1366 standard, so its figures are not strictly comparable with other utilities'.

Federal Low Income Home Energy Assistance Program (LIHEAP) funding for Hawaii was $8,596,051 for fiscal 2026, and the first release for fiscal 2027 was $7,784,253. Per occupied home that is $17.16, the 4th lowest¹³ among the states. The help paying your electric bill guide explains how to apply.
