Hawaiian Electric rates and bills on Oahu
Hawaiian Electric's 276,853 residential customers in Hawaii paid an average of 40.54¢ per kWh in 2025, for an average bill of $189.90 a month on 468 kWh.1 Over the last 12 months (Sep 2025–Aug 2026) the average was 44.75¢, and 49.73¢ in August 2026.2
EIA-861 2025 final (released October 7, 2026) and EIA's monthly utility survey through August 2026 (preliminary); next monthly update expected November 24, 2026. Averages are revenue divided by kWh, all charges included: not the rate printed in a tariff.
1 of 5 Hawaii counties served (EIA-861 2025)
Hawaiian Electric's Oahu homes paid an average of 40.54¢ per kWh in 2025, less than in 2024, but the decline did not last: the average over the last 12 months was 44.75¢ per kWh, and in August 20265 it was +27.5%2 on a year earlier. Oahu homes buy little electricity from the grid and many have net-metered rooftop solar, so the average bill, $189.901 in 2025, was below the Hawaii average.
Which Hawaiian Electric this page covers
Hawaiian Electric says it serves the islands of Oahu, Maui, Hawaii, Lanai and Molokai. EIA's utility survey does not report them as one: the utility filed as Hawaiian Electric Company, Inc. reports customers only in Honolulu County3, which is Oahu, while Hawaii Electric Light Co and Maui Electric Co Ltd report the other islands separately. Every figure on this page is for the Oahu utility, which delivered to 276,853 homes in 2025, 61.7%1 of Hawaii's residential customers.
The price per kWh, three ways
EIA publishes three residential averages for Hawaiian Electric, and each answers a different question:
- Calendar 2025 (Form EIA-861, final): 40.54¢ per kWh1, down from 42.87¢ per kWh4 in 2024.
- Last 12 months, September 2025 to August 2026 (Form EIA-861M): 44.75¢ per kWh.
- Latest month, August 20265: 49.73¢ per kWh2.
Months since January 2026 are preliminary. All three are average revenue per kWh: what residential customers paid in total, divided by the kWh they bought. The average blends fixed monthly charges, energy charges and cost adjustments, so it will not match any single line of the tariff, and a home that uses little pays more per kWh than one that uses a lot.
The 2025 average was 128.0% above the national average for investor-owned utilities and 2nd highest of 177 US utilities with 100,000 or more residential customers. Only SDG&E (California) ranked higher, at 45.77¢ per kWh; the median utility in that group averaged 15.07¢ per kWh1.
A drop in 2025, a sharp rise in 2026
Hawaiian Electric's residential average fell 5.4%1 from 2024 to 2025. EIA's monthly sample shows the reversal that followed. The 12-month average to August 2026, 44.75¢ per kWh, was already above both annual figures, and the August 20265 reading of 49.73¢ per kWh was +27.5%2 on the same month of 2025. The chart shows when it happened: the monthly average stayed close to its 2025 level through the first months of 2026 and climbed from the spring. 2026 months are preliminary and can be revised.

EIA's figures record what customers paid, not why. Fuel is the state-level context: petroleum generated 74.9% of Hawaii's electricity in 2025, the highest6 share among the states, and the Hawaiʻi State Energy Office says that reliance on imported oil makes Hawaii susceptible to price shocks in the global oil market. Rate changes go through the Hawaii Public Utilities Commission, which regulates the state's electric utilities; the guide to rate cases explains how a request reaches a bill.
Little use per home keeps the bill below the price ranking
Oahu homes bought 468 kWh a month from Hawaiian Electric in 2025, against 515 kWh across Hawaii and 874 kWh nationally. That is why a price 2nd highest of 177 large utilities turns into an average bill of $189.90: above the US average of $150.68, but below the Hawaii average of $207.897. Use rose slightly from 454 kWh in 2024, and the lower price still brought the bill down from $194.714 (−2.5%1).
The 2026 price rise shows up in the bill. Over the last 12 months (September 2025 to August 2026) the average Oahu bill was $211.66 for 473 kWh2, almost the same use as in 2025.

Use per home changes modestly through the year. In the last 12 months it ranged from 376 kWh in February 2026 to 533 kWh in January 2026, with average bills of $159.17 and $206.012. The bill in the month of highest use was below the 12-month average bill, because the price per kWh climbed later in the period: over this period the price moved Oahu bills more than use did.

Oahu against the other island utilities
Hawaii runs on several independent island grids, the State Energy Office notes, and EIA's 2025 territory records show no Hawaii county with more than one distribution utility. No Hawaii customer can buy from an alternative supplier (0.0% of residential customers did in 2025). Among the 4 Hawaii utilities with 10,000 or more residential customers, Hawaiian Electric's 2025 average was the 2nd lowest, 0.3% above the Hawaii average. Kauai Island Utility Cooperative, the member-owned cooperative, averaged 38.43¢ per kWh, and Hawaii Electric Light Co 45.80¢ per kWh1.

Businesses on Oahu paid less per kWh than homes in 2025: 34.67¢ per kWh for commercial customers and 30.26¢ per kWh for the utility's 475 industrial accounts, against 40.54¢ per kWh for homes. Across all customers the average was 34.19¢ per kWh1.
Rooftop solar on many roofs, time-of-use on few
Hawaiian Electric reported 68,048 net-metered residential solar installations in 2025, 245.8 per 1,000 residential customers, with 370.0 megawatts of capacity. Hawaii as a whole had 232.3 per 1,000, the highest rate among the states, and the US 38.18. Power that panels produce and use on site never passes through the meter as a sale, which lowers the use per home that EIA reports; it also means the average bill mixes solar homes with homes that buy all their power.
Advanced meters made up 96.3% of residential meters in 2025, so the meters needed for time-based billing are in place in most homes. Few homes use it: 11,939 customers, 4.3% of the total, were enrolled in time-of-use pricing, against 11.3%8 of homes nationally. The hours and prices of each schedule are in Hawaiian Electric's tariff; the time-of-use guide shows how such schedules change a bill.
Outages
Oahu customers were without power for 202 minutes on average in 2025, including major events, fewer than the Hawaii average of 282 minutes, and 154 minutes excluding them. They had 1.419 interruptions each on average. The utility reports under another method (not IEEE 1366), so these figures are not strictly comparable with utilities that use the IEEE 1366 standard.
Service area and help with bills
EIA's 2025 service-territory records list Hawaiian Electric as the only distribution utility in Honolulu County3, so every grid-connected home on Oahu is its customer; no other company or supplier is an option. Hawaii received $8,596,05110 in federal LIHEAP funding for fiscal year 2026; the help paying your electric bill guide explains how to apply.

Hawaiian Electric rates: common questions
What is Hawaiian Electric's rate per kWh?
Oahu residential customers paid an average of 44.75¢ per kWh2 over the last 12 months (September 2025 to August 2026, EIA-861M, 2026 months preliminary) and 40.54¢ per kWh1 in calendar 2025. That is total residential revenue divided by kWh sold, so it blends fixed monthly charges, energy charges and cost adjustments into one figure. No single line of Hawaiian Electric's tariff will match it.
Did Hawaiian Electric raise its rates?
The average price paid fell from 42.87¢ per kWh4 in 2024 to 40.54¢ per kWh in 2025 (−5.4%1), then rose in 2026: in August 20265 it was 49.73¢ per kWh, +27.5%2 against the same month a year earlier (preliminary). Rate changes are approved by the Hawaii Public Utilities Commission.
What is the average Hawaiian Electric bill?
$189.90 a month in 2025 for 468 kWh1, down from $194.714 in 2024. Over the last 12 months (September 2025 to August 2026) it averaged $211.66 for 473 kWh2.
What are Hawaiian Electric's time-of-use hours?
The hours and prices of each time-of-use schedule are set in Hawaiian Electric's tariff, published under Rates & Regulations on its website; EIA does not collect them. EIA does count enrollment: 11,939 Oahu residential customers, 4.3% of the total, were on time-of-use8 pricing in 2025.
