Hawaii pays the highest electricity prices in the country: 47.18¢ per kWh on average. For a Tesla Model Y that’s about $130 per 1,000 miles at home, $0.130 a mile. A 30-mpg gas car spends roughly $144 on the same miles, so the gap is much smaller than on the mainland.

What’s going on with electricity prices in Hawaii
Hawaii has the most expensive home electricity in the country by a wide margin: 47.18¢ per kWh in August 2026, against a national average of 18.16¢. Prices rose 22.5% over the past year.
Much of Hawaii’s power has historically come from imported oil, which ties bills to world fuel prices. At this rate, a Model Y saves only about $180 a year against a 30-mpg car, even using the national average gas price of $4.33, and a big electric pickup can cost more to charge than a gas car burns.

Home charging vs Tesla Superchargers vs gas in Hawaii
| How you fuel 1,000 miles (Tesla Model Y) | Cost |
|---|---|
| Home, Hawaii average (47.18¢/kWh) | $130 |
| Tesla Supercharger, standard rate ($0.84/kWh) | $232 |

In Hawaii, a standard-rate Supercharger session costs about 1.8 times as much per kWh as charging at home, and more than the gas a 30-mpg car burns over the same miles. Fast charging is for road trips; the savings come from charging at home. With only 3 sites in the sample, treat the Supercharger figure as a rough guide.
How to pay less to charge in Hawaii
Hawaiian Electric serves Oahu, Maui County and Hawaii Island, and the Kauai Island Utility Cooperative serves Kauai. Because so much solar power reaches the grid during the day, Hawaiian Electric’s time-of-use rates make the middle of the day the cheapest time to use power, the opposite of most of the mainland. If you can charge at work or at home around midday, that’s where the savings are.
Hawaiian Electric and KIUC publish their time-of-use hours online. Put the midday price from your plan into the EV charging cost calculator, and read how time-of-use rates work; in Hawaii the cheap hours are the opposite of the mainland.
