What a monthly bill looks like
The table shows what different amounts of electricity cost at the latest Hawaii price. Fixed monthly charges are already included in the average price, so a real bill for a small user is usually a little higher than shown and a large user's a little lower.
| Monthly use | Roughly | In Hawaii | At the U.S. average |
|---|---|---|---|
| 495 kWh | The average home in Hawaii (2024) | $237.60 | $90.63 |
| 863 kWh | The average U.S. home (2024) | $414.24 | $158.02 |
| 1,500 kWh | A large or all-electric home | $720.00 | $274.65 |
| 2,000 kWh | An all-electric home in its peak month | $960.00 | $366.20 |
Where the electricity in Hawaii comes from
The largest source of the electricity generated in Hawaii in 2024 was petroleum (oil), according to the Energy Information Administration's state profile. Burning imported oil is the most expensive way to generate electricity at scale, and it ties the price of every kWh to the world oil market. It is the main reason bills here are the highest in the nation.
Power plants here generated 9.2 million MWh in 2024, close to the 9.0 million MWh sold to customers in the state.
How the climate shapes bills
The weather is warm all year, so homes need almost no heating, and many are cooled by trade winds and fans rather than central air conditioning. That keeps the number of kWh used per home among the lowest in the country.
That is why the same price per kWh can produce very different bills in two homes: the price tells you what each kWh costs, and the weather and your heating and cooling equipment decide how many you use. To see the effect of one appliance, compare a window air conditioner, a space heater and a heat pump in the table above.
Can you choose your electricity supplier?
Generally, no. Hawaii does not have a statewide retail choice program for households, so most buy their electricity from the utility or cooperative that serves their address, at prices approved by regulators or set by the local public power provider. Prices still differ between utilities, and between rate plans at the same utility, so check the price per kWh on your own bill and type it into the calculator.
