Regulated: your utility sets the rate
You cannot shop for supply in Hawaii
Hawaii is a regulated market. Your utility is your only option for supply, and the rate is set through a public commission process rather than by competition. Pricing tends to be more stable than in deregulated states, and there is no switching decision to make.
That makes the levers on your side of the meter the only ones available: what you run, for how long, and whether you generate any of it yourself.
What every appliance costs to run in Hawaii
All figures below are computed at the Hawaii rate of 52.00 cents. The last column shows the annual difference against the same appliance at the national average, which is where the effect of living here actually shows up.
At 52.00 cents, Hawaii is one of the states where residential solar economics work most easily. Every kilowatt-hour a rooftop array offsets is worth 52.00 cents rather than the 18.44 cents it would be worth nationally, and payback periods shorten accordingly.
Typical peak sun hours across the West region run around 3 to 6 hours a day as an annual average, though the spread within a region can be wide. For a figure based on your actual location rather than a regional band, use the location-based solar production calculator, and the solar payback calculator for the financial side.
Questions people actually ask
What is the average electricity rate in Hawaii?
52.00 cents per kilowatt-hour for residential customers, which is 182.0 percent above the US average of 18.44 cents.
What is the average electric bill in Hawaii?
About $203 a month. That reflects both the rate and how much electricity households here typically use, which is driven mostly by climate and heating fuel.
Can I choose my electricity provider in Hawaii?
No. Hawaii is a regulated market, so your utility is the only supplier available and the rate is set through the state commission.
Why is my electricity bill higher than the Hawaii average?
The state average blends every household, including small apartments. Electric heating, electric water heating, a pool pump, an older refrigerator or an EV will each push a bill well above it. The appliance table above shows what each of those costs at the Hawaii rate.
Costs on this page use a national average residential rate of 18.44¢ per kWh (August 2026, EIA-derived state residential averages). Your own rate is printed on your electricity bill and is the number that actually matters. Every figure here is recalculated from one central rate setting, so these tables move when the national average moves.
