Actual use can differ when equipment cycles or changes power. Measure at the wall when precision matters.
A statewide average cannot reproduce your utility rate plan. Check whether your bill includes tiered pricing, time-of-use periods, a longer billing cycle, fuel or delivery adjustments, fixed customer charges, taxes, or credits.
Use your actual all-in price when possible
For a personal estimate, divide the total electric charges on your bill by the total kWh used. That captures the combined price represented on that bill.
total electric charges ÷ total kWh = your all-in $/kWh
Use Hawaii’s statewide average as a benchmark, not a household quote
Hawaii’s statewide residential average can help compare energy costs, but an individual bill depends on the island, utility service area, rate schedule, fixed charges, credits, and the billing period. Use the all-in price from the household’s own statement when evaluating a new load.
Cooling, electric water heating, pool equipment, dehumidification, and EV charging can create long or recurring loads. Modeling each category separately makes it easier to see which change could materially affect the bill.
Match the estimate to the correct island and utility rate schedule.
Separate grid purchases from any rooftop-solar export credits.
Check monthly kWh and billing days before comparing dollar totals.
Model flexible loads at the time-of-use price when the household uses a time-varying plan.

Why can my utility rate differ from the state average?
Utility territory, rate plan, time of use, fuel adjustments, taxes, fixed fees, and the billing period can all change the price a household actually pays.
