What it sells and charges
Full service (energy and delivery)
| Sector | Customers | Sales (MWh) | Revenue | Average price (cents per kWh) |
|---|---|---|---|---|
| Residential | 79,318 | 428,256 | $196,155,700 | 45.80 |
| Commercial | 11,476 | 372,354 | $160,456,300 | 43.09 |

Its average price is 13% above the state average for residential customers (40.40 cents per kWh in HI).
How we got this
$196,155,700 residential revenue ÷ 428,256,000 kWh residential sales = 45.80 cents per kWh
Average price is revenue divided by sales, for full-service customers only. It averages every rate and every month, so one household's price can differ. State averages count revenue from every kind of service and sales only once, as EIA does.
