Hawaiian Electric Co Inc
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Annual figures: Form EIA-861 for 2024, final release. Monthly state figures run to July 2026.
In its Form EIA-861 filing for 2024, Hawaiian Electric Co Inc, an investor-owned utility, reported 276,206 residential customers in Hawaii, with a service territory that touches 1 county.
Its average residential price that year was 42.87¢ per kilowatthour, about the same as the Hawaii average of 42.86¢ and 160% above the US average of 16.48¢. The figure is residential revenue divided by residential sales, so it folds in fixed charges, riders and every rate schedule the utility bills under.
That works out to an average residential bill of $194.71 a month on average use of 454 kWh a month. Across Hawaii the average bill was $212.12 on 495 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
For reliability it reported a SAIDI of 234.3 minutes per customer with major event days included and 171.6 minutes with them excluded, calculated under another method. The median among Hawaii utilities reporting was 385.0 minutes with major event days; this utility's figure is 39% below that median.
The average price is up 38.1% on 2019, against up 33.7% for Hawaii as a whole, and little changed on 2023. EIA's early release for 2025, which has not been fully edited, shows 40.54¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 276,206 | 1.5 TWh | 25% | $645,375,500 | 42.87¢ |

Customers, sales and revenue count every service type the utility reported (bundled, energy-only and delivery-only). The price column uses bundled service alone, because part-bill revenue would understate it. Sources of energy: 6.6 TWh in total, of which 59.2% was its own net generation and 2.7 TWh was bought wholesale; summer peak demand 1,052 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under another method. SAIFI: 1.89 interruptions per customer with major event days, 1.66 without; CAIDI 123.8 minutes per interruption. EIA's Hawaii total across all reporting utilities was 320.6 minutes with major event days and 225.6 without. Major event days are storms and similar events that a utility's chosen method sets apart; methods differ, so treat comparisons as approximate. What SAIDI and SAIFI mean.

Net generation of 3.9 TWh at power plants this utility operates, from Form EIA-923. It is not the mix delivered to customers: utilities also buy power wholesale (2.7 TWh in 2024), sell generation to others and may co-own plants that another company operates.
