Chugach Electric Assn 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, Chugach Electric Assn Inc, an electric cooperative, reported 97,048 residential customers in Alaska, with a service territory that touches 2 counties.
Its average residential price that year was 21.24¢ per kilowatthour, 14% below the Alaska average of 24.82¢ and 29% 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 $107.75 a month on average use of 507 kWh a month. Across Alaska the average bill was $143.54 on 578 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 209.0 minutes per customer with major event days included and 124.6 minutes with them excluded, calculated under IEEE 1366 standard. The median among Alaska utilities reporting was 365.7 minutes with major event days; this utility's figure is 43% below that median.
The average price is little changed on 2019, against up 8.3% for Alaska as a whole, and up 2.9% on 2023. EIA's early release for 2025, which has not been fully edited, shows 23.00¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 97,048 | 590.9 GWh | 31% | $125,486,700 | 21.24¢ |
| Commercial | 16,325 | 1.2 TWh | 66% | $209,672,600 | 16.88¢ |
| Industrial | 5 | 52.8 GWh | 3% | $7,514,700 | 14.24¢ |
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: 2.4 TWh in total, of which 85% was its own net generation and 354.6 GWh was bought wholesale; summer peak demand 284 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 1.99 interruptions per customer with major event days, 1.42 without; CAIDI 105.3 minutes per interruption. EIA's Alaska total across all reporting utilities was 327.1 minutes with major event days and 192.4 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.

Generation at plants it operates, 2025
- Natural gas 93.1% 2.8 TWh
- Hydro 6.9% 210.1 GWh
Net generation of 3.1 TWh at power plants this utility operates, from Form EIA-923. It is not the mix delivered to customers: utilities also buy power wholesale (354.6 GWh in 2024), sell generation to others and may co-own plants that another company operates.
Counties in its service territory
Counties the utility listed on Form EIA-861 for 2024. Listing a county does not mean the utility serves all of it.
