Eastern Maine Electric Coop
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.
Eastern Maine Electric Coop is an electric cooperative that reported 10,803 residential customers in Maine on Form EIA-861 for 2024, with a service territory that touches 3 counties.
Its average residential price that year was 17.06¢ per kilowatthour, 30% below the Maine average of 24.29¢ and 3.5% 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 $85.86 a month on average use of 503 kWh a month. Across Maine the average bill was $133.60 on 550 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 1,084.6 minutes per customer with major event days included and 737.2 minutes with them excluded, calculated under IEEE 1366 standard. The median among Maine utilities reporting was 1,206.0 minutes with major event days; this utility's figure is 10% below that median.
The average price is down 1.3% on 2019, against up 35.8% for Maine as a whole, and up 1.7% on 2023. EIA's early release for 2025, which has not been fully edited, shows 19.36¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 10,803 | 65.3 GWh | 64% | $11,130,900 | 17.06¢ |

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: 102.5 GWh in total, of which 0% was its own net generation and 102.5 GWh was bought wholesale; summer peak demand 21 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 8.00 interruptions per customer with major event days, 5.98 without; CAIDI 135.6 minutes per interruption. EIA's Maine total across all reporting utilities was 1,748.6 minutes with major event days and 274.0 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.
