Salmon River Electric Coop 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.
Salmon River Electric Coop Inc is an electric cooperative that reported 2,383 residential customers in Idaho on Form EIA-861 for 2024, with a service territory that touches 3 counties.
Its average residential price that year was 9.00¢ per kilowatthour, 22% below the Idaho average of 11.52¢ and 45% below 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 $119.32 a month on average use of 1,326 kWh a month. Across Idaho the average bill was $108.73 on 944 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 198.9 minutes per customer with major event days included and 198.9 minutes with them excluded, calculated under IEEE 1366 standard. The median among Idaho utilities reporting was 198.9 minutes with major event days; this utility's figure is about the same as that median.
The average price is little changed on 2019, against up 16.5% for Idaho as a whole, and down 1.0% on 2023. EIA's early release for 2025, which has not been fully edited, shows 9.87¢.

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: 107.4 GWh in total, of which 0% was its own net generation and 107.4 GWh was bought wholesale; summer peak demand 17 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 2.00 interruptions per customer with major event days, 2.00 without; CAIDI 99.2 minutes per interruption. EIA's Idaho total across all reporting utilities was 232.8 minutes with major event days and 174.0 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.
