Powder River Energy Corp
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.
Powder River Energy Corp is an electric cooperative that reported 15,458 residential customers in Wyoming and 1 other state on Form EIA-861 for 2024, with a service territory that touches 7 counties.
Its average residential price that year was 11.73¢ per kilowatthour, 5.9% below the Wyoming average of 12.47¢ and 29% 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 $133.34 a month on average use of 1,137 kWh a month. Across Wyoming the average bill was $107.65 on 863 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 496.5 minutes per customer with major event days included and 295.2 minutes with them excluded, calculated under IEEE 1366 standard. The median among Wyoming utilities reporting was 92.1 minutes with major event days; this utility's figure is 439% above that median.
The average price is up 8.1% on 2019, against up 11.5% for Wyoming as a whole, and down 1.3% on 2023. EIA's early release for 2025, which has not been fully edited, shows 12.20¢.

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 TWh in total, of which 0% was its own net generation and 2 TWh was bought wholesale; summer peak demand 251 MW.

Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 2.88 interruptions per customer with major event days, 2.24 without; CAIDI 172.4 minutes per interruption. EIA's Wyoming total across all reporting utilities was 137.8 minutes with major event days and 109.1 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.
