Monongahela Power Co
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.
Monongahela Power Co serves 334,588 residential customers in West Virginia as an investor-owned utility, according to its 2024 Form EIA-861 filing, with a service territory that touches 34 counties.
Its average residential price that year was 13.97¢ per kilowatthour, 7.3% below the West Virginia average of 15.07¢ and 15% 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 $124.56 a month on average use of 892 kWh a month. Across West Virginia the average bill was $154.76 on 1,027 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 851.8 minutes per customer with major event days included and 461.6 minutes with them excluded, calculated under IEEE 1366 standard. The median among West Virginia utilities reporting was 756.5 minutes with major event days; this utility's figure is 13% above that median.
The average price is up 27.1% on 2019, against up 34.0% for West Virginia as a whole, and up 10.7% on 2023. EIA's early release for 2025, which has not been fully edited, shows 14.31¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 334,588 | 3.6 TWh | 29% | $500,111,500 | 13.97¢ |
| Commercial | 56,139 | 3.3 TWh | 26% | $357,066,000 | 10.92¢ |
| Industrial | 6,468 | 5.6 TWh | 45% | $428,976,700 | 7.71¢ |
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: 14.8 TWh in total, of which 71.3% was its own net generation and 4.2 TWh was bought wholesale; summer peak demand 2,151 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 2.87 interruptions per customer with major event days, 2.34 without; CAIDI 297.2 minutes per interruption. EIA's West Virginia total across all reporting utilities was 1,165.5 minutes with major event days and 486.1 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.

Net generation of 16.9 TWh at power plants this utility operates, from Form EIA-923. It is not the mix delivered to customers: utilities also buy power wholesale (4.2 TWh in 2024), sell generation to others and may co-own plants that another company operates.
