Public Service Co of Oklahoma
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.
Public Service Co of Oklahoma is an investor-owned utility that reported 501,093 residential customers in Oklahoma on Form EIA-861 for 2024, with a service territory that touches 46 counties.
Its average residential price that year was 12.73¢ per kilowatthour, 4.0% above the Oklahoma average of 12.24¢ and 23% 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 $133.19 a month on average use of 1,047 kWh a month. Across Oklahoma the average bill was $132.05 on 1,079 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 188.5 minutes per customer with major event days included and 116.7 minutes with them excluded, calculated under IEEE 1366 standard. The median among Oklahoma utilities reporting was 285.9 minutes with major event days; this utility's figure is 34% below that median.
The average price is up 25.5% on 2019, against up 19.9% for Oklahoma as a whole, and down 8.0% on 2023. EIA's early release for 2025, which has not been fully edited, shows 14.23¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 501,093 | 6.3 TWh | 33% | $800,878,200 | 12.73¢ |
| Commercial | 67,741 | 7 TWh | 36% | $610,771,900 | 8.79¢ |
| Industrial | 5,925 | 5.9 TWh | 31% | $349,700,700 | 5.95¢ |
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: 20.5 TWh in total, of which 48.2% was its own net generation and 10.6 TWh was bought wholesale; summer peak demand 4,198 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 1.55 interruptions per customer with major event days, 1.31 without; CAIDI 121.7 minutes per interruption. EIA's Oklahoma total across all reporting utilities was 270.9 minutes with major event days and 119.6 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 13.1 TWh at power plants this utility operates, from Form EIA-923. It is not the mix delivered to customers: utilities also buy power wholesale (10.6 TWh in 2024), sell generation to others and may co-own plants that another company operates.
