Duke Energy Kentucky
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.
Duke Energy Kentucky is an investor-owned utility that reported 139,405 residential customers in Kentucky on Form EIA-861 for 2024, with a service territory that touches 6 counties.
Its average residential price that year was 13.44¢ per kilowatthour, 5.1% above the Kentucky average of 12.79¢ and 18% 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 $119.52 a month on average use of 889 kWh a month. Across Kentucky the average bill was $133.81 on 1,047 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 130.6 minutes per customer with major event days included and 91.5 minutes with them excluded, calculated under IEEE 1366 standard. The median among Kentucky utilities reporting was 396.4 minutes with major event days; this utility's figure is 67% below that median.
The average price is up 46.1% on 2019, against up 18.4% for Kentucky as a whole, and up 10.6% on 2023. EIA's early release for 2025, which has not been fully edited, shows 13.86¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 139,405 | 1.5 TWh | 37% | $199,940,500 | 13.44¢ |
| Commercial | 14,374 | 1.8 TWh | 44% | $200,525,000 | 11.35¢ |
| Industrial | 294 | 720.3 GWh | 18% | $70,765,300 | 9.82¢ |
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: 4.7 TWh in total, of which 56.1% was its own net generation and 2.1 TWh was bought wholesale; summer peak demand 845 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 0.85 interruptions per customer with major event days, 0.73 without; CAIDI 154.5 minutes per interruption. EIA's Kentucky total across all reporting utilities was 648.3 minutes with major event days and 153.3 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.
