Average residential price, 2024. Dial position: 25% of 1,230 US utilities had this price or lower. Ticks: Kentucky and US averages.

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.

In its Form EIA-861 filing for 2024, Kentucky Utilities Co, an investor-owned utility, reported 473,342 residential customers in Kentucky and 1 other state, with a service territory that touches 83 counties.

Its average residential price that year was 11.97¢ per kilowatthour, 6.4% below the Kentucky average of 12.79¢ and 27% 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 $131.93 a month on average use of 1,102 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 656.3 minutes per customer with major event days included and 86.4 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 66% above that median.

The average price is up 17.0% on 2019, against up 18.4% for Kentucky as a whole, and down 1.1% on 2023. EIA's early release for 2025, which has not been fully edited, shows 12.07¢.

Month by month

Kentucky Utilities Co (KY)Kentucky average

Form EIA-861M monthly sample, bundled residential service in Kentucky. Preliminary until EIA finalises the year. Latest: 12.66¢ in July 2026, average bill $169.50 on 1,338 kWh.

Sales by sector, 2024

Sector	Customers	Sales	Share of sales	Revenue	¢ per kWh, bundled
Residential	473,342	6.3 TWh	34%	$749,372,900	11.97¢

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: 20.7 TWh in total, of which 91.1% was its own net generation and 1.4 TWh was bought wholesale; summer peak demand 3,565 MW.

Reliability

SAIDI, all events656.3 min

SAIDI, without major event days86.4 min

Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 1.34 interruptions per customer with major event days, 0.80 without; CAIDI 490.8 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.
