Evergy Kansas South, Inc
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, Evergy Kansas South, Inc, an investor-owned utility, reported 302,508 residential customers in Kansas, with a service territory that touches 24 counties.
Its average residential price that year was 14.25¢ per kilowatthour, about the same as the Kansas average of 14.15¢ and 14% 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 $124.92 a month on average use of 876 kWh a month. Across Kansas the average bill was $123.90 on 876 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 206.3 minutes per customer with major event days included and 87.1 minutes with them excluded, calculated under IEEE 1366 standard. The median among Kansas utilities reporting was 202.0 minutes with major event days; this utility's figure is about the same as that median.
The average price is up 19.9% on 2019, against up 11.3% for Kansas as a whole, and up 9.5% on 2023. EIA's early release for 2025, which has not been fully edited, shows 14.54¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 302,508 | 3.2 TWh | 33% | $453,478,900 | 14.25¢ |
| Commercial | 40,867 | 3.2 TWh | 32% | $354,433,400 | 11.25¢ |
| Industrial | 3,119 | 3.4 TWh | 35% | $260,844,900 | 7.63¢ |
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: 10.1 TWh in total, of which 79.3% was its own net generation and 2.1 TWh was bought wholesale; summer peak demand 2,688 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 1.40 interruptions per customer with major event days, 0.94 without; CAIDI 147.2 minutes per interruption. EIA's Kansas total across all reporting utilities was 285.6 minutes with major event days and 103.6 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.
