Evergy Kansas South: rates, bills and outages

What Evergy Kansas South homes pay per kWh

Evergy Kansas South sold and delivered electricity to 305,665 residential customers in 2025, 27.2%¹ of all homes on Kansas utility lines. EIA measures their price three ways, each for a different period:

These are averages of everything billed, the monthly customer charge, energy charges, the energy cost adjustment and riders, divided by the kWh used. No single line of the tariff shows them, and a home that uses little electricity pays more per kWh than the average because its fixed charge is spread over fewer kWh. The 12-month figure is the nearest to current bills; the calendar-year figure is the one used for rankings.

On that 2025 basis Evergy Kansas South was the 4th lowest of the 11 Kansas utilities with 10,000 or more residential customers, 0.7% above the Kansas average. Those utilities ranged from 12.01¢ per kWh (Midwest Energy) to 17.84¢ per kWh (FreeState Electric Cooperative). Nationally it ranked 80th lowest of 177 large utilities, against a median of 15.07¢ per kWh, and its average was 18.2% below the national average for investor-owned utilities¹.

February bills and July bills

The calendar-year bill of $124.79¹ hides a wide seasonal range. In EIA's monthly data for the 12 months from September 2025 to August 2026, use per home was lowest in February 2026, at 600 kWh with an average bill of $93.84, and highest in July 2026, at 1,503 kWh with $229.52²: more than twice the electricity. The chart shows the summer plateau lasting into August 2026³, and a much smaller rise in January.

Summer use is higher here than at Evergy Kansas Central, whose July average was 1,332 kWh and $205.70, although the two companies' prices are almost the same. Over the full 12 months the average Evergy Kansas South bill was $136.47 on 889 kWh a month, against $131.94 on 860 kWh² at Kansas Central: the gap between the bills is a gap in use, not in price.

In 2025 the price rose and the bill did not

From 2024 to 2025 the residential average rose 2.0%, from 14.25¢ per kWh to 14.54¢ per kWh. Use per home fell over the same years, from 876 kWh to 858 kWh a month, and the two moves cancelled out: the average bill went from $124.92⁴ to $124.79 (−0.1%¹). EIA's figures record the drop in use, not its cause; weather is the usual suspect in a state with both heating and cooling seasons, but the data do not isolate it.

One rate case, two companies

Evergy Kansas South does not take rate cases to the regulator alone. Evergy Kansas Central, Inc. and Evergy Kansas South, Inc. filed their 2025 rate case together, and in September 2025 the Kansas Corporation Commission approved a unanimous settlement in that docket. The two utilities' averages have stayed close in every period EIA reports:

August 2025 was billed before the settlement was approved, so the year-on-year change for August 2026 includes it; for Kansas as a whole, the residential average rose 5.6%³ on the same month a year earlier. EIA's averages do not separate a base-rate increase from fuel costs or riders, and the 2026 months are preliminary. The guide to rate increases explains how a commission decision reaches a bill.

Evergy Metro, Evergy's third Kansas utility, is not part of that rate case. Its Kansas customers averaged 13.31¢ per kWh over the same 12 months and −0.8%² in August 2026³. The Evergy page compares all of the company's utilities in Kansas and Missouri.

Outage minutes: major event days made the difference

Evergy Kansas South customers averaged 244 minutes without power in 2025 counting every event, more than the Kansas average of 197 minutes, with 1.39 interruptions per customer. Leave out major event days, the days a severe storm or similar event knocks out an unusual share of the system under the IEEE 1366 definition, and the figure falls to 84 minutes, against 97 minutes⁵ for Kansas. Most of the year's outage time therefore came on major event days rather than from everyday interruptions.

Counties served, and no choice of supplier

EIA's 2025 territory records place Evergy Kansas South in 24⁶ counties, from Sedgwick, Butler, Harvey and Reno around Wichita to Cowley and Sumner on the Oklahoma line and Crawford, Cherokee, Labette and Montgomery in the southeast. Electric cooperatives, city utilities or another Evergy company also report customers in every one of those counties, so the utility's own service map, not the city or ZIP code, decides who serves an address.

Kansas has no residential retail choice: EIA counted no residential customers buying from a competitive supplier in 2025. A home in this territory buys its electricity and its delivery from Evergy Kansas South, which belongs to the SPP¹ regional grid.

Industry pays the least per kWh

The utility's 3,079 industrial accounts paid an average of 7.78¢ per kWh in 2025, and its 41,198 commercial accounts 11.26¢ per kWh, against 14.54¢ per kWh for homes. Large users typically take power at higher voltage and spread fixed costs over many more kWh. The average across all customers was 11.15¢ per kWh; the average commercial bill was $725.52 a month and the industrial bill $6,858.20¹.

Smart meters, time-of-use and solar

All residential meters are advanced meters (100.0% in 2025), but 1,807 customers, 0.6% of the total, were enrolled in time-of-use pricing. The current plans and their peak hours are in Evergy's Kansas tariff; the time-of-use guide shows how such a plan changes a bill with a large July peak like this one. Rooftop solar reached 2,981 net-metered residential installations with 23.5 megawatts of capacity, 9.8⁸ per 1,000 customers.

For help with summer or winter bills, Kansas received $38.6 million⁹ in federal Low Income Home Energy Assistance Program funds for fiscal 2026; the Kansas page covers the state's prices and assistance.
