Central Electric Coop, 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, Central Electric Coop, Inc, an electric cooperative, reported 6,483 residential customers in South Dakota, with a service territory that touches 8 counties.
Its average residential price that year was 13.64¢ per kilowatthour, 6.1% above the South Dakota average of 12.86¢ and 17% 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 $201.08 a month on average use of 1,474 kWh a month. Across South Dakota the average bill was $127.81 on 994 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
EIA's reliability file has no SAIDI or SAIFI entry for it in 2024; smaller respondents and energy-only suppliers are not asked for one.
The average price is up 14.2% on 2019, against up 11.3% for South Dakota as a whole, and up 9.3% on 2023. EIA's early release for 2025, which has not been fully edited, shows 14.67¢.
