Southeastern Electric Coop Inc electricity rates

It is a smaller system, serving 20,160 residential customers, which means its fixed costs are spread across a narrow base. At 12.41¢ per kilowatt-hour it is one of the cheaper places to buy electricity in South Dakota, 21.1% under the statewide average of 15.73¢.

Its customers use more electricity than the national norm, 1,128 kilowatt-hours a month against 871, which amplifies whatever the rate does.

Owned by the customers it serves, with directors elected by members. Co-ops are frequently outside state rate regulation. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

In 2024 the average Southeastern Electric Coop Inc customer went 71 minutes without electricity . The median across the 941 utilities that report this is 185 minutes.

That is markedly better than typical. Short outage durations usually mean an underground or heavily automated network, and they are expensive to achieve, which is part of why reliable systems often carry higher delivery charges.

14 residential customers had net-metered solar in 2024, totalling 0.12 megawatts. That works out to 0.7 installations per thousand customers, against a median of 8 across the utilities reporting it.

Adoption is below the national median. A low retail rate reduces what solar displaces, and export compensation set at avoided cost rather than the retail rate reduces it further. What exports are actually worth.
