Sioux Valley SW Elec Coop electricity rates

It is a smaller system, serving 22,213 residential customers, which means its fixed costs are spread across a narrow base. At 12.94¢ per kilowatt-hour it is one of the cheaper places to buy electricity in South Dakota, 17.7% under the statewide average of 15.73¢.

Consumption here is high, 1,239 kilowatt-hours a month against a national average of 871. Long cooling seasons, large detached homes and electric resistance heating are the usual causes, and together they matter more to the bill than 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 Sioux Valley SW Elec Coop customer went 71 minutes without electricity across 1.01 interruptions. 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.

Sioux Valley SW Elec Coop offers time-of-use pricing and critical peak pricing to residential customers. 608 households were enrolled, about 2.7% of its residential base.

These plans are opt-in almost everywhere. They reward households that can move laundry, dishwashing, water heating or electric vehicle charging out of the late-afternoon peak, and they cost more than the standard rate for households that cannot. How to tell which group you are in.

26 residential customers had net-metered solar in 2024, totalling 0.27 megawatts. That works out to 1.2 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.
