South Dakota Electricity Prices

In April 2026, the average residential electricity price in South Dakota was 14.52¢/kWh. Against a 19.32¢ national average, the state sits 24.8% lower. That is 8.6% higher year over year. For a household near the U.S. average of 10,500 kWh a year, that works out to about $1,525 annually — which is what a solar array would aim to cut.

What we measure: Average residential retail price of electricity published by the EIA for the state, in cents per kilowatt-hour — a statewide monthly average, not a personalized utility tariff or the rate any single household pays. EIA publishes state retail-price data on a lag of roughly two to three months; the latest period shown reflects that lag.
