Regulated: your utility sets the rate
You cannot shop for supply in South Dakota
South Dakota is a regulated market. Your utility is your only option for supply, and the rate is set through a public commission process rather than by competition. Pricing tends to be more stable than in deregulated states, and there is no switching decision to make.
That makes the levers on your side of the meter the only ones available: what you run, for how long, and whether you generate any of it yourself.
What every appliance costs to run in South Dakota
All figures below are computed at the South Dakota rate of 15.73 cents. The last column shows the annual difference against the same appliance at the national average, which is where the effect of living here actually shows up.
At 15.73 cents, South Dakota sits close enough to the national average that solar payback here tends to track the national picture. The variables that decide it are local: net metering terms, state incentives, roof orientation and shading.
Typical peak sun hours across the Midwest region run around 3.5 to 4.5 hours a day as an annual average, though the spread within a region can be wide. For a figure based on your actual location rather than a regional band, use the location-based solar production calculator, and the solar payback calculator for the financial side.
