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.

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.
