Solar in South Dakota

Solar Landscape in South Dakota

South Dakota's electricity market is served by a mix of investor-owned utilities, municipal utilities, and rural electric cooperatives. The state's only canonical utility in the precomputed_solar data is the City of Sioux Falls. Major IOUs include Northern States Power (Xcel Energy) serving the eastern part of the state and Black Hills Energy serving the western part including Rapid City.

Without a statewide net metering mandate, each utility sets its own policies for solar interconnection and compensation. Some utilities offer voluntary net metering or solar buyback programs, while others provide minimal or no compensation for exported solar generation. The PUC regulates interconnection practices and pricing for utilities within its jurisdiction.

Permitting

South Dakota does not have statewide solar permitting standards. Permitting is handled at the local city and county level, with significant variation across jurisdictions. Many rural areas in the state may not have specific solar permitting requirements.

No South Dakota jurisdictions have been confirmed as SolarAPP+ participants as of March 2026. Sioux Falls, the state's largest city, has a building permit process for solar installations. Given the state's low solar adoption rate, permitting infrastructure is less developed.

Typical residential solar permitting in South Dakota takes 5-20 business days depending on the jurisdiction. Rural areas may have minimal permitting requirements. Overall installation timelines from contract to permission to operate are generally 4-8 weeks.
