Why Solar Makes Sense in South Dakota

Customer-Owned Solar Is Allowed

South Dakota homeowners and businesses can generate electricity for their own use and interconnect with regulated utilities, which gives customers a legal path to install on-site solar and reduce grid purchases.

State Tax Treatment Can Improve Project Value

South Dakota provides a local property tax exemption for renewable energy systems under 5 megawatts. That helps protect project economics even though the state does not use a traditional net metering structure.

Rural and Agricultural Properties Can Be a Good Fit

South Dakota’s farms, ranches, shops, and outbuildings often have open space and daytime electric loads that can work well with properly sized solar systems.

Solar Economics Depend on Self-Use and Utility Compensation

Because South Dakota does not use a statewide net metered rate, the best-performing projects are usually those sized around on-site consumption, local utility terms, and realistic production estimates.
