Plug-In Solar in South Dakota

Because South Dakota has neither a plug-in solar law nor net metering, the grid power a kit sends earns only avoided cost, while utility interconnection rules apply.

A home with a plug-in solar panel on the porch railing, the kind of kit South Dakota's rules apply to

Connect in South Dakota only after your electric utility's approval, and use an inverter listed to UL 3700, or an inverter with anti-islanding listed to UL 1741.

South Dakota's Rule Right Now

Hooking up: The PUC's rules on small generator interconnection (S.D. Admin. R. 20:10:36) apply to customers of investor-owned utilities; inverter systems using lab-tested equipment, up to 10 kW, fall under Tier 1. Interconnection costs are generally paid by owners. Customers of co-ops and city utilities follow the rules set by their own utility.

Net metering: None available. South Dakota pays no net metered rate for solar; regulated utilities must buy extra power at a minimum rate that is called avoided cost.
