South Dakota Net Metering

Roughly 7.04% of the electric companies in South Dakota offer net metering to their customers. At the state level, South Dakota is known for nonexistent net metering and feed in tariff legislation.

Energy Loss

The state has 56 electricity providers who are reporting energy loss. The average energy loss amount for these providers is 2.93%. For comparison, the US average energy loss is 2.72%. South Dakota has a rank of 36th worst in the country for grid efficiency based on energy loss.

Solar Taxes And Rebates

State governments can help encourage private residents to consider installing private solar panels by promoting tax incentives and rebates to their populace. South Dakota has a tax credit of $1000 or less or no state tax. There are currently no state sponsored rebates available to consumers who are considering installing solar. South Dakota residents have the ability to apply a 100% property tax exemption for the purchase of private solar, which is better than almost all other states. Residents in the state do not have access to a sales tax exemption when purchasing solar.

State Level Initiatives

Policies drawn up at the state level affect whether a state is friendly towards customers searching for renewable energy sources. Many states require renewable fuels to make up a portion of the fuel used for electricity generation by providers in the state. These requirements are known as Renewable Portfolio Standards (RPS). Unfortunately, South Dakota has no requirements in place at this time. Additionally, there are currently no low income solar programs to encourage low income families to install solar panels.
