Power Plant Fuel Types, Emissions & Pollution Factors

South Dakota citizens average 1,924.21 kilograms of CO2 emissions per resident from electricity consumption. Total emissions from electricity consumption in the state is 1,750,696,778.74 kilograms, which is the 51st worst total amount of emissions for all states. The state has the 41st most electricity producing plants of any state in the US, with 24 total plants. This translates to the 5th most power plants per citizen in the country. The state of South Dakota's primary fuel source is Wind, with 59.60% of electricity generation coming from this fuel. Conventional Hydroelectric (20.96%) is also used for electricity production, as well as Natural Gas (9.15%).

South Dakota Net Metering

There are 68 companies in South Dakota providing electricity. Of those 68, 13 of them offer some type of net metering option for their consumers, making solar panels and alternative electric sources more economically feasible. At the state level, South Dakota has nonexistent laws for consumers interested in installing solar.

Energy Loss

The state has 13 electricity providers who report energy loss. The average energy loss amount for these providers is 1.81%. With a nationwide average of 2.43%, South Dakota is ranked as the 10th best state in the nation.

Solar Taxes And Rebates

States that want to support solar panel installs at private residences can do so by passing tax incentives and rebates for solar purchase. South Dakota has a tax credit of $1000 or less or no state tax. Offering no rebates for solar panel installs, the state currently is letting down its citizens who want to install private solar panels. South Dakota citizens have the ability to apply a 100% property tax exemption for the purchase of private solar panels, which is as good as it gets. Citizens in the state do not have access to a sales tax exemption when installing private solar.

State Level Initiatives

Statewide legislation has a huge part in determining whether customers who are seeking renewable energy sources can easily find alternatives. States that have Renewable Portfolio Standards (RPS) have requirements in place for all electric suppliers who operate in the state. These standards require that a percentage of electricity must be produced using renewable fuel sources. The state of South Dakota, unfortunately, has no standards in place. Furthermore, the state does not have any sort of low income solar programs that help with the installation of solar panels at low income households.
