Power plants in South Dakota emitted 335.6 lb CO2e per MWh generated in 2023 (0.1522 kg/kWh), 56% cleaner than the US average, according to EPA's eGRID2023 state rate. Their generation was 79% carbon-free and 79% renewable. For GHG Protocol Scope 2 location-based reporting, use the eGRID subregion factor of each facility's ZIP (below), not the state rate: power flows across state lines within a subregion.
South Dakota's ZIP codes fall in 2 eGRID subregions. These are the Scope 2 factors; use the ZIP-level API to get the one for each facility.
| Subregion | Name | lb CO2e/MWh | kg/kWh | Carbon-free | Share of SD ZIPs |
|---|---|---|---|---|---|
| MROW | MRO West | 926.552 | 0.4203 | 51.34% | 91% |
| RMPA | WECC Rockies | 1042.539 | 0.4729 | 41.85% | 9% |
Generation by power plants in South Dakota, 2023 (EPA eGRID2023 state resource mix).
Using the MROW subregion factor (926.552 lb CO2e/MWh = 0.4203 kg/kWh), which covers 91% of South Dakota's ZIP codes; for other parts of the state look up the ZIP. Source: EPA eGRID2023.
For GHG Protocol Scope 2 location-based emissions reporting, multiply each facility's electricity consumption by the emission factor for its ZIP code's eGRID subregion. Facilities in different parts of South Dakota are in different subregions - use the API to get the exact factor by ZIP code.

For Scope 2 reporting, it depends on the ZIP: South Dakota's ZIP codes are in MROW (926.552 lb CO2e/MWh, 91% of ZIPs), RMPA (1042.539 lb CO2e/MWh, 9% of ZIPs). EPA's state rate for plants in South Dakota is 335.6 lb CO2e/MWh, 56% cleaner than the US average.
Multiply the facility's annual kWh by the kg/kWh factor of its ZIP code's eGRID subregion to get kg CO2e, and divide by 1,000 for metric tonnes. The emission factors API returns the factor for any ZIP.
Power plants in South Dakota generated 79% carbon-free and 79% renewable electricity in 2023. At 336 lb CO2e/MWh, the state rate is 56% cleaner than the US average of 770.9 lb/MWh.
