Power plants in South Carolina emitted 560.4 lb CO2e per MWh generated in 2023 (0.2542 kg/kWh), 27% cleaner than the US average, according to EPA's eGRID2023 state rate. Their generation was 61% carbon-free and 6% 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.
All of South Carolina's ZIP codes are in the SRVC (SERC Virginia/Carolina) eGRID subregion, whose Scope 2 factor is 596.326 lb CO2e/MWh (0.2705 kg/kWh).
Generation by power plants in South Carolina, 2023 (EPA eGRID2023 state resource mix).
Using the SRVC subregion factor (596.326 lb CO2e/MWh = 0.2705 kg/kWh). 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. All South Carolina ZIP codes use the SRVC factor: 596.326 lb CO2e/MWh.

For Scope 2 reporting, it depends on the ZIP: all are in SRVC, 596.326 lb CO2e/MWh. EPA's state rate for plants in South Carolina is 560.4 lb CO2e/MWh, 27% cleaner than the US average.
Multiply the facility's annual kWh by the kg/kWh factor of its ZIP code's eGRID subregion (0.2705 for SRVC) 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 Carolina generated 61% carbon-free and 6% renewable electricity in 2023. At 560 lb CO2e/MWh, the state rate is 27% cleaner than the US average of 770.9 lb/MWh.
