Power plants in Tennessee emitted 661.2 lb CO2e per MWh generated in 2023 (0.2999 kg/kWh), 14% cleaner than the US average, according to EPA's eGRID2023 state rate. Their generation was 60% carbon-free and 12% 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 Tennessee's ZIP codes are in the SRTV (SERC Tennessee Valley) eGRID subregion, whose Scope 2 factor is 903.306 lb CO2e/MWh (0.4097 kg/kWh).
Generation by power plants in Tennessee, 2023 (EPA eGRID2023 state resource mix).
Using the SRTV subregion factor (903.306 lb CO2e/MWh = 0.4097 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 Tennessee ZIP codes use the SRTV factor: 903.306 lb CO2e/MWh.

For Scope 2 reporting, it depends on the ZIP: all are in SRTV, 903.306 lb CO2e/MWh. EPA's state rate for plants in Tennessee is 661.2 lb CO2e/MWh, 14% cleaner than the US average.
Multiply the facility's annual kWh by the kg/kWh factor of its ZIP code's eGRID subregion (0.4097 for SRTV) 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 Tennessee generated 60% carbon-free and 12% renewable electricity in 2023. At 661 lb CO2e/MWh, the state rate is 14% cleaner than the US average of 770.9 lb/MWh.
