Tennessee's EPA eGRID2023 electricity emission factor is 903.3 lb CO2e per MWh (0.4097 kg per kWh). This is 17% dirtier than the US national average.
Multiply the facility's annual kWh consumption by 0.4097 to get kg CO2e. Divide by 1,000 for metric tonnes. For facilities spanning multiple Tennessee subregions, use the emission factors API to get the exact factor by ZIP code.
Tennessee's grid is 42% carbon-free and 9% renewable. At 903 lb CO2e/MWh, it is 17% dirtier than the US average of 770.9 lb/MWh.
