Data Source & Methodology

These emission factors are from EPA eGRID2023 Rev2 (released June 2025), the official US government source for grid electricity emission rates. eGRID uses annual net generation and emissions data from all US power plants to calculate subregion-level output emission rates.

For GHG Protocol Scope 2 reporting, use the CO₂e total output emission rate: 903.306 lb/MWh or 0.4097 kg/kWh.

Frequently Asked Questions

What is the SRTV emission factor for Scope 2 reporting?

The SRTV eGRID2023 Scope 2 location-based emission factor is 903.306 lb CO₂e per MWh (0.4097 kg CO₂e per kWh). This is the value to use in GHG Protocol location-based Scope 2 calculations for facilities in the SERC Tennessee Valley subregion.

Which states are in the SRTV subregion?

How do I convert kWh to kg CO₂e for SRTV?

Multiply kWh by 0.4097. Example: 50,000 kWh × 0.4097 = 20485 kg CO₂e (20.48 tonnes).
