Power plants in Ohio emitted 1068.3 lb CO2e per MWh generated in 2023 (0.4846 kg/kWh), 39% dirtier than the US average, according to EPA's eGRID2023 state rate. Their generation was 16% carbon-free and 4% 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 Ohio's ZIP codes are in the RFCW (RFC West) eGRID subregion, whose Scope 2 factor is 916.054 lb CO2e/MWh (0.4155 kg/kWh).
Generation by power plants in Ohio, 2023 (EPA eGRID2023 state resource mix).
Using the RFCW subregion factor (916.054 lb CO2e/MWh = 0.4155 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 Ohio ZIP codes use the RFCW factor: 916.054 lb CO2e/MWh.

For Scope 2 reporting, it depends on the ZIP: all are in RFCW, 916.054 lb CO2e/MWh. EPA's state rate for plants in Ohio is 1068.3 lb CO2e/MWh, 39% dirtier than the US average.
Multiply the facility's annual kWh by the kg/kWh factor of its ZIP code's eGRID subregion (0.4155 for RFCW) 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 Ohio generated 16% carbon-free and 4% renewable electricity in 2023. At 1068 lb CO2e/MWh, the state rate is 39% dirtier than the US average of 770.9 lb/MWh.
