New Hampshire Electricity Emission Factor 2023

EPA eGRID2023 Rev2 · NEWE subregion

Power plants in New Hampshire emitted 276.2 lb CO2e per MWh generated in 2023 (0.1253 kg/kWh), 64% cleaner than the US average, according to EPA's eGRID2023 state rate. Their generation was 73% carbon-free and 17% 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.
