eGRID2023 Revision 2

2,023

50 U.S. states and the District of Columbia

State output rates describe generation located in a state; they are not consumption-based electricity footprints.
The values are annual averages, not hourly or marginal emissions rates.
No facility load, utility tariff, power-purchase agreement, or data-center operating profile is joined.
Resource-mix shares can differ from electricity delivered to a particular customer because power crosses state borders.
