Grid & Capacity Ledger
Public electricity demand, planned generation and large-load applications for AI infrastructure planning.
These datasets describe different stages of the power system. Grid demand includes all end uses; it does not measure AI consumption. Planned supply and load applications are not operating capacity.
Monthly capacity ledger
Planned generating and storage units from preliminary EIA-860M inventory. Compare planned year, state and net summer capacity.
Texas large-load queue
A dated view of the gap between requested load, studies, approvals and energization.
Read the units before comparing
MWh is energy delivered during a period. MW and GW express power or capacity. An application, a planned generator and an energized load are not interchangeable. Storage capacity also depends on discharge duration, which this ledger does not measure.
