What the numbers mean no fluff, units always

Demand
MW in use now. 1 MW powers roughly 200 homes at once.
Forecast
Day-ahead demand forecast, MW. The operator commits against it.
Forecast error
Demand − forecast, same hour. Small errors are normal. Large positive errors can push prices up.
Interchange
Net power crossing the boundary, MW. + = export. − = import.
Clean power
Wind + solar + hydro share of generation. Nuclear is tracked separately by EIA and excluded here.
Provenance
Where each number came from. Live EIA rows carry src=eia930 and a real timestamp. Demo rows carry src=demo. This page shows which it is serving — always.
