Overview
ERCOT's public real-time supply and demand dashboard at five-minute resolution. This is the preferred dataset for a current actual-versus-forecast demand comparison: series='realized' reports observed demand_mw, series='intraday_forecast' reports demand_mw forecast for the same target event_time at successive source_time vintages, and series='forward_forecast' reports forecasted_demand_mw farther ahead. It also carries committed and available capacity. Operators, traders, and researchers use it to measure current forecast error, headroom, and how forecasts converge toward realized demand.
