Overview

It comes from ERCOT's official Actual System Load by Weather Zone and system-wide reporting (report NP6-235-CD) and reflects settled demand rather than the faster, provisional real-time readings. Operators, traders, and researchers use it to study how Texas load rises and falls through the day and across seasons, to benchmark forecasts against what the grid actually consumed, and to anchor analyses of peak demand and stress events.

Query contract
Preserve one canonical row per (event_time) before aggregating.
Analysis rules
Group only after preserving the declared grain: event_time.
Interpretation
This is settled 15-minute demand posted hourly. For current operational or price-causation work, use series='realized' from ercot.supply_demand instead.Do not align this interval-ending settlement series to the instantaneous supply_demand feed without first aggregating both to a compatible interval.
