Overview

Hourly weather-zone actual-load history for ERCOT, including the eight weather zones and a system total. Use it for zonal and historical hourly analysis; for the freshest current system-wide demand, prefer System-Wide Demand (ercot_system_wide_demand) after comparing latest timestamps. Analysts use this archive to study load shape and peaks, normalize demand against temperature, and contextualize price moves and reserve conditions. It comes from ERCOT report NP6-345-CD.
