ERCOT Prior Day Power Market Dashboard

Around the actual load peak in HE16, weather forecasts showed Houston near 87°F and Corpus Christi near 83°F, supporting coastal cooling demand, while Dallas, Austin, and San Antonio held in the mid- to upper-70s with widespread cloud cover and precipitation that moderated broader ERCOT demand. ERCOT load peaked at 66.6 GW in HE16, about 1.6 GW above forecast, before easing into the evening.

Real-time prices at HB_BUSAVG generally cleared above day-ahead through most of the day, especially HE1-17, as actual wind generation underperformed forecast and actual load exceeded forecast from the afternoon forward. Prices softened versus DA during HE18-23 as the day-ahead market had anticipated tighter evening net-load conditions than ultimately materialized.
