Texas may have broken its all-time record for energy demand Monday evening as a historic heat wave continues to drive temperatures above 100 degrees across much of the Lone Star State.
According to data provided by the Electric Reliability Council of Texas (ERCOT), total grid demand hit 80,144 megawatts around 5 p.m. Monday evening. ERCOT listed the Texas grid's all-time peak demand record at 80,038 MW in materials published October 2022. This month, it published a fact sheet listing 80,148 MW as the all-time record.
Monday's possible record-breaking demand comes as ERCOT braces for multiple days of record-setting energy demand this week. ERCOT has also issued a Weather Watch lasting through Friday, urging Texans to monitor grid conditions and make plans to reduce energy use during high demand periods in the afternoons and evenings. ERCOT provides a digital dashboard with real-time updates on grid conditions and changes in Texas' energy market with a wealth of information about the status of the grid. Check out Chron's guide to understanding the essential numbers and key terms the ERCOT dashboard has to offer.
