CPS Energy and the Electric Reliability Council of Texas both experienced new all-time high energy demand records this week as temperatures soared across the state, with San Antonio reaching a searing 108 degrees on Wednesday.
Demand on brutally hot days across the state is driven up by the wider use of A/C systems as Texans crank up the air to keep cool. Combined with Texas’ growing population and an ongoing drought, both the state grid operator and CPS Energy have seen energy demand grow year over year for the past three years.
On Wednesday, the municipally owned utility set a new all-time high energy demand record of 5,858 megawatts between 6 and 7 p.m., surpassing the previous record of 5,703 megawatts set on Aug. 21, 2023. One megawatt is enough to power about 250 homes on a hot Texas day.
