Over six weeks since late July, the Electric Reliability Council of Texas’ weekly average peak loads all exceeded a record set in 2023, the Energy Information Administration said.

“Sustained high temperatures have contributed to persistently high electricity demand in [ERCOT],” EIA said. “The past six weeks, from the week ending July 25 through the week ending August 29, have all exceeded the 2023 record.”

EIA said the hourly average for the week ending Aug. 22 “was 10% greater than the highest hourly average for any week in summer of 2025 and 6% greater than the previous record of 70 GW set in 2023.”

ERCOT’s long-term load forecast projects continually increasing peak loads, which reach 154 GW by 2035, though a recent report from Ascend Analytics forecast a peak load of 120 GW in 2030.
