Texas grid sets a new peak as summer heat tests capacity

ERCOT logged an unofficial record 85,967 MW of demand during triple-digit heat, with capacity still comfortably ahead.

The Texas electric grid hit an unofficial peak demand record on a Wednesday afternoon amid triple-digit temperatures. According to ERCOT data, usage reached 85,967 megawatts around noon, edging past the previous record of 85,508 megawatts set in August 2023. Demand was projected to climb further, to about 90,155 megawatts by 3 p.m.

The grid operator said conditions were normal. When demand topped the record at midday, available capacity stood above 109,300 megawatts — a margin ERCOT described as comfortably above demand. So this was a record without a crisis: the system carried the load.

Still, the item is filed as friction because the trajectory is what counts. Each new peak arrives as electrification broadens — more air conditioning, more data centers, more electric vehicles and heat pumps pulling on the same wires. Records that were exceptional a few years ago are now routine summer events, and the gap between demand and capacity is the thing that keeps power both available and affordable. Abundance in energy depends on that headroom staying wide as demand keeps climbing.

The record is unofficial and was not immediately validated by the grid operator, and the figures were reported via the San Antonio Express-News. Worth watching: whether ERCOT's built margin keeps pace with the demand curve through the rest of the season and into future summers.
