ERCOT Peak Load Hits Record 91.1 GW as Texas Heat Strains Grid
Hourly peak load on the Electric Reliability Council of Texas grid hit a record 91.1 gigawatts on July 22, 2026, according to the U.S. Energy Information Administration’s Today in Energy report. The peak, recorded at 6:00 p.m. CT during a heat wave, topped the previous record of 85.5 GW set in August 2023 by 6%. Natural gas supplied 48% of generation during the peak, with solar contributing 32%, per EIA data. The agency notes the record could be broken again this summer if another heat wave hits Texas, and points to a similar trend elsewhere: the Southwest Power Pool set its own demand record of 57.9 GW on July 27.
What It Means for Subcontractors
- Rising peak demand adds pressure to Texas’s large-load interconnection queues, meaning E&I and substation contractors should expect continued backlog work tied to generation and transmission upgrades feeding ERCOT’s grid.
- With natural gas (48%) and solar (32%) covering the July 22 peak, contractors in gas-fired plant maintenance, solar EPC, and balance-of-plant construction are positioned for continued build-out as ERCOT capacity additions race to keep pace with demand.
- Grid operators and utilities facing repeat record-breaking peaks are likely to accelerate procurement for transmission reinforcement projects. Firms with pipefitting, civil, and electrical crews available on short mobilization timelines should stay in contact with ERCOT-area utilities and EPCs now, ahead of the next heat-driven demand spike.
