Texas's grid operator, ERCOT, made it through the summer of 2026 without issuing a single conservation appeal or emergency alert, a sharp turnaround from 2023, when the same stretch of summer saw six such appeals. Battery storage is getting real credit for the improvement, and the numbers support it.

The real figures: battery discharge hit a peak of 13,256 megawatts on 23 August, with roughly 11,573 megawatts discharging during the critical evening demand ramp, the exact window that used to trigger emergency appeals. At the same point in the 2023 summer, batteries were contributing just over 1,000 megawatts. That's roughly a tenfold increase in three years.

The bottom line: this is a genuinely solid, well-documented improvement, and battery storage is a real part of the story, not marketing spin. Worth remembering next time someone claims grid batteries are all promise and no delivery.
