Overview
- ERCOT told state lawmakers that peak demand could reach about 175,000 megawatts by 2032, driven in large part by roughly 65 gigawatts of new large loads tied to data centers.
- The grid set back-to-back summer records, topping 91,308 megawatts on July 22, and met those peaks without outages because of heavy daytime solar output and nearly 12 gigawatts of battery discharge.
- Officials warn solar and batteries ease daytime stress but may not cover late-evening and overnight demand, so regulators are pushing for more dispatchable, round-the-clock capacity such as natural gas plants.
- ERCOT and the Public Utility Commission paused official long-term forecasts after an April projection of 367,790 megawatts was judged implausible and are rebuilding forecasting methods to better account for very large loads.
- Lawmakers are debating changes to incentives and the $10 billion Texas Energy Fund as analysts warn rapid demand growth could raise consumer bills and require clearer market signals to spur new firm generation.
