ERCOT increasingly meets rising demand with solar, wind, and batteries ›

---

Since 2021, electricity demand within the Texas electricity grid operated by the Electric Reliability Council of Texas (ERCOT) has steadily increased. In the first nine months of 2025, electricity demand in ERCOT, which manages about 90% of the state's load, reached a record high compared with the same period in previous years. Over those same months, ERCOT had the fastest electricity demand growth among U.S. electricity grids between 2024 and 2025. From January through September 2025, demand for electric power in ERCOT increased 5% compared with the same period in 2024 to 372 terawatthours (TWh), 23% more than the same months in 2021. Since 2023, wind and solar generation, especially utility-scale solar, have been the fastest-growing sources of electricity in ERCOT and are increasingly meeting rising demand.
