As Texas power demand surges, solar, wind and storage carry the load
Electricity demand is surging in Texas, and solar, wind, and battery storage are meeting it.
According to new data from the US Energy Information Administration (EIA), electricity demand across the Texas grid managed by the Electric Reliability Council of Texas (ERCOT) hit record highs in the first nine months of 2025. ERCOT, which supplies power to about 90% of the state, saw demand jump 5% year-over-year to 372 terawatt hours (TWh) – a 23% increase since 2021. No other major US grid has grown faster over the past year.
