Texas grid officials are warning that electricity demand across the state could reach record levels this summer as extreme heat, rapid population growth and rising industrial power use continue to strain the system.
The Electric Reliability Council of Texas (ERCOT), which manages most of the state’s power grid, projects peak demand could exceed 92,000 megawatts during the hottest months of 2026. That would surpass previous records set in recent summers as air conditioning use and economic growth continue to push consumption higher.
ERCOT officials said the forecast reflects both traditional and emerging drivers of electricity use. While air conditioning remains the largest factor during heat waves, they said continued population growth across Texas and expanding industrial activity are significantly increasing baseline demand.
Data centers tied to artificial intelligence and cloud computing, along with crypto mining operations and large manufacturing facilities, are contributing to round-the-clock electricity consumption that adds pressure to the grid even outside peak afternoon hours.
Grid operators said the most vulnerable period typically occurs in the early evening, when solar energy production declines but residential cooling demand remains high. Wind generation can fluctuate, creating a tighter supply window during peak summer days.
Despite the higher forecast, ERCOT officials said the grid is in stronger condition than in past years due to added generation capacity, including solar power, battery storage and new natural gas facilities. Improvements in forecasting and demand-response programs have also helped stabilize operations during periods of extreme heat.
State energy leaders have repeatedly emphasized that while the grid is expected to be tight at times, they are not currently projecting widespread outages under normal conditions.
Still, officials cautioned that extended heat waves, unexpected power plant outages or sudden spikes in demand could create stress on the system, particularly during late afternoon and evening peaks.
Texas has experienced record-breaking electricity demand in consecutive summers as temperatures continue to rise and the state’s population expands at one of the fastest rates in the country.
