Texas halts data center grid connections over power demand

Governor Greg Abbott directed the Public Utility Commission of Texas and the Electric Reliability Council of Texas (ERCOT) to audit all data centers in the interconnection queue. This freeze halts ERCOT's planned "Batch Zero" connection notifications. The state's grid queue currently holds over 1,800 projects representing more than 474 gigawatts of requests—over five times the state's record peak demand—with data centers making up about 90 percent of those requests. ERCOT projects that overall electricity demand could double by 2032.

The rapid expansion has triggered significant financial and environmental concerns. Data center tax breaks now cost Texas over $1 billion annually, with projected sales tax revenue losses reaching $3.2 billion over the next two years. Furthermore, water resources are strained. In 2024, Texas natural gas plants consumed 56 billion gallons of water, coal plants used 34 billion gallons, and nuclear plants used 26 billion gallons to generate power, while data centers directly consumed 8 billion gallons for cooling.

For AI practitioners and developers, this moratorium disrupts deployment timelines and forces a shift in infrastructure strategy. The pause does not affect projects utilizing "behind-the-meter" on-site power generation. Texas currently leads the nation with 40 gigawatts of announced behind-the-meter capacity. Major technology firms, including Meta, Microsoft, Amazon, Oracle, OpenAI, and Anthropic, are increasingly bypassing the grid by deploying on-site natural gas generators, mobile gas generators on semitrucks, and aeroderivative turbines.

The regulatory crackdown comes amid rising political pressure for Abbott, who is leading Democratic challenger Gina Hinojosa by just one percentage point in a recent Fox News poll. Hinojosa has called for an even stricter, total moratorium on data center development. Texas is not alone in its hesitation; New York Governor Kathy Hochul enacted a yearlong data center construction ban on July 14, and Virginia lawmakers are debating similar restrictions.
