Texas's grid operator, ERCOT, can't absorb AI's power demand alone — so data center developers are building their own gas plants to skip the queue. The permit count suggests the workaround is scaling faster than the grid can follow.
Texas's electric grid operator is facing an unprecedented planning challenge as AI data centers seek to plug in. The workaround, documented across permit filings, is on-site fossil fuel generation: developers are building their own gas plants to bypass ERCOT's transmission and interconnection queue constraints.
The scale of that workaround is now quantified. Texas hosts 32 of the 74 large new natural-gas power plants proposed nationwide for data centers — more than 40 percent of the proposed U.S. buildout, far outpacing any other state, according to a new analysis of Clean Air Act permit filings by the Environmental Integrity Project. If all 32 Texas projects ran at full capacity, they could emit more than 287 million tons of greenhouse gases a year, roughly the carbon footprint of 61 million gasoline-powered cars, per the EIP report "The Power Behind AI," released July 1, 2026. The same projects would also release roughly 14,000 tons of particulate matter, 20,000 tons of nitrogen oxides, and 8,000 tons of volatile organic compounds annually — smog-forming pollutants linked in the EIP report to ground-level ozone and fine-particulate exposure in the affected counties.
The 32-project figure is what developers have filed for. The grid planning figure is what ERCOT, the state's grid operator, expects to interconnect. If those two numbers diverge sharply, the discrepancy will land either in permitting denials, in air-quality permitting fights, or in transmission bottlenecks that force developers back to the on-site model. Either way, the carbon math, already large, will keep growing.
KSAT, the San Antonio ABC affiliate, carried the watchdog group's findings as a regional story the same day. The EIP national tally covers plants of at least 100 megawatts whose construction permit applications, draft permits, or final permits name a data center as the primary electricity customer. Every project in the count is in the permit pipeline, not under construction or operating, and most have not broken ground. EIP frames its 74-plant count as a snapshot in time of an expanding pipeline.
The on-site model is what makes the EIP count a permit story rather than a grid story. A data center that builds its own gas plant does not have to wait for transmission upgrades, and it does not show up as load growth in the same way a grid-served campus does. That is also why the emissions math, as EIP presents it, is concentrated in the counties where developers have filed, not the counties where the data centers themselves will sit. Some of the named projects are paired with specific data-center campuses; others are merchant plants selling into a grid whose largest new customer is data centers. The Texas Tribune has tracked gas-to-data-center projects clustering in the West Texas oil patch, part of a wave of large industrial loads that ERCOT is still studying.
Texas's 32 projects are spread across counties from Central Texas to the Permian Basin. EIP's Texas inventory lists Comal, Anderson, Bexar, Pecos, and Caldwell among the named sites. The single largest data-center power-plant air permit issued in the country sits in Pecos County: the GW Ranch project, developed by Pacifico Energy, which the turbomachinery trade press reported cleared Texas air permitting in 2026.
The link between the proposed buildout and local health outcomes is association, not measurement. None of these plants are operating yet, and Texas has not yet been forced to choose between its data-center demand and its existing air-quality obligations in the affected counties. The criteria pollutant totals — 14,000 tons of particulate matter, 20,000 tons of nitrogen oxides, and 8,000 tons of volatile organic compounds per year at full output — are what the plants could emit, not what they do emit today.
