Texas Grid Audit Freezes Data Centre Queue As AI Demand Builds

Texas has turned its data-centre buildout into a grid audit rather than a straight approvals race, Capacity reported, after Governor Greg Abbott ordered ERCOT and the Public Utility Commission of Texas to verify large-load projects before new facilities move forward.

The pause is narrower than early coverage suggested.

It applies to projects inside Batch Zero, ERCOT's new early review channel for large interconnection requests, rather than every project in the grid operator's queue.

Even with that narrower boundary, the review reaches one of the largest concentrations of AI infrastructure demand in North America.

Batch Zero Puts 250 To 300 Projects Under Review

Abbott's 3 August directive requires ERCOT and PUCT to conduct a comprehensive verification and audit of data-centre projects moving through the interconnection process.

Projects that fail state-law or regulatory checks face denial of grid access, and no new data centre can proceed until the audit is complete.

ERCOT's broader queue has grown beyond 1,800 projects seeking about 474GW of capacity, a scale far above the grid's historic peak.

Data centres make up about 90% of the requested load, turning AI computing demand into a direct planning problem for power infrastructure rather than a distant technology forecast.

At a 14 August emergency meeting, ERCOT officials put the Batch Zero audit at between 250 and 300 projects, mostly data centres with some other large-load users such as factories included.

The projects represent about 200GW of future demand, more than twice ERCOT's peak-demand record from the previous month.

PUCT chair Thomas Gleeson framed the exercise around certainty and confidence in Batch Zero, not a permanent cancellation of the process.

Power, Water And Cost Exposure Move Into The File

The review goes beyond whether a substation or transmission path can connect a site.

Regulators have been told to assess how much infrastructure data-centre developers will fund themselves, whether a project brings its own power or relies on the grid, how it sources or reuses water, what community-impact controls it has, who owns the project and what tax incentives it receives.

That scope links interconnection approval to the financing and local-resource questions that have followed AI data centres across several US markets.

Texas had marketed itself as a low-friction destination for developers, with cheap power, lighter regulation and faster permitting.

A state-level pause changes the risk calculation because it comes from Austin and grid regulators rather than only from county-level opposition.

20 August Meeting Sets The Next Step

ERCOT had been expected to notify developers on 7 August which projects entered the initial Batch Zero study, but that notice was shelved.

The missed notification gives the audit a practical consequence for project financing, because developers cannot treat study entry as confirmed while the review remains open.

On 10 August, the grid operator filed for good-cause exceptions to extend Batch Zero deadlines, with a formal request due at the PUCT's 20 August open meeting.

The timetable after that remains open.

ERCOT has told regulators the audit could take several months, leaving developers, lenders and equipment suppliers to plan around an interconnection process without a fixed completion date.

The uncertainty arrives as North American data-centre absorption reached 25GW in the first half of 2026, double the year-earlier level, with Texas driving a large share of growth.

Water may become the most visible constraint in the review.

Texas data centres account for about 0.4% of statewide water consumption today, while researchers expect the share could reach 2.7% by 2030.

The water-share figures place local resource accounting alongside electricity demand in the Batch Zero review.
