SemiAnalysis identifies 8.7 GW of Texas datacenter campuses exposed to permit freeze

• Six Texas datacenter campuses totaling 8.7 GW need air permits during the pause, according to SemiAnalysis.
• That headline is a blunt delay estimate: the firm's breakdown includes three campuses with initial generation already permitted.
• On-site power now falls under the expanded freeze, closing the grid-interconnection workaround described by SemiAnalysis.
• A December permitting restart remains SemiAnalysis's base case, with roughly one-quarter delays for phases needing permits soon.

ERCOT's audit request reaches into ownership, cooling technology, noise and traffic. TCEQ's electronic reporting system was temporarily shut down amid a separate dispute over construction authorizations.

Texas Governor Greg Abbott's September 21, 2026 directive ordered the Texas Commission on Environmental Quality (TCEQ) to halt datacenter-related permit issuance until the Electric Reliability Council of Texas (ERCOT) completes its review.

The August pause covered grid interconnections, leaving campuses building their own behind-the-meter generation untouched. SemiAnalysis says TCEQ has confirmed that the expanded freeze also covers their air permits.

The 8.7 GW aggregates full campus capacity across three permitting stages in SemiAnalysis's breakdown:

• Three campuses: Initial generation is already permitted; expansion permits remain outstanding.
• One campus: An application has been filed and awaits approval.
• Two campuses: Applications have yet to be filed.

The public thread gives campus counts by status, while reserving the campus names, phases and exposed megawatts for the firm's Datacenter Industry Model.

An air-permit hold gates the power plant. Under that hold, site work and generation already permitted can keep moving, according to SemiAnalysis.

A three-month pause in issuance becomes a delivery delay where a campus needs to start building its plant before the review ends.

ERCOT expects to publish its report no later than December 10, 2026. SemiAnalysis assumes TCEQ resumes issuing permits in December, shifting phases that need permits soon by about a quarter while leaving the rest of its forecast intact.

Public Citizen and FracTracker Alliance identified 35 post-directive approvals, according to ABC13's October 23 reporting. TCEQ described them as automated construction-stormwater Notices of Intent.

Public Citizen said 17 datacenter-related authorizations had subsequently been suspended. Those authorizations allow land clearing, grading and excavation, introducing a separate permitting issue for site preparation alongside the power-plant air permits in SemiAnalysis's analysis.

SemiAnalysis describes four inputs it tracks when forecasting datacenter construction:

• Preleases: Contracts signed by hyperscalers, neoclouds and AI labs, which the firm describes as binding and noncancelable.
• Groundbreaking and site work: Early construction activity, including contractor Sterling's orders. SemiAnalysis says it anticipated an order surge that subsequently materialized.
• Electrical and cooling equipment: Deliveries following the initial site work.
• Power equipment: Gas turbines with lead times measured in multiple years.
