Texas ERCOT grid operator halts data center approvals due to 474 GW interconnection queue; Gov. Abbott orders infrastructure audit

Governor Greg Abbott has called for an audit of all data center projects in the Electric Reliability Council of Texas interconnection queue, citing concerns that the scale of development "could endanger the reliability and stability of the Texas electric grid." The move has prompted ERCOT to delay its Batch Zero review process, with the grid operator announcing plans to request a good-cause exemption to the timeline at its August 20 open meeting with the Public Utility Commission of Texas.

Abbott's directive requires that any data center project failing to comply with the verification and audit process be denied. The order comes amid an estimated 474 GW of interconnection requests—a volume that has triggered unprecedented scrutiny of whether the grid can accommodate the demand from AI-driven infrastructure development.

The Texas pause follows similar action in New York, where regulators halted new data center approvals in July while developing updated development rules.

The Data Center Coalition, representing industry members, expressed cautious support for the audits, viewing them as a mechanism to distinguish responsible operators from speculative players. Dan Diorio, the group's executive vice president of state policy and government affairs, said: "With billions of dollars in investment and hundreds of thousands of jobs on the line, we urge the PUCT and ERCOT to move swiftly in order to distinguish between speculative projects and serious, committed investors and community partners." Diorio added that if handled well, the audit "can showcase the good actors in the data center industry rather than delaying them unnecessarily, ensuring Texas will continue to be the national leader in economic development."

In May, ERCOT published a preliminary forecast suggesting peak demand could more than quadruple by 2032, driven by data centers and other large load customers—though the grid operator cautioned that the forecast may be inflated due to speculative projects.

Law firm Troutman Pepper Locke characterized the pause as a "delay of indeterminate duration" with significant implications. The firm cautioned that power generation and infrastructure investors financing transmission, generation, or grid infrastructure tied to large-load projects should reassess how the suspension affects project viability, lender security interests, and capital deployment schedules, including counterparty termination rights. Similarly, tech companies and hyperscalers evaluating Texas projects should reassess development timelines and prepare for new disclosure and compliance requirements governing future interconnection approvals.

Virginia currently leads the nation in data center development, followed by Texas. Industry participants believe Texas can still overtake the top spot despite the regulatory pause.
