ERCOT Hits Pause on Texas Data Center Queue. How Worried Should AI Infrastructure Investors Be?
Texas Governor Greg Abbott’s August 3 directive for an audit of ERCOT’s data center interconnection queue has introduced uncertainty for AI and bitcoin mining infrastructure investments in the state. The audit pauses classification notices for projects awaiting grid connection, but no projects have been denied yet.
ERCOT (Electric Reliability Council of Texas) manages the state’s independent power grid. Large electricity users must apply for interconnection studies, which verify that local transmission lines can handle the load. The queue ballooned to about 474 GW by July 29, 90% from data centers—more than five times Texas’s peak demand of 91,089 MW.
Senate Bill 6, enacted in 2025, sought to reduce the backlog by requiring projects over 75 MW to prove site control and post financial security of $50,000 per megawatt. In June 2026, ERCOT approved the “Batch Zero” framework to study large-load projects in groups. Around 205 GW qualified, with classification notices scheduled for August 7.
Governor Abbott’s August 3 order, prompted by concerns over households subsidizing data center infrastructure, directed PUCT and ERCOT to audit all data centers in the queue. ERCOT then delayed the classification notices, pending PUCT approval at its August 20 open meeting. The audit covers power draw, on-site generation, water usage, tax incentives, ownership, and community impact.
Impact varies by project stage:
- Capacity that has already completed studies or signed interconnection agreements is unaffected. Approved Texas capacity has become scarcer, as noted by Bernstein.
- Projects still waiting for Batch Zero allocations face genuine timeline uncertainty for 2027, though no cancellations have occurred.
- Projects generating their own power on-site (e.g., new gas turbines) may be structurally unaffected, but the audit’s application to projects with both on-site generation and grid backup remains unclear. Co-location next to existing plants faces stricter curtailment rules, as shown by a July 23 PUCT decision.
The sell-side reaction has been selective, with some target-price trims but no downgrades to sell or project cancellations. Investors should monitor the August 20 PUCT meeting: if a new classification date is set, the episode may prove temporary; if no deadline is given, some developers might withdraw from Batch Zero and demand deposit refunds.
In summary, the audit aims to separate real projects from placeholders, a filter the industry has requested. Approved capacity has become more valuable, pending allocations lack visibility, and prospective tenants may delay decisions. The concrete effects so far are limited to one administrative postponement.
