Texas Governor Greg Abbott has directed the Public Utility Commission of Texas (PUCT) and ERCOT to conduct a comprehensive review of all data center interconnection requests, adding a new layer of scrutiny to an already strained large-load connection process. The order comes as ERCOT faces an unprecedented wave of demand growth, with more than 466 GW of large-load requests seeking interconnection by 2031. Data centers account for approximately 421 GW, or more than 90% of that total, far exceeding ERCOT’s current peak demand which recently reached a record 91.1 GW.
Batch Zero Timeline Put on Hold
The governor’s directive is expected to slow implementation of ERCOT’s new large-load interconnection framework. ERCOT had been preparing to notify participants in its transitional Batch Zero process by August 7 whether their projects would qualify as “base load” projects eligible for energization with minimal additional review or as “allocated load” projects requiring further study. Following Abbott’s order, ERCOT announced it would postpone those classification notices and delay the Batch Zero transmission planning study while it works with the PUCT to determine how the audit requirements will be incorporated into the process.
Policymakers Seek Additional Consumer Protections
The move reflects growing concern among Texas policymakers that rapid data center development could create unintended costs for consumers and local communities. Abbott acknowledged recent actions taken by ERCOT and the PUCT — including requiring large-load customers to fund their own infrastructure, strengthening screening criteria, improving long-term planning, and requiring certain facilities to reduce demand during grid emergencies — but indicated that additional safeguards are necessary before projects move forward.
Under the new directive, regulators will gather detailed information on each project’s financial support, power supply strategy, water usage, community impacts, and ownership structure. Data center developers will be required to disclose whether they are relying on state incentives, how much electricity and water they expect to consume, whether they plan to develop on-site generation resources, and what measures they are taking to mitigate impacts such as noise, traffic, and strain on local infrastructure. The review also seeks greater transparency around project ownership and controlling interests.
Implications for Energy Markets and Infrastructure Planning
For energy market participants, the decision signals that Texas is shifting from simply accommodating large-load growth to actively managing it. While the state remains committed to attracting data center investment, policymakers are increasingly focused on ensuring new projects do not compromise grid reliability, increase costs for existing customers, or burden local communities. The resulting delays to Batch Zero may create near-term uncertainty for developers, utilities, generators, and transmission planners, but they also highlight the growing regulatory attention being paid to the long-term implications of massive data center expansion across the ERCOT footprint.
Batch Zero Update (July 2026 TAC)
ERCOT’s preliminary review indicates that approximately 205 GW of large load requests are currently eligible for inclusion in the Batch Zero interconnection study, highlighting the significant scale of data center and other large-load development activity across Texas.
Key preliminary findings (as of July 28, 2026):
- 150 projects (65.4 GW) are eligible for inclusion as Base Load.
- 49 projects (25.5 GW) are eligible for inclusion, with ERCOT still determining whether they will be classified as Base Load or Studied Load.
- 127 projects (114.0 GW) are eligible for inclusion as Allocated/Studied Load.
- 47 projects were deemed ineligible because required dynamic models were not submitted by the July 10 deadline.
- 315 projects (20.5 GW) were excluded because they lacked a qualifying interconnection study.
Upcoming Milestones
- August 7: ERCOT issues final Batch Zero classifications and begins any dispute process for reclassified loads.
- August 31: Deadline to resolve dynamic model deficiencies.
- September 2: ERCOT communicates final eligibility determinations and begins the Batch Zero interconnection study.
- April 9, 2027: Planning Guide Revision Request (PGRR) 145 implementation period concludes.
Market Implications
The preliminary results reinforce the extraordinary volume of large-load demand seeking interconnection in ERCOT, driven largely by data center development. While more than 200 GW appears positioned for Batch Zero consideration, the substantial number of projects excluded due to missing studies or modeling requirements underscores ERCOT’s effort to apply stricter screening criteria and improve planning certainty as Texas manages unprecedented load growth.
