Texas Regulators Approve ERCOT Batch Process for AI Data Center Power Requests
Texas utility regulators approved ERCOT’s new process for reviewing power connection requests from large electricity users, marking a major change in how the state will manage surging demand from AI data centers and other energy-intensive facilities.
The Public Utility Commission of Texas on June 18 approved the grid operator’s “Batch Zero” framework, which will group qualified projects of 75 megawatts or more into a single study rather than evaluating them one by one. ERCOT said the change is intended to determine how much new demand the grid can reliably absorb, where it can be located and what transmission upgrades would be needed.
The approval comes as Texas faces an unprecedented wave of proposed large-load projects. ERCOT said it is tracking more than 438,000 MW of large-load requests, with nearly 89% coming from data centers. That queue is more than five times ERCOT’s all-time peak demand of 85,508 MW, recorded in August 2023, underscoring how much of the pipeline is unlikely to be built in full but also how quickly AI infrastructure demand has begun to reshape grid planning.
“Texas is experiencing an energy transformation unlike anything we have seen before,” ERCOT Chief Executive Officer Pablo Vegas said in the announcement. The new process, he said, gives ERCOT a more structured and transparent way to manage large-load interconnection growth while protecting reliability.
Batch Zero is the first group of large-user applicants to go through the new framework. ERCOT expects to notify applicants of their project classification in August 2026. A final transmission plan covering the batch is expected in fall 2027, while applications for the next group, Batch 1, are expected to open in summer 2027.
The framework replaces a project-by-project review system that ERCOT said had become slow and repetitive as large users rushed to reserve positions on the Texas grid. The old approach also made it harder for planners to assess the combined effect of many large facilities seeking power in the same region.
Large-load requests have become a growing challenge for grid operators across the US as cloud providers, AI companies, bitcoin miners and industrial users compete for power access. In Texas, the issue is particularly acute because ERCOT operates most of the state’s grid and has seen developers target the market for its large energy resources, relatively fast permitting environment and existing concentration of digital infrastructure.
The state’s response has increasingly focused on separating viable projects from speculative requests and limiting the risk that ordinary ratepayers are left paying for transmission upgrades built for projects that never materialize. Texas Senate Bill 6, passed in 2025, directed regulators to develop new interconnection standards for large loads of 75 MW or more, including financial and disclosure requirements meant to improve planning and reduce stranded infrastructure costs.
ERCOT’s Batch Zero framework fits into that broader regulatory shift. The process requires large projects to meet maturity and commitment criteria before being studied, allowing ERCOT to assess the reliability impact of the group on a system-wide basis. The framework was reviewed through ERCOT’s stakeholder process and approved by several internal committees and the ERCOT board before PUCT consideration.
The process also creates alternative pathways for large users that can reduce their draw on the grid. Customers that build onsite generation to self-supply some or all of their electricity may receive different treatment, while projects that are fully islanded from the grid generally fall outside ERCOT’s interconnection process, though they may still face PUCT registration requirements.
Another pathway allows large customers to connect if they agree to let ERCOT curtail their electricity use in response to local transmission constraints. That could make certain data centers and other large loads more flexible than traditional industrial demand, giving ERCOT another tool to manage congestion and reliability risks.
The approval also comes as federal regulators are pushing other US grid operators to reassess how they handle large-load interconnections. The Federal Energy Regulatory Commission last week ordered regional grid operators under its jurisdiction to justify or reform their tariffs for data centers and other large energy users. ERCOT is largely outside FERC’s jurisdiction because most of the Texas grid is not synchronously connected to other states, making the PUCT’s decision one of the most closely watched state-level responses to the AI power boom.
