Texas is about to run its first fully batched large-load interconnection study. Developer submissions for the inaugural Batch Zero cycle closed July 10. The next hard date is July 24, when transmission and distribution utilities must file the complete eligibility package (load information forms, attestations, stability study data) with ERCOT. Miss that window and the project falls out of Batch Zero.
The framework itself was approved by the Public Utility Commission of Texas on June 18. It replaces the one-project-at-a-time study process with a system-wide model: ERCOT studies all qualifying large loads together, determines what the transmission grid can support, and produces a coordinated six-year build plan. Each accepted project ends up with two allocations, a Low Power Consumption number (firm, no curtailment) and a Maximum Power Consumption number (full requested load). Phase 1 study results, including the year-one-through-six megawatt allocations, are targeted for April 9, 2027.
The rule catches any facility with 75 MW or more of combined peak demand at a single site. A subset, Large Computational Loads, covers sites where at least half of demand is power-electronic equipment: data centers, crypto mines, and similar. Those loads carry extra ride-through obligations on top of the batch process.
Two things about this are worth flagging for the interconnection thesis.
First, the queue pressure this is designed to absorb is real. ERCOT reported 198 GW of large-load applications filed in the first quarter of 2026 alone, and the running large-load queue crossed 238,000 MW earlier in the year, with data centers making up roughly 77% of the tracked load. Individual studies were never going to clear that volume on a useful timeline. The batch shift is Texas trying to move interconnection from a project-by-project bottleneck to a portfolio problem the transmission planner can actually solve.
Second, this is one of the cleaner interconnection reform experiments in the country. FERC’s Order 2023 pushed grid operators toward cluster studies for generation. Batch Zero applies the same logic to large loads, at state-jurisdictional level, with the added step that ERCOT explicitly ties the study to a downstream transmission construction plan. If it works, expect PJM and MISO to face pressure to run something structurally similar on the load side.
The risks are the usual ones. Cluster and batch processes concentrate developer risk into single windows: one filing miss, one deficiency not cured by the August 31 deadline, and the project is out until the next cycle. The March 1, 2027 commitment deadline is another cliff, requiring executed interconnection agreements. Whether the framework holds up under that many hard gates is the thing to watch across the fall.
For the supply-chain thesis, this matters mostly because it decides how fast Texas-sited AI and hyperscale demand can actually pull power. That timing feeds back into how quickly storage, gas, and behind-the-fence generation additions get planned into ERCOT’s build. The July 24 filing is the first real read on whether developers and utilities can execute inside the new gates.
