ERCOT Board Endorses ‘Batch Zero’ Rules to Study 100 GW of a 450 GW Data Center Load Queue

The board of the Electric Reliability Council of Texas (ERCOT) endorsed its “Batch Zero” large-load interconnection framework on June 2, 2026, approving rules that let the grid operator study as much as 100 GW of new large-load requests — overwhelmingly data centers and crypto-mining facilities — in grouped batches rather than one at a time. CEO Pablo Vegas told the board the new process could serve as a template for other grid operators, as ERCOT confronts roughly 450 GW of total large-load interconnection requests against a grid whose all-time peak demand is about 85.5 GW.

What Was Approved

ERCOT’s board approved two packages on June 2. The first establishes new criteria and a batch-study process for bringing large electricity users onto the grid: instead of evaluating each request individually, ERCOT will process up to 100 GW of the queue in a prioritized first batch — “Batch Zero.” The second package requires data centers and cryptocurrency-mining facilities to ride through brief voltage and frequency disturbances or disconnect, an effort to prevent the simultaneous load losses that can cascade into wider outages. Both decisions now go to the Public Utility Commission of Texas (PUCT) for review before they are finalized.

Why It Matters

The roughly 450 GW of requested large-load capacity is more than five times ERCOT’s 85.5 GW all-time peak demand, a queue figure that is mostly speculative but impossible to study one project at a time. Batching lets ERCOT triage which projects are real and how they cluster geographically, so transmission planners can size upgrades against committed load instead of discovering it late. Vegas’s framing — that Batch Zero could be a template for other RTOs and ISOs — matters because every large grid operator, from PJM to MISO, faces the same data-center-driven queue explosion. Texas, which runs its own islanded grid, is moving first.

Critical Perspective

Board endorsement is not the final word: the PUCT still has to review and finalize both rule packages, and the details of how projects qualify for Batch Zero will determine who jumps the queue and who waits years. Developers have warned that strict ride-through or disconnect requirements could put billions in planned projects at risk, while consumer advocates worry that prioritizing the largest loads entrenches data centers ahead of other customers. The framework’s real test is whether batching actually filters speculative requests out of the 450 GW figure — or simply reorders a queue that remains five times larger than the grid can serve.
