ERCOT closed Batch Zero interconnection submissions on 24 July, with classification results on the Texas data-centre queue due by 7 August.

Key takeaway

ERCOT publishes its Batch Zero classification by 7 August, the first audited count of the Texas queue.

The Electric Reliability Council of Texas (ERCOT), the grid operator running most of the Texas electricity market, closed Batch Zero interconnection submissions on 24 July, with classification results due by 7 August⁠1. Batch Zero is the first tranche under the large-load interconnection process created after Texas legislated on data-centre connections, and classification sorts the applications by how far advanced each project actually is.

ERCOT is the outlier among the six operators that filed generation-adequacy reports this fortnight. It sits outside FERC's jurisdiction, being a grid deliberately kept inside one state's borders, and it has courted large loads rather than rationed them. Where Ofgem proposes a deposit to make speculation expensive, Texas is instead going to publish who is serious.

The Texas Public Utility Commission approved this study process in June, and the classification results are its first output. Nobody believes the whole Texas queue will be built. The results due on 7 August produce the first audited estimate of how much of it might be, in a market that charges nothing to deter a speculative applicant. Whatever share survives classification becomes the reference point every other jurisdiction's queue estimate gets measured against.

Deep Analysis

In plain English

Texas has its own electricity grid operator, ERCOT, separate from the rest of the United States. Many companies have applied to connect huge data centres to that grid, but nobody knows how much of that demand is genuine versus speculative applications that will never actually get built. ERCOT just closed the window for grid companies to submit detailed information on these projects, and will announce by 7 August which ones it classifies as real.

Deep Analysis
Escalation

The scale of Texas's data-centre queue has not eased; ERCOT's own large-load interconnection page put the total queue at 438 GW as of late May 2026, with over 300 GW of that not yet having submitted studies, meaning most of the queue remains unconfirmed pending the 7 August classification.

What could happen next?
  • Meaning

    Batch Zero's 7 August classification results will be the first hard test of how much of Texas's data-centre interconnection queue is genuine demand versus speculative applications.

This Event
ERCOT closes its Batch Zero queue window
Texas is about to publish the first hard count of how much of its data-centre queue is real, in a market that has priced grid access lightly.
Different Perspectives

Seven projects, one linked to Google, asked SEA this month for rulings that they fall outside full environmental review; four declared diesel-storage volumes just under the review-triggering tonnage, mirroring the mechanism Alto Jahuel used in July. The clustering suggests the threshold is being engineered, not sized to need.

Ireland's planning appeals body refused the €1.5bn Killala data centre on 17 September, overturning Mayo County Council's 2025 grant for lack of a fixed grid-connection agreement and no corporate renewable power-purchase agreement. The ruling makes matched-power evidence, not planning consent alone, the deciding factor.

The two groups' 6 August appeal, filed through the Legal Resources Centre, kept Cape Town's approval of Equinix's data centre suspended through this window over missing water, emissions, noise and diesel-generator data. Deputy Mayor Eddie Andrews confirmed on 20-21 September that the suspension holds.

Aragon's economy chief Eva Valle said on 11 September that Spain's draft decree, requiring 80% hourly-matched renewables via a 10-year power-purchase agreement, is unmeetable by any project and threatens Blackstone, Azora and Microsoft builds already under way. Aragon holds 3,600 MW of granted grid access against 108 MW built.

Abbott ordered TCEQ on 21 September to halt every pending data-centre permit until projects pay their own way and complete ERCOT and Texas Water Development Board audits. Texas built the country's most permissive data-centre market; freezing it signals even that market has hit its grid limit.
