Texas moves to screen data centers before they connect to its power grid

Abbott froze environmental permits weeks after pausing grid connections, and ERCOT now aims to finish its audit by December 10

Overview

Updated Oct 23

Texas has widened its freeze on data centers from the power grid to environmental permits. On September 21, Governor Greg Abbott told the Texas Commission on Environmental Quality to stop approving data center permits until the Electric Reliability Council of Texas finishes auditing the projects waiting to connect.

ERCOT told regulators it aims to send that audit to the Public Utility Commission by December 10. Watchdog groups counted 35 permitting actions at the environmental agency after the order. The agency says it has approved none.

Why it matters

Data centers behind the AI boom now need Texas's approval on water and air permits, not just a grid connection.

  1. Watchdogs count 35 TCEQ permitting actions since the halt

    Latest Report

    FracTracker Alliance and Public Citizen say TCEQ kept processing data center paperwork after September 21, including stormwater coverage, emissions estimates and preliminary approval notices for gas plants serving the projects. TCEQ says it has approved no permits and has paused applications covered by the directive.

  2. Abbott halts environmental permits for data centers

    Directive

    Abbott directs the Texas Commission on Environmental Quality to hold all data center permits until ERCOT finishes its audit, extending the pause from grid connections to air, water and stormwater permitting. A New York Times report the next day describes the shift from his earlier welcome for the industry.

  3. Abbott orders a water-use crackdown on data centers

    Directive

    The governor directs the Texas Water Development Board to compel data centers to comply with water-use reporting, impose penalties for past and future noncompliance, and work with ERCOT on the audit.

  4. PUCT directs ERCOT on the audit

    Regulatory Action

    At its open meeting, the commission takes up ERCOT's good cause exception and gives direction on verification scope, mechanics and timing. ERCOT officials say they aim to file a verification report by December 10, and that Batch Zero study results will miss the April 9, 2027 deadline.

  5. ERCOT files for a deadline extension

    Regulatory Filing

    ERCOT requests a good cause exception to extend Batch Zero deadlines and accommodate the audit, having already suspended the August 7 classification notices.

  6. Abbott orders a data-center audit

    Directive

    The governor directs PUCT and ERCOT to verify and audit every data-center project in the queue before any advance. ERCOT pauses Batch Zero the same day.

  7. Gleeson letter to the governor

    Statement

    The PUCT chair outlines steps already taken and warns that new legislation would be needed for broader control of large loads.

  8. PUCT approves Batch Zero framework

    Rule Change

    Regulators approve ERCOT protocol changes creating a batch study process for connecting large loads, with classification notices expected in August.

  9. Abbott signs Senate Bill 6

    Legislation

    The law expands state oversight of large power users of 75 MW or more, including disclosure of backup generation and possible curtailment during grid emergencies.

Scenarios

1

Audit finishes on schedule and Batch Zero resumes

Possible Resolves by May 20, 2027

Discussed by: Baker Botts, Gibson Dunn, and other energy-law analysts tracking the process

ERCOT completes verification within its stated window, most financed projects clear, and the operator restarts Batch Zero classification notices. The pause becomes a delay rather than a lasting barrier, and serious developers keep their place in line.

2

Audit shrinks the queue as speculative projects fall away

Likely Resolves by Q2 2027

Discussed by: PUCT Chair Thomas Gleeson and grid analysts who call the 474 GW figure inflated

The audit exposes many duplicate or unfinanced requests, and the headline queue drops sharply once placeholders are removed. Gleeson has argued the number must be refined into something usable for planning, and the review is the tool to do it.

3

Developers pivot to off-grid power to skip the gate

Possible Resolves by Q2 2027

Discussed by: Beatty & Wozniak and other firms flagging behind-the-meter strategies

Facing a slower front-door queue, at least one major developer announces a large Texas data center powered mostly by dedicated on-site or behind-the-meter generation. That route sidesteps the interconnection audit but shifts reliability risk onto private generation.

4

Legislature hands PUCT broader large-load authority

Uncertain Resolves by Jul 1, 2027

Discussed by: PUCT Chair Thomas Gleeson, who says new legislation is needed

The 2027 legislative session takes up Gleeson's call for stronger tools, passing a law that expands the commission's power over how large loads connect, disclose, and curtail. Abbott signs it, giving the gatekeeping approach a firmer legal footing.

5

ERCOT misses its December 10 filing date

Possible Resolves by Dec 10, 2026

Discussed by: ERCOT senior vice president Chad Seely and the grid operator's filings with the PUCT

The verification report slips, and with it the restart of Batch Zero. ERCOT has already told commissioners it will not finish the Batch Zero interconnection studies by April 9, 2027 and has not set a replacement date, so each delay pushes the first wave of large-load connections further out.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

February 2021

Winter Storm Uri and the ERCOT collapse (2021)

A deep freeze knocked out much of Texas power generation. ERCOT ordered rolling blackouts that left millions without heat for days, and hundreds died. The grid came minutes from a much longer, uncontrolled collapse.

Then

The PUCT's chair and ERCOT's CEO resigned, and the legislature passed a package of grid reforms.

Now

Reliability became the dominant test for any grid decision in Texas, giving regulators political cover to act aggressively.

Why this matters now

Uri is why Texas officials now treat huge new loads as a reliability question first. The audit reflects a grid still wary of promising power it may not have.

July 2022

Dominion pauses Virginia data-center hookups (2022)

In Loudoun County, home to the world's densest cluster of data centers, utility Dominion Energy warned it could not connect some new projects because transmission in the area was constrained. The pause rattled the industry.

Then

Dominion accelerated transmission upgrades and connections resumed within months.

Now

It was an early signal that data-center growth could outrun grid capacity, forcing utilities to ration access.

Why this matters now

Virginia showed the same collision now hitting Texas, but on a smaller scale. Texas is confronting it before wires are strung, not after.

July 2023

FERC overhauls the interconnection queue (2023)

Federal regulators issued Order 2023 to fix clogged national queues where speculative projects tied up study resources for years. The rules added deposits and readiness tests to force out projects that would never get built.

Then

Grid operators began restudying queues and imposing stricter entry requirements.

Now

It set a template: use verification and financial commitment to separate real projects from placeholders.

Why this matters now

Texas is applying that same logic to demand. The 474 GW figure looks like a queue padded with speculative requests, and the audit is the filter.
