⭐ Morning Briefing — September 22, 2026

Top Story: Gov. Greg Abbott ordered the Texas Commission on Environmental Quality on Monday to stop issuing any new data center permits statewide until ERCOT, the PUC and the Texas Water Development Board finish auditing the industry's power and water demands — his third crackdown on the sector since June, and the first to touch every data center project in the state rather than just those connecting to the grid.

📰 Today's News

1. 🛑 Abbott Halts Every Data Center Permit in Texas, Not Just Grid Connections

Gov. Abbott sent a letter Monday directing TCEQ Executive Director Kelly Keel to halt all permits sought by data center projects until ERCOT and the Texas Water Development Board (TWDB) complete audits of the industry's electricity and water demands. "Simply put, Texans must come first," Abbott wrote. "Data centers must pay their own way, protect our grid and water and complete the ERCOT and TWDB audits. Until they do, TCEQ will issue no permits sought by data center projects."
The order closes a gap in Abbott's earlier actions. His August 3 moratorium only paused new grid interconnections through ERCOT — leaving developers who build their own "behind the meter" power plants free to keep pulling permits without ever facing that audit. Monday's directive brings TCEQ, which issues the air and water permits those on-site plants need, under the same freeze. TCEQ must now weigh the ERCOT/TWDB findings before approving any future data-center-related permit, and the governor's office says the agency owes an update on its permitting decisions by October 19.
The order also lands weeks after a TWDB compliance push: after only 28% of data centers responded to a state-mandated water-usage survey, Abbott directed the TWDB on September 14 to penalize non-reporting projects. Monday's letter folds that water-reporting effort in alongside the ERCOT audit as a precondition for any TCEQ approval. Abbott's office added that next legislative session, the governor will work with lawmakers to "eliminate any financial incentives for data centers."

Today's Signal: Every previous Abbott order in this saga still left one door open for a project to keep moving without ERCOT's sign-off — building your own power plant instead of connecting to the grid. This is the first order that shuts that door too, by freezing the TCEQ permits those plants themselves need.

2. ⚖️ Environmental Groups Sue Vantage and VoltaGrid Over San Antonio's Behind-the-Meter Gas Plants

The Environmental Integrity Project, the Sierra Club and Public Citizen filed a federal Clean Air Act lawsuit Monday against data center developer Vantage and its energy supplier VoltaGrid, arguing two co-located gas-fired power plants serving Vantage's Westover Hills data centers in San Antonio should have been permitted as "major" pollution sources rather than the minor-source permits — the same tier issued to a laundromat — that VoltaGrid obtained instead.
The suit says the two behind-the-meter plants total 405 megawatts of generating capacity, with an additional 151 backup diesel generators capable of adding 455 more megawatts. One of the two data centers, on Rogers Road, was already "partly operational" before TCEQ held its first public hearing on the project, and the area already fails federal smog standards. "Texans increasingly distrust data center developers, and for good reason," said Public Citizen attorney Nandan Joshi. The groups are asking the court to halt construction and operation at both sites until major-source permitting, with its public-comment requirements, is completed.
The case is a direct test of the exact regulatory gap Abbott's Monday order is aimed at closing: Vantage and VoltaGrid used Texas's minor-source classification for on-site generation to avoid both the ERCOT interconnection process and, the suit alleges, the stricter air-permit scrutiny major polluters face.

Today's Signal: This is the same behind-the-meter loophole named in Abbott's letter to TCEQ, but arriving from the opposite direction — instead of a governor's order, it's a federal lawsuit arguing the state's own minor-source permitting process let two gas plants sidestep the pollution controls the Clean Air Act requires.

3. 🔌 Texas PUC Softens Its Final Large-Load Interconnection Rules

The Public Utility Commission of Texas voted Friday to adopt final large-load interconnection standards that are notably lighter than what it proposed in March — eliminating a proposed non-refundable interconnection fee of $50,000 per megawatt of contracted peak demand entirely, and replacing tiered study fees with a flat $100,000 study fee regardless of project size. The PUCT said it may revisit that flat fee "as more data becomes available relating to study costs."
The final rule also loosened the timeline for penalizing large-load customers who miss their energization milestones: the proposed rule required notifying ERCOT within 30 days of a six-month-old missed milestone, but the adopted rule extends that to 24 months, applied to the energization schedule as a whole rather than milestone-by-milestone. A transmission or distribution provider must now apply a large-load customer's financial security to any outstanding balance within 60 days of notifying ERCOT, then return what's left — a change from the proposed rule, which would have let the provider keep 80% of that security as an offset in its own rate case.
The rule takes effect as ERCOT's audit of its roughly 474-gigawatt interconnection queue continues — a queue that is, by ERCOT's own estimate, about 90% data centers.

Today's Signal: The PUC finalized this rule the same week Abbott tightened permitting on the other end of the process — a reminder that "the state is cracking down on data centers" isn't one uniform story; regulators are simultaneously easing some financial terms for large loads even as the governor's office tightens permitting and audit requirements around them.

4. ⛽ Kodiak Gas Services Signs Second Data Center Power Deal, This Time in West Texas

Houston-area contract-power provider Kodiak Gas Services announced a six-year deal Monday to supply 76 megawatts of behind-the-meter baseload power to a West Texas data center, deploying about 40 natural-gas-fueled reciprocating generation units beginning in the fourth quarter of 2026 and scaling through the first quarter of 2027.
Kodiak said the unnamed data center operator has a lease guaranteed by a GPU designer and a contract with an "investment-grade-rated hyperscaler," though none of the three parties were named. CEO Mickey McKee called it the company's second long-term contract to supply primary power to a data center and said Kodiak is targeting 2 gigawatts of power-generation capacity by 2030.
The deal is a small-scale, single-site version of the same on-site generation strategy now facing federal legal scrutiny in San Antonio and tighter state permitting under Monday's TCEQ order — underscoring how central behind-the-meter gas power has become to data center buildout across the state, not just in the DFW-area fights this briefing usually tracks.

Today's Signal: Three of today's four stories touch behind-the-meter gas generation from a different angle — a governor's order, a federal lawsuit and now a routine equipment contract — which says less about any one company and more about how central that strategy has become to how Texas data centers get built.

Quiet today on new DFW county zoning votes and land-acquisition announcements — Monday and Tuesday's developments were all regulatory, legal and contractual rather than local.

📍 Today's Watch List

TCEQ owes an update on its data-center permitting decisions by October 19, per Abbott's Monday letter — the first concrete deadline to watch for how the agency applies the new freeze.
How Vantage and VoltaGrid respond to the federal Clean Air Act suit, and whether the environmental groups' request to halt construction and operation at the two San Antonio sites gets an early hearing.
Whether the PUC revisits its new flat $100,000 study fee "as more data becomes available," per the language in Friday's adopted order.
Whether Abbott's stated plan to work with the Legislature next session on eliminating data center financial incentives produces actual bill language once lawmakers convene.
Whether other operators follow Kodiak's and VoltaGrid's lead in signing standalone behind-the-meter power contracts now that on-site generation is drawing both regulatory and legal attention.
ERCOT's December 10 audit-completion deadline and the roughly 250-300 projects in its first review batch — no material movement expected before the December PUC meeting, so this stays at the bottom of the list until that date approaches.
