CURRENT PUBLIC SIGNAL
What we know now
San Antonio remains an operating and construction market. A federal Clean Air Act lawsuit filed September 21 challenges permitting for power plants supporting Vantage TX11 and TX21; the allegations have not been adjudicated.
This is a working local record. Status reflects public announcements, filings, construction reports, and operating information available on the review date—not a guarantee that every proposed phase will be built.
State permit audit: Since September 21, 2026, TCEQ has paused data-center-related permit approvals while the ERCOT and Texas Water Development Board audits proceed. A filing, registration, or local approval does not establish that every required state authorization has been issued.
PROJECT SNAPSHOT

Vantage Data Centers / VoltaGridEnvironmental groups allege the supporting gas-fired generation requires major-source permits. The complaint is an allegation, not a court finding.
