## Key facts

- **San Antonio Clean Air Act lawsuit (Sep 2026):** Reported Sep 21 2026: Environmental Integrity Project, Sierra Club, and Public Citizen sued VoltaGrid and Vantage in federal court alleging two San Antonio AI data center campuses with dedicated gas-fired plants (reported ~405 MW gas + 151 diesel backup generators) used Texas minor-source fast-track permits instead of major-source Clean Air Act permits requiring best available controls and public participation. Groups seek halt of construction/operation until proper permits. Plaintiffs' complaint; not a court judgment
- **Vantage >1 GW off-grid generation partnership (partner press):** Vantage Data Centers and VoltaGrid announced a partnership to deploy more than one gigawatt of natural-gas power generation for Vantage's US data center portfolio, framed as modular off-grid capacity where utility interconnects lag ([Vantage](https://vantage-dc.com/news/vantage-data-centers-and-voltagrid-establish-partnership-to-deploy-more-than-one-gigawatt-of-power-generation/)).
- **Oracle AI data center power collaboration (company press PDF):** VoltaGrid published a company press release describing a collaboration with Oracle to power next-generation AI data centers with its modular generation platform ([VoltaGrid PDF](https://voltagrid.com/wp-content/uploads/VoltaGrid-Press-Release_Oracle_October-15th.pdf)).
