Environmental groups have sued Vantage and VoltaGrid in federal court for operating major pollution sources under minor-source permits, alleging the off-grid data center projects in San Antonio threaten local air quality and bypass required public input.

  • Yahoo reports that the gas-fired facilities are off-grid with a combined 405 MW capacity, supplemented by 151 diesel backup generators, while the plaintiffs argue the sites are already located in an area failing federal smog standards.
