SpaceX-owned xAI faces Clean Air Act suit over 27 Mississippi gas turbines totaling about 495 MW

SpaceX’s wholly owned subsidiary xAI has deployed 27 gas turbines in Southaven, Mississippi, with a combined capacity of about 495 megawatts. The NAACP has sued, alleging the turbines were installed without permits and emit more than 1,700 tons of nitrogen oxides a year in violation of the Clean Air Act. The U.S. Justice Department has moved to intervene and seek dismissal on national security grounds, and a hearing is scheduled for August. The complaint seeks penalties of up to $124,426 per day, creating a material legal and financial risk for SpaceX’s AI operations.
