xAI Expands Gas Turbines to 46 While Facing Clean Air Act Lawsuit

xAI added 19 natural gas turbines to its Southhaven, Mississippi data center between late March and May 2026, raising total capacity to 46 units. The expansion occurred after the NAACP filed suit on April 14 alleging 27 existing turbines violated the Clean Air Act by operating without proper air permits. Internal emails obtained by the Southern Environmental Law Center confirm the additions proceeded despite active litigation over the facility's compliance.
