xAI Secures Permit for 1.2GW Gas-Fired Power Plant to Fuel AI Data Center Expansion
March 11, 2026
In a move highlighting the intense power demands of the artificial intelligence boom, Elon Musk's xAI has received regulatory approval to construct a major on-site power facility for its growing data center cluster in the Memphis area. The decision by the Mississippi Department of Environmental Quality (MDEQ) grants a Clean Air Act permit for 41 natural gas turbines, underscoring the industry's turn towards dedicated, often fossil-fuel-based generation to secure the massive and reliable electricity required for advanced AI compute.
The MDEQ approved the permit at a meeting on Tuesday, March 10. The turbines will be installed at a former Duke Energy power plant site in Southaven, Mississippi, which xAI purchased in July 2025. With a total capacity of 1.2 gigawatts, this self-generation facility is designed to power the company's existing Colossus 2 data center located just across the state line in Memphis, Tennessee, and a forthcoming Colossus 3 facility planned for Mississippi. In a statement posted on X, xAI said it was "thrilled" by the approval, claiming the permit "not only meets all state and federal permitting regulations but goes above and beyond what is required by law." The company added that the project would ensure "ratepayers don’t pay one extra cent in their energy bills and powers the future of AI innovation through Grok."
xAI's expansion in the region has been rapid. The company launched its first Colossus supercomputer in a Memphis data center in 2024, purchased the site for Colossus 2 in March 2025, and brought that facility online this past January. Musk has stated the overall cluster will eventually provide 2GW of compute power, with the new gas turbines being key to that ambition. The company is also investing $659 million in another building on an adjacent parcel.
The project has faced significant opposition from environmental and community groups. Critics, including the Southern Environmental Law Center, argue the permit process was rushed, with the public meeting announced only five days in advance and held in Jackson, Mississippi, a three-hour drive from the affected communities. Patrick Anderson, a senior attorney at the group, stated, "Mississippi state regulators appear to be more interested in fast-tracking xAI’s personal power plant than conducting a thorough review of its impacts and having meaningful engagement with the families that will be forced to live with this dirty facility - and its pollution - in their communities." Campaigners have also raised ongoing concerns about air quality impacts in what is one of the area's poorest neighborhoods.
The controversy reflects a broader tension as data center developers, particularly in AI, seek to bypass strained public grids with large-scale private generation, often leading to conflicts over environmental justice, regulatory oversight, and the sustainability of the industry's breakneck growth.
