SpaceX to Remove Unpermitted Turbines Powering xAI Colossus Data Center
The company will replace 69 temporary generators with a permanent 1.2 GW power plant by 2027.
SpaceX has agreed to remove 69 unpermitted, trailer-mounted gas turbines currently powering the xAI Colossus data center near Memphis, Tennessee. The move follows legal challenges over the company's use of temporary power infrastructure to fuel one of the world's largest AI training facilities.
According to company plans, the removal process is expected to take up to a year, with a target completion date of July 2027. These temporary generators, which operated without state or federal air permits, are being replaced by a permanent 1.2-gigawatt (GW) natural gas power plant currently under construction in Southaven, Mississippi. This permanent facility will consist of 41 gas turbines with individual capacities ranging from 16.48 MW to 50 MW.
The Regulatory Conflict
The use of the temporary turbines sparked significant opposition from the NAACP and the Southern Environmental Law Center (SELC). These organizations argue that the installations violate the Clean Air Act and disproportionately impact predominantly Black communities in northern Mississippi. Despite these challenges, the U.S. Department of Justice (DOJ) intervened by filing a statement of interest in support of SpaceX. The DOJ argued that a rapid removal of the turbines would threaten "national, economic, and energy security," effectively siding with the company's need for immediate power.
Industry Implications
This case underscores the growing tension between the massive energy requirements of the AI boom and existing environmental regulatory frameworks. The DOJ's intervention suggests a federal priority to expedite AI infrastructure, potentially creating a precedent where data center operators can bypass traditional permitting processes by utilizing "temporary" equipment to maintain operational speed. The scale of this investment is further highlighted by SpaceX's own IPO filings, which disclosed plans to spend over $2.8 billion on gas turbines for its data centers over the next three years.
What's Next
Observers will now monitor whether the transition to the permanent Southaven plant meets the July 2027 deadline and if the new facility satisfies the environmental concerns raised by local advocacy groups. While the DOJ has provided a temporary shield for the current operations, the long-term legal standing of such "temporary" workarounds remains a point of contention for environmental regulators.
