SpaceX Sets 2027 Deadline for Colossus Turbine Removal
SpaceX agreed on Thursday to remove all 69 temporary gas turbines at its Southaven power site by July 2027. Gizmodo reports that removals could begin in August as a permitted 1.2 GW natural-gas plant comes online. The agreement follows litigation by the NAACP and Southern Environmental Law Center over the turbines' permitting status.
SpaceX has agreed to remove 69 temporary gas turbines powering part of the Colossus AI data center complex in Southaven, Mississippi, with the final units scheduled for removal by July 2027. Gizmodo reports that the agreement with the Mississippi Department of Environmental Quality permits removals to begin as early as August while a 1.2 GW permanent natural-gas power plant is brought online.
The Southaven site is near Colossus 2 in Memphis, Tennessee. According to Gizmodo, the Colossus facilities train and serve xAI's Grok models, and SpaceX has also agreed to lease compute capacity to Anthropic. TechCrunch reports that SpaceX is currently operating 69 gas turbines at the site, many of which have operated for months.
Permitting dispute and replacement plant
The temporary turbines have been the subject of a Clean Air Act dispute. Gizmodo reports that the NAACP and Southern Environmental Law Center sued xAI in April, alleging that it was operating 27 turbines without permits at that time and causing pollution in nearby communities. TechCrunch reports that the groups challenged the wider use of the unpermitted turbine fleet.
According to Gizmodo, SpaceXAI has argued that turbines mounted on flatbed trailers qualify for a temporary-mobile exemption from air permitting for up to one year. TechCrunch reports that federal regulations require permits for turbines of this scale and use regardless of whether they remain on trailers.
SpaceXAI described the replacement facility in a statement reported by Gizmodo: the 1.2 GW plant under construction is to comprise 41 permanent turbines authorized under a Clean Air Act permit granted in March 2026. TechCrunch similarly reports that the company is transitioning to a permanent 1.2 GW natural-gas plant.
The Justice Department intervened in the NAACP litigation last month, according to TechCrunch, characterizing the turbine matter as involving national, economic, and energy security.
Compute expansion raises power questions
Data Center Dynamics reports that Elon Musk appears to have confirmed construction of a fourth Memphis-area data center, called Minihard, with the same 220,000 GB300 GPUs and 800 Gb/s NICs described for Macroharder. The outlet notes that a deployment at that scale would likely require more than 400 MW, while its review of January satellite imagery found cooling equipment capable of managing 350 MW. Those figures are Data Center Dynamics' estimates and observations, not a confirmed capacity statement from SpaceXAI.
For AI infrastructure teams, the case illustrates a recurring constraint in frontier-scale training clusters: compute deployment schedules can outpace interconnection and permitted generation capacity. Comparable large data center projects often combine utility power, on-site generation, and temporary equipment, but environmental permitting can become a binding operational constraint when temporary systems remain in service for extended periods.
The July 2027 deadline leaves a long overlap between the temporary fleet and construction of the permanent plant. Public reporting does not establish how much of the Colossus load each power source serves at each stage, nor does it provide a verified timetable for the reported additional GPU deployment.
Key Points
- 1SpaceX's agreement sets a July 2027 endpoint for 69 temporary turbines supporting the Colossus-area AI data center complex.
- 2A permitted 1.2 GW natural-gas plant is replacing the temporary fleet, linking AI compute expansion to generation and air-permit timelines.
- 3Comparable frontier data center builds often encounter permitting constraints when temporary power infrastructure remains operational beyond initial deployment periods.
Scoring Rationale
The agreement concerns power infrastructure for a major AI training and inference campus, where electricity availability directly limits accelerator deployment. It is also a notable example of environmental permitting becoming material to data center operations, though it does not introduce a new AI model or developer product.
