SpaceXAI will withdraw all 69 temporary trailer-mounted turbines from its Colossus campus, completing the phased removal by July 2027. The 12-month transition will occur as a permitted 1.2GW on-site power plant comes online. Community complaints, an EPA determination that the turbines are not exempt from permitting, and a NAACP lawsuit prompted negotiations with the Mississippi Department of Environmental Quality. SpaceXAI also says it will equip the mobile units with advanced emission controls during the transition.
SpaceXAI To Remove 69 Unpermitted Mobile Turbines — Full Withdrawal By July 2027 As 1.2GW Plant Comes Online

SpaceXAI has confirmed it will remove all 69 temporary, trailer-mounted turbines deployed around its Colossus data center campus near the Tennessee–Mississippi border, beginning this month and finishing by July 2027. The company says the withdrawal will be carried out in phases over roughly 12 months while a permanent, permitted 1.2GW on-site power plant is brought online.
The Colossus sites achieved an unusually rapid build-out: SpaceXAI installed 100,000 Nvidia H200 GPUs in just 19 days, a deployment pace Nvidia CEO Jensen Huang has said typically takes years. That speed was enabled by using on-site portable power instead of waiting for conventional grid connections, a tactic now being copied by some other large operators.
Community Concerns and Regulatory Pushback
Local residents and community groups have long complained that the mobile turbines caused pollution and operated without required permits. SpaceXAI maintained the units were exempt because they were temporary and mobile, but the EPA determined the turbines do not qualify for a permit exemption. Despite that guidance, the turbines continued operating while legal and regulatory disputes progressed.
Legal Action and National Security Concerns
The dispute escalated when the NAACP filed a lawsuit over the unpermitted turbines. The Department of Justice intervened, warning that an immediate removal could pose national security risks because Colossus 2 "supports mission-critical operations." That concern factored into negotiations between the company and regulators.
Agreement And Transition Plan
SpaceXAI says it has reached an agreement with the Mississippi Department of Environmental Quality. The replacement 1.2GW power plant has been approved under a Clean Air Act permit; it is not fully clear whether the permitted system is the same imported equipment previously reported in some accounts.
While the phased transition continues, the company also says it will outfit each mobile turbine with "advanced emission control technologies" to reduce air emissions during the drawdown. SpaceXAI frames the plan as an effort to balance uninterrupted operational needs at its Colossus centers with regulatory and community concerns about air quality.
Bottom line: The turbines will be removed in a controlled, phased process over roughly 12 months as the permitted 1.2GW plant is brought online, and interim emissions controls will be applied to the mobile units.
