xAI, the SpaceX-owned AI firm led by Elon Musk, is running dozens of gas-powered turbines at its Mississippi data center without proper permits. The setup is built to meet the high energy demands of large-scale computing and AI workloads.

Local groups have pushed back over air quality and health risks, and legal action is now underway. The situation puts a spotlight on the growing tension between AI expansion, energy use, and environmental accountability.
xAI Expands Power for AI Infrastructure With Unregulated Turbines
xAI operates its Colossus 2 data center in Southaven, Mississippi, to run its AI systems, including its chatbot Grok. The site uses natural gas turbines to handle the heavy computing demand of large-scale AI training and processing.
There are now 46 turbines at the site, up from just 18 when xAI first arrived last year. Only 15 of those turbines have proper permits. The rest have been added under a state classification that has drawn sharp legal and public scrutiny.
Mississippi classifies the turbines as “mobile” because they are attached to flatbed trailers, which allows xAI to run them without an air permit for up to a year. Critics argue this is a loophole that lets the company avoid the kind of oversight that would normally apply to a facility of this size.
Lawyers from the Southern Environmental Law Center argue that Mississippi is misreading the federal Clean Air Act by allowing xAI to bypass the permit process. The law defines a stationary source as one that is “not self-propelled or intended to be propelled while performing its function,” but adds that it “may be mounted on a vehicle for portability.”
They said that language means the turbines should be treated as stationary and subject to full permit laws.
xAI Environmental and Regulatory Pressure Grows
Local groups have also raised concerns about air quality near xAI’s data center. The Memphis area is already failing to meet national smog standards and was recently named an asthma capital.
Notably, xAI’s turbines have the potential to emit more than 1,700 tons of nitrogen oxides per year. This has led to stronger scrutiny of how AI systems use energy.
The NAACP, represented by the Southern Environmental Law Center and Earthjustice, has also filed a federal lawsuit against xAI. The complaint asks the court to stop xAI from operating the turbines. They have also requested that the court offset any public health damage and fine the AI firm up to $124,426 for each day it breaks the law. The NAACP has further asked for an injunction to halt operations while the case proceeds.
Meanwhile, AI growth is driving higher power demand across data centers. In turn, many facilities now rely on large energy systems to stay online. Because of this, regulators are reviewing the environmental impact of the expansion.
