xAI Faces Lawsuit Over Unpermitted Gas Turbines at Mississippi Data Center

Unpermitted Power Generation

Elon Musk's artificial intelligence company, xAI, is facing a lawsuit over the operation of nearly 50 natural gas turbines at its Colossus 2 data center in Southaven, Mississippi. The legal action centers on the company's use of "mobile" gas turbines to function as permanent power plants.

According to reports, xAI has more than doubled the number of unchecked natural gas generators at the Southaven facility since the company first arrived in Mississippi last summer. State officials are currently evaluating the status of these unpermitted turbines.

Expansion Despite Legal Action

Internal emails reviewed by Wired indicate that xAI has added 19 new natural gas turbines to the Southaven campus over the past two months. This expansion occurred while the company was already embroiled in a lawsuit regarding its power infrastructure,.

These additions bring the total number of turbines at the site to nearly 50. The company has previously faced scrutiny for similar operations at its South Memphis data center, where it was reported that the company operated methane gas turbines without necessary permits.

Environmental and Regulatory Concerns

Critics and legal experts allege that the company's power generation methods may be in violation of the Clean Air Act. Specifically, at the South Memphis site, it was noted that 35 gas turbines required a major source permit under the Clean Air Act due to their high NOx emissions.

In Memphis, the turbines—which possess enough capacity to power 280,000 homes—operate without emission controls. This has drawn significant backlash in an area that already leads the state of Tennessee in asthma rates.

Regional Context

In 2024, xAI constructed what was described as the world's largest AI data center in South Memphis. While the project was initially presented with promises of regional development and job creation, it has since become a point of contention regarding environmental impact and regulatory compliance.

State officials in Mississippi are now reviewing the Southaven facility to determine if the expanded fleet of turbines requires similar permits and emission controls as those mandated for the Memphis operations.
