Musk's xAI has increased Tennessee gas turbines, without permits, say community groups

According to a letter sent by community groups to the county health department, Elon Musk's xAI nearly doubled the number of gas turbines in its Tennessee data center. This is more than the previously known numbers and the number that the company had submitted for permits.

Southern Environmental Law Center, along with local groups, has called on the Health Department to stop operating all turbines until the company adheres to the Clean Air Act as well as local protections.

The Environmental Protection Agency, Shelby County Health Department, and xAI have not responded to our requests for comment.

The Southern Environmental Law Center stated that "the dozens of turbines outside the datacenter are likely to make xAI Memphis' largest industrial source for the smog-forming NOx pollutant."

xAI's data center turbine expansion and the resulting emissions are requiring a "major sources permit", but the company is operating the equipment without regulatory authorization.

As clean energy deployments struggle to meet the demand, the massive increase in power consumption in AI-supporting US data centers is driving a rise in fossil fuel usage.

Last year, Musk, a billionaire, had called the Tennessee datacenter, which powers Grok, the chatbot of his firm, "the world's most powerful AI training cluster".

The environmental law firm said xAI’s 35 gas-turbines have a combined capacity of 422, MW. This is comparable to Tennessee Valley Authority’s Brownsville gas-powered power plant with a 425 MW capacity.

In August, it was reported that xAI’s Memphis data centre had installed 20 gas turbines. The combined power of these gas turbines is about 100 MW.

The Greater Memphis Chamber announced in December that xAI plans to expand its Memphis Supercomputer to accommodate at least 1 million graphics processing units.

The AI firm acquired Musk's X at the end of March in a deal valued at $33 billion. (Reporting and editing by Devika Syamanath in Bengaluru)
