Elon Musk’s artificial intelligence company xAI has installed 59 natural gas turbines for its Colossus 2 data center project in Tennessee without securing federal clean air permits, according to communications between regulators and xAI representatives.
Potential emissions from the turbines are far beyond the threshold that would require a federal permit, and would be released near predominantly Black communities already estimated to be suffering disproportionately high rates of lung disease, according to a Reuters analysis based on government data and information in the correspondence with regulators.
The findings, which have not been previously reported, reflect how exploding electricity demand from AI data centers is driving companies to build off-grid power plants at a pace outstripping environmental oversight, with potentially big risks to public health.
The number of unpermitted turbines identified by Reuters is about double what xAI has publicly acknowledged. The company previously said it was running 27 unpermitted turbines for Colossus 2 as of January and has argued the permits are not required. At least 57 of the 59 turbines are located in Mississippi, just over the state line from Tennessee where the data center is located.
The xAI turbines are among scores of off-grid power plants for data centers proposed or under construction around the country. Local authorities often fast-track approvals in just weeks or months, without the years of environmental studies and public hearings typically required for such power generation projects that connect to the grid, Reuters has reported.
