In a major win for Elon Musk’s xAI, Mississippi state regulators have approved the operation of 41 methane gas turbines at the Colossus 2 datacenter. This authorization effectively doubles the energy capacity of the site, which is used to power the company’s AI supercomputers. These massive machines are responsible for training and running the Grok AI model. The approval comes from the Mississippi Department of Environmental Quality, despite months of vocal protests from Southaven residents.
The rapid growth of xAI in the region has been characterized by a “build fast” mentality that has often bypassed traditional planning phases. The company’s first major datacenter in Memphis already uses 15 gas generators, and a third site, Macrohardrr, is currently in development. This cluster of facilities is designed to house some of the world’s most powerful computing hardware. However, this high-speed development has led to significant friction with those living in the shadow of the massive datacenters.
Community leaders and the NAACP have slammed the state’s decision, claiming that the voices of those most affected were silenced. At a recent hearing, no local residents spoke in support of the permit, with many citing noise and health fears. The NAACP has already filed a lawsuit against xAI, alleging that the company’s pollution levels are hazardous to the community. Activists argue that the MDEQ rushed the approval to cater to the billionaire’s business interests.
The primary environmental concern involves the emission of hazardous chemicals such as nitrogen oxide and formaldehyde. These pollutants are known to cause a range of illnesses, from asthma and respiratory issues to heart attacks. The American Lung Association has already given the region an “F” for its air quality, making the addition of 41 turbines a serious concern for health advocates. If fully operational, the site will be among the largest fossil fuel power plants in the state.
The situation in Mississippi serves as a case study for the tensions between the tech industry and environmental justice. While xAI now has the permits it needs to expand its computing power, the social and legal backlash remains a significant obstacle. The results of the NAACP’s legal challenge will be a crucial indicator of the project’s long-term viability. For now, the expansion of Colossus 2 represents a major step forward for Musk’s AI ambitions, regardless of the local cost.
