Mississippi regulators have granted a permanent air permit to Elon Musk’s xAI for its 41-turbine methane power plant in Southaven. The decision by the MDEQ allows the company to support its Colossus 2 and Macrohardrr datacenters with an on-site generation facility. This move has been widely condemned by local residents who have fought against the project for months.
The turbines provide 1.2 gigawatts of power, enough to fuel the world’s largest single-site AI training installation. This infrastructure is essential for training xAI’s Grok models, which require massive amounts of compute and electricity. By generating power on-site, xAI can maintain its competitive edge in the global artificial intelligence market.
The NAACP and SELC have called the permitting process a “mockery of justice,” noting that the decisive meeting was held on a state election day. Residents have reported persistent noise and air quality issues since the facility first began “temporary” operations last year. The NAACP has filed a notice of intent to sue, alleging that xAI is violating the federal Clean Air Act.
The environmental impact of the turbines is a major concern, as they release hazardous levels of formaldehyde and nitrogen oxide. These pollutants are known to cause chronic respiratory problems and increase the risk of heart attacks. Critics argue that the state is allowing a “dirty facility” to operate in a residential area without adequate environmental oversight.
Despite the controversy, xAI’s $20 billion investment is expected to transform Mississippi into a global hub for AI innovation. Governor Tate Reeves has hailed the project as the largest private investment in state history. The ongoing conflict between Musk’s ambitious timeline and community environmental protections is set to reach the federal courts soon.
