#Why Does the AI Boom Rely on Electricity?
The rapid expansion of artificial intelligence technology demands significant electricity resources, often urgently. In response to extensive utility interconnection delays, data center operators are opting to build their own natural gas power plants. This approach is typically executed with minimal permitting requirements and limited public scrutiny.
Evidence from Cleanview indicates that at least 57 off-grid natural gas plants have been proposed or constructed specifically to supply power to data centers across the United States. These projects together have a substantial capacity of about 73 gigawatts, sufficient to light up tens of millions of homes.
#What is the Colossus Problem?
The situation surrounding xAI’s Colossus facilities in Mississippi exemplifies the tension in this development. The first Colossus site began operations in June 2024, utilizing up to 35 gas turbines initially without the necessary permits. Only after legal challenges were initial permits partially secured.
The second facility, Colossus 2, located in Southaven, Mississippi, houses 27 gas turbines with the capacity to generate up to 495 megawatts, also installed without initial permits. The emissions forecast from the Colossus 2 site is concerning, projecting over 1,700 tons of nitrogen oxides (NOx) annually, as well as other harmful pollutants that can significantly impact local air quality.
In April 2026, a coalition including the Southern Environmental Law Center, Earthjustice, and the NAACP initiated a lawsuit aimed at halting xAI’s Mississippi operations. Their case focuses on health risks posed to surrounding communities due to the facility’s operation without appropriate air quality permits.
#Is This a National Issue?
Mississippi is not an isolated case. Across the nation, similar projects have sprung up. In Texas, the GW Ranch project stands out, while Virginia is home to the Vantage project. Together, these various gas-fired projects associated with data centers are poised to emit more than 129 million tons of greenhouse gases each year.
Unlike conventional emergency diesel generators, these gas facilities operate continuously. This constant operation raises significant environmental concerns, particularly in communities already facing air quality issues. Residents near these developments often only learn of their construction after the project has commenced, leaving little room for public input or concern.
