As pollution concerns mount in Memphis, the AI giant proposes a green energy patch for its massive “Colossus” data center.
- A Drop in the Bucket: xAI plans to build an 88-acre solar farm next to its Memphis supercomputer, but the estimated 30 megawatts of power it will generate covers only about 10% of the facility’s immense energy appetite.
- Pollution & Public Health Crisis: The company faces fierce backlash for operating unpermitted gas turbines that have reportedly spiked nitrogen dioxide levels by 79% in the historic Black community of Boxtown, leading to increased respiratory issues among residents.
- Regulatory & Financial Paradox: While xAI relies on temporary gas turbines in both Tennessee and Mississippi to bypass strict pollution tracking, its solar partner recently secured a massive $439 million federal award—a rarity in the current political climate—to help fund clean energy infrastructure.
In the race to dominate the future of artificial intelligence, the physical cost of digital progress is becoming increasingly visible in the American South. Elon Musk’s artificial intelligence startup, xAI, recently informed city and county planners in Memphis of its intention to construct a solar farm adjacent to its “Colossus” data center. While the move signals a shift toward renewable energy for one of the world’s largest AI training facilities, the project highlights the stark disparity between the industry’s insatiable demand for power and the environmental reality on the ground.

The proposed solar project is slated to occupy 88 acres to the west and south of the existing data center, utilizing land near a 136-acre vacant lot owned by the same developer. Despite the significant footprint, the physics of solar energy reveals the sheer scale of Colossus’s consumption. Experts estimate the new farm will produce approximately 30 megawatts of electricity—a figure that represents a mere 10% of the data center’s estimated total power usage. This gap underscores the massive energy hurdles facing the AI sector, where the computational power required to train advanced models demands electricity loads comparable to entire cities.
However, the pivot to solar comes against a backdrop of intense regulatory scrutiny and community outrage. The Southern Environmental Law Center (SELC), working in conjunction with the NAACP, has accused xAI of operating over 400 megawatts of natural gas turbines without the necessary permits. According to the SELC, the company has been running at least 35 turbines capable of spewing more than 2,000 tons of nitrogen oxide (NOx) annually. These emissions are a primary contributor to smog and can cause severe respiratory distress, a reality that residents of the nearby Boxtown neighborhood say they are already living.
Boxtown, a predominantly Black community with a rich history, has found itself on the frontlines of this environmental battle. Researchers from the University of Tennessee, Knoxville, discovered that peak nitrogen dioxide concentration levels skyrocketed by 79% in the areas immediately surrounding the data center after xAI commenced operations. The human cost of this statistic is being felt daily; community activists have reported a noticeable uptick in asthma attacks and other respiratory issues since the facility opened its doors.

xAI has publicly stated that the gas turbines are a stopgap measure intended for use only until the company can secure sufficient power from the grid. Yet, local officials recently granted the company a permit to continue operating 15 of these turbines through January 2027, extending the timeline of fossil fuel reliance. Furthermore, the company’s expansion isn’t limited to Tennessee. In Mississippi, xAI has installed 59 gas turbines to power its “Colossus 2” data center. By classifying 18 of these units as “temporary,” the company effectively sidesteps standard regulatory tracking of their pollution output.
Despite the reliance on fossil fuels, there are movements toward a cleaner infrastructure. In September, xAI announced a separate initiative to build a 100-megawatt solar farm nearby, paired with 100 megawatts of grid-scale batteries to ensure a 24/7 electricity supply. While xAI has not disclosed the total cost, the financial backing for the solar infrastructure is substantial. Seven States Power Corporation, the developer behind the solar farm, was awarded $439 million from the U.S. Department of Agriculture, including a $414 million interest-free loan. This federal support is particularly notable given the current political landscape, where the Environmental Protection Agency and the Department of Energy under the Trump administration have canceled numerous clean energy grants and loans.
As xAI continues to expand its footprint across the South, the tension between technological ambition and environmental stewardship remains unresolved. The new solar farm represents a step forward, but for the residents of Boxtown breathing the exhaust of the “temporary” turbines, the transition to clean energy cannot come fast enough.
