SpaceX to Remove Unpermitted xAI Gas Turbines in Mississippi by July 2027

SpaceX announced on Thursday that it plans to remove unpermitted gas turbines currently supplying power to xAI data centers near Memphis as it transitions to a permanent 1.2 gigawatt natural gas power plant. However, the existing turbines will remain operational and will not be fully removed until July 2027.

What Happened

SpaceX, which acquired xAI in February, is operating 69 temporary gas turbines to supply power to its Colossus data centers. Located in Mississippi just south of Memphis, Tennessee, many of these turbines have been running for months. SpaceX contends that operating the existing units without environmental permits is permissible because they remain mounted on their transport trailers. Federal regulations, however, require permits for turbines of this size and operational scope, regardless of whether they sit on trailers. The NAACP and the Southern Environmental Law Center have filed a lawsuit against xAI over the unpermitted operations.

Key Highlights

  • SpaceX will fully remove the 69 unpermitted turbines by July 2027 as it builds a permanent power facility.
  • The current turbine setup has the potential to produce over 2,000 tons of smog-forming nitrogen oxides (NOx) per year in an area recognized as one of the most polluted in the United States.
  • The U.S. Department of Justice intervened in the NAACP lawsuit last month on behalf of SpaceX, calling the unpermitted turbines a matter of national, economic, and energy security.
  • State permit filings in Mississippi show the new permanent 1.2 gigawatt facility will feature 41 gas turbines with outputs ranging from 16.48 megawatts to 50 megawatts.
  • In its IPO documentation, SpaceX disclosed plans to purchase $2.8 billion in gas turbines for its data centers over the next three years.
  • Elon Musk purchased temporary power firm APR Energy earlier this year, but its turbines appear distinct from those listed for the new permanent facility, suggesting they may be intended for a different, unannounced project.

Why This Matters

The situation highlights environmental concerns surrounding massive energy demands for data processing facilities in heavily polluted regions. While local and environmental groups have sued over emissions and permit requirements, federal authorities have supported the temporary operations by citing broader national and economic security interests.

What to Watch Next

Subsequent developments include the progression of the NAACP lawsuit, state permitting processes, and the construction timeline for the permanent 41-turbine plant scheduled to replace the current setup by July 2027.

Frequently Asked Questions

Why does SpaceX claim the existing turbines do not need permits?

SpaceX claims the turbines are exempt from permits because they remain on the trailers used to deliver them. However, federal rules require permits based on equipment size and usage regardless of trailer placement.

When will the current turbines be taken down?

SpaceX expects to complete the removal of all 69 temporary turbines by July 2027.

What will replace the current power setup?

SpaceX is constructing a permanent 1.2 gigawatt natural gas power plant comprising 41 turbines ranging from 16.48 megawatts to 50 megawatts.
