Musk Leans on Natural Gas Turbines to Power SpaceX AI Data Centers

Elon Musk is going all-in on natural gas to feed SpaceX's artificial intelligence build-out, with turbines being installed on-site to bypass multi-year grid interconnect queues. It is a sharp pivot from his prior climate branding, and it puts SpaceX at the center of the AI power trade.

The Bring Your Own Power play

SpaceX is building AI data centers and a $16.8 billion chip-manufacturing facility in Texas, and because connecting projects of this scale to the electrical grid can take years, the company is installing its own natural-gas turbines and power plants, marking a significant shift from Musk's earlier emphasis on technologies designed to replace fossil fuels.

Musk has embraced a “Bring Your Own Power” strategy because natural gas can provide 24/7 electricity much faster than traditional grid connections. Translation: speed to power is the new moat in AI infrastructure.

The numbers behind the build-out

SpaceX's data-center power capacity could increase from roughly 2 gigawatts to around 10 gigawatts, or potentially 15 gigawatts, by the end of 2027, which would make it the largest data-center operator in the United States.

The SpaceX IPO filing revealed plans to spend more than $2.8 billion on natural gas turbines over three years to power AI data center operations, with roughly $2 billion earmarked for mobile gas turbines and a separate $805 million in turbine orders already placed and deliveries running through 2029.

Musk bought the turbine supplier too

Musk acquired mobile gas turbine company APR Energy, based in Jacksonville, Florida, which owns one of the world's largest mobile gas turbine fleets with more than a gigawatt of capacity, modular units that can be brought online in as little as 30 days behind-the-meter or grid-tied.

The billionaire now owns both a fleet of turbines and the AI data centers that demand them. Vertical integration on the power stack, with the same "own the supply chain" playbook Tesla ran on batteries.

Regulatory and revenue backdrop

Musk's xAI ran up to 69 unpermitted turbines near Memphis, drawing EPA violations and an NAACP lawsuit over 2,000 annual tons of nitrogen oxide. SpaceX said it will remove the unpermitted turbines powering its xAI data centers near Memphis as it transitions to a permanent 1.2 gigawatt natural gas power plant that will consist of 41 gas turbines ranging in size from 16.48 megawatts to 50 megawatts.

Anthropic pays $1.25 billion monthly to rent xAI data center space, helping drive 247% year-over-year AI revenue growth for SpaceX. The compute-for-rent model is what makes the turbine spend pencil out.

Options market and stocks to watch

SPCX: Watch for reaction as the newly public SpaceX carries the full weight of the $2.8B turbine capex and the AI revenue ramp.

NVDA: Watch for follow-through given the next phase of expansion at Colossus 2 will bring online at least 220,000 additional GB300 processors and over 400 additional megawatts of compute power.

GE and ETN: Watch for demand tailwinds across gas turbine OEMs and electrical infrastructure names as hyperscalers copy the behind-the-meter model.

TSLA: Watch for read-throughs as Tesla Megapack orders continue to feed the same xAI compute footprint, blurring the line between the Musk entities. See other news for related Musk-complex updates.
