SpaceX confirms internal foundry to accelerate gas turbine production

SpaceX has confirmed the construction of a secret foundry in Bastrop, Texas, designed to manufacture critical components for natural gas turbines. Elon Musk stated on social media that the facility aims to address a significant bottleneck in the production of gas turbines, which are increasingly required to support the energy demands of artificial intelligence infrastructure. The move is intended to accelerate the deployment of gas turbine capacity by up to 18 months, a timeframe Musk described as a profound game-changer for the sector.

The announcement follows a report by The Information, which cited job listings and due diligence findings indicating that SpaceX had acquired approximately 830 acres near its existing Starlink factory in Bastrop between March and June. The report highlighted explicit references to a blades and vanes foundry within the company’s recruitment materials. Musk clarified that both SpaceX and Tesla are rapidly expanding solar production capacity, with each targeting 100 gigawatts per year. However, he noted that natural gas remains necessary to supplement and bootstrap solar power for several years. The primary limiting factor for gas turbine production, according to Musk, is the casting of blades and vanes, a process SpaceX intends to bring in-house to overcome supply constraints.

The urgency of this infrastructure build-out is driven by the physical power grid constraints facing the AI industry. While GPU shortages persist, with lead times for Nvidia’s Blackwell chips remaining in the several-months range, a second constraint has emerged in the form of electricity availability. The International Energy Agency projects that global data center electricity use will roughly double by 2030. In response, gas turbine manufacturer GE Vernova has reported that it is essentially sold out of production capacity through 2030, largely due to demand from AI infrastructure. This scarcity has led major technology companies, including Amazon, Google, Meta, OpenAI, and Microsoft, to adopt a strategy of building private gas-fired plants adjacent to data centers rather than waiting for grid expansion.

The technical challenge of manufacturing turbine blades is substantial. The blades in the hottest section of a gas turbine operate at temperatures between 3,000 and 3,600 degrees Fahrenheit, which is approximately 800 degrees hotter than the melting point of the metal alloy used. This is made possible by internal cooling channels, thermal-barrier coatings, and a specific casting method that requires each blade to be grown as a single, unbroken crystal inside a vacuum furnace. This process avoids the microscopic seams that cause ordinary cast metal to crack under stress. Currently, only four companies worldwide have mastered this casting process at an industrial scale, and all are reportedly tapped out. The blades used in power-plant turbines are considerably larger than those in jet engines, making defect-free production at scale even more difficult.

If SpaceX successfully implements this manufacturing capability, it would possess a strategic advantage in the AI infrastructure market. This would reduce dependence on a small oligopoly of suppliers, a capability that is difficult for well-funded competitors without manufacturing expertise to replicate quickly. However, the accelerated deployment of gas turbines raises significant environmental and public health concerns. Turbines emit smog-forming compounds and hazardous chemicals, including formaldehyde, which are linked to asthma, respiratory disease, and certain cancers.

In Memphis, where SpaceX has operated gas turbines to power its Colossus data centers since 2024, the NAACP has accused the company of operating without required permits or pollution controls. University of Memphis researchers noted in a limited analysis that air pollution in the area had grown slightly worse due to the data center. Similar disputes are occurring in Virginia’s Data Center Alley, where a study commissioned by the Piedmont Environmental Council found that emissions from a single facility’s eight full-time gas turbines could affect more than 2.5 million people across multiple counties. The study estimated that these emissions could cause between 3.4 and 6.5 additional premature deaths annually, resulting in health-related damages valued between $53 million and $99 million.
