SpaceX’s Terafab: Powering the Future with Natural Gas, Not Tesla Solar Energy
This week, SpaceX announced plans to construct natural gas power plants to provide energy for the Terafab semiconductor facility it intends to build in Texas, as reported by Bloomberg.
Riley Trettel, who oversees energy and data center projects at SpaceX, shared during a public meeting on Wednesday that the company will be “bringing our own power” for this initiative, which will also feature “very large battery arrays.”
Interestingly, Bloomberg’s report, along with other SpaceX communications regarding Terafab, did not mention any deployment of solar energy for the facility. Tesla, another of Elon Musk’s ventures, is a partner in the project and specializes in solar energy.
Despite Musk’s ongoing investments in solar technology, he has recently favored natural gas. The xAI data centers in Memphis primarily rely on this fossil fuel. Musk has also acquired a firm focused on natural gas power plants and SpaceX plans to invest $2.8 billion in gas turbines over the next three years.
The Terafab site will be situated in Grimes County, roughly 45 miles northwest of Houston’s city center. SpaceX, which recently went public and raised $87.5 billion, has secured a 100% tax exemption from the county, committing to invest a minimum of $5 billion by 2030 and generate at least 1,800 full-time positions by 2035. Additionally, Texas is offering incentives amounting to $30 million.
The projected cost for the initial phase of the semiconductor manufacturing facility is estimated at $16.8 billion, a reduction from prior estimates of $55 billion. The fab will produce chips for data centers operated by SpaceX and its xAI subsidiary.
The surge in demand for AI data centers has triggered an influx of proposals for new natural gas power plants throughout the industry, which has increased costs for such plants by 66%. Tech giants Google, Meta, and Microsoft have recently announced significant projects in this sector.
Texas has emerged as a central hub for these “bring your own power” data center initiatives, with over 70 gigawatts of power capacity already mapped out.
While these projects aim to expedite development and alleviate concerns over rising electricity expenses for consumers, the use of natural gas turbines can lead to considerable pollution. Notably, SpaceX’s subsidiary xAI is currently facing legal challenges due to the operation of unpermitted natural gas turbines in one of the nation’s most polluted areas.
