SpaceX will build natural gas power plants to supply electricity to the Terafab semiconductor factory it plans to construct in Grimes County, Texas, roughly 45 miles northwest of downtown Houston, according to a Bloomberg report TechCrunch.

Riley Trettel, who leads energy and data center development for SpaceX, said in a public meeting that SpaceX will be "bringing our own power" for the Terafab project, which will also include "very large battery arrays" TechCrunch. The on-site power plant will consist of 41 gas turbines ranging in size from 16.48 megawatts to 50 megawatts TechCrunch.

The Terafab plant is planned as a 100-million-square-foot vertically integrated facility that will manufacture, package, and test advanced logic and memory chips under one roof Reuters. SpaceX and Tesla will initially spend $16.8 billion on the plant, though SpaceX had previously estimated the cost at $55 billion Reuters. Texas Governor Greg Abbott announced the project as bringing more than $16.8 billion in investment and 3,000 jobs to the state Governor's Office.

Grimes County granted SpaceX a 100% tax abatement for Terafab in exchange for SpaceX spending at least $5 billion by 2030 and creating at least 1,800 full-time jobs by 2035 TechCrunch. The state of Texas is providing $30 million in incentives TechCrunch. The chips produced at Terafab are intended for data centers that will be operated by SpaceX and its xAI subsidiary TechCrunch.

The decision to self-generate power rather than rely on grid supply places SpaceX within a broader trend. Texas has charted out more than 70 gigawatts of capacity for "bring your own power" data centers TechCrunch. Data center demand has already driven a 66% surge in natural gas power plant costs TechCrunch. The 41-turbine configuration SpaceX plans is consistent with a strategy of deploying gas-fired generation at scale to avoid interconnection delays and grid capacity constraints that have become acute in regions with heavy data center buildout.

The choice of natural gas turbines over solar or other renewable generation is notable given SpaceX's corporate adjacency to Tesla, whose solar and battery storage products would seem a natural fit for on-site power. The economics and dispatchability of gas-fired generation, particularly for a semiconductor fab with continuous, high-baseline power requirements, likely make it the pragmatic option. Semiconductor manufacturing demands uninterrupted, high-quality power at massive scale; intermittent generation paired with battery storage can serve as a supplement, but the primary load for a fab of this magnitude calls for firm capacity.

The turbine specification also carries regulatory implications. SpaceX's xAI subsidiary has already encountered permitting friction in Texas over gas turbines deployed for data center operations. In late July, reporting indicated that SpaceX would not remove all of xAI's unpermitted turbines for another year TechCrunch. That history invites scrutiny of whether the Terafab power infrastructure will proceed through a cleaner permitting path or encounter similar friction as it scales to 41 turbines.

SpaceX has applied to list its Class A common stock on Nasdaq and on Nasdaq Texas under the ticker symbol "SPCX," according to prospectus documents filed with regulators SpaceX Prospectus. A public listing would give SpaceX access to capital markets at a moment when it is committing to one of the largest semiconductor manufacturing investments in recent memory.

The scale of Terafab is difficult to overstate. A 100-million-square-foot facility would rank among the largest single-building manufacturing complexes in any industry. The vertical integration model, covering logic and memory fabrication, packaging, and testing under one roof, mirrors the strategy pursued by leading-edge foundries that have moved toward co-locating these stages to reduce cycle times and yield loss from transit. Whether SpaceX and Tesla can execute on semiconductor manufacturing at this scale is an open question, and one that the industry will watch closely given that neither company has prior experience operating a commercial fab.

The power strategy may ultimately be the most replicable element of the plan. If the "bring your own power" model proves workable at Terafab's scale, it could establish a template for other hyperscale operators facing the same grid interconnection bottlenecks. The trade-off, of course, is emissions. Forty-one gas turbines running continuously to feed a semiconductor fab and downstream data centers will produce a substantial carbon footprint, and that calculation will figure into any honest assessment of the project's environmental cost.
