SpaceX’s Terafab Facility Will Use On-Site Natural Gas for Power Due to Precision Requirements
SpaceX is planning a massive facility, called Terafab, in Grimes County, Texas, which will be entirely powered by on-site natural gas turbines and battery storage. The company aims not to draw electricity from the grid due to concerns over reliability and precision needed for semiconductor manufacturing. Analysts suggest that this decision stems from the high sensitivity of chip fabrication equipment to power fluctuations. Despite Tesla's expertise in solar energy, Terafab will rely on gas rather than solar because inverters used with solar can introduce harmonic distortion into the electrical signal—something critical when maintaining stable voltage levels for semiconductor production. Gas turbines offer a more consistent and reliable source of clean AC power without requiring conversion from DC. The site was previously home to a coal-fired plant, providing existing infrastructure that could aid in meeting SpaceX’s ambitious timeline to begin operations by late 2027.
