SpaceX to build onsite natural gas power plants and battery storage for Terafab semiconductor and AI campus in Texas

Type: Development · Technology: Gas, Storage, Data Center · Country: United States · Announced: 2026-08-05

SpaceX and Tesla announced a $16.8 billion initial investment for Terafab, a 100-million-square-foot semiconductor and advanced-computing campus in Grimes County, Texas. The project includes plans for onsite natural gas-fired power plants and large battery arrays to supply electricity, bypassing reliance on the grid as outlined in a fully executed tax-abatement agreement with the county. The agreement specifies that facilities will be powered by onsite generation and batteries, with no routine grid electricity expected, though a physical connection may remain for startup power or emergencies. SpaceX's lead developer Riley Trettel confirmed the natural gas and battery plans during a county commissioners meeting. The campus will also include a semiconductor manufacturing plant, an AI facility, and a power plant, with a potential total investment of up to $119 billion across four phases.
