SpaceX Plans to Power $16.8B Terafab Without the Grid

A major semiconductor and artificial intelligence campus planned for Texas will power itself using onsite natural gas power plants and battery storage instead of relying on the electrical grid. The facility is designed to operate like a private utility rather than a conventional industrial customer, with multiple generating units, reserve capacity, and battery systems to maintain power quality and continuity needed for semiconductor manufacturing. This approach is unusual for a facility of this scale and shifts the responsibility for reliability from the public grid to the campus itself, though a grid connection may still exist for startup power or emergency situations. The model represents a different approach to powering very large computing loads and creates new questions about how grid planners should account for massive industrial facilities that may have minimal routine demand on the public electricity system.
