Terafab, SpaceX and Tesla's planned Texas chip and AI campus, is 'not expected to use electricity from the grid' under its Grimes County tax abatement deal, though an analyst notes the site may still hold a grid connection.
A line in a Grimes County tax-abatement agreement is reframing how SpaceX and Tesla's Terafab campus will be powered. The agreement says the facilities "are expected to be powered by on-site power plant(s) and are not expected to use electricity from the grid," turning the planned Texas chip and AI site into a primary self-supply AI compute campus with the public grid demoted to backup.
SpaceX and Tesla unveiled an initial $16.8 billion investment in Terafab on Aug. 6, describing a 100-million-square-foot campus in Grimes County. Texas incentive filings describe a four-phase project with potential investment of $119 billion. The abatement also references "the battery storage project," putting on-site generation and storage at the center of the planned infrastructure.
Grimes County designated the SpaceX property as a reinvestment zone on June 3, listing a semiconductor plant, an AI facility, and a power plant. The deal would put SpaceX in charge of generation, reserves, voltage and frequency control, storage, and restoration, roles normally filled by the grid operator.
Neil Osnato of Persistence Analytics Group told Data Center Knowledge: "For a semiconductor/AI complex of the scale being contemplated here to plan for primary self-supply with essentially no routine grid electricity is much more unusual." The agreement does not say Terafab will be physically disconnected; a grid-connected site can still rely on onsite primary supply under normal conditions.
