ANDERSON, Texas — A proposed SpaceX semiconductor and advanced computing facility just outside of the Houston metro area in Grimes County is moving forward after county commissioners approved a tax incentive package tied to what could become one of the largest industrial investments in Texas history.
The Grimes County Commissioners Court voted 4-1 this week to approve a reinvestment zone and a 100% property tax abatement for Space Exploration Technologies Corp., better known as SpaceX. The proposed project, referred to in public discussion and media reports as “Terafab,” would be located near the Gibbons Creek Reservoir area and surrounding properties.
According to the county’s public hearing notice, SpaceX proposed a multi-phase, vertically integrated semiconductor manufacturing and advanced computing fabrication facility. The notice listed the estimated capital investment for initial phases at $55 billion, with a possible total investment of $119 billion if additional phases are built.
Supporters have described the proposal as a potentially transformative economic development opportunity for Grimes County, a largely rural county between Houston and Bryan-College Station. They say the project could bring major investment, jobs, technical workforce development and a larger tax base to the region.
But the approval has also raised strong objections from residents who say the process moved too quickly and without enough public information. At the commissioners court meeting, many speakers expressed concern about water use, power demand, environmental impact, light pollution, traffic, wildlife, and the effect of a large industrial project on the county’s rural character.
Commissioner David Tullos, who cast the only vote against the measures, questioned the size and clarity of the proposed reinvestment zone and said SpaceX had not provided enough direct communication with county officials or residents. Local reports said Tullos urged the court to delay action so commissioners could better evaluate the agreement and answer residents’ questions.
The tax abatement was one of the most debated parts of the agreement. Critics argued that a company associated with Elon Musk should not receive a full property tax abatement from a small county, especially before residents have more details about infrastructure and environmental protections. Supporters countered that without incentives, Grimes County could lose the project — and the long-term economic activity it may generate — to another location.
Reuters reported that the agreement includes a payment in lieu of taxes structure, with SpaceX expected to make annual payments to the county even while receiving the tax abatement. Musk defended the deal publicly, saying the company’s payments would still increase county revenue.
The project also comes as Texas continues to position itself as a major center for semiconductor manufacturing, advanced computing and technology infrastructure. Major chip and technology-related investments have already been announced or built in other parts of the state, including Central Texas and North Texas. SpaceX’s proposal would expand that activity into a rural county where residents say the scale of the development could permanently change the area.
The public hearing notice identified Space Exploration Technologies Corp. as the applicant and described the project as a next-generation domestic semiconductor manufacturing investment. The facility would be tied to advanced computing and semiconductor production, sectors that have become increasingly important to artificial intelligence, autonomous systems, electric vehicles, space technology and national technology competition.
For Grimes County, the question is not only whether the project could bring money and jobs, but whether local government can manage the pace and scale of the development. Residents who spoke against the deal said they wanted enforceable protections, clearer maps, environmental safeguards and a fuller explanation of what the county would be giving up in exchange for the promised investment.
The commissioners’ approval does not eliminate those questions. Instead, it begins the next phase of scrutiny over how the agreement will be implemented, what obligations SpaceX will have, how the project will affect surrounding landowners, and whether the economic benefits promised to Grimes County will outweigh the concerns raised by residents.
For now, county leaders have chosen to pursue the project. Many residents, however, say they will continue pressing for transparency, accountability and protections before the rural landscape around Gibbons Creek Reservoir is reshaped by one of the largest proposed technology developments in Texas.
