SpaceX Plans $74 Billion in Sun Belt AI Campuses. Communities Face the Trade-Offs

Two enormous artificial intelligence projects proposed for Texas and Arizona are putting the Sun Belt’s appetite for major technology investment to a new test. SpaceX is pursuing supercomputing campuses whose combined projected spending exceeds $74 billion, but the questions now facing nearby communities extend beyond their price tags.

The company is planning a roughly $24 billion gas-fired power plant and computing campus in Starbase, Texas, and a separate project estimated at about $50 billion in Cochise County, Arizona. Both could bring construction work and long-term employment. Both also raise questions about land use, utilities and who ultimately benefits from projects that consume extraordinary amounts of energy.

A large Arizona proposal still needs approval

In southeastern Arizona, the proposed campus would occupy approximately 747 acres along U.S. Highway 191 near the Apache Generating Station. The plan includes up to nine computing buildings developed in four phases, with battery energy storage, electrical systems and cooling infrastructure.

The project has not secured its county land-use approval. The Cochise County hearing notice sets a Planning and Zoning Commission public hearing for December 9. The application seeks special authorization for the campus on land currently zoned rural.

The investment would be enormous even by the standards of the fast-growing data-center industry. SpaceX’s plans envision approximately 5,500 construction jobs and 1,000 permanent jobs in Arizona. Those are project expectations, not jobs already created.

SpaceX has said the proposed facility would use dry cooling rather than industrial groundwater and that arrangements with local electric cooperatives could benefit electricity customers. But those assurances will face public scrutiny: a petition opposing the project has collected thousands of signatures, and county officials have cautioned against treating applicant projections as independently established outcomes. Reuters detailed the project’s economic and environmental claims this week.

In Texas, boundaries and tax incentives matter

Near Brownsville, SpaceX is planning a gas-fired power plant and supercomputing operation on approximately 444 acres now within Starbase. That land had previously been removed from Brownsville’s jurisdiction after a negotiated arrangement involving $220 million for city water and wastewater improvements.

The subsequent jurisdictional changes matter. Brownsville adopted a temporary moratorium on data-center development, but the project land is no longer subject to Brownsville’s city rules. The Texas Tribune reported the sequence of de-annexation, annexation and the proposed development.

Starbase officials are expected to consider a property-tax abatement and economic development agreement at a December 9 public hearing. The size and duration of a possible tax break have not yet been established publicly. Nor have all details of the facility’s generating capacity and computing operations been released.

The Sun Belt’s next growth question

For years, Sun Belt governments have competed to attract major industrial and technology projects with the promise of jobs, construction spending and a larger tax base. Data centers change some of that calculation. They can require massive investment and extensive electrical infrastructure while employing comparatively fewer people once construction is complete.

SpaceX’s proposed campuses bring that trade-off into unusually sharp focus. In Arizona, a rural county must weigh the prospects of economic development against the consequences of a new industrial use on hundreds of acres. In Texas, a planned power plant, shifting municipal boundaries and a potential tax agreement are drawing attention to who makes the decisions.

Neither project’s headline investment figure guarantees the promised benefits. The lasting story will be written in the details: how the facilities obtain electricity and water, how local governments structure tax agreements, and what communities receive in return.
