TL;DR
SpaceX announced plans for two AI computing campuses, in Texas and Arizona, with a combined planned investment of more than $74 billion. The projects differ in how they would obtain power and manage cooling, and both face local review; several details, including Texas facility water use and Arizona power approvals, remain unresolved.
SpaceX said November 12 it is advancing two AI supercomputing campus projects in Starbase, Texas, and Cochise County, Arizona, with more than $74 billion in planned investment. The proposals would require substantial energy and local approvals, while key questions remain about the Texas facility’s water needs, tax incentives and the Arizona project’s electricity arrangements.
In Texas, SpaceX says it plans to invest more than $24 billion in computing infrastructure on an approximately 444-acre site near the Port of Brownsville. A Starbase city notice describes the initial capital investment as about $24 billion, with possible later expansions, and identifies a gas-fired power plant as part of the project. SpaceX says the facility will generate its own electricity rather than draw from the public grid. The city notice does not state the plant’s capacity.
Local outlet The 956 Report, citing an air registration filed with the Texas Commission on Environmental Quality, reported that an initial temporary setup would use 35 natural-gas turbines totaling about 748 megawatts, later replaced by eight larger turbines totaling about 708 megawatts. Those figures are reported by the outlet, rather than specified in the city notice or SpaceX announcement. SpaceX says the Texas project would support training AI systems and research in areas including medical research, emergency response, manufacturing and national security. It projects more than 3,000 construction jobs and over 500 permanent positions.
The Arizona proposal is described by SpaceX as a roughly $50 billion campus on about 747 acres near Cochise. A county application filed by Tombstone Resources L.L.C. outlines as many as nine computing buildings, each about 493,000 square feet, built in four phases. The application estimates power demand of about 1,500 megawatts in the first phase and approximately 6 gigawatts at full build-out, alongside a 24-gigawatt-hour battery system. It proposes grid power delivered through Sulphur Springs Valley Electric Cooperative and Arizona Electric Power Cooperative to a utility-owned substation. The county application does not identify SpaceX; the connection is established by SpaceX’s project page and Tombstone Resources’ statement that SpaceX would host a community town hall.
SpaceX plans major AI campuses Power, water and local review
Two proposed campuses in Texas and Arizona would add major computing capacity. Their distinct power plans and unresolved local approvals will shape what gets built and how communities are affected.
Two campuses, different power plans
The proposals rely on different sources of electricity, with local infrastructure decisions still ahead.
- Plans a gas-fired plant to generate its own electricity.
- Facility water use and plant capacity are not specified in the city notice.
- Application proposes grid power through local cooperatives.
- Proposes dry cooling and estimates 7–10 acre-feet of annual water use at full build-out.
What communities may weigh
The scale brings possible jobs and infrastructure commitments alongside questions about local costs and services.
Hiring remains a projection
SpaceX projects more than 3,000 construction jobs and over 500 permanent Texas positions.
Texas use remains unclear
SpaceX cites regional water and wastewater funding, but has not disclosed the computing facility’s direct water use.
Abatement not decided
A Texas property tax abatement is scheduled for consideration; approval and final terms remain unclear.
What happens next
The proposals depend on review and approvals before their planned scale can be realized.
City and county processes will consider the projects and related decisions.
Arizona’s proposed electricity supply still depends on utility and regulatory approvals.
Final timing, financing, water use and whether either campus reaches full scale remain unsettled.
AI Campuses Put Local Utilities in Focus
The plans show SpaceX seeking large-scale computing capacity on the ground as it expands its AI operations. The projects would bring major construction activity and, according to the company and project documents, hundreds to thousands of jobs. Their scale also puts local decisions about power infrastructure, land use and public incentives at the center of whether the campuses proceed.
The power strategies are distinct. The Texas facility would generate its own electricity with a gas-fired plant, while the Arizona campus proposes drawing power from the grid, reaching about 6 gigawatts at full build-out. That demand could make utility and regulatory decisions consequential for the project and the surrounding region. SpaceX says the Arizona project would use dry cooling and consume little water, but those figures come from the project application and will be subject to review.
For nearby communities, the central practical questions include how infrastructure costs and benefits are distributed, whether promised job numbers materialize, and what local services the projects require. SpaceX says it has committed $220 million for water and wastewater infrastructure in Brownsville and Cameron County, including $40 million it says has already provided. That commitment concerns regional infrastructure; the company has not disclosed the Texas computing facility’s own water use.

From Orbital Computing to Ground Sites
SpaceX previously argued that demand for AI electricity could not be met by terrestrial facilities without hardship to communities and the environment, and presented computing in orbit as a potential answer. The company’s February 2 announcement of its acquisition of xAI outlined that idea. The two campus proposals are a substantial ground-based development alongside that longer-term ambition, not evidence that SpaceX has abandoned its space-computing plans.
SpaceX says the Texas facility would also help develop and test technologies for future space-based computing. The company’s November 12 statement calls the two projects more than $74 billion in planned American investment; that is a proposed investment total, not money already spent. Reuters reported that SpaceX’s AI segment generated more than half of the company’s revenue in the third quarter, underscoring the growing commercial importance of its AI operations.
The Arizona application gives more detail about cooling and water than the Texas materials do. It proposes dry cooling without cooling towers and estimates 7 to 10 acre-feet of water per year at full build-out, mostly for staff. The application compares that amount with a quarter-section center-pivot field’s estimated use of 400 to 600 acre-feet annually. The two projects therefore should not be treated as having the same energy or water plans.
“Together, they represent more than $74 billion in planned American investment.”
— SpaceX
Power, Water and Incentives Still Open
Several material details have not been established in the documents described. The Texas project’s computing capacity and direct water use are not specified in the announcement or city notice. The size and final terms of any Texas property tax abatement also remain unclear. Starbase’s City Commission is scheduled to consider an abatement on December 9, but the notice does not establish that one will be approved.
For Arizona, the project application lays out a grid-power plan, but it remains unclear whether the relevant utility and regulatory approvals will authorize the electricity arrangement behind SpaceX’s promised lower power bills for local cooperative members. The application’s water estimates and job projections are proposed figures, not proof of actual consumption or hiring. Final construction timing, financing details and whether the projects will be built to their proposed full scale have not been established.
The Texas turbine figures come from The 956 Report’s account of an air registration, not from the city notice’s summary. The permitted configuration and operating limits will depend on applicable reviews. The planned combined investment should also be understood as a company-reported figure for proposed projects, rather than confirmed spending to date.
County and City Reviews on December 9
The next scheduled local decisions are both set for December 9, 2026. The Cochise County Planning and Zoning Commission is due to hold a hearing on the Arizona application. In Starbase, the City Commission is scheduled to consider a property tax abatement related to the Texas project. Those proceedings may clarify land-use conditions and the proposed incentive, but the available information does not establish their outcomes or whether they represent every approval the projects will need.
Further milestones include review of the Arizona campus’s proposed grid connection and additional public or regulatory consideration of the Texas power plant. Readers should watch for updated project filings that spell out capacity, water requirements, emissions limits, construction schedules and the terms of any local agreements. Until those details and approvals are available, the investment totals and operating plans remain proposals rather than completed developments.
Key Questions
