TL;DR
SpaceX announced plans for two AI computing campuses: a more than $24 billion project near Brownsville, Texas, and a roughly $50 billion campus in Cochise County, Arizona. The projects still need local approvals, and details including the Texas facility’s computing capacity and water use remain undisclosed.
SpaceX announced November 12 that it is advancing plans for two AI computing campuses, one near Brownsville, Texas, and another in Cochise County, Arizona, describing the combined planned investment as more than $74 billion. Neither project has all its local approvals: Starbase officials are due to consider a tax abatement for the Texas proposal, while the Arizona county planning commission is scheduled to hold a hearing on the campus, both on December 9.
The Texas project would occupy an approximately 444-acre site near the Port of Brownsville, according to a Starbase city notice. SpaceX says it plans to invest more than $24 billion in computing infrastructure there. The notice describes a gas-fired power plant and a supercomputer facility; SpaceX says the site will generate its own electricity rather than draw from the public grid. The city document gives no generating capacity for the plant.
SpaceX describes the Arizona proposal as a roughly $50 billion campus. A Cochise County application, filed by Tombstone Resources L.L.C., covers about 747 acres near the town of Cochise and calls for up to nine computing buildings, each about 493,000 square feet. The application does not name SpaceX, but SpaceX’s project page identifies the campus, and Tombstone Resources’ statement for a November town hall said SpaceX would host the event.
The Arizona application describes a phased build-out reaching approximately 6 gigawatts of grid power, with a 24-gigawatt-hour battery system. Power would be delivered through Sulphur Springs Valley Electric Cooperative and Arizona Electric Power Cooperative to a utility-owned substation. The application estimates 7 to 10 acre-feet of water use per year at full build-out, mostly for staff, and says the campus would use dry cooling without cooling towers.
Two AI campuses face local decisions
SpaceX announced major computing projects in Texas and Arizona. Local approvals, power plans and community impacts remain central questions.
AI Compute Meets Local Power Decisions
The proposals would make local electricity infrastructure and land-use decisions central to SpaceX’s effort to expand its AI computing capacity. The Arizona application’s projected 6-gigawatt demand is a major planning figure for the county and the cooperatives that would deliver power. The Texas plan takes a different approach, with an on-site gas-fired power plant rather than a stated draw from the public grid.
Those choices have practical consequences for nearby communities: utility planning, air emissions, water use, public services and tax arrangements. SpaceX says the Arizona project would lower power bills for cooperative members, but whether that happens depends on an electricity arrangement that still requires regulatory review. The Texas project’s proposed tax abatement also remains before local officials.
The scale of the spending is relevant to the company’s strategy as well as to local governments. SpaceX has presented computing infrastructure on Earth as a step toward future space-based computing. The announcement also comes after the company said in February that it had acquired xAI. Reuters reported that SpaceX’s AI segment generated more than half of its revenue in the third quarter; that figure is Reuters’ reporting, not a detail established by the local project filings.

Two Sites, Different Power Plans
In its February announcement about acquiring xAI, SpaceX argued that terrestrial electricity demand for AI could not be met in the near term without hardship to communities and the environment, and pointed to data centers in orbit. The new proposals focus on large facilities on the ground. SpaceX says the Texas site will also help develop and test technologies for future space-based computing.
The two applications set out contrasting designs. In Arizona, the county filing describes grid-supplied power, dry cooling and natural-gas standby generators for outages and testing. It estimates up to about 10 megawatts of standby generation per building. The application says the site’s estimated annual water use is comparable to that of roughly 20 to 30 Arizona homes, while a 160-acre center-pivot field can use 400 to 600 acre-feet annually. Those figures are comparisons in the application, not independent measurements of the proposed facility’s eventual use.
For Texas, local outlet The 956 Report said an air registration filed with the Texas Commission on Environmental Quality describes an initial temporary configuration of 35 natural-gas turbines totaling about 748 megawatts, followed by eight larger turbines totaling about 708 megawatts. Those details come from the outlet’s account of the filing; the Starbase notice itself confirms a gas-fired plant but does not list its capacity.
“Together, they represent more than $74 billion in planned American investment.”

Capacity, Water and Approvals
Important project details remain unresolved or undisclosed. SpaceX and the Starbase notice have not stated the Texas computing facility’s capacity or how much water it will use. The size and terms of the proposed Texas tax abatement are also not specified in the source material. The turbine figures reported by The 956 Report are based on an air registration and do not replace the city notice’s lack of a stated generating capacity.
In Arizona, the county application estimates water use and power demand, but those are project estimates rather than operating records. SpaceX has promised lower bills for local cooperative members; it remains unclear whether the Arizona utility regulator will approve the electricity arrangement behind that pledge. The projects’ final designs, construction schedules and full approval status are not yet established.
SpaceX says it has committed $220 million to expand Brownsville and Cameron County water and wastewater infrastructure, including $40 million it says it has already provided. It says the work would add about 20 million gallons per day from sources independent of the Rio Grande. The company also says it is not acquiring water rights, prepaying utility rates or receiving preferential access to regional water. These are company statements; they do not disclose the Texas computing facility’s own water demand.
December 9 Local Decisions
The next scheduled milestone is December 9, 2026. Cochise County’s Planning and Zoning Commission is set to hold a hearing on the Arizona application. On the same day, the Starbase City Commission is scheduled to consider a property tax abatement connected to the Texas proposal. The source material does not say that either meeting will result in final project approval.
Further review will be needed to establish what the projects can build and operate, including any applicable permitting and utility decisions. For Arizona, the electricity arrangement and promised cooperative-member bill reductions remain outstanding questions. For Texas, public details on computing capacity, facility water use and the tax proposal would help clarify the project’s local effects.
Key Questions
What has SpaceX announced?
SpaceX says it is advancing two AI computing projects: a more than $24 billion facility near Brownsville, Texas, and a roughly $50 billion campus in Cochise County, Arizona. The company puts the combined planned investment above $74 billion.
Have the projects been approved?
The source material describes upcoming local decisions, not completed approvals. Cochise County’s Planning and Zoning Commission is scheduled to hear the Arizona application, and Starbase’s City Commission is scheduled to consider a Texas property tax abatement on December 9, 2026.
How will the facilities get electricity?
SpaceX says the Texas site will generate its own electricity using a gas-fired power plant. The Arizona application describes grid power delivered through two electric cooperatives, plus standby natural-gas generators and a battery system.
How much water will the projects use?
The Arizona application estimates 7 to 10 acre-feet a year at full build-out, mostly for staff, and describes a dry-cooled design. SpaceX has not stated the Texas computing facility’s water use.
What remains unknown about the Arizona project?
The project still faces county review, and the electricity arrangement behind SpaceX’s promised lower cooperative-member bills awaits regulatory approval. The final design, schedule and operating outcomes are also not established in the material available.
