SpaceX Campuses Will Generate Their Own Power
The $74 billion AI plan spans Texas and Arizona, but the Arizona site still needs county approval before construction can proceed.

SpaceX said on November 12 that it plans to invest more than $74 billion in two AI supercomputing campuses, one at Starbase in Texas and one in Cochise County, Arizona. The investments are announced plans, not completed or shipped capacity, and the Arizona campus still needs county approval.
Why it matters
The scale of the plan signals that AI compute demand is pulling private infrastructure spending into power generation and grid work at a size previously associated with utilities. AI accounted for more than half of SpaceX revenue in the third quarter, which helps explain why the company is committing capital to dedicated campuses rather than relying on shared cloud capacity.
The announcement is a company-reported investment plan rather than a measured capacity figure, so no compute performance or power-density specification has been published in the source. The reported facility figures are a 444-acre Starbase site, a self-supplied gas-fired power plant, and dry cooling that uses no industrial groundwater, with the Arizona campus relying on the same approach. Unresolved: the megawatt capacity, chip count, and per-site power draw are not stated.
The players
SpaceX
A rocket and satellite company whose AI business now generates more than half its revenue, and which is building dedicated supercomputing campuses in Texas and Arizona.
The details
The Starbase campus is designed to generate its own electricity from an on-site gas-fired plant instead of drawing from the public grid, which reduces dependence on local utility capacity. Its cooling approach uses dry cooling, a method that rejects heat to air rather than evaporating water or pumping industrial groundwater. SpaceX is also working with local electric cooperatives on regional grid upgrades, which are projected to cut members' bills by up to 20%.
Timeline
November 12: SpaceX announced plans for the $74 billion AI campus investment.
Third quarter: AI contributed more than half of SpaceX revenue.
December: A hearing is scheduled on the petition opposing the Arizona campus permit.
The Tech Race
The SpaceX plan places the company in a race where AI compute capacity is being secured through owned sites rather than leased cloud space, a pattern that has been driven by the largest cloud providers. Its move into self-generated gas power and dry cooling indicates that competitive advantage in AI now depends as much on energy and siting as on chip access.
Residents near the Starbase and Cochise County sites would see construction activity and new permanent roles, and electric cooperative members could see bill reductions of up to 20% if the regional grid upgrades proceed as projected. The Arizona campus's timeline is uncertain because it still depends on county approval and a contested permit.
The takeaway
The trajectory to watch is whether AI operators keep building self-powered campuses as a default, and the December Cochise County hearing is a concrete checkpoint for the Arizona portion of the plan. Track that hearing's outcome and any published megawatt figures for either site to see whether the projected job and bill-reduction claims hold.
What happens next
A December hearing will consider the petition opposing the Arizona campus permit, which must be approved by Cochise County before that campus can proceed.
