Data centers are coming to Pima County, whether residents like it or not.
The Pima County Board of Supervisors has approved a new data center despite major community opposition and no end user formally lined up.
Amazon was outed earlier this summer as the longtime, unofficial end user lined up for the 290-acre data center, Project Blue, but the e-commerce giant reportedly backed out around the beginning of this month after the developer, Beale Infrastructure, nixed water cooling in favor of the more electricity-dependent air cooling process.
Amazon’s departure was uncovered during the Arizona Corporation Commission (ACC) hearing earlier this month by sources first reported on by the Arizona Daily Star. ACC approved, 4-1, a decade-long Energy Supply Agreement between Tucson Electric Power (TEP) and the developer to power Project Blue.
Beale Infrastructure made the cooling process switch after the Tucson City Council voted unanimously to deny access to their reclaimed water system back in August. Tucson Mayor Regina Romero also pledged to place limits on future data centers.
The days leading up to the council vote were filled with contentious community information meetings on the project.
Per 13 News, multiple unnamed sources told Pima County Supervisor and Tucson City Councilman Paul Cunningham that up to eight other companies expressed interest in taking Amazon’s place. Sources conflicted on whether one of the companies is Meta, or whether Meta had already backed out as Amazon had.
Project Blue’s developer, Beale Infrastructure, presented the proposed data center as both an economic driver and environmentally friendly operator: “no risks or financial burdens [will be] passed on to other customers,” their representatives promised in their presentations during the community information meetings.
Opponents argue these data centers will further strain an already stressed water supply and electric grid, ultimately leading to scarcity as well as higher fiscal and health costs for the consumer.
It was the promised economic benefits that won over the 3-2 majority of Pima County supervisors. The two supervisors against the data center, Andres Cano and Jen Allen, expressed concerns over the long-term unknown impacts on the environment and community health.
Pima County’s vote came several weeks after ACC approved Beale Infrastructure’s application for Project Blue.
Data centers are the powerhouse for platforms covering virtually every aspect of modern life online: government, streaming, remote work, cloud storage, e-commerce, education, finance, and healthcare.
An independent Economic Impact Study on Project Blue projects a $3.6 billion total capital investment, $250 million in tax revenues, 180 new jobs by 2029, and over 3,000 direct construction jobs during the building phase.
The project will be located north of Pima County Fairgrounds, at the I-10 and Houghton interchange. The development site is over a mile away from the nearest resident, located within an unincorporated area that’s part of the Southeast Employment & Logistics Center.
Beale Infrastructure is also moving on another, equally controversial data center development in Marana totaling 600 acres. Two rezoning applications were filed recently for potential data center development: Luckett North and Luckett South. Earlier this month, the town’s planning commission recommended rezoning for development.
As with Project Blue, the closest resident lives about a mile away from the proposed data center campus. It will also be an air-cooled facility.
In preparation for consideration of the data center, town officials produced two podcast episodes on the town’s data center ordinance and potential for development.
Marana Town Council is scheduled to consider the data center project on Jan. 6, 2026. Progress on the project is available for viewing on the town’s development projects and activity portal.
