Arizona data center projects in government records, 2026

5 data center projects found in Arizona city and county records dated April 26 to October 26, 2026: zoning hearings in Mesa and Pinal County, a pre-annexation agreement in Glendale and a data center permit waiver in Phoenix. None of the records we opened state a generator or turbine count; where news reports a count, this page says so. Every project links to its government record.

Maricopa County air permit reports could not be read automatically, and the Maricopa County Board of Supervisors agenda portal and the Casa Grande agenda center block automated access, so projects there are missing or listed as leads. This is a sample of projects, not a complete list.
