La Osa Energy Center data center and gas plant south of Eloy
Also called: La Osa Project, La Osa Energy and Data Center
Vermaland wanted to build what would have been Arizona's largest data center, with its own gas power plants, on about 3,400 acres south of Eloy. After heavy opposition it shrank the plan to 11 buildings. County supervisors still voted it down in August 2026.
Where things stand: Pinal County supervisors voted 4-1 on Aug. 26, 2026 to deny the rezoning, which ends the project as proposed.

Local votes and rules
✋ Turned down
County supervisors voted 4-1 to reject the rezoning for La Osa Energy Center near Eloy: 11 data center buildings and a 500-megawatt gas plant by Vermaland. They said no even after the developer cut the plan by 80% and offered water limits.
🗺️ Zoning change
County supervisors unanimously approved land-use plan changes for three big data center sites: La Osa near Eloy, Project Midway southwest of Casa Grande, and the W Holdings energy and tech campus south of Maricopa. These plan changes do not rezone the land; each site still needs a rezoning vote.
