The Pinal County Planning and Zoning Commission voted 7-2 on April 16 to recommend approval of the rezoning for the La Osa Energy Center, a combined data center and power generation project spanning 3,385 acres south of Eloy. The recommendation now moves to the Board of Supervisors.
The recommendation covers Case PZ-003-26, which rezones the land from General Rural (GR) to 2,393 acres of Industrial (I-3) zoning with 992 acres of proposed open space. A companion Planned Area Development overlay, Case PZ-PD-003-26, applies 33 stipulations across the full acreage.
La Osa is the latest and largest in a series of data center and energy campuses moving through Pinal County’s approval process. In November 2025, the Board of Supervisors approved the Project Midway Data Center, a 215-acre comprehensive plan amendment near Casa Grande. That same month, supervisors approved a 495-acre data center, gas plant and battery storage campus near Maricopa, which cleared its comprehensive plan amendment stage. Both projects still require rezoning approval before construction can move forward.
Activity is not limited to unincorporated parts of the county. In October 2025, the Town of Florence approved rezoning for 1,619 acres of data center and industrial development at Dobson Farms, covering three projects projected to generate about 800 jobs and $10 million in annual tax revenue at full buildout.
