Data centers in Pinal County

The Pinal County Board of Supervisors voted 5-0 on November 19, 2025 to approve a comprehensive plan amendment for Project Midway, a 215-acre data center campus proposed by LPI Group at the southwest corner of Selma Highway and Midway Road south of Casa Grande, after unanimous recommendations from the Citizens Advisory Committee and Planning and Zoning Commission.

Pinal County supervisors unanimously approved a land-use amendment for a roughly 400-acre Energy Generation and Technology Campus near State Route 347 and Louis Johnson Drive south of the city of Maricopa, developed by Tempe-based W Holdings. The roughly 10 billion dollar project pairs a data center with a battery energy storage system and a natural gas power plant, and is projected to use about 500 acre-feet of water a year, less than the housing or farming uses previously approved for the same land.

Vermaland's La Osa project would have put a data center and power complex across 3,385 acres south of Eloy along the Greene Canal and Santa Cruz Wash. After sustained resident opposition, the developer cut the plan from 59 buildings and up to 3 gigawatts down to about 11 buildings capped at 1 gigawatt with water and cost concessions, but the Pinal County Board of Supervisors voted 4-1 on August 26, 2026 to deny the rezoning after nearly five hours of public comment, with 123 letters opposed versus 16 in support.
