Project Midway data center campus southwest of Casa Grande
Also called: Project Midway
IDM Companies wants to build a data center campus on about 216 acres of rural land southwest of Casa Grande, next to a planned gas power plant. The county changed its land-use plan in 2025, but the rezoning has not been decided.
Where things stand: County approved a land-use plan change in November 2025. The rezoning (case PZ-008-26) went to the Planning Commission in July 2026 and was put off to a later date.
🕒 Latest update (July 16, 2026): Planning Commission heard the rezoning to industrial and voted to continue it to a later date, citing questions such as who the end user is.

🗺️ 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.
