Energy Generation and Technology Campus south of Maricopa
Also called: W Holdings data center, Ak-Chin Energy Generation and Technology Campus
W Holdings, a Tempe farm and land company, plans a $10 billion data center campus with its own gas power plant on about 500 acres south of Maricopa. The county approved a land-use plan change in 2025. The Ak-Chin Indian Community raised concerns about cultural sites.
Where things stand: County supervisors approved a land-use plan change in November 2025. The land still needs rezoning before anything can be built.
🕒 Latest update (Nov 19, 2025): County supervisors unanimously approved the land-use plan change.

Local votes and rules
🗺️ 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.
