Hassayampa Ranch Data Center

Arizona Land Consulting's 2,077-acre tract near Tonopah, Arizona, rezoned for data centers, to be resold; 1 GW announced, no buyer, power contract or construction.

Entitled land, no buyer. Maricopa County changed the land-use plan in Dec. 2025 and rezoned the site in Apr. 2026, so the entitlements are real. No tenant, buyer, power agreement, site plan or financing is on record, and a Mar. 2026 satellite image shows undisturbed desert.
