Current canonical record

640-acre campus. Dedicated 138 kV substation with 120 MW initial capacity, infrastructure for full 1 GW+ build-out. Originally planned at 120 MW, expanded to 1.2 GW+.

Prometheus announced on June 17, 2026 that it received unanimous Conditional Use Permit approval from the Uinta County Board of Commissioners for its flagship data center campus near Evanston. The permitted site is 506 acres, designed for 1.25 GW of initial capacity with a development path to 5 GW, using an islanded on-site microgrid and closed-loop liquid cooling. Use planned, not under-construction, because the source describes a permitting milestone rather than a construction start.
