What is established
Planning. 1.3 GW announced (gross site power); owned or developed by Prometheus Hyperscale.
What is not disclosed
Accelerator count, hardware platform, project capex, timeline, named tenant, power source, cooling technology — not disclosed by any source on this page. Recorded as unknown, never as zero.
Analyst note
506-acre site on founder Trenton Thornock's family ranch; unanimous Uinta County conditional-use approval June 2026. 'Prometheus says construction will begin within six months of final permitting and take four to five years.' Mostly natural-gas powered, closed-loop water-glycol cooling. Capex null: reported $30B covers two Wyoming projects (Evanston plus a proposed Casper-area site), not this campus alone. Former BP CEO Bernard Looney leads the buildout. Some reports cite expansion potential to 5GW.
Corroborated by more than one source, but not yet backed by physical evidence.
