Prometheus Hyperscale Evanston Campus
Evanston, Uinta County, WY
Plans have been filed for Prometheus Hyperscale Evanston Campus, a data center in Evanston, WY. The project is sized at 1,250 MW. Uinta County commissioners unanimously approved Prometheus Hyperscale's conditional use permit for independent power production and rezoning on June 17, 2026 for a 506-acre campus near Evanston. The campus is planned as a fully islanded gas-fired microgrid with no grid draw (so no Rocky Mountain Power service agreement); capacity_mw = 1.25 GW initial capacity, with a pathway to 5 GW. Construction expected within six months of final permitting, phased over 48-60 months.
