Holly
BrownfieldHolly, Prowers, Colorado · Town of Holly - (CO)
Holly is a oil plant in Holly, Prowers, Colorado, retired 2006-10-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 2 MW of generation, so the grid hookup, transmission rights, and often cooling-water access are already in place — collapsing the speed-to-power timeline versus a greenfield build.
