Dave Johnston Mine / Glenrock Wind III
BrownfieldGlenrock, Wyoming
Dave Johnston Mine / Glenrock Wind III is a former mine site in Glenrock, Wyoming. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 39 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.
