BrownfieldColstrip, Rosebud, Montana · Talen Montana LLC
Colstrip is a coal plant in Colstrip, Rosebud, Montana, retired 2020-01-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 716 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.
