Hauser
BrownfieldHelena, Lewis and Clark, Montana · NorthWestern Energy (MT Hydro)
Hauser is a former hydro site in Helena, Lewis and Clark, Montana, retired 2023-09-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 12 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.
