Raft River Geothermal Power Plant
BrownfieldMalta, Cassia, Idaho · US Geothermal Inc.
Raft River Geothermal Power Plant is a former geothermal site in Malta, Cassia, Idaho. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 18 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.
