Mammoth G2
BrownfieldMammoth Lakes, Mono, California · Ormat Nevada Inc
Mammoth G2 is a former geothermal site in Mammoth Lakes, Mono, California, retired 2013-04-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 15 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.
