Ormesa I
BrownfieldHoltville, Imperial, California · Ormat Nevada Inc
Ormesa I is a former geothermal site in Holtville, Imperial, California, retired 2018-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 31 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.
