Santa Maria Cogen Plant
BrownfieldSanta Maria, Santa Barbara, California · Wellhead Services, Inc
Santa Maria Cogen Plant is a natural gas plant in Santa Maria, Santa Barbara, California, retired 2014-08-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 9 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.
