Helms Energy Center
BrownfieldHelm, Fresno, California · Wellhead Services, Inc
Helms Energy Center is a natural gas plant in Helm, Fresno, California. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 48 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.
