Tri Cities
BrownfieldPhoenix, Maricopa, Arizona · Salt River Project
Tri Cities is a natural gas plant in Phoenix, Maricopa, Arizona, retired 2015-07-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 5 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.
