Ocotillo
BrownfieldTempe, Maricopa, Arizona · Arizona Public Service Co
Ocotillo is a natural gas plant in Tempe, Maricopa, Arizona, retired 2019-01-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 227 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.
