Cholla
BrownfieldJoseph City, Navajo, Arizona · Arizona Public Service Co
Cholla is a coal plant in Joseph City, Navajo, Arizona, retired 2020-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 703 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.
