Williams Air Force Base
BrownfieldMesa, Arizona
Williams Air Force Base is a former superfund site in Mesa, Arizona. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 2 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.
