Puueo
BrownfieldHilo, Hawaii, Hawaii · Hawaii Electric Light Co Inc
Puueo is a former hydro site in Hilo, Hawaii, Hawaii, retired 2002-12-01. 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.
