Corning
BrownfieldCorning, Adams, Iowa · City of Corning - (IA)
Corning is a oil plant in Corning, Adams, Iowa, retired 2006-03-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 1 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.
