BrownfieldCenterville, Appanoose, Iowa · Interstate Power and Light Co
Centerville is a oil plant in Centerville, Appanoose, Iowa, retired 2017-11-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 60 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.
