Red Cedar
BrownfieldCedar Rapids, Linn, Iowa · Interstate Power and Light Co
Red Cedar is a natural gas plant in Cedar Rapids, Linn, Iowa, retired 2018-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 23 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.
