Lansing
BrownfieldLansing, Allamakee, Iowa · Interstate Power and Light Co
Lansing is a coal plant in Lansing, Allamakee, Iowa, retired 2023-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 341 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.
