Capitol Heat and Power
BrownfieldMadison, Dane, Wisconsin · State of Wisconsin
Capitol Heat and Power is a natural gas plant in Madison, Dane, Wisconsin, retired 2011-05-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 3 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.
