Viaduct
BrownfieldCape Girardeau, Cape Girardeau, Missouri · Union Electric Co - (MO)
Viaduct is a natural gas plant in Cape Girardeau, Cape Girardeau, Missouri, retired 2011-09-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 31 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.
