Marshall County Landfill Solar
BrownfieldMarshalltown, Iowa
Marshall County Landfill Solar is a former landfill site in Marshalltown, Iowa. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 0 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.
