MMSD Jones Island Wastewater
BrownfieldMilwaukee, Milwaukee, Wisconsin · Milwaukee Metro Sewerage Dist
MMSD Jones Island Wastewater is a natural gas plant in Milwaukee, Milwaukee, Wisconsin, retired 2013-07-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 18 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.
