Jefferson Street Substation
BrownfieldFarmington, St Francois, Missouri · City of Farmington - (MO)
Jefferson Street Substation is a oil plant in Farmington, St Francois, Missouri, retired 2012-03-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 6 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.
