Westport
BrownfieldBaltimore, Baltimore City, Maryland · Constellation Power Source Generation, LLC
Westport is a natural gas plant in Baltimore, Baltimore City, Maryland, retired 2020-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 122 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.
