Chalk Point Steam
BrownfieldAquasco, Prince Georges, Maryland · Lanyard Power Holdings, LLC
Chalk Point Steam is a coal plant in Aquasco, Prince Georges, Maryland, retired 2021-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 728 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.
