Dolphus M Grainger
BrownfieldConway, Horry, South Carolina · South Carolina Public Service Authority
Dolphus M Grainger is a coal plant in Conway, Horry, South Carolina, retired 2012-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 163 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.
