Watts Bar Fossil
BrownfieldSpring City, Rhea, Tennessee · Tennessee Valley Authority
Watts Bar Fossil is a coal plant in Spring City, Rhea, Tennessee, retired 2011-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 240 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.
