Allen
BrownfieldMemphis, Shelby, Tennessee · Tennessee Valley Authority
Allen is a coal plant in Memphis, Shelby, Tennessee, retired 2018-03-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 990 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.
