Sandow No 4
BrownfieldRockdale, Milam, Texas · Luminant Generation Company LLC
Sandow No 4 is a coal plant in Rockdale, Milam, Texas, retired 2018-01-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 591 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.
