Knox Lee
BrownfieldLongview, Gregg, Texas · Southwestern Electric Power Co
Knox Lee is a natural gas plant in Longview, Gregg, Texas, retired 2020-05-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 150 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.
