Lake Catherine
BrownfieldJones Mill, Hot Spring, Arkansas · Entergy Arkansas LLC
Lake Catherine is a natural gas plant in Jones Mill, Hot Spring, Arkansas, retired 2013-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 200 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.
