BrownfieldMabelvale, Pulaski, Arkansas · Entergy Arkansas LLC
Mabelvale is a natural gas plant in Mabelvale, Pulaski, Arkansas, retired 2016-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 78 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.
