Jack Watson
BrownfieldGulfport, Harrison, Mississippi · Mississippi Power Co
Jack Watson is a natural gas plant in Gulfport, Harrison, Mississippi, retired 2018-03-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 296 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.
