Dolet Hills
BrownfieldMansfield, DeSoto, Louisiana · Cleco Power LLC
Dolet Hills is a coal plant in Mansfield, DeSoto, Louisiana, retired 2021-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 721 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.
