Lake Preston
BrownfieldLake Preston, Kingsbury, South Dakota · Otter Tail Power Co
Lake Preston is a oil plant in Lake Preston, Kingsbury, South Dakota, retired 1978-01-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 24 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.
