Redfield
BrownfieldRedfield, Spink, South Dakota · NorthWestern Energy - (SD)
Redfield is a natural gas plant in Redfield, Spink, South Dakota, retired 2014-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 4 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.
