BrownfieldSleepy Eye, Brown, Minnesota · Sleepy Eye Public Utility Comm
Sleepy Eye is a oil plant in Sleepy Eye, Brown, Minnesota, retired 2010-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 2 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.
