Alliant SBD 9402 Climax is a oil plant in Ft. Madison, Lee, Iowa, retired 2011-03-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 8 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.

Why this site is datacenter-attractive: a oil plant of this scale leaves behind a high-capacity grid interconnection that a new load can re-use, frequently shaving years off the interconnection queue. Retired-plant sites also tend to be already zoned for heavy industrial use with established road, rail, and water infrastructure.
