White River (WA)
BrownfieldSumner, Pierce, Washington · Puget Sound Energy Inc
White River (WA) is a former hydro site in Sumner, Pierce, Washington, retired 2004-01-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 70 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.
