Transalta Centralia Generation
BrownfieldCentralia, Lewis, Washington · TransAlta Centralia Gen LLC
Transalta Centralia Generation is a coal plant in Centralia, Lewis, Washington, retired 2020-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 1,052 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.
