Petersburg
BrownfieldPetersburg, Wrangell Petersburg, Alaska · Petersburg Borough - (AK)
Petersburg is a former hydro site in Petersburg, Wrangell Petersburg, Alaska, retired 2023-06-01. 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.
