99 Islands
BrownfieldBlacksburg, Cherokee, South Carolina · Duke Energy Carolinas, LLC
99 Islands is a former hydro site in Blacksburg, Cherokee, South Carolina, retired 2018-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 6 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.
