About EcoDataCenter Falun Campus

EcoDataCenter's Falun main site is an operating Nordic data center campus with heat recovery and renewable power access. Expansion announced in 2023 has produced two additional wooden data center buildings, but the announced 45 MW site target is retained as a target until live capacity is explicitly confirmed.
