Lefdal Mine Datacenter operates a single, highly distinctive facility: a colocation data center built inside a decommissioned olivine mine on Norway’s west coast, between the towns of Måløy and Nordfjordeid in Vestland county. The site spans roughly 120,000 square meters across multiple underground levels carved into the mountain, with potential capacity of up to 200MW, and is cooled using water drawn from an adjacent deep fjord rather than mechanical chillers, giving it a claimed Water Usage Effectiveness of zero. Its power comes entirely from Norwegian hydropower and wind, and its underground, below-sea-level location provides physical security as well as low-cost, low-carbon operations. Customers place their own IT equipment in halls and containerized modules inside the mine, with tenants including IBM and Norway’s national research infrastructure operator Sigma2, whose NIRD storage system and supercomputers run there. As of 2026, investment firm 3i Infrastructure has agreed to acquire a majority stake in the company for roughly €300 million, underscoring growing investor interest in HPC-focused colocation platforms.
