Lefdal Mine Data Centers operates a single, highly distinctive colocation facility built inside a former underground olivine mine on the west coast of Norway, between the towns of Måløy and Nordfjordeid in Vestland county. Rather than a conventional purpose-built data hall, the site occupies six levels and 75 chambers carved into a mountain, with up to 120,000 square meters of potential white space and a design capacity of up to 200 MW, cooled largely using cold water drawn from an adjacent fjord. Its differentiators are physical: 700 meters inside solid rock and up to 60 meters below sea level, the mountain hall offers natural EMP shielding, a single monitored entrance, and access to some of Europe’s cheapest renewable hydroelectric power. As of 2025-2026, the facility hosts Norway’s national supercomputer Olivia, operated by the state research-infrastructure company Sigma2, alongside earlier tenants including IBM and Germany’s Friedhelm Loh Group.
