Lefdal Underground Mine

The Lefdal Mine is located in the region Sogn og Fjordane between Måløy and Nordfjordeid. It is situated next to a deep, cold fjord with a stable and ample supply of price leading CO2-neutral energy (hydroelectric). It has excellent links to the local road network, shipping port, communication and fiber networks, two local airports and a helipad on site. The town of Måløy is considered as one of the most important ports in the coastal region of Sogn og Fjordane and is able to support the technical skills and maintenance requirements for such a remote and secure data center.

The mine today consists of six levels divided into 75 chambers with a potential white space area of 120,000 m2.

The entry point leads to a 1300 meters long access road – “Spiral” – which is 14 meters wide and 8.5 meters high. The Spiral gives access to each floor level which has a central access road – “The Avenue”. The Avenue provides direct access to vacant chambers on each floor level, these chambers are the ‘Streets’ and vary in depth (average 100 meters).

With a vast usable floor space, one of the most important factors when designing the facility was the modular and scalability approach.
