LEFDAL MINE DATA CENTER
TOP 10 – SUSTAINABLE DATA CENTRES
LEFDAL MINE DATA CENTER
LOCATION: MÅLØY, NORWAY
COMPANY INVOLVED: LEFDAL MINE DATA CENTER
STANDOUT COMPONENTS: SEAWATER COOLING; HYDRO‐POWERED OPERATION; BELOW‐GROUND CLIMATE STABILITY
Lefdal represents one of the industry’ s most audacious repurposing projects.
A former olivine mine now serves as a naturally secure facility where frigid Norwegian fjord water provides direct cooling. The 1.15 PUE tells only part of the story – seawater cooling eliminates freshwater consumption entirely, while Norwegian hydroelectricity delivers near-zero operational carbon emissions.
The mountain provides physical security and thermal mass moderating temperature fluctuations, demonstrating how creative infrastructure reuse transforms liabilities into assets.
