- Lefdal Mine Datacenter is a Tier III facility inside a protected mountain mine on Norway’s west coast. It uses renewable hydroelectricity and nearby seawater for cooling. The article reports zero operational CO₂ emissions, a zero Water Usage Effectiveness rating, and a Power Usage Effectiveness rating of 1.15 for a 5 kW rack; heated water is reused.
- The existing mine provides 120,000 m² of underground white space. The underground location is presented as secure and allows expansion with comparatively low construction cost and environmental footprint. Modular logistics can accommodate differently sized containers and single-location or dual-site configurations. Water cooling supports computing densities up to 50 kW per rack; power density, temperature, humidity, equipment, tier level and services can be customized.
- The page says global data-center growth is driven by rising internet traffic, AI, IoT, autonomous vehicles, robotics and high-performance computing, while data centers consume large amounts of electricity. It cites a historical market forecast from about USD 20 billion in 2018 to USD 30 billion by 2023. Norway’s renewable power, stable infrastructure and connectivity are cited as strengths. Lefdal claims total operating costs up to 50% lower than data centers elsewhere and lists IBM and iNNOVO Cloud as clients. SDGs 9 and 12 shown. Embedded video present; no transcript exposed.
