Flexible Data Centre Site


Flexible and future proof data centre site in the Oslo region. 

Data Centre Campus

DC3-Oslo is our newest data centre site located in Enebakk, just 20 km outside Oslo, the capital of Norway. Green Mountain has acquired a 75 000 m2 (800 000 ft2)  area with line-of-sight capacity of 75 MW. The official construction of the first 4 MW building started September 1st and was completed October 2020. An international client has already signed a contract for the entire first data centre building. In summary, the site is perfectly situated in terms of power supply, infrastructure and connectivity close to Norway’s most populated area. Furthermore, a colocation data centre is planned as the next step of the construction phase.

Flexible and scalable data centre site

The location is ideal for clients with specific requirements for growth.  They can start with a limited footprint  like singular racks in a colocation centre to support Proof-of-concept or operational concepts. Furthermore, we can support any avenue through to individual buildings or modules with no limit in regards to power capacity. We offer rapid deployment of new modules, and solutions can be designed and delivered to support “any” power density, cooling, security solutions etc.

Most importantly, with three data centres located in different geographical and climatic zones, we can offer geographic redundancy. But still leverage the advantage of integrated network infrastructure.

Renewable power supply and energy efficiency

The new data centre site has two independent power grid suppliers and is located in the vicinity of several hydropower  plants. Therefore, we have access to enough power to secure the necessary capacity to develop the campus for the future while securing resilience and redundancy. In addition, Norway is the #1 producer of sustainable hydropower in Europe. This gives us reliable access to 100% renewable energy from a robust power grid. Moreover, Green Mountain also uses the Norwegian wet and cool climate to our advantage. As a result, we have free cooling for more than 95 % of the year. The cold and wet climate combined with our innovative cooling solutions result in an efficiency that is 25-30% better than the European average.


Green Mountain’s DC3-Oslo data centre site in an area with several connectivity providers already present. Due to the increased need for fibre at the site, additional new capacity is being planned and built in the area. As a result, this makes the data centre site one of the most connected campuses in the region.
