Previously known as DC1-Stavanger data centre is located in Rennesøy in Norway. The site is a former NATO ammunition storage facility converted into a unique high security colocation data centre with 13 600 m2 technical/white space initial availability. The infrastructure has been designed to be expanded up to 26MW. The main data centre comprises three 2 storey concrete buildings built within the mountain.


DC1-Stavanger has multiple grid supplies each fed from multiple hydro electricity power plants. Outstanding robustness of supply is the result (estimated 99.99997%) with even further additional levels of security in terms of N+1 prime rated generators. Phase 1 expandable to 26MW.


DC1-Stavanger has a cooling source available from an adjacent deep water fjord. At levels below 75 m depth the water temperature is stable at 8 oC (46F) all year round. Our cooling system uses gravity effect to bring the cold water from a depth of 100 m to the data centres cooling station without using any energy.

The cooling solution (including cooling station, chilled water pipework and pumps) is fully duplicated providing an N+N solution. Because there are few moving parts (circulating pumps) the solution is extremely robust and reliable. Server rooms will have available N+N chilled water under the raised floor. In row cooling will be installed to client specification using hot isle technology. Standard power densities from 2-6 kW/m2, bespoke solutions can be accommodated up to 20 kW/m2.
