DC2-Telemark is located in a historic region of Norway and is being built on a ‘brown field’ site with a 10MW supply initially available. First phase is a fully operational Tier lll 1MW facility, with 4 new buildings and up to 25 MW + total capacity planned. Data centres can be bespoke to client requirements.


DC2-Telemark is uniquely placed not only in Norway but in Western Europe in the number of hydro electric plants it has in close proximity to the site. There are 6 hydro electric plants in the valley and 2 underground hydro electric plants within 2 km of the site (1 and 2 ). The National Grid has 2x 500MW within 1km of the site (3). There are 2 x 10MW on site (outlined in yellow) with capability to expand to 100MW.


DC2-Telemark has a unique cooling source available from an adjacent water supply which is first used for hydro generation in the mountain. As the water exits the mountain at a consistent year round temperature near the data centre it is piped to a heat exchanger in the cooling station. It is then discharged into the river where the raise in temperature helps fish breed.

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 density from 2-6kW m2, bespoke solutions can be accommodated up to 20 kW m2.
