IT service company Tieto is constructing a datacenter housing 50,000 servers in the City of Espoo in southern Finland. The Finnish granite bedrock is the best place for servers, according to Ari Karppinen, Tieto’s country director for Finland. Inexpensive energy, stable conditions and a good cost structure also contributed to Tieto’s choice of location.
Finland’s modern, eco-efficient datacenters have a growing demand globally, especially as the datacenters’ energy requirements are rising due to more companies using cloud services, according to Karppinen. The energy produced by Tieto’s new datacenter will be piped into the district heating system by Fortum, a leading energy company focusing on the Nordic countries, Russia and the Baltic Rim area. The energy produced is sufficient to heat 15,000 houses in Espoo.
The world’s most eco-efficient datacenter is located in the bedrock beneath the Katajanokka district of Helsinki. Run by ICT service provider Academica Oy in cooperation with Helsingin Energia, the facility has been designed to use alternative energy sources and also utilises the heat produced by the servers.
Thanks to efficient energy use, Academica is saving about EUR 150,000 from its electricity bill. For six months of the year, the datacenter makes use of district cooling produced from cold sea water. Helsingin Energia uses the energy produced by the datacenter in its district heating system to heat buildings and water in the city.
Cost-effective district cooling and cool sea water were also reasons why Google decided to locate its datacenter in a former paper mill in Summa, south-eastern Finland. CSC- IT Centre for Science has followed Google’s example by choosing another former paper mill site in Kajaani, northern Finland, to locate its energy-efficient datacenter. CSC’s facility will source its energy from a water power station and its cooling water from an adjacent river.
