The Finnish IT service company Tieto is investing EUR 10 million in its data centre in Espoo, southern Finland. The facility won the Green Enterprise IT (GEIT) Award in 2011 and is one of the most energy efficient data centres in the world. The Power Usage Effectiveness (PUE) of the data centre in Espoo is 1.2 - 1.3. Typically, data centres PUE ranges from 1.8 to 3.0.
According to Tieto, it is expanding the data centre and doubling its capacity, making it possible to shut down two other data centres which are becoming outdated. By expanding capacity at its greenest data centre, Tieto is aiming to make its data centre services even more environmentally friendly.
Heat distributed via district heating network
Tieto is working with the Finnish energy company Fortum at the data centre in Espoo which currently produces 30 GW of heat, equivalent to the annual heat requirement of about 1500 houses. The new investments will increase the amount significantly. The heat from the data centre will be distributed to homes in Espoo via Fortum's district heating network, replacing some fossil-fuel based heat production.
“We will continue to invest in sustainable technology. Demand for cloud services continues to grow and, as we have launched a new Tieto Cloud Server, we will need more space in our data centres,” says Mikko Pulkkinen, Vice President, Tieto Managed Services. “Our goal is to replace inefficient technology with an energy-efficient IT capacity service. Investing in the new data centre also ensures the quality of our capacity services.
