Helsinki is finding a practical use for the enormous amounts of heat produced by the equipment running inside data centres. Through a collaboration between Finnish energy company Helen and telecommunications company Telia, waste heat from Telia’s Pitäjänmäki data centre is being fed into the city’s district heating network. The system is expanding as the data centre grows, with plans for the recovered heat to eventually meet the heating needs of up to 28,000 apartments. At the same time, Telia has increased its waste heat recovery capacity to as much as 90%, turning a larger share of the facility’s previously unused heat into a resource for the city.
