Finland is leading a new wave of sustainable energy innovation, and the city of Helsinki is at the center of it. Local energy company Helen has partnered with major data centers — including Equinix, Telia, and Elisa — to capture excess heat from their servers and use it to warm thousands of homes through the city’s district heating system.
Data centers generate large amounts of heat as they run, and instead of letting that energy go to waste, Helen collects it, boosts it with heat pumps, and feeds it into Helsinki’s heating network. This approach provides clean, reliable warmth for residents while cutting carbon emissions and reducing dependence on fossil fuels.
The partnerships are already having a major impact. Heat from Telia’s Pitäjänmäki data center alone could eventually cover the heating needs of up to 14,000 apartments, with potential to grow even further. Equinix and Elisa are contributing significant volumes as well, helping Helen move toward its goal of carbon neutrality by 2030.
The system delivers both environmental and economic benefits. Reusing heat lowers energy costs for consumers and supports a more stable local grid. It also turns data centers — often criticized for high energy use — into contributors to clean urban heating.
Helsinki’s model is now drawing global attention as cities look for practical ways to meet climate goals. By transforming digital waste heat into a valuable resource, Finland is showing how technology and sustainability can work hand in hand.
