Google is Transforming Data Center Waste Heat into Community Warmth in Finland

Google is Transforming Data Center Waste Heat into Community Warmth in Finland

In a significant step towards sustainability, Google has partnered with Haminan Energia to recover and distribute heat from its data center in Hamina, Finland, to the local heating network.



Revolutionizing Heat Recovery: Google Finland’s Initiative


Google, in collaboration with Haminan Energia, has announced a pioneering project to capture heat generated by its Hamina data center and distribute it to the local district heating network. This innovative approach marks Google’s first offsite heat recovery project, aiming to significantly reduce the environmental footprint of its operations.


The Hamina data center, operational since 2011, uses seawater for cooling, making it one of the most energy-efficient data centers globally. Now, this facility will take a step further by contributing to the local heating network, providing a sustainable and eco-friendly heat source.



Key Facts and Developments


  • Heat Recovery Project: Google’s Hamina data center will reroute heat produced by its servers to Haminan Energia’s district heating network, which supplies heat to local households, schools, and public buildings.


  • Environmental Impact: This initiative is expected to cover 80% of the local district heating network’s annual heat demand, significantly reducing the area’s carbon footprint.


  • Carbon-Free Energy: The heat recovered from the data center will be 97% carbon-free, aligning with Google’s ambitious goal to achieve net zero emissions across its operations by 2030.


Kalevi Mattila, COO of Haminan Energia, emphasized the project's importance, stating

"This new cooperation with Google ensures more affordable and sustainable heat for our customers."


Google’s Commitment to Sustainability


Google's parent company, Alphabet, announced in 2020 its goal to operate entirely on carbon-free energy by 2030. The Hamina project is a crucial part of this vision, showcasing how technological innovation can support environmental sustainability.


Jukka Vainonen, Site Operations Manager at Google, highlighted the broader impact of the initiative,


"Hamina is only the start. Heat recovery is a major opportunity for energy conservation and transition, and Google is working to make it a reality in our data centers worldwide."

Significant Milestones


  • 2011: Google’s Hamina data center begins operations, using seawater for cooling.

  • 2020: Alphabet sets a goal for 24/7 carbon-free energy by 2030.

  • 2024: Launch of Google’s first offsite heat recovery project in Hamina, Finland.


This project is not only a testament to Google’s commitment to sustainability but also an excellent example of how corporations can collaborate with local communities to create innovative solutions for environmental challenges.



The Future of Heat Recovery


Google plans to expand its heat recovery initiatives to other data centers globally, enhancing energy efficiency and supporting local communities. As the demand for data center resources grows, such sustainable practices will be critical in mitigating climate impact.


Ilari Soosalu, Mayor of Hamina, expressed pride in the partnership,


"Google is an excellent example of a company with a strong commitment to a sustainable future. We are proud to be the hometown of Google in Finland."


Google Finland’s Heat Recovery: A Model for Sustainable Innovation


Google Finland’s heat recovery project is a landmark development in the journey towards sustainable energy solutions. By leveraging the waste heat from its data center, Google is not only reducing its carbon footprint but also providing a valuable resource to the local community.


This initiative sets a precedent for future projects, demonstrating the potential of corporate and community collaboration in achieving environmental sustainability.
