atNorth and Kesko Begin Heat Reuse from Espoo Data Center

March 27, 2026
atNorth has activated a heat reuse partnership with Kesko Corporation, supplying recycled heat from its FIN02 data center in Espoo to a nearby retail store. The project reduces Kesko’s district heating emissions by about 200 tons of CO2 annually.

Nordic data center operator atNorth has started a heat reuse project with Kesko Corporation, announced in a press release. The initiative, which went live in November 2025, delivers recycled heat from atNorth’s FIN02 data center in Espoo to an adjacent Kesko retail store.

The recovered heat now supplies nearly all the heating needed by the store, reducing its reliance on district heating and cutting emissions for both companies. Kesko expects the project to lower its district heating emissions by around 200 tons of CO₂ equivalent each year, or approximately 0.9% of its total district heating emissions.

The collaboration is part of atNorth’s wider effort to integrate circular energy solutions across its Nordic data centers. The company has launched similar heat reuse projects in Iceland, Denmark, and Sweden, supporting local energy networks and improving overall facility efficiency.
