atNorth and Kesko Begin Heat Reuse from Espoo Data Center

Mar 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.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
