Cerebras Systems announced a new AI data centre in Mikkeli, Finland, developed in partnership with Compute Nordic Finland. The facility will scale in phases to 165 MW of contracted IT capacity to deliver high-density AI compute with construction on the initial 50 MW phase already under way.
“This partnership with Cerebras is not a speculative bet on future demand — it's a contractually committed, phased build-out that reflects exactly how much AI compute the market needs today and where that need is heading,” said Pyry Virrantaus, CEO of Compute Nordic Finland. “We are proud to build that capacity in Mikkeli, alongside a partner network of local and national organizations who are ready to deliver the project and build the workforce it requires.”
More AI Per Megawatt
Cerebras (which is part-owned by Amazon Web Services and OpenAI) and Compute Nordic (developer and operator of high-density AI data centre infrastructure in Finland) say they designed the Mikkeli facility for efficiency to optimize power and water usage. The facility is designed to use closed-loop cooling systems that recirculate water rather than draw continuously from municipal supply, and the campus is designed to support waste-heat recovery, enabling thermal energy generated by AI compute into a resource for the surrounding community.
“Our architecture is built to get more useful AI output out of every megawatt we deploy,” said Andrew Feldman, CEO and co-founder, Cerebras. “Mikkeli lets us pair that efficiency with a data centre designed for closed-loop cooling and heat reuse from the ground up.”
Economic impact
Independent analysis from Ramboll's Finnish Data Center Market Study and Impact Assessment Report (12 September 2025) estimates that, at full 165 MW scale, the project represents an indicative investment of €1.0–1.7 billion for the region, supporting an estimated 80–250 direct permanent jobs and €0.8–2.5 million per year in property tax revenue. “The clearest measure of a project like this isn't the number of construction jobs it creates upfront; it's what remains ten or twenty years later,” Pyry Virrantaus said. “We looked at permanent employment, workforce pathways, local suppliers, and durable economic activity when building this out in Mikkeli.”
Network
The Mikkeli project is developed in close cooperation with the City of Mikkeli and key regional stakeholders across South Savo, supported by a network of Finnish construction, engineering, energy, recruitment, and professional services partners. Compute Nordic Finland is leading project development, operator responsibility, the customer interface, and overall programme governance.
