# Cerebras Mikkeli AI data centre locks 165MW _Cerebras and Compute Nordic Finland will build a 165 MW AI data centre in Mikkeli, with 50 MW under construction under seven-year contracts._ **Published:** 2026-09-01 **Source:** https://www.startuphub.ai/ai-news/public-companies/2026/cerebras-mikkeli-ai-data-centre-locks-165mw --- The [Cerebras Mikkeli AI data centre](https://investors.cerebras.ai/news-releases/news-release-details/cerebras-and-compute-nordic-finland-announce-new-165-mw-ai-data) is a 165 MW phased build in Finland, and construction on the first 50 MW is already under way.

That structure matters. It isn't speculative capacity. ## Inside the Cerebras Mikkeli AI data centre The campus is built for density and efficiency, not just scale. [Cerebras Systems](https://www.startuphub.ai/ai-news/startup-news/2026/cerebras-seeks-4-8b-ipo-amid-ai-chip-demand) says its wafer-scale architecture pulls more AI output per megawatt, and Mikkeli pairs that with closed-loop cooling that recirculates water. Heat reuse is designed in from the start, so waste thermal energy can feed the surrounding community. Capacity scales 50 MW, then 80 MW, then 165 MW as it's delivered. ## Why this matters, and what still isn't fixed For builders, this is a long-term anchor, not a construction spike. Ramboll's Finnish Data Center Market Study estimates €1.0, 1.7 billion in regional investment at full scale, with 80, 250 direct permanent jobs and €0.8, 2.5 million per year in property tax. Compute Nordic Finland leads development and operations, with the City of Mikkeli and Finnish engineering and energy partners. What's not disclosed is pricing, power source mix, or customer allocation. The gap to watch is utilization. [Andrew Feldman](https://www.startuphub.ai/ai-news/funding-round/2026/cerebras-ceo-on-5-55b-ipo-extraordinary-demand), CEO and co-founder of [Cerebras](https://www.startuphub.ai/ai-news/startup-news/2026/cerebras-seeks-4-8b-ipo-amid-ai-chip-demand), framed Mikkeli as efficiency-first infrastructure. Compute Nordic Finland CEO Pyry Virrantaus called it contractually committed demand rather than a bet. Nordic sites have become the pattern for US chip firms seeking power, cooling, and heat reuse. Mikkeli fits that shift, but leaves the question of who fills 165 MW and when. --- Original analysis from [startuphub.ai](https://www.startuphub.ai), the #1 AI startup directory. © StartupHub.ai.
