Work has started on a 165MW data center campus in Mikkeli, Finland, for Cerebras.

Plans for the data center were revealed by the company yesterday, September 1, and construction on the first 50MW has begun.

The data center campus is being developed in partnership with Compute Nordic Finland.

It will use a closed-loop cooling system and is designed to support waste-heat recovery to supply excess heat to the local community.

“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.”

The project will be constructed in phases, starting with 50MW before scaling to 80MW and later 165MW. Between €1bn and €1.7bn ($1.16bn-$1.97bn) is expected to be invested in the project.

Mikkeli is located in southern Finland, around 230km (143 miles) northeast of Helsinki. That Compute Nordic was expanding its land holdings in Mikkeli was reported in early 2026, along with suggestions that two 100MW data centers could be built on the site. Compute Nordic reportedly operates one site in Sogndal, Norway.

FCDC Corp, Orka Technologies, and Regant Oy are also targeting projects in Mikkeli.

Cerebras is best known for its wafer-scale chips, and also offers cloud services based on its hardware. The company previously said it would target having 200MW of capacity online in Europe by the end of 2027, with a focus on France and the Nordics. Elsewhere, Cerebras has signed a lease for 40MW of capacity at a Digi Power X data center in Columbiana, Alabama.

The company also has inference clusters live in Santa Clara and Stockton, California (the latter at Nautilus’ floating barge facility), and Dallas, Texas. The company is rolling out clusters in Minneapolis, Minnesota, and works closely with G42, including on a supercomputer in India.

In Canada, the company is set to lease capacity in Montreal at a Bit Digital facility, and in Saskatchewan and Manitoba from Bell. The firm is planning a large-scale deployment in Guyana.

In its recent earnings call, the company noted that its revenue reached $210m, a significant increase from the prior year, but it had a net loss of $450.4m, down from $309.5m in net income in Q2 2025. The quarter saw data center capacity come online and under contract for delivery by the end of 2027, increasing total capacity to more than 600MW. The firm says its total pipeline is in the gigawatts.
