Compute Nordic Finland is developing an AI data centre campus at Visulahti in Mikkeli. In September 2026, Cerebras announced seven-year service orders associated with phased capacity growing from 50 MW to 80 MW and ultimately 165 MW of IT capacity. These are successive stages, not amounts to add together, and construction of the initial 50 MW phase does not establish a currently operating 165 MW facility. The planned design includes closed-loop cooling and heat recovery. A municipal study identifies the project and discusses regional investment potential, but that estimate is not a financing close. Binding grid terms, specific carrier routes, parcel-title documentation and permit identifiers were not verified in the reviewed sources.

Reviewed mik contract scope context

Source report

NYAB Finland announced a project management contract with Compute Nordic Finland on February 18, 2026. Construction depended on separate orders; eventual contract scope could reach approximately €100 million. Its historical scope included two 100 MW data halls plus supporting works, without defining the MW basis. This is neither committed campus financing nor a replacement for the later 165 MW IT plan.

Additional project facts

Reviewed mik heat context

Source report

ESE-Energia’s September 16, 2026 announcement reports a signed letter of intent with Compute Nordic Finland to assess district heating reuse. Technical, commercial and investment feasibility remained to be studied; it does not establish a heat delivery contract or completed investment.

Source

Reviewed mik lease context

Source report

The May 24, 2024 development agency announcement reports an official city decision for a roughly ten hectare Visulahti lease. Although it also describes an agreement as entered into, it says the parties would sign after the appeal period. Subsequent execution and current registered lease title are therefore not established by this announcement.

Source

Reviewed mik authority permit context

Source report

Mikkeli’s February 17, 2026 committee minutes describe Compute Nordic Finland’s Visulahti project as having received a construction permit, with a historical maximum of 200 MW, separately from FCDC. The MW basis and original permit conditions are not specified. This authority reported scope does not replace September’s 165 MW IT contract plan.
