French AI and supercomputing infrastructure company Sesterce has announced plans for a $10 billion AI data center campus in Jämsä, Finland, to be built on the site of the former Kaipola paper mill. Construction begins this year, with the first phase delivering 200MW and a second phase expanding capacity to 600MW; the company's long-term target for Finland exceeds 1GW. Sesterce has committed to enabling one megawatt of new renewable generation on the Finnish grid for every megawatt the campus consumes within 10 years of becoming operational, and will establish a $10 million community fund for local projects in Jämsä. The company says an anchor customer has already been secured for the site.

Why this matters

A $10 billion commitment from a single operator to build more than 600MW of AI-focused capacity in Finland signals growing investment in Nordic markets driven by access to power infrastructure and cooling resources. The renewable energy matching commitment, tied to a 10-year operational deadline, sets a specific contractual benchmark that other large campus developers may face pressure to adopt or respond to.
