A French AI Plan Takes Shape in Central Finland
France’s Sesterce plans a data center site in Finland that will cost more than €10 billion. The project will take shape in Jamsa, central Finland, with work planned to start in 2026. Its first phase will provide 200 megawatts of capacity, according to the company.
From there, Sesterce expects the site’s capacity to reach 600 megawatts during its second phase. The project adds another major foreign technology investment to Finland’s recent development activity. Sesterce also has an anchor customer for the planned site, according to its statement.
Jamsa Site Gives Sesterce Room to Scale AI Power
The Jamsa site gives Sesterce a location for its planned AI infrastructure project in central Finland. The facility will occupy a former paper mill site that closed in 2021. Sesterce said the project already has an anchor customer for its planned data center.
The first phase will provide 200 megawatts of capacity once work begins. Sesterce plans to start work on that initial phase in 2026. The project’s scale will then expand substantially under the second phase. That phase is expected to raise total capacity to 600 megawatts.
The planned expansion gives the Jamsa site a clear capacity path beyond its initial phase. The 200 megawatt first phase represents the project’s starting capacity at the former mill site. Sesterce has already identified an anchor customer for the project. That customer provides an established commercial commitment for the planned facility.
Jamsa therefore forms the initial site for Sesterce’s broader AI infrastructure plans in Finland. The company intends to expand capacity there after the first phase reaches its planned scale. Its stated second phase target would bring the site to 600 megawatts. This expansion remains part of Sesterce’s larger ambition for AI capacity across Finland.
A Former Paper Mill Could Power a Larger AI Push
Beyond the Jamsa project, Sesterce has set a broader capacity goal for AI infrastructure across Finland. The company aims to establish more than 1 gigawatt of AI capacity over the longer term. That target extends beyond the current site and its planned 600 megawatts of capacity.
Sesterce plans to use existing industrial sites for additional AI capacity across Finland. The company said its approach will align future capacity with market demand. This strategy places the Jamsa project within a wider Finnish infrastructure plan. The broader goal also exceeds the capacity planned for the current site.
The company’s longer term target would put more than 1 gigawatt of AI capacity across Finland. Sesterce has not limited that ambition to a single location or facility. Instead, it plans to use existing industrial sites as opportunities arise. Market demand will determine how Sesterce develops capacity across those locations.
That approach gives the company’s Finnish plans a broader scope beyond the Jamsa facility. The current project establishes one site, while future sites could contribute additional capacity. Sesterce’s stated target remains more than 1 gigawatt of AI capacity across Finland. The company expects market demand to guide that longer term development.
Sesterce’s Finland Ambition Extends Beyond One Site
Taken together, Sesterce’s plans represent a more than €10 billion investment in Finland. The Jamsa project will begin with 200 megawatts before a second phase reaches 600 megawatts. The former paper mill site therefore provides the foundation for Sesterce’s broader Finnish AI capacity plans.
Beyond Jamsa, Sesterce aims to establish more than 1 gigawatt of AI capacity across Finland. The company plans to use existing industrial sites and align future capacity with market demand. Its stated plans therefore extend from one major project toward a wider national infrastructure ambition.
