On October 8, 2026, French AI infrastructure company Sesterce announced plans for an AI campus on the site of the former Kaipola paper mill in Jämsä, Finland, with planned investment of over €10 billion. The first phase is 200 MW, with works planned to start in 2026, and capacity is expected to rise to 600 MW in a second phase.
