French AI infrastructure firm Sesterce plans to invest $10 billion in an AI data center campus at the former Kaipola paper mill in Jämsä, Finland.
Construction is expected to begin this year, with capacity starting at 200MW before expanding to 600MW. Sesterce aims to develop more than 1GW of capacity in Finland long term. The company also pledged to enable 1MW of new renewable generation on Finland’s grid for every megawatt the campus consumes within 10 years of operations beginning.

"For more than six decades, the Kaipola mill produced paper for the world. Now, a new generation of industry is being planned for the site. Our goal is to preserve the area's industrial identity while making use of existing infrastructure, including the power grid, water systems, buildings, and logistics connections," said Youssef El Manssouri, CEO of Sesterce.

"Our planning is based on energy-efficient and flexible operations. The Sesterce Campus projects will use liquid cooling, deliver high energy efficiency, and feature controllable and flexible power consumption. Opportunities for utilizing waste heat are also being considered as part of the design.”

“The Sesterce project is an interesting opportunity to strengthen the vitality of the region, provided it progresses from plans to implementation and meets the applicable requirements. The redevelopment of the Kaipola site would be a welcome opportunity to give the area a new lease on life and support job creation in Jämsä. The City wants to advance investment projects in cooperation with businesses and will assess each project carefully as it moves forward.”GettyImages-2238556445.width-358.webp
