Arcem has entered into an agreement to acquire an 800,000 sqm site to be used for a data center.
Bonum's platform for data center development, Arcem, has signed an agreement with Joroinen municipality in eastern Finland to acquire land for a data center project. The project has potential for 500 MW of power and development capacity. The first construction phase of 60 MW will be available as early as 2027, followed by a planned increase to 100 MW by 2029.
According to Arcem, the agreement was signed Thursday by unanimous decision in the Joroinen municipal council. The company has worked on developing the site for over a year through a reservation agreement with the municipality. The property is zoned for data center use, and the building permit for the first phase is expected to be in place as early as this summer.
Power Hub
The site is located directly adjacent to Fingrid's existing 400/110 kV transformer station at Huutokoski, a central hub in Finland's transmission grid. In addition to the land purchased from the municipality, Arcem has secured neighboring plots for future expansion. The total area is approximately 800,000 square meters.
"In Joroinen we have established a clear path to grid connection and construction start through a structured process with the municipality, the local grid company, and Fingrid. The area is reached in under three hours by car from Helsinki via four-lane motorway, has a railway at the site, and also a local airport within close proximity. This makes it attractive for a wide range of tenants," says Anders Bakken Eriksen, CEO of Arcem.
One of the Largest in the Nordics
The project, with a potential of over 500 MW, could become one of the largest data center campuses in the Nordics. Bonum writes in a statement that the scale is particularly relevant in a market where demand for AI and HPC capacity is rapidly increasing, while access to large sites, power, and feasible grid solutions has become a decisive competitive advantage.
The project is positioned for AI infrastructure, hyperscale customers, and regional clients with the need for storage on Nordic and European soil.
"In today's market, two things matter most: time to market and scale. Our project in Joroinen delivers both. This is one of several projects we are working on in Finland, and forms part of a broader Nordic platform we have built up over time," says Bakken Eriksen.
Finnish Execution Capacity
Arcem believes the Finnish approach to business development and industrial initiatives has been an important part of the rationale behind the venture. The process in Joroinen has been characterized by quick clarifications, close dialogue, and a high degree of cooperation between the municipality, the grid company, and other authorities.
"We have experienced Finland as highly professional, predictable, and solution-oriented. The municipal administration, local politicians, Fingrid, and other Finnish public actors have contributed to a cooperative climate that makes it possible to develop large industrial projects with both speed and quality. This deserves great recognition," says Anders Bakken Eriksen.
