Cloud computing company Nebius is building a 310-megawatt data center campus in Lappeenranta. Once completed, it will be one of Europe’s largest data centers dedicated to artificial intelligence computing. In the pre-construction phase currently underway in the Pajarila area, Polarnode’s main partner is Louhintahiekka Oy.

Louhintahiekka is responsible for all earthworks and pre-construction activities for the Lappeenranta data center campus.
The multi-billion-euro project is now progressing to its first construction phase, covering an area of approximately 8.5 hectares. Louhintahiekka is carrying out the project’s earthworks and pre-construction works in their entirety.
“Data center construction requires delivery reliability, precise schedule management, and the ability to execute large-scale projects quickly and safely. We currently have several infrastructure construction projects underway across Finland,” says Aapo Lahtinen, CEO of Louhintahiekka.
Polarnode is the developer of the project and is responsible for delivering the pre-construction phase to Nebius. The company has been involved in the development of the Lappeenranta data center project since its early stages.
“The pre-construction phase creates the foundation for the implementation of the entire data center campus, which is why seamless cooperation from the very beginning of the project is especially important to us. Louhintahiekka has joined the project with a determined and professional approach, reinforcing our view that Finland has strong expertise in the pre-construction of demanding data center projects,” says Lauri Ikonen, Chief Technology Officer at Polarnode.
The data center being built in Lappeenranta is part of Nebius’ strong international expansion in AI computing infrastructure. Once completed, the campus will be one of Europe’s largest AI-focused data centers.
The first phase of the project is scheduled for completion in 2027.
