Summary

Nebius Group is constructing a 310-megawatt AI data center in Lappeenranta, Finland, near the Russian border, with an estimated value exceeding $10 billion. This facility, already under construction by Finnish developer Polarnode, is slated for a phased launch beginning in 2027 and is projected to be among Europe's largest AI data centers. The center will support AI model training and application execution for multiple clients, not just one. Nebius selected Finland due to its favorable low energy prices, abundant renewable power sources, and naturally cool climate, which collectively reduce operational cooling expenses. This project represents Nebius's largest site outside the United States and is expected to contribute approximately 10 percent of the company's total planned capacity.

Key takeaway

For CTOs evaluating global AI infrastructure expansion, your strategy should prioritize regions offering low-cost, renewable energy and natural cooling advantages, such as Finland. This approach can significantly reduce operational expenditures for large-scale AI compute, making locations like Lappeenranta highly attractive for future data center investments.
