$NBIS to Build a New 310 MW Data Center in Lappeenranta, Finland

First capacity expected to come online in 2027
Once fully deployed, it is set to be one of Europe’s largest dedicated AI factories and will support Nebius’s broader goal of securing more than 3 GW of contracted power by the end of 2026
The project follows the recent expansion of Nebius’s Mäntsälä data center to 75 MW, and adds to its wider EMEA footprint, which already includes more than 750 MW of contracted power across its own sites and colocations, plus a separate 240 MW AI factory under development near Lille, France
Arkady Volozh, founder and CEO of Nebius, said:
“We have been building in Finland for many years and are pleased to be expanding our presence here. Lappeenranta represents a significant addition to our global AI infrastructure build-out, and will make a significant contribution to achieving our capacity goals.”
$NBIS said its AI factories will serve customers with the latest NVIDIA Blackwell and Rubin systems. It also highlighted that its Mäntsälä site already houses Europe’s first operational deployment of the NVIDIA GB300 NVL72 platform, and that it intends to offer the NVIDIA Vera Rubin NVL72 platform later this year
The Lappeenranta site will be a multi-building campus on roughly 100 acres, and Nebius expects it to generate major local economic benefits. The construction phase is expected to create up to 700 skilled construction jobs, mostly sourced from the local area, with around 100 permanent positions once the facility is operational, plus hundreds of indirect jobs tied to operations and maintenance
City of Lappeenranta Mayor Tuomo Sallinen welcomed the announcement:
“Lappeenranta offers an increasingly attractive environment for innovation, with our universities playing a key role in developing top talent tailored to the needs of high-tech industries. The new data center will position our city at the forefront of Finland’s AI ecosystem and help meet Europe’s growing demand for artificial intelligence for decades to come. We’re proud that this project is being realized in Lappeenranta and in Finland, built sustainably on clean energy and driven largely by Finnish expertise.”
Nebius also said it is exploring partnerships with local academic institutions through Nebius Academy to help train AI talent, strengthen the local pipeline, and support long-term innovation in the region. On the sustainability side, the company said the Lappeenranta AI factory will use closed-loop liquid cooling, minimizing water use, and will be designed to integrate a heat recovery system that could donate excess server heat to the local district heating network. Nebius added that a similar approach in Mäntsälä avoided around 4,000 tonnes of CO2e emissions in 2025 and reduced heating costs for connected households by roughly 10%
