Nebius to triple capacity at Finland data center to 75 MW

Amsterdam, October 8, 2024 – Nebius (NASDAQ:NBIS), a leading AI infrastructure company, today announced that it will triple the capacity of its data center in Mäntsälä, Finland. The current expansion phase will enable Nebius to place up to 60,000 GPUs at the Mäntsälä location alone, with annual revenue potential of over USD 1 billion at full capacity utilization.

The expansion of the Finnish data center – a state-of-the-art location with strong green credentials – is part of Nebius’s program to invest more than USD 1 billion in AI infrastructure in Europe by mid-2025. The program also includes investments in build-to-suit data centers at greenfield sites primarily in Europe as well as colocations, such as the recently announced GPU cluster in Paris.

Andrey Korolenko, Head of Infrastructure at Nebius, said:

“Tripling capacity at our flagship site in Finland is an important step in our build-out of best-in-class AI infrastructure in Europe. Our data center at Mäntsälä is our ‘home base’ and showcases our ambition and the technical capabilities of the Nebius team, as well as our approach to adopting sustainability principles in our infrastructure. The capacity we are adding here during this expansion phase will enable us to better serve growing demand from AI builders globally.”

Nebius is already one of the leading providers of GPU capacity in Europe through the Mäntsälä data center. The expansion in Finland will include deployment of , which will be available to customers from November, in addition to already installed that form the backbone of Nebius’s fleet of NVIDIA GPUs. Nebius will also be one of the first providers in Europe to bring the state-of-the-art, energy-efficient platform to customers in 2025.

The data center at Mäntsälä deploys innovative technological solutions that help to reduce its environmental footprint, reflecting Nebius’s approach to adopting sustainability principles in its infrastructure. These include hardware optimized for intensive workloads, energy-efficient supercomputing, advanced cooling and heat recovery systems.

With a power usage effectiveness (PUE) as low as 1.1 under high IT loads, the data center significantly outperforms the global average of 1.58. It also utilizes free cooling, reducing reliance on chillers and refrigerants, and incorporates a heat recovery system to repurpose server heat for local residential heating. This system currently recovers approximately 20,000 MWh of energy annually, heating the equivalent of 2,500 Finnish homes. Expansion of the data center will further increase the efficiency of the heat recovery program.

The Mäntsälä data center is also home to ISEG, among the most powerful supercomputers worldwide in both performance and energy efficiency. With 35.26 GFlops per watt-second, it ranks in the top 25 supercomputers by energy efficiency globally. The facility’s innovative design allows for operations at higher server temperatures, up to 40°C, contributing additional energy savings of approximately 15%.

Nebius is being purpose-built to meet the demands of the global AI industry and leans on deep technical expertise across hardware, software and machine learning. The company’s 500+ strong team of engineers has decades of knowledge of building world-class tech infrastructure, as well as an in-house LLM R&D team.

The current investment program will enable Nebius to reach a total capacity of tens of thousands of NVIDIA GPUs to bring its highly differentiated, energy-efficient, complete AI cloud offering to customers worldwide.
