Nebius has said it intends to triple the capacity of its data centre in Mäntsälä, Finland to 75 MW.
The expansion will enable Nebius to place up to 60,000 GPUs at the Mäntsälä site, including the deployment of NVIDIA H200 Tensor Core GPUs, in addition to the already installed NVIDIA H100 Tensor Core GPUs.
The facility utilises free cooling and a heat recovery system to repurpose waste heat for local residential heating. This system currently recovers approximately 20,000 MWh of energy annually, heating the equivalent of 2,500 Finnish homes.
“Tripling capacity at our flagship site in Finland is an important step in our build-out of best-in-class AI infrastructure in Europe,” said Andrey Korolenko, Head of Infrastructure at Nebius.
“Our data centre 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’ expansion of its Finnish data centre is part of the company’s plans to invest USD 1 billion (£762.67 million) in AI infrastructure in Europe by mid-2025. This includes build-to-suit data centres at greenfield sites as well as colocations, such as the recently announced GPU cluster in Paris.
