We are assisting Verne Global Ltd, the leading provider of sustainably powered HPC data centres in the Nordics, in developing a data centre in Mäntsälä, Finland. We advised Verne in acquiring the real estate company managing the Mäntsälä site, as well as in the subsequent acquisition of the site itself. Our assistance extends beyond real estate transactions to include permitting and tax-related matters. Additionally, we advise Verne on grid connection and electricity supply matters. The acquisition of the project site in Mäntsälä marks Verne’s fourth data centre in Finland, reinforcing its position as a leader in sustainable and scalable data centre solutions. The Mäntsälä campus, spanning 10 hectares and located just a 40-minute drive from Helsinki-Vantaa International Airport, will initially offer a capacity of 70 MW. The facility is designed to support data-intensive enterprises and AI innovators running HPC, machine learning, and other high-intensity workloads, all while operating exclusively on renewable energy. Verne’s new facility will adhere to the company’s best practice design principles, focusing on maximizing efficiency and minimizing environmental impact. The campus will be powered entirely by renewable energy sources, and waste heat generated by the data center will be utilized for local community heating projects. The company is working closely with the Mäntsälä Municipality to ensure the new facility benefits the local area, including plans to harness waste heat for district heating. Construction of Verne’s Mäntsälä data centre is set to begin in mid-2025 and is expected to take two years to complete. This expansion is a strategic move in Verne’s long-term plan to build out its sustainably powered data centre platform, which was acquired by Ardian, a world-leading private investment house, in early 2024. Ardian has already invested over EUR 1.6 billion in the Nordics, focusing on energy transition and digital infrastructure projects, and is working with Verne to drive sustainable growth across the region.  Read Verne Global’s press release.
