We are assisting Verne Global Ltd, the leading provider of sustainably powered HPC data centers in the Nordics, in developing a data center 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 center in Finland, reinforcing its position as a leader in sustainable and scalable data center 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 center 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 center 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.

We are assisting Verne Global Ltd, the leading provider of sustainably powered HPC data centers in the Nordics, in expanding a data center in Helsinki region, Finland. In the autumn of 2024, we acted as Verne’s advisor in acquiring the land at its existing Helsinki data center campus, securing room for future expansion. In addition to real estate development, our advice covers permitting and construction related legal matters. The expansion marks another milestone in Verne’s ambitious growth strategy for the Nordics, following the recent announcement of its new facility to be built in Mäntsälä, Finland. The land was acquired from Onvest, a family-owned company with a long history in the region. The site’s strategic location provides excellent connectivity to power and fibre networks, proximity to Helsinki Airport, and easy access to the city centre – making it ideal for organisations across industries looking for reliable, accessible, and well-connected facilities. Verne plans to develop the site further, leveraging its 70MW capacity to meet the increasing demand for sustainable, high-performance compute infrastructure. Designed with high-density compute in mind, the planned expansion will include two new buildings fully equipped to meet the technical requirements of AI, HPC, and other intensive workloads. Verne remains committed to sustainability, with the Helsinki campus running on 100% renewable energy. Waste heat generated by the data center is repurposed through a direct connection to the local district heating network. All new facilities will be built to support liquid cooling, enabling efficient management of the high heat levels generated by AI and other intensive compute workloads. Additionally, Verne uses renewable diesel for its backup power generators in Finland, reducing greenhouse gas emissions from the generators by an average of 90%.

We acted as the Finnish legal advisor for BHP in connection with an exploration alliance agreement entered into between BHP and Kingsrose Mining Limited under which BHP (through a wholly owned subsidiary) will provide funding for regional mineral exploration across areas of interest in Finland.
