We advised a leading global investment firm Brookfield, alongside a global sovereign wealth investor, on the Finnish law aspects of a EUR 1 billion holdco financing for DayOne Data Centers, a Singapore-headquartered developer and operator of hyperscale data centres. Structured as a seven-year secured holdco financing facility of €500 million, expandable to €1 billion – and secured by DayOne’s Finland platform – the financing will support the rollout of hyperscale developments in Lahti and Kouvola, providing nearly 300MW of planned capacity across Finland. The proceeds will also support DayOne’s global expansion across the EU and APAC, with flexibility to allocate to other key growth markets as required.

We are assisting the Municipality of Tuusula in the sale of land to funds managed by Blackstone, a global asset management company, for a data centre project. Currently, a preliminary agreement has been signed for the sale of the approximately 16.7 hectare site in Jokela, Tuusula. In October 2025, the Municipal Council of Tuusula approved zoning amendments that enable the construction of a data centre campus in the Vallunlenkki zoning area. The preliminary agreement on the sale of the land and the approval of the zoning are the first steps in a process that would upon its implementation constitute a significant investment that supports employment and economic growth in Tuusula and its surroundings. The next phase, the environmental impact assessment, is planned to commence in early 2026. Blackstone owns QTS, one of the worlds’s fastest growing data centre platforms with more than 82 data centres in operation or under development across Europe and the United States.

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%.
