Pure Data Centres Group (Pure DC) has launched one of Europe’s largest AI infrastructure projects in Finland and the largest-ever by a UK company.

Designated SJK01, Capacity Magazine’s data centre of the month for June this year, the full campus is set within 370 acres and targeted to support over 550MW of IT capacity for mass-scale AI and machine learning workloads.

The data centre operator said Phase 1 will see an investment of over €1.5 billion (US$1.71 billion) for an 110MW AI campus. The site, located in Seinäjoki, is capable of scaling to a +€7.5 billion ($8.56 billion), 550MW+ campus for AI workloads, subject to the necessary permissions and contracting.

At this figure, the full Seinäjoki campus will be one of the largest AI infrastructure projects in Europe and will help put Finland at the forefront of Europe’s AI transition.

“Countries building AI infrastructure over the next decade will shape the global economy for the next fifty years. Finland has all the ingredients required to lead this transformation – world-class engineering talent, abundant renewable energy and a culture of innovation that gave rise to Nokia”, explained Gary Wojtaszek, executive chairman & interim CEO of Pure DC.

He added: “We are not building data centres in Seinäjoki. Together with our partners, including the Seinäjoki Municipality, we are helping create one of Europe’s most important AI ecosystems capable of supporting global tech leaders as well as the next generation of Finnish entrepreneurs and innovators.”

Phase 1 of the site is already fully leased, with the substation for the first data hall constructed and live, Pure DC said, and all planning permissions and power requirements are secured.

It will have the capacity to play a pivotal role in supporting Finland’s reskilling education, entrepreneurship, digital growth and energy resilience. In collaboration with Pure DC’s local partner, SDC Ventures, the development is expected to provide over 3,000 jobs during the decade-long construction, driving demand for skilled roles and utilising local companies wherever possible. The project will also improve local electricity and telecommunications infrastructure, Pure DC said.

“Our partnership will see Pure DC investing across several education and reskilling initiatives,” said Jaakko Kiiskilä, Mayor of Seinäjoki Municipality. “Our joint belief is that this campus can be a catalyst for the creation of an even larger ecosystem of entrepreneurs, supply chain industries, and employment for residents.”

With access to more than 700MVA of renewable power, the campus benefits from low energy costs and a highly stable grid. The development strategy is based on repeatable 40MW ‘AI-ready’ modules, Pure DC explained, built with Direct Liquid Cooling (DLC) to support the high-density thermal demands of next-generation hardware.

Pure DC is also working with local communities near its current and future locations. In Seinäjoki, this includes developing a long-term skills pipeline through collaboration with Seinäjoki University of Applied Sciences and vocational institutions. It aims to provide specialist skills training with a path to immediate post-qualification employment, helping to reskill an area of Finland traditionally associated with forestry and paper-milling. SJK01 is also expected to deploy waste-heat management, enabling district heating programmes.

The British Ambassador to Finland, Laura Davies, commented: “I am delighted by this major UK investment into Pure DC’s new site in Seinäjoki – the largest yet by a UK company in Finland. It’s an example of the growing role of UK companies in financing and delivering digital infrastructure across Europe, which is a key component of building our shared data sovereignty.”

She added: “Not only will this AI data centre campus become one of Finland’s largest inward investment projects, but it will be a critical enabler of scientific excellence and provide a platform to develop industrial competitiveness and sovereign capability.”
