Pure DC has been developing the Seinäjoki project for at least a year, initially outlining plans for a 500MW site spanning 370 acres. In April 2026, the company purchased a 22.3-hectare plot of land from the city for €3.86 million ($4.55 million), with three data center buildings planned for the site. The company has since increased the planned capacity to 550MW and now expects to invest more than €7.5 billion ($8.55 billion) in the full buildout.
The project, designated SJK01, is expected to create around 3,000 construction jobs in the region, with construction work anticipated to run for a decade. The site will feature repeatable 40MW AI-ready modules equipped with direct-to-chip liquid cooling to support high-density workloads, reflecting the industry's broader shift toward infrastructure designed for artificial intelligence applications.
Jaakko Kiiskilä, mayor of Seinäjoki Municipality, said the partnership between the region and Pure DC has been forged over the past two years and described the project as a catalyst for regional development. "This project will bring major employment to the Seinäjoki area for years to come, and across many skills and trades," he said, adding that waste heat from the data center will be repurposed for the district heating network and that Pure DC will invest in education and reskilling initiatives.
Laura Davies, the British ambassador to Finland, described the development as 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 said.
The announcement comes as Pure DC continues to expand its global footprint. Founded in 2013 and owned by investment firm Oaktree Capital Management, the company has developments in London, Abu Dhabi, Riyadh, Madrid, Jakarta, Dublin, Amsterdam and Seinäjoki. Pure DC says it has more than 1GW of capacity live or under development. Earlier this year, the company secured $2.7 billion in financing to support its pipeline.
The Seinäjoki campus reflects a broader trend of hyperscale operators and developers racing to secure land, power and cooling capacity in the Nordics, where abundant renewable energy and cool climates offer advantages for energy-intensive AI workloads. Microsoft's reported participation signals continued demand for large-scale, liquid-cooled capacity in Europe even as the company and its peers reassess portions of their global data center pipelines.
