Pure DC plans 550MW AI data centre campus in Finland

Pure Data Centres Group has announced plans for a major AI infrastructure campus in Seinäjoki, Finland, capable of supporting more than 550MW of IT capacity.

The project, designated SJK01, is set within a 370-acre campus and could attract more than £6.3 billion (€7.5 billion) in total investment, subject to future approvals and contracting.

Pure DC said the first phase will deliver 110MW of capacity, representing more than £1.2 billion (€1.5 billion) of investment, marking it as one of SJK01 one of the largest AI infrastructure developments currently proposed in Europe.

Pure DC Confirms First Phase is Fully Leased

The first phase of SJK01 is already fully leased, giving the project a stronger delivery profile than earlier-stage data centre proposals still dependent on customer commitments.

Pure DC said planning permissions, power requirements, and the first substation for the initial data hall are already in place.

That combination is significant in a market where large-capacity announcements are becoming more common, but delivery depends heavily on secured power, permitting, and contracted demand.

Sjk01 Links Growth With Regional Development

Pure DC and local partner SDC Ventures plan to work with Seinäjoki Municipality on education, reskilling and local supply-chain initiatives.

The development is expected to support more than 3,000 jobs during its decade-long construction programme. The campus is also expected to contribute to local electricity and telecommunications infrastructure, while waste heat from the site is intended to be repurposed for district heating.

Pure DC said it will collaborate with Seinäjoki University of Applied Sciences and vocational institutions to support a long-term skills pipeline.

“We are not building data centres in Seinäjoki,” said Gary Wojtaszek, Executive Chairman and Interim CEO of Pure DC. “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.”

The local measures show how large AI infrastructure projects are being positioned within regional economic development, rather than being treated only as private data centre assets.

AI Infrastructure Reaches Campus Scale

The figures attached to SJK01 show how quickly AI infrastructure requirements are changing.

The completed campus could exceed 550MW of IT capacity and draw on more than 700MVA of renewable power. The design is based on repeatable 40MW AI-ready modules, using Direct Liquid Cooling to support high-density workloads.

Pure DC said both air-cooled and liquid-cooled configurations will use closed-loop systems with zero operational water consumption.

The scale of SJK01 places the project closer to long-term infrastructure development than a single data centre build. It also shows why access to power, modular delivery and local infrastructure planning are becoming central to Europe’s AI capacity pipeline.

Finland Adds Scale to Pure DC’s European Expansion

The Finland announcement follows Pure DC and SEGRO’s recent joint venture to develop a 48MW fully fitted hyperscale data centre in Paris. The two projects reflect different parts of Europe’s data centre market.

Paris offers power-secured capacity in a constrained metropolitan location close to major enterprise and cloud demand. Seinäjoki offers a larger development footprint, access to renewable power, and the ability to support AI infrastructure at campus scale.

The project positions Pure DC across both established European hubs and emerging large-scale AI infrastructure locations.

Europe’s AI Capacity Pipeline Grows Larger

Pure DC’s Seinäjoki campus adds another large-scale project to Europe’s AI infrastructure market.

The most important near-term detail is the fully leased 110MW first phase, because it links the announcement to committed demand rather than future capacity ambition alone.

The larger campus reflects the direction of AI infrastructure development in Europe: multi-phase sites planned around power availability, repeatable design, and long-term regional integration.

As AI workloads grow, projects like SJK01 suggest Europe’s next generation of data centre capacity will be shaped by where large amounts of power, land, customer demand, and local delivery capability can be brought together.
