DayOne Consolidates Finland Expansion With 560 MW Data Center Development

Why It Matters

The development taps Finland’s renewable‑energy advantage and fast‑growing data‑center market, boosting regional digital capacity and economic activity.

Key Takeaways

• 560 MW capacity planned in Nurmijärvi.
• Fortum to aid zoning and grid connection.
• Construction to employ ~1,000 workers.
• Operations to support ~700 skilled jobs.
• Finland data‑center market growing ~54% CAGR 2024‑2030.

Pulse Analysis

Finland has become a magnet for data‑center operators thanks to its cool climate, abundant renewable power and proactive government incentives. The country’s low‑temperature environment reduces cooling costs, while its strong grid and carbon‑free energy mix align with sustainability goals that many global tech firms now prioritize. Analysts predict the Finnish market will expand at a compound annual growth rate of roughly 54% through 2030, drawing heavyweight players such as Google and Microsoft and encouraging new entrants to capitalize on the favorable economics.

DayOne’s Nurmijärvi project illustrates how the Singapore‑based operator is leveraging this environment to accelerate its European expansion. Backed by a $2 billion Series C round and a $1.2 billion mezzanine facility, the company is able to pursue a phased build‑out that could reach 560 MW of grid power. The partnership with Fortum streamlines regulatory hurdles and ensures reliable grid access, a critical factor for hyperscale facilities. By targeting a 1,000‑person construction workforce and 700 permanent technical roles, DayOne also positions the development as a significant local economic catalyst.

The broader implication for the industry is a shift toward sustainable, high‑density sites in regions that combine climate advantages with renewable resources. DayOne’s aggressive financing strategy and collaborative approach with local utilities may set a template for other operators seeking to replicate Finland’s growth model across Europe. As demand for cloud services and AI workloads surges, data‑center capacity in green locations will likely become a competitive differentiator, driving further investment and innovation in the sector.

DayOne Consolidates Finland Expansion With 560 MW Data Center Development

DayOne, the Singapore‑headquartered data‑center operator with facilities across APAC, has unveiled early‑stage plans to develop a data‑center project in Nurmijärvi, about 30 km north of Helsinki, as it accelerates its European expansion. The announcement follows DayOne’s more than $2 billion Series C equity financing earlier this month.

The planned site in Klaukkala, the southernmost urban area of Nurmijärvi, is positioned to leverage Finland’s renewable‑energy resources and robust digital infrastructure. The project is subject to required government approvals and permits.

DayOne and Finnish energy producer Fortum have signed a site‑securing and development agreement under which Fortum will support zoning processes and facilitate grid‑connection planning.

With a phased development potential of up to 560 MW of total grid power, the project is expected to create a significant economic impact. At its peak, construction is expected to employ approximately 1,000 workers, while long‑term operations will support up to 700 skilled positions.

“The planned project further reinforces DayOne’s long‑term commitment to advancing Finland’s digital ecosystem,” the company said in a statement.

DayOne’s International Expansion Strategy

DayOne’s move into Finland builds on its previously announced investments in the country, including a $1.4 billion hyperscale development in Lahti and a joint‑venture project in Kouvola with a local partner.

The Lahti flagship, announced in August 2025, will transform a former industrial site into an advanced, high‑performance digital‑infrastructure facility spanning nearly 100,000 m². The first phase includes a 50 MW IT‑load building, with a total potential IT‑load capacity of 128 MW.

A Vision for the Future

DayOne’s rapid expansion is supported by substantial financial backing. In addition to the $2 billion Series C equity financing announced in January 2026, the company secured a mezzanine financing facility of up to $1.2 billion in December 2025 from Brookfield and a global sovereign investor. These funds are fueling DayOne’s growth in Finland and Europe.

As the data‑center market expands, DayOne’s investments in Finland signal a broader trend among operators seeking sustainable, high‑performance infrastructure in emerging European markets.
