What happened: Singapore-based DayOne will invest in a flagship hyper-scale campus
DayOne, a Singapore-based data-centre developer and operator, has announced plans for a flagship hyperscale data-centre campus in Lahti, Finland, with an aggregated investment of about $1.31 billion.
The project will redevelop a 1.06 million-square-foot former industrial site in Lahti’s Kiveriö district into a high-performance digital campus. Total planned IT load capacity is 128 MW, with the first phase delivering 50 MW. Site demolition is expected to begin in Q3 2025, with operations targeted for 2027.
The facility’s design centres on sustainability: targeting LEED Gold or higher, harnessing Finland’s naturally cool climate for free-cooling, avoiding freshwater cooling by using air-cool chillers, and exploring integration of waste-heat recovery into Lahti’s district heating system.
DayOne has signed a Growth Partnership Agreement with the City of Lahti, Lahti Region Development (LADEC), Lahti Energy, and LUT Universities. As part of this, it is committing $2.73 million to LUT Universities to fund research and development, student internships, faculty collaborations, and innovation. The project is expected to create 100 direct skilled jobs and about 1,000 construction roles at peak build-out.

Why it’s important
This move marks DayOne’s entry into Europe’s hyperscale market, using Finland’s renewable-heavy energy grid, cold climate, and pro-sustainability policies to build low-carbon digital infrastructure.
By converting an old industrial site into a modern data hub, DayOne aligns with Lahti’s ambition to be a carbon-neutral city—Lahti was named European Green Capital in 2021. The waste-heat recovery plan further connects the facility to local energy resilience.
The $2.73 million university partnership signals a human-capital investment alongside infrastructure growth, ensuring skilled talent and applied research flow into Finland’s expanding data-centre sector. This project also underlines Finland’s rise as a strategic Nordic location for AI, cloud, and high-capacity data workloads, appealing to global tech investors seeking sustainable operations.
