Singapore-based data centre developer DayOne has announced a €1.2 billion investment in a hyperscale data centre campus in Lahti, Finland. This significant move marks DayOne’s expansion into Europe and underscores its commitment to enhancing Finland’s digital infrastructure. The project, set to transform a former industrial site in Kiveriö, will commence with site demolition in Q3 2025 and is expected to be operational by 2027.
The Lahti data centre will span 98,901 square metres and is designed to support a total potential capacity of 128 megawatts IT load. The first phase will include a building with a 50MW IT load. DayOne is currently in negotiations with potential tenants, although no agreements have been finalised. The facility aims for LEED Gold certification and will utilise Finland’s cool climate for energy-efficient operations.
DayOne has partnered with Lahti Energy to enhance local energy grid resilience and is exploring waste heat reuse to integrate the data centre into the local district heating system. This initiative aligns with Lahti’s sustainability goals and aims to contribute to the city’s carbon neutrality efforts.
Jamie Khoo, CEO of DayOne, highlighted Finland’s strategic advantages, including its reliable energy infrastructure and skilled workforce. “Finland offers unique advantages that align perfectly with our commitment to sustainable digital infrastructure,” Khoo stated.
The project is expected to create 100 skilled jobs and employ 1,000 construction workers at its peak. Additionally, DayOne has entered into a Growth Partnership Agreement with the City of Lahti and local institutions, committing €2.5 million ($___) to LUT Universities to foster regional cooperation and talent development.
