DATA AND AI INFRASTRUCTURE

DayOne, a Singapore-based data center developer, has announced plans for a data center in Klaukkala, Nurmijärvi, Finland, with preliminary site sale negotiations underway with the municipality. This project is part of DayOne's commitment to enhance Finland's digital ecosystem, following a €1.2 billion investment in Lahti and a joint venture in Kouvola.

The data center aims for a phased development potential of up to 560 MW of grid power, with construction expected to employ around 1,000 workers and long-term operations creating up to 700 skilled jobs. DayOne has partnered with Fortum for site development support and zoning assistance.

The project requires government approvals, including a permit from the Ministry of Defence. DayOne is also planning educational and environmental initiatives in collaboration with local institutions. Recent financing includes €1 billion from Brookfield and over US$ 2 billion in Series C equity to support expansion in Finland and Europe.
