atNorth plans a 75 MW first phase for Finland's FIN05 campus
What happened
Nordic data-center operator atNorth says it plans to develop FIN05 in Salo, Finland, starting with 75 megawatts of secured power and a wider development path of up to 230 megawatts.
What is actually proposed
atNorth says FIN05 would occupy 28.6 hectares in Salo, west of Helsinki. The company describes 75 megawatts of power for the first phase as secured and says the broader site has a path to as much as 230 megawatts through a Fingrid substation. Those figures describe planned facility power, not commissioned IT load or installed accelerator capacity.
The company estimates its own site investment at roughly €2 billion, excluding customer-owned servers and their installation. It says that customer equipment could represent up to another €10 billion. Both numbers are atNorth forecasts attached to a proposed development, not money already spent or independently verified construction costs.
How the campus would interact with the grid
atNorth plans long-term power-purchase agreements with local suppliers and says it will explore flexibility services for Finland's transmission system. In practice, flexible load can increase or reduce consumption in response to grid conditions, but the announcement does not specify the dispatch rules, duration or megawatts that FIN05 could make available.
The company also intends to study uses for the data center's rejected heat with local stakeholders. Heat reuse requires more than a warm-water outlet: a nearby customer, connecting pipes, compatible temperatures and workable seasonal economics must all line up. No heat buyer or delivery volume is named for Salo.
What has not happened yet
The announcement is a development plan, not a construction or operating milestone. It does not give a construction start, opening date, signed customer, building count, cooling design or first-phase IT capacity. It also does not publish the interconnection agreement or the schedule behind the stated path from 75 to 230 megawatts.
The next evidence to watch is a permitting and construction timetable, binding energy and customer agreements, equipment procurement and ultimately commissioned capacity. Until then, FIN05 is best understood as a powered development proposal with substantial expansion ambitions.
