Summary: Google will invest €13 billion in digital infrastructure, energy projects and partnerships across Finland in 2027 and 2028. A long-term power agreement will help Fortum keep the Loviisa nuclear plant operating through 2050, while wind generation and battery storage are intended to support growing electricity demand.
The expansion covers Hamina, Kajaani, Muhos and Vaala. Google calls it its largest single investment in Europe. The data centres will support not only Gemini but also services such as Search and Maps; Google did not disclose installed compute capacity, server numbers or their future electricity demand.
Up to half of Loviisa's capacity
Google and Fortum have signed a 22-year power purchase agreement. It starts at a smaller level in 2028 and is set to cover up to 50% of the plant's capacity from 2030 through 2049. Loviisa's two reactors provide 507 MW each and generate about eight terawatt-hours per year, according to Fortum — roughly 10% of Finland's electricity.
Fortum is investing about €1 billion in life extension and modernisation work through 2050. Around €700 million of that programme had not yet received final investment decisions. The Google contract is intended to provide the revenue certainty needed to proceed and enable another 10 MW uprate in addition to a planned 38 MW increase. The contracted electricity price remains confidential.
The wider package includes contracts supporting a total of 629 MW of new onshore wind generation and a 94 MW battery system near Google's planned Kajaani site. The battery is expected to begin operating in late 2027 and help balance fluctuations. Google and Fortum will also explore new nuclear, renewable and flexibility projects; this is currently a memorandum of understanding, not a construction decision.
Pandorex Analysis
The unusual element is not only the investment figure but the structure: a hyperscaler is using long-term demand to underpin an existing nuclear plant while adding wind and storage. That can provide predictable low-carbon baseload, with the battery responding to short-term grid fluctuations. It does not prove that Google's Finnish data centres will run exclusively on these assets every hour.
Two large figures also need context. The €13 billion covers more than AI servers alone. Google's projected €520 million in savings for electricity consumers comes from a model comparing a hypothetical 1 GW of additional northern demand with the same load in southern Finland; it is not the confirmed size of this project. The economic effect of the power agreement is more concrete: part of the plant operator's price and investment risk shifts to a long-term industrial customer.
