Google — Hamina, Finland AI Data Center Campus

Google's Hamina data center in southeastern Finland is one of the company's most distinctive and well-known facilities worldwide. Built inside a converted paper mill on the Gulf of Finland, the Hamina campus uses a unique seawater cooling system that draws cold water directly from the Baltic Sea to cool its servers — eliminating the need for cooling towers and reducing freshwater consumption to near zero.

Opened in 2011, Hamina was Google's first data center in Northern Europe and helped establish Finland as a premier data center hub, a status that has grown substantially in the years since. The facility draws power from Finland's grid, which has a high renewable mix including hydropower, wind, and nuclear. The campus supports Google Cloud's europe-north1 region and contributes to Google's Northern European AI inference capacity.

The Hamina facility is powered in part by the nearby Hanhikivi nuclear power plant development and renewable energy contracts. Google has invested over €1 billion in the Hamina campus across successive expansion phases. The facility is a key example of Google's "moonshot" approach to data center sustainability, and has been featured prominently in environmental performance reports. The seawater cooling innovation at Hamina has influenced data center design globally.
