Hamina, Finland

From paper mill to data center

In March 2009, we purchased the Summa Mill from Finnish paper company Stora Enso and outlined our plans to convert the 60 year old paper mill into a data center. After investing an initial €200 million, we completed the first phase of the project in September 2011. More than 2,000 individuals working for 50 companies (mostly Finnish and from the local area) contributed to the project.

In August 2012, we announced an additional €150 million investment in Phase II of the data center, which will involve the restoration and conversion of an Alvar Aalto-designed machine hall. We expect the conversion to last approximately 18 months and to provide work for approximately 500 engineers and construction workers.

The facility is one of the most advanced and efficient data centers in the Google fleet. Our high-tech cooling system, which uses sea water from the Bay of Finland, reduces energy use and is the first of its kind anywhere in the world.

On this site, you can meet some of our employees or visit the Hamina data center photo gallery. We greatly appreciate the welcome we’ve had here, and we’re honoured to be part of the local community.

Why did Google choose Hamina?

Hamina has the right combination of energy infrastructure, developable land and available workforce for the data center. We had the unique opportunity to salvage an old paper mill in Hamina and use the pre-existing infrastructure to build a data center there.
