“The demand for Google services is growing daily and we are building our data center infrastructure to match this demand,” Google’s Finland country head Antti Jarvine said in a statement.
The new data centre will add to Google’s existing facility in the Finnish town, bringing its total investment in the area to €1.4bn ($1.56bn).
In 2009, Google invested €800mn ($895bn) to convert an old paper mill which was previously owned by Finnish firm, Stora Enso, into a data centre.
This existing data centre features an advanced cooling system that uses seawater from the Bay of Finland to reduce energy use.
Google currently has 58 data centres across the globe, with its European data centres being located in countries including Ireland, the Netherlands and Belgium.
