Google disclosed plans to invest a further EUR 450 million to expand its data center in Hamina, Finland.
In 2009, Google acquired an abandoned paper mill on the Bay of Finland, investing an initial EUR 200 million to launch Phase I of the data center. The facility takes advantage of the naturally chilly sea water for cooling. In August 2012, Google announced an additional EUR 150 million investment in Phase II of the data center.
