Sources had disclosed to Reuters on Thursday that Google Inc would be increasing its investment in its data center located in eastern Finland. The search engine company already poured an initial EUR200 million or USD275.65 million investment and another EUR150 million on August 12.

The Hamina data center had been using a sea water cooling system. The cooling system was part of an old paper mill formerly owned by Stora Enso. Google bought the asset from the Finnish paper company in 2009.

Sources said Google would be announcing the company's next investment round sometime in November. However, sources where not clear about the size of the investment. Reuters speculated that the announcement would be made on November 4, as a government official confirmed that Prime Minister Jyrki Katinen would be attending an event happening in Hamina on that date.

Northern European countries, including Finland, had been the go-to sites of companes to install data centers to reduce costs incurred in cooling data centers.
