Google is investing EUR 150 million to double the size of its data center located in a former paper mill in the southeastern coastal town of Hamina in Finland. According to Google, the project includes the renovation of a second server hall and the restauration of a building facade designed by Alvar Aalto, Finland's most renowned architect.
The work is expected to take 18 months to complete and will create work for about 500 engineers and construction workers. When ready, the second server hall will add about 25 jobs to the center's current staff of 90.
Google bought the 60-year-old paper mill building from the Finnish company Stora Enso in 2009. Google invested EUR 200 million to turn it into a data center that uses water from the Baltic Sea for its cooling system, making it one of the most energy-efficient data centers in the world. The new server hall will also utilise the same seawater cooling system.
The data center began its operations in September 2011 and has been serving Google's customers in Europe and beyond. Google cites increased demand for online access to video and data as the reasons for expanding the facility.
