Chief Executive Sundar Pichai said the investment plan includes an additional 600 million euros investment in the Hamina data centre in Finland, bringing total investment in the site to two billion euros.
Finland’s Prime Minister Antti Rinne told the joint news conference that the announcement was fantastic news for Finland.
Google already has one data centre in Hamina, where it invested 800 million euros to convert an old paper mill. It said in May it would invest 600 million euros in a new data centre on the same site.
Google bought the site from paper firm Stora Enso in 2009. The location is close to the Russian border and uses seawater from the Gulf of Finland to reduce the energy used in cooling.
Google’s other European data centres are in the Netherlands, Ireland and Belgium.
The construction of the new data centres will mean that much of Google’s EU data will not have to go to the United States – something that complicates things under GDPR.
