Google has announced an additional €13 billion investment in Finland, Yle News reported on Tuesday. The company said the funding will be used to develop data centres and the supporting infrastructure they need, making it its biggest single investment in Europe to date.

The announcement is significant for Finland because large data centre projects depend on electricity, network capacity and other technical systems around the sites. It also underlines the country’s continued appeal for major international technology investments, according to the report.

Google has not yet given further details on where the projects will be located or when construction will begin. It is also unclear how the total sum will be divided between the data centres themselves and the infrastructure built to support them.
