BERLIN (Reuters) -Alphabet's Google will invest 5.5 billion euros ($6.41 billion) in Germany in the coming years in a push to expand its infrastructure and data centre capacity in Europe's largest economy, it said on Tuesday. The plan includes a new data centre in Dietzenbach, close to Frankfurt, Google said, according to information it provided ahead of a press conference in Berlin. An unnamed source told Reuters earlier on Tuesday that Google's investment plan also included the expansion of its site in the city of Hanau, also in the central German state of Hessen and close to Frankfurt. The news conference at 4:30 p.m. (1530 GMT) will include German Finance Minister Lars Klingbeil as well as senior European Google officials Marianne Janik and Philipp Justus. It is not clear whether the German government will subsidise Google's investment plan.
