On November 11, 2025, Google announced an expansion of its Hanau site as part of a Germany-wide €5.5 billion investment programme through 2029. The announcement does not allocate that national investment total to Hanau or disclose a Hanau-specific expansion capacity or opening date. Google opened its Hanau data center in 2023 after a prior 2022 target. The four-story, 10,000-square-metre facility supports the Frankfurt cloud region; Google has not disclosed a site capacity.
