The facility, set to come online in the Bavarian town of Amberg in mid-2027, could eventually expand to 120 MW, the company told Reuters.
AI data centres in Germany boasted total capacity of 530 MW at the end of last year, according to figures from German lobby group Bitkom. Much of that, however, was operated by non-German providers.
European countries are pushing for more sovereign control over data and the infrastructure required for AI due to global tensions – from tariffs to armed conflict – as well as sharply diverging rules around online content.
First stage costs in triple digit million euro range
The plans for what would be one of Germany’s largest data centres have not been previously reported. Large technology companies like Google and Amazon’s AWS typically run data centres of around 100 MW or more.
Polarise, which operates 13 data centres in Germany and abroad, declined to give details on the size of the required investment.
“The final investment volume depends heavily on how many customers install their own servers or rent computing power,” said Marc Gazivoda, Polarise’s marketing director, adding that it did not receive state subsidies and investments could vary.
A source close to the company said the first stage of the project would cost in the “triple-digit million euro range”, which includes the main infrastructure but not the chips themselves. The final cost would depend on the number of chips required and their specific types, the source said.
A 12-MW data centre opened by Polarise in Munich last month cost 1 billion euros ($1.16 billion), according to an estimate by Deutsche Telekom. That facility already doubled Germany’s existing locally-operated capacity.
With oil prices shooting above $100 per barrel, the cost of energy for power-hungry data centres is increasingly in focus.
Polarise said its partner WV Energie will install a wind and solar power plant for the centre as well as batteries for temporary storage of electricity.
