German start-up Polarise announced plans to build a 30-megawatt AI data centre in Bavaria by mid-2027, potentially doubling Germany's domestically-run computing capacity. The facility addresses European efforts to gain sovereign control over critical tech infrastructure amid global tensions. With costs in the triple-digit million euro range and renewable energy integration, the project highlights the strategic push for technological independence.

German Start-Up Polarise Targets Sovereign AI Infrastructure

German start-up Polarise has unveiled plans to construct a 30-megawatt AI data centre in Amberg, Bavaria, marking a significant step in European efforts to establish sovereign control over critical technological infrastructure. Set to come online by mid-2027, the facility would effectively double Germany's domestically-run AI computing capacity, addressing growing concerns about technological dependence on foreign providers

According to figures from German lobby group Bitkom, AI data centres in Germany boasted total capacity of 530 MW at the end of last year. However, much of that capacity was operated by non-German providers, underscoring the strategic importance of Polarise's initiative

. The new facility could eventually expand to 120 MW, positioning it among Germany's largest data centres, though still smaller than the typical 100 MW or more facilities operated by tech giants like Google and AWS.

Investment Volume and Financial Considerations

The first stage of the project will require investment in the "triple-digit million euro range," according to a source close to the company. This figure covers the main infrastructure but excludes the chips themselves, with final costs depending on the number and types of chips required

. Marc Gazivoda, Polarise's marketing director, explained that "the final investment volume depends heavily on how many customers install their own servers or rent computing power." Notably, the company confirmed it did not receive state subsidies for the project.

To contextualize the scale, a 12-MW data centre opened by Polarise in Munich last month reportedly cost 1 billion euros ($1.16 billion), according to an estimate by Deutsche Telekom. That facility already doubled Germany's existing locally-operated capacity, demonstrating the company's rapid expansion trajectory

. Polarise currently operates 13 data centres across Germany and abroad.

Renewable Energy Sources Address Power Demands

With oil prices surging above $100 per barrel, energy costs for power-hungry data centres have become a critical concern. Polarise has partnered with WV Energie to address this challenge through renewable energy sources. The partnership will install a wind and solar plant dedicated to the centre, complemented by battery storage for temporary electricity storage

. This approach not only addresses cost concerns but aligns with broader sustainability goals as AI infrastructure expands across Europe.

Strategic Implications for European Tech Independence

The Amberg, Bavaria facility represents more than infrastructure expansion—it signals a strategic shift in how European nations approach computing power and data sovereignty. As global supply chains face disruption and geopolitical tensions intensify, control over critical technological infrastructure has emerged as a national security priority. The project positions Germany to reduce dependence on foreign providers while building domestic capacity to support AI development and deployment. Industry observers will be watching whether other European nations follow similar paths, potentially reshaping the continent's tech infrastructure landscape over the coming years.
