maincubes, the largest German data center provider, today celebrated the groundbreaking ceremony for its next major project in Schwalbach: the FRA03 data center, which will become a new benchmark for sustainable digital infrastructure in Germany. At the same time, the company is advancing construction of BER02, its strategic campus in Berlin, designed to meet the explosive demand for cloud services, AI, and high-performance computing (HPC) in Europe.
FRA03: Sustainability, Capacity, and Cutting-Edge Technology
The new FRA03 facility, set to open in the summer of 2026, will offer a total power capacity of 16 megawatts (MW) dedicated to IT services. The center has been designed from the ground up with the highest standards of efficiency and sustainability: it will be powered entirely by renewable energy, thanks to a strategic agreement with Stadtwerke Göttingen, and will utilize waste heat to supply the local district heating network, establishing itself as a pioneering model of integration between technology and the urban environment.
The ceremony, held at the Schwalbach site, was attended by municipal and industry representatives who highlighted institutional collaboration as key to the project’s success. maincubes expressed its gratitude to all industry, political, and technical partners who made the development of FRA03 possible and announced its intention to continue expanding the capacity of its data centers in the Frankfurt and Berlin regions, with plans to add nearly 200 MW in the coming years.
BER02: The New Cloud & AI Campus Reference in Berlin
The next major step for maincubes is BER02, the first data center of a 144 MW campus designed for large-scale AI, cloud, and technology company deployments in Berlin. BER02 is located on the outskirts of the German capital, a strategic location that will provide geo-redundant support for Frankfurt and connect with new data center clusters and high-availability zones.
The BER02 campus is characterized by:
- Scalable Capacity: up to 144 MW of IT power, across more than 46,800 m² of white space, ready for high-density racks, with air, liquid, or hybrid cooling.
- Energy Efficiency: integration of local renewable energies (wind and solar), with a designed PUE of 1.2 or lower.
- Sustainability: LEED-certified campus, zero process water consumption, extensive green areas, and architecture aimed at minimizing environmental impact.
- Technical Flexibility: adaptable racks for OCP, direct chip liquid cooling, n+1 or N+2C redundancies, multiple carrier entry points, and modularity for rapid scaling.
- Speed and Expertise: development led by local experts and accelerated delivery, thanks to know-how in complex projects and collaboration with leading suppliers.
A Strategic Move for the New European Digital Economy
The data center market in Germany — particularly in Frankfurt and Berlin — is experiencing unprecedented expansion, driven by the demand for artificial intelligence services, cloud computing, and advanced computing. The increased investment in these sectors and the rise of AI startups in London, Berlin, and other European capitals is driving the need for scalable, efficient, and sustainable infrastructure.
Founded in 2012, maincubes has established itself as a leading partner for large cloud and AI deployments, offering solutions that combine innovative design, proximity to major connectivity hubs, and a strong environmental commitment. With the launch of FRA03 and BER02, the company aims to lead the European digital transformation, aligning its strategy with policies on energy transition, efficiency, and resilience.
The Future of Data Centers: Sustainability and High Performance
The integration of technologies such as liquid cooling, waste heat recovery, and 100% renewable energy marks a turning point in the operation of data centers in Europe. The maincubes projects in Schwalbach and Berlin will pioneer the combination of high power densities, critical availability, and environmental respect, anticipating ESG regulations and the demands of large cloud and artificial intelligence clients.
As Thomas Wacker, Chief Development Officer of maincubes, states: “With BER02 and FRA03, we are creating future-ready infrastructures capable of adapting to the technological needs of the next decade, without compromising on the sustainability and efficiency demanded by the digital society.”
