The project centers on a new building covering an area of over 40,000 m². Where a small switchgear facility once stood, a building unlike any other is now being constructed. It must meet the highest standards, demonstrate maximum stability, withstand high floor loads and at the same time be scalable and flexible. Every square meter counts and every kilogram is crucial to ensure that the overall project can realize its full potential.
The Technology Center Laufenburg presents itself as a precisely composed structure that harmonizes technological requirements and architectural expression. The structure of the building is based on a modular system that allows for maximum flexibility in use and expansion.
The building blends in with its surroundings while also setting an example for innovation. The blue solar facade, covering an area of around 13,000 m², emphasizes an architectural design that responds flexibly to future technological developments.
The structure is clearly organized and follows a strict design logic. The supporting structure, access routes and technical areas are precisely coordinated, resulting in a building that is both functional and aesthetically pleasing.
The technology center is a pioneering project. There is no other building of this size that houses a data center and battery storage facility. The planning is correspondingly complex.
With the completion scheduled for 2028, the construction project is bound to a tight schedule. Planning, coordination and precision are the basis for the project's success. With rolling planning, every minute is optimized.
The Technology Center Laufenburg will be completely covered with a solar shell. State-of-the-art photovoltaic technology ensures that the building blends perfectly into the landscape while still reflecting innovation and sustainable construction.
The strategic location at the Star of Laufenburg enables a direct connection to the highest possible grid capacity. This unique selling point makes the location and the project a perfect match, because there is no second chance for an opportunity like this today.
The Technology Center Laufenburg (TCL) is divided into several areas: server infrastructure, power electronics, battery storage tanks, logistics and installation areas. The entrance area houses hundreds of square meters of office and assembly space, providing direct access to the storage facility and data center.
Info: The visualization corresponds to the planned status as of December 2025. Deviations in layout and subdivision are possible.

“The Technology Center Laufenburg is a building that transcends its architectural appearance. It is a place where energy, digitalization and architecture come together in a new way. The building’s structure responds to the high functional demands of a battery storage facility and an AI data center just as naturally as it fulfills the need for a clear, timeless architectural language.”
A pioneering redox flow battery storage facility is being built at the Technology Center Laufenburg, offering impressive sustainable, safe and fully recyclable technology. It supports the integration of renewable energies by storing surplus electricity and releasing it again when needed. This stabilizes the grid, reduces the risk of outages and strengthens the security of supply in Switzerland and Europe.
The AI data center combines cutting-edge technology with the highest security standards and guarantees a future-proof, scalable solution for hyperscalers. The FlexBase “Sovereign AI Factory” sets new standards in terms of performance, security, sustainability and future-proofing.
The construction of the new technology center will create a modern campus for energy and innovation in Laufenburg. Covering an area of 40,000 m², the campus will combine battery storage, an AI data center, office space and laboratories. Sustainable construction, the highest safety standards and energy-efficient infrastructure make the site a showcase project for European technology development.
The waste heat from our AI data center at the Technology Center Laufenburg (TCL) can power not only Laufenburg but an entire regional ecosystem. Our heat extends for several kilometers and can transform fossil-fuel-fired power plants into backup systems. For us, sustainability isn’t just a concept — it’s actively planned and implemented.
To supply power to the Technology Center Laufenburg, FlexBase is building an industrial grid with a connection to Switzerland's highest grid level, comparable to the electricity highway. The grid is used for the fine distribution and conversion of electrical energy to lower voltages, to which the individual battery storage units and data center consumers are connected.
In a world that is increasingly relying on renewable energies, efficient and sustainable battery storage solutions play a key role. Our research and development department is working on innovative technologies that are driving the energy transition forward.
