Siemens and Rittal partner to design data center infrastructure of the future
- March 18, 2026
Siemens and Rittal have entered a strategic partnership to jointly develop future-proof, sustainable solutions for more efficient data center power distribution in the IEC market.
The standardized infrastructure is intended to accelerate the construction of high-performance data centers, minimize time-to-compute, and address the rapidly increasing power densities of AI applications.
Rising power densities
In AI data centers, power densities exceeding 100 kW per rack have become the norm. By 2030, the power density could increase to more than 1 MW. This requires innovative architecture for power distribution, cooling, and heat recovery. To address this, Siemens Smart Infrastructure, a leading international technology partner for efficient and safe power distribution, is partnering with Friedhelm Loh Group and its largest company Rittal, a global supplier of racks and standardized infrastructure, including power and cooling for leading hyperscalers.
“Sidecar” application
One of the first joint solutions will be a “sidecar” application that is housed directly in the white space of a data center, where the server cabinets and data storage are located. By bundling the power electronics in a dedicated power rack that supplies the server racks, this type of power supply represents a breakthrough for future AI applications. It provides computing units with a fast, simple, standardized, and scalable supply of power. OCP standards and the modular solution with tested technology from Rittal and Siemens ensure fast deployment, high availability, reliable operation, and maximized tokens-per-watt. These are the prerequisites for quickly bringing these relevant technologies to the digital economy.
Siemens-Rittal collaboration
Other Siemens and Rittal projects include the development of a standardized low-voltage distribution system for modular and containerized data centers as well as optimized solutions for operational and personal safety. The first customer projects are already underway.
These data center applications are made possible by the coordinated components from Siemens and the power distribution platforms RiLineX and Ri4Power from Rittal Energy & Power Solutions. The collaboration between Siemens and Rittal is set to extend to other industries and applications in the future.
