(IN BRIEF) Siemens and Rittal have formed a strategic partnership to develop advanced, standardized power distribution solutions tailored to the growing demands of AI-driven data centers. With power densities expected to exceed 1 megawatt per rack by 2030, the collaboration focuses on creating scalable and efficient infrastructure aligned with IEC standards. A key innovation is the introduction of a “sidecar” power rack installed directly within data center white space, enabling faster, more flexible, and reliable power delivery to server systems. In addition, the companies are developing standardized low-voltage distribution systems and enhanced safety solutions for modular data centers. Supported by integrated technologies such as RiLineX and Ri4Power, and already progressing through initial customer projects, the partnership aims to accelerate the deployment of high-performance data centers and expand into broader industrial applications.

(PRESS RELEASE) MUNICH, 17-Mar-2026 — /EuropaWire/ — Siemens and Rittal have expanded their collaboration through a strategic partnership focused on developing advanced, future-ready power distribution solutions for data centers. The initiative is designed to support the growing demands of AI-driven computing environments by delivering highly efficient, standardized infrastructure aligned with IEC standards, helping accelerate the deployment of high-performance data centers worldwide.

As artificial intelligence workloads continue to intensify, data centers are experiencing rapidly increasing power densities, already exceeding 100 kilowatts per rack and expected to rise to more than 1 megawatt per rack by 2030. This shift is driving the need for new approaches to power distribution, cooling, and energy management. Siemens Smart Infrastructure, in collaboration with the Friedhelm Loh Group and its flagship company Rittal, aims to address these challenges with scalable and efficient solutions tailored to next-generation data center requirements.

A central innovation emerging from the partnership is a next-generation “sidecar” power rack designed to operate directly within the white space of data centers, where servers and storage systems are located. This solution integrates power electronics into a dedicated unit that supplies energy directly to server racks, enabling a faster, more flexible, and standardized approach to power delivery. The system is designed to ensure rapid deployment, high availability, and reliable performance while supporting improved energy efficiency and optimized computing output.

Prof. Dr. Friedhelm Loh, owner and CEO of the Friedhelm Loh Group, highlighted the significance of strengthening the collaboration with Siemens, emphasizing the shared commitment to innovation and the responsibility to enhance customer competitiveness through advanced technologies.

Andreas Matthé, CEO of Electrical Products at Siemens Smart Infrastructure, underscored the urgency of delivering scalable and dependable power solutions to support the rapid expansion of AI infrastructure, noting that the partnership with Rittal enables faster deployment and greater standardization across data center environments.

Beyond the sidecar power rack, the companies are also working on standardized low-voltage power distribution systems for modular and containerized data centers, as well as enhanced solutions for operational safety and personnel protection. These developments are already being implemented in initial customer projects.

The solutions are supported by coordinated technologies from Siemens alongside Rittal’s power distribution platforms, including RiLineX and Ri4Power, which together enable efficient and scalable energy management. Looking ahead, Siemens and Rittal plan to extend their collaboration beyond data centers into additional industries and applications, leveraging their combined expertise to drive innovation across sectors.
