Siemens has published a reference electrical and power architecture for data centers running Nvidia’s Vera Rubin NVL72 platform, developed alongside Nvidia, battery storage vendor Fluence, and thermal management company nVent.

The design targets a 136MW facility with 100MW of IT load, covering the full electrical path from a 34.5kV utility connection through medium-voltage distribution to the rack. It is built to Tier III concurrent maintainability standards, meaning any single component can be taken offline without disrupting IT operations.

The architecture will be modular, with Siemens claiming that deployments can start at tens of megawatts and scale to hundreds without requiring a fundamental redesign. Pre-fabricated medium- and low-voltage skids are intended to reduce on-site construction work and shorten commissioning times.

“Siemens’ deep expertise in power systems and controls engineering, modular infrastructure, protection, and industrialized delivery is really evident in this latest joint reference architecture design,” said Ruth Gratzke, president of Siemens Smart Infrastructure USA. “Our pre-engineered, prefabricated, and factory-tested medium- and low-voltage skids help minimize on-site construction complexity, shorten commissioning cycles, and improve quality, safety, and repeatability across deployments. Further, our automation and digital twin strategies deployed in this reference help ensure that facilities are brought online faster and with greater potential to produce tokens at scale.”

Fluence will integrate its Smartstack battery storage system into the design to handle grid instability events, such as voltage and frequency fluctuations, black start capability, and load smoothing for AI workloads, which can draw power unevenly.

As part of the partnership, nVent will provide thermal management services.

“nVent has deployed more than two gigawatts of liquid cooling capacity globally,” said Sara Zawoyski, president, nVent Systems Protection. “That operational experience is what allows us to help partners like Siemens translate reference architectures into deployable thermal solutions that perform reliably from day one at this scale. Platforms like Nvidia Vera Rubin NVL72 are pushing rack densities well beyond what traditional air-cooled infrastructure can support.”

The design also incorporates a centralized management platform, giving operators a unified view across power, cooling, and compute. Siemens has stated that a thermal management supplement to the reference design is planned.
