Hitachi has introduced its advanced 800-volt direct current (800 VDC) power and control architecture, fully integrated into the Vera Rubin DSX reference design and compatible with the NVIDIA Omniverse DSX Blueprint. The innovation is aimed at enabling efficient and scalable power delivery for future gigawatt-scale AI factories.
At the core of this announcement is a three-dimensional (3D) simulation model, built using OpenUSD, which replicates power behavior across the entire electrical chain-from utility grids to data center racks. This capability allows developers and utility providers to design, test and deploy AI infrastructure with greater precision and speed. Attendees at NVIDIA GTC 2026 can explore a live demonstration of the architecture at Hitachi’s booth.
Bridging Digital Simulation with Real-World Infrastructure
The simulation model that has been newly developed combines the capabilities of industrial software with those of the Omniverse library, facilitating a smooth connection between physical infrastructure and virtual environments. This opens avenues for stakeholders to assess system reliability prior to execution.

Some of the key features of the solution are as follows:
SimReady Asset Integration: The solution is developed as SimReady assets, which are compatible with the NVIDIA Omniverse DSX Blueprint, thereby facilitating the transition from the design environment to the real world.
Grid Stability Optimization: The solution is capable of providing a stable and consistent delivery of 800 VDC rack power, even with fluctuating AI workload requirements. The solution minimizes the effect of power disturbance by utilizing the energy storage of the batteries.
Predictive Management Capabilities: The solution is integrated with various types of thermal, condition, and asset health models, which facilitate predictive as well as prescriptive maintenance, ranging from the data center environment to the substations and the grid itself.
Powering the Future of AI Infrastructure
This comes as a result of the continued partnership between Hitachi and NVIDIA with regards to providing an efficient DC power solution for the future of computing. This comes at a time when AI applications are expected to increase global electricity demand by as much as 125 gigawatts by the year 2030. The modern power architectures are thus becoming essential to supporting such increases.
The role of the 800 VDC architecture in modern computing cannot be overstated, as it provides the ability to handle as much as 15 times more power with a smaller footprint.
“No one has yet experienced the AI workloads and power demands of tomorrow’s gigawatt-scale AI factories. The aim is to scale fast without compromising quality and to safeguard the grid, chips, and entire electrical chain,” said Anthony Allard, Executive Vice President and Chief Marketing and Sales Officer, Hitachi Energy. “We’ve created a seamless convergence of the physical and digital worlds—simulating thousands of end-to-end scenarios to design for what’s next. Our work with NVIDIA proves what our collaboration can achieve.”
“As energy becomes the primary bottleneck for AI infrastructure, the industry requires sophisticated simulation tools to manage the unprecedented power densities and interconnection backlogs of gigawatt-scale AI factories.” said Vladimir Troy, Vice President of AI Infrastructure at NVIDIA. “The integration of Hitachi’s power solution simulations with the NVIDIA Omniverse DSX blueprint enables developers to model the full electrical chain—from the utility grid to the data center rack—to accelerate the deployment of energy-efficient AI infrastructure.”
