Hitachi Energy is developing a power system simulation using NVIDIA Omniverse libraries to help accelerate AI factory deployment.
BERLIN, Germany, Oct 23, 2026 (JCN Newswire) - Hitachi Energy today announced a new simulation capability with integrated NVIDIA Omniverse libraries that enables data center teams to evaluate how future AI factory power systems may perform before they are built. The capability adds to the wider NVIDIA DSX Sim partner ecosystem. By bringing together AI load scenarios and power system models in a shared digital environment, it helps teams compare alternative designs, assess resilience, and make more informed decisions earlier in the planning process.
Power infrastructure is a critical factor in the speed and scale of AI factory deployment. Electricity demand from data centers increased by 17 percent in 2025, while consumption from AI-focused facilities grew even faster, significantly outpacing overall global electricity demand growth. As operators work to accelerate AI infrastructure deployment, they must make critical design decisions that affect their ability to deliver with speed, reliability, scalability, and long-term resilience.
Hitachi Energy's new simulation capability initially focuses on 800-volt direct current (VDC) architectures, which are being developed to support the growing power density and efficiency requirements of next-generation AI factories. As the industry explores 800 VDC as a new approach to power distribution, grid-to-rack simulation can help provide insights into system behavior and performance before deployment at scale.
Building on its close collaboration with NVIDIA for 800 VDC AI factories, the simulation enables teams to examine how different operating conditions, load profiles, and resilience scenarios may affect grid-to-rack system performance before physical assets are adopted. Using Open USD-based workflows powered by NVIDIA Omniverse libraries, the shared environment allows engineering data and Hitachi Energy power system models to be evaluated together. The goal is to support comparison of design alternatives, validation of assumptions, and more informed infrastructure decisions earlier in the planning process.
"AI is rapidly becoming an infrastructure challenge as much as a computing challenge," said Marco Berardi, Head of Grid & Power Quality Solutions and Service at Hitachi Energy. "As AI factories scale, access to electricity, power system design, and the ability to deploy infrastructure at speed are becoming increasingly important. By combining Hitachi Energy's electrification expertise with NVIDIA Omniverse libraries, we enable customers to explore and optimize power architectures across the AI factory power chain before deployment, helping accelerate time to power."
The development is part of a broader collaboration between Hitachi and NVIDIA to accelerate digital transformation with generative AI and follows the recent qualification of Hitachi Energy's battery energy storage system as NVIDIA DSX Ready BESS. That qualification helps customers identify infrastructure building blocks that meet applicable NVIDIA DSX reference design requirements for resilient, reliable, and scalable AI factory power systems.
