World's First Commercial Deployment of Integrated 800V DC Power System

Introduction

Envision, a frontrunner in green technology, has unveiled a significant advancement in the energy sector: the world's first commercial deployment of an integrated 800-volt direct current (800V DC) power system at its AI data center campus in Ulanqab, China. This innovative system combines solid-state transformers (SST), battery storage, and AI-driven controls to effectively optimize the power supply from the grid to the computing equipment.

The Significance of the 800V DC Power System

This state-of-the-art 800V DC architecture marks a pivotal shift in the way power is supplied to large-scale AI data centers. By simplifying the power system requirements, it not only enhances power conversion efficiency but also maximizes watt-to-bit performance, reduces the overall equipment footprint, and lowers the demand for extensive cabling and copper materials. These efficiencies translate into reduced infrastructure costs and allow for higher computational density within a fixed area, which is critical as AI applications evolve.

Kevin Huang, Senior Vice President of Envision Energy and head of Energy Storage and AIDC Power Systems, emphasized the need for AI data centers to align their power systems with renewable energy sources to meet fluctuating computing demands effectively. He stated, “Our integrated 800V DC system is now powering live computing workloads, demonstrating an end-to-end architecture that connects renewable energy supply with computing demand.”

How the System Works

This breakthrough power system integrates several critical components:
1. Solid-state transformers (SST) that provide stable voltage conversion from medium-voltage AC inputs to 800V DC.
2. Battery energy storage systems (BESS) for immediate power support and backup.
3. Advanced coordination capabilities that enable rapid adjustments to the power supply in response to sudden shifts in computing loads.

Using Envision's proprietary Dubhe Controller, which is supported by the Dubhe Energy Foundation Model, the system can dynamically manage the transformers and batteries, aligning power supply with real-time computing needs.

Current and Future Applications

Launched in August 2026, the Galaxy campus is designed with a capacity of 3GW, aiming to support up to one million AI accelerators operating simultaneously. Notably, it plans to source more than 80% of its power from direct renewable energy connections, underscoring Envision’s commitment to sustainability.

As demand for AI computing grows exponentially, this innovation sets a precedent for the industry, validating the viability of transitioning to 800V DC infrastructure for future AI data centers. Envision’s efforts align with its Mission Gobi initiative, which aims to establish 5GW of green AI data center capacity in desert regions by 2030.

Conclusion

With the successful deployment of the 800V DC power system, Envision not only contributes to the ongoing energy transition but also takes a significant step toward sustainable AI computing. The integration of reliable power systems is crucial as industries strive for efficiency and sustainability. Envision’s pioneering work promises a more connected and eco-friendly future for AI data centers worldwide.
