On November 2, 2026, Envision Technology Group announced that its integrated 800V high-voltage direct current power supply system has been put into commercial operation at the Ulanqab Galaxy Base. Sina Tech reported that the system consists of the Tianshu controller, solid-state transformers, DC energy storage, and DC/DC, and is the world's first system of its kind to operate commercially in a large AI data center; the Galaxy Base was put into production in August this year, has a planned capacity of 3GW, and will have a direct green power connection ratio exceeding 80%. On the same day, Unite.AI reported that Envision said the system has been carrying actual computing loads at the Galaxy AI data center in Ulanqab, covering end-to-end power supply from medium-voltage AC input to server racks, with the Dubhe controller working in conjunction with the Dubhe energy foundation model to adjust transformers and batteries in real time to follow GPU load fluctuations; the park is designed to support up to 1 million AI accelerators running in parallel at full load.

Envision deploys 800V DC power supply system at Ulanqab AI data center
Envision announced that its Galaxy AI data center in Ulanqab, Inner Mongolia, is now carrying actual computing loads with an 800V DC power supply system, which the company says is the first commercial application of this system in a large-scale AI data center. The system covers end-to-end power supply from medium-voltage AC input to server racks, integrating solid-state transformers, battery energy storage and DC voltage regulation equipment, with the Dubhe controller working alongside the Dubhe energy foundation model to adjust transformers and batteries in real time to follow GPU load fluctuations. Envision says the architecture can improve power conversion efficiency, reduce equipment footprint and cut cable and copper usage; the Galaxy campus is planned for 3GW capacity, with a full-load design supporting up to 1 million AI accelerators running in parallel.
