Envision says an 800 V DC power system with solid-state transformers is now running live AI workloads at its Ulanqab campus
What changed
Envision says an integrated 800 V DC system now carries power end to end, from 10 kV medium-voltage AC input to the server racks, at its Galaxy AI data centre campus in Ulanqab, Inner Mongolia, and calls it the first commercial deployment of its kind in a large AI data centre (company claim). The system combines solid-state transformers, DC battery storage and DC/DC converters, coordinated by Envision's Dubhe controller to absorb GPU load swings within milliseconds. The campus began operating in August 2026 and is planned for 3 GW, with more than 80% of its power planned from direct renewable connections (company plans).
