Envision Commissions China's First Commercial 800V DC Data Center

Envision says it has put an integrated 800V DC power architecture into commercial operation at its Galaxy AI campus in Ulanqab, Inner Mongolia. The system uses a solid-state transformer to convert 10kV AC grid power directly to 800V DC, paired with battery storage and its Dubhe controller. No independent efficiency or cost figures have been disclosed.

A commercial 800V DC architecture that removes intermediate conversion stages targets one of the main constraints on AI data center build-outs: power delivery and density. It aligns with the high-voltage DC direction Nvidia is pushing for next-generation racks, and may favor solid-state transformer and power-electronics suppliers over conventional AC UPS and switchgear vendors. Integrated battery buffering for GPU load swings also adds to the demand case for storage. Claims are unverified, with no disclosed efficiency, cost or full-load data, so the near-term market impact is limited. The planned 3 GW Galaxy campus and the 5 GW Mission Gobi program give the architecture a potential path to scale in China's desert renewable-powered compute.
