China’s Envision has put an integrated 800-volt direct-current power system into commercial operation at its Galaxy AI data center campus in Ulanqab, Inner Mongolia, as operators across Asia build infrastructure for denser artificial intelligence workloads.
The company said in a November 2 announcement that the system is powering live computing workloads from the grid connection through to computing loads. Envision described the project as the world’s first commercial deployment of an integrated 800V DC architecture at a large-scale AI data center.
Power conversion and storage work as one system
The deployment combines solid-state transformers, battery energy storage and equipment that adjusts direct-current voltage for computing hardware. Envision said its Dubhe Controller, supported by the company’s Dubhe energy foundation model, coordinates the transformers and batteries in real time to match supply with computing demand and manage sudden changes in accelerator loads.
The company said the system converts 10-kilovolt medium-voltage alternating current directly to an 800V DC bus. Battery storage provides second-scale power support and minute-scale backup, while millisecond-level coordination between the transformer and storage components is intended to absorb load fluctuations locally.
Higher-voltage direct-current architectures are being developed for AI facilities because they can reduce conversion stages, cabling and equipment space as the power density of server racks rises. Envision said its configuration is designed to improve power-conversion efficiency and allow more computing capacity in the same physical footprint. It did not disclose project cost, measured efficiency data or the installed capacity of the operating system in the announcement.
Galaxy campus targets gigawatt-scale expansion
The Galaxy campus began operations in August 2026. Envision now says the site is planned to reach 3 gigawatts and support as many as one million AI accelerators at full build-out, with more than 80 percent of its electricity planned to come from direct renewable-power connections. Those are forward-looking company targets rather than current operating figures.
The latest power-system deployment builds on the campus commissioning, when Envision presented the Ulanqab project as a model combining renewable generation, transmission, storage and high-density computing. Ulanqab’s wind and solar resources and its role as a data infrastructure hub have made the northern Chinese city a location for large computing projects.
Envision said it intends to use the Ulanqab system as a reference for its Mission Gobi initiative, which targets 5 gigawatts of green AI data center capacity in desert regions worldwide by 2030. The company has not provided a schedule for additional commercial deployments.
