Envision says 800V DC power system running at Inner Mongolia AI site

Envision says it has begun commercial operation of a power system that feeds AI equipment directly with 800 volts of direct current at its Galaxy AI campus in Ulanqab, Inner Mongolia, according to TechRadar. The Chinese company calls the setup the first commercial use of this configuration. Trials of its Dubhe controller and the related energy model started at the site in August 2026.

Envision has not released independent performance figures, so the claimed gains remain unverified by outside parties. Typical data centres pass incoming electricity through multiple conversion stages before it is fit for servers and accelerators, which requires extra equipment and can waste energy along the way.

By cutting those stages, the company says its design raises electrical efficiency and shrinks the floor space taken up by power hardware. Distributing electricity at a higher voltage can also trim the volume of copper needed for cabling, which may matter as computing sites grow quickly and demand more material.

The architecture pairs the power distribution with battery storage. Envision says the batteries respond within seconds when processor demand shifts and provide temporary backup power during unexpected outages, with backup lasting several minutes. A controller synchronises the transformer and the batteries in milliseconds, a task aimed at absorbing the sharp swings in consumption that GPUs produce.

Those swings put strain on the electrical infrastructure behind densely packed AI hardware. Envision also says the design supports racks with higher power density, letting operators fit more computing capacity into the same footprint.

The Galaxy site is expected to reach 3 gigawatts. Envision says the completed facility would have enough capacity to run a million AI accelerators. The company also plans to spread the technology through Mission Gobi, a programme targeting 5 gigawatts of renewable-powered computing by the end of the decade.

That effort centres on desert regions, where Envision expects renewable generation and storage to back large computing builds. The system is designed to run alongside renewable sources, with batteries balancing supply against changing compute needs.

Envision has not published independently verified measurements of efficiency gains, installation costs or savings relative to conventional power systems. The announcement also leaves open how the architecture holds up under sustained full load, or across sites using very different hardware. The deployment is a commercial milestone for the company, while the size of its claimed advantages still awaits detailed outside evidence.
