Envision said on Nov. 2, 2026 that it has put an integrated 800-volt direct current (800V DC) power system into commercial operation at its Galaxy AI data center campus in Ulanqab, China. The company describes it as the world's first such deployment in a large-scale AI data center. The system is powering live computing workloads and delivers power from grid input to the computing loads.
What the system includes
The setup combines solid-state transformers (SST), battery energy storage (BESS) and equipment that adjusts direct-current voltage for computing hardware. Envision lists three capabilities: stable SST conversion straight from 10 kV medium voltage to an 800V DC bus, battery storage that gives both second-scale power support and minute-scale backup, and millisecond-level coordination between the SST and storage to absorb GPU load swings locally.
Envision's Dubhe Controller, supported by its Dubhe Energy Foundation Model, coordinates the transformers and batteries in real time to match supply with computing demand and handle sudden load swings.
Envision says the 800V DC design simplifies the power chain, raises conversion efficiency, shrinks the equipment footprint and cuts cabling and copper needs. It adds that these gains can lower infrastructure costs and allow higher computing density in the same space.
The campus
The Galaxy campus began operations in August 2026. Its planned capacity is 3GW, enough to support up to one million AI accelerators running in parallel at full build-out. More than 80% of its power is planned to come from direct renewable electricity connections.
Envision aims to scale the approach through its Mission Gobi initiative, which targets 5GW of green AI data center capacity in desert regions worldwide by 2030.
Kevin Huang, Senior Vice President of Envision Energy and President of Energy Storage and AIDC Power Systems, said the system turns power-compute coordination "from a strategic vision into an operational reality."
