World’s largest AI-powered battery storage cluster comes online in China

China has commissioned the world's largest Al-powered battery storage cluster, a significant step forward in grid-scale energy storage and intelligent power system management. The cluster contains a record-breaking 4 GWh single-site energy storage power station, the Envision Jingyi Chagan Hada Energy Storage Power Station, as part of a larger 12.8 GWh energy storage network spanning Inner Mongolia.

The flagship plant, which was successfully connected to the grid in late December 2025, combines high-capacity batteries with powerful artificial intelligence algorithms to optimize charging, discharging, and grid interactions in real time. This project is a key component in China's rapid deployment of energy storage assets intended to promote renewable generation, improve grid flexibility, and enable a smarter, more robust power infrastructure.

The Jingyi Chagan Hada facility, which can balance substantial amounts of intermittent solar and wind power, is the largest electrochemical energy storage project at a single location in the world at 4 GWh. It proved to be incredibly reliable after passing stringent "three charge and three discharge" performance testing and operating continuously for 72 hours on its first attempt.

Envision Energy, the deployment's principal business, has increased its cumulative energy storage footprint in Inner Mongolia over 14 GWh by merging various distributed facilities spanning Bayannur, Ordos, Hohhot, Ulanqab, Xilingol League, and Alxa League.

Liu Wei, Chief Technology Officer at Envision Energy, stated, "Our goal was to redefine what large-scale energy storage can achieve." We've produced the biggest and smartest storage asset of its type by fusing cutting-edge Al with reliable electrochemical technology. Liu stated that years of research, iterative testing, and cooperation with local grid operators were essential to completing the project on time and achieving performance goals. The system learns and adapts to grid demands, forecasted solar outputs, and price signals, ensuring maximum value for stakeholders.

The Al-powered cluster goes live at a time when energy storage is becoming increasingly important for grid dependability in markets with growing wind and solar power shares. The system's size and intelligence help to reduce intermittency, provide auxiliary services such as frequency regulation, and reduce reliance on fossil-fuel-based peaking facilities.

As China accelerates its transition to a low-carbon energy future, projects like the Envision Jingyi Chagan Hada cluster, which combines vast capacity with artificial intelligence, are expected to play a critical role in balancing variable renewable inputs and maintaining cost-effective grid operations.
