Envision Group has completed the integration of an artificial intelligence management system into a large battery storage network in Inner Mongolia, according to announcements released this week. The network, which became operational last February, encompasses a 4-gigawatt-hour flagship facility at Chagan Hada that company sources describe as potentially the world’s largest single-site electrochemical energy storage installation.
The AI system automates real-time operational decisions by monitoring battery cell thermal behavior and coordinating charging and discharge cycles based on grid conditions. The technology also interfaces with local electricity spot markets, analyzing price trends and demand forecasts to optimize when power is stored and released. Engineers estimate the predictive software will increase lifetime revenue by approximately 20 percent compared to conventional fixed-schedule storage facilities.
The Chagan Hada plant reached full commercial operation following grid verification testing that included three complete charge-discharge cycles at rated capacity and a 72-hour trial run conducted during winter conditions on the Inner Mongolian steppe. The facility serves as the central hub for a broader network of energy storage installations distributed across multiple regional centers including Bayannur, Ordos, Hohhot, and other locations. Together, these installations bring Envision’s total operational storage capacity across Inner Mongolia to more than 14 gigawatt-hours.
Inner Mongolia is a major clean energy production region in China, generating substantial wind and solar capacity that frequently exceeds local grid capacity. Large-scale battery storage systems absorb surplus daytime generation and release electricity during peak demand periods, reducing renewable energy curtailment and stabilizing long-distance transmission corridors serving eastern China’s major cities. The storage cluster now directly powers industrial and computing infrastructure, including Envision’s Galaxy Campus data center facility in Ulanqab designed to support up to one million accelerators.
