World's Largest 12.8 GWh Battery Storage Cluster Activated in China

Envision Group has completed the integration of artificial intelligence management systems into a 12.8-gigawatt-hour battery storage network in northern China that came online last February. The technology developer announced that its 4-gigawatt-hour flagship facility, known as the Envision Jingyi Chagan Hada Energy Storage Power Station, represents what the company characterizes as potentially the world’s largest single-site electrochemical energy storage installation.

The integrated AI system applies machine learning algorithms to battery management operations, enabling real-time automated decision-making capabilities. The software interfaces with local electricity spot markets to analyze price trends and demand forecasts, optimizing when to charge and discharge batteries based on grid conditions. According to company sources, these predictive algorithms are projected to increase lifetime revenue by approximately 20 percent compared to conventional fixed-schedule storage facilities.

The flagship plant achieved full commercial operation following comprehensive grid verification testing, completing multiple charge and discharge cycles at rated capacity and successfully passing a 72-hour operational trial conducted in winter conditions on the Inner Mongolian steppe. The facility functions as the central hub for a broader network of storage installations distributed across several regional energy centers, collectively bringing Envision’s total operational storage capacity in Inner Mongolia to more than 14 gigawatt-hours.

Inner Mongolia serves as a major clean energy production region in China, generating substantial wind and solar capacity that frequently exceeds local grid demand. Large-scale battery storage systems address the challenge of renewable energy curtailment by absorbing excess daytime generation and releasing stored power during peak consumption periods, while also supporting long-distance transmission corridors to major eastern Chinese metropolitan areas.

Envision has also commissioned the Galaxy Campus, a 2-gigawatt green energy computing facility in Ulanqab designed to support high-density artificial intelligence infrastructure. The data center draws power directly from regional wind farms and relies on the battery storage cluster to provide continuous zero-carbon electricity to computing operations.
