The world’s largest single-site electrochemical energy storage power station—the Envision Jingyi Chagan Hada Energy Storage Power Station—was successfully connected to the grid, completing a 12.8 GWh AI-powered energy storage cluster in Inner Mongolia. The project sets new global benchmarks for scale, grid-connection speed, and system reliability, while demonstrating advanced grid-forming capabilities that enable rapid commissioning, deep grid interaction, and large-scale renewable integration.
