Commercial and Industrial Battery Energy Storage Systems (C&I BESS) are designed to help businesses manage energy more efficiently and maintain stable power supply. These systems store electricity and discharge it during peak demand or grid instability, providing fast, clean, and reliable energy support for daily operations.
Battery energy storage enables peak shaving and load shifting, helping businesses reduce electricity costs and demand charges. It also delivers reliable backup power during outages, protecting critical equipment and minimizing downtime. When integrated with solar or other renewable sources, C&I BESS improves energy utilization and reduces dependence on diesel generators.
Due to higher power demand and system requirements, commercial and industrial energy storage is typically deployed in factories, logistics centers, EV charging hubs, commercial buildings, data centers, and solar-plus-storage projects where stable, scalable, and high-availability power is essential.
AnengJi provides scalable commercial and industrial battery energy storage solutions with flexible capacity configurations and seamless integration into existing energy systems. Designed for long-term reliability and easy deployment, our C&I BESS helps businesses lower operating costs, enhance energy resilience, and support sustainable growth.
