Project Overview
This project supports a C&I customer in an Eastern European country, focusing on peak shaving and energy arbitrage to reduce electricity expenses and improve energy utilization.

Our Solution
Wenergy deployed a 5.16MWh BESS (20×258kWh) using the Stars Series 258kWh Outdoor All-in-one ESS Cabinet. The system features a compact, integrated design combining battery, PCS, cooling, and safety systems. With >89% system efficiency, intelligent liquid cooling, and multi-layer fire protection, it ensures stable and safe operation. A cloud-based EMS enables real-time monitoring and optimized charge-discharge strategies.

Key Highlights

• Total capacity: 5.16MWh
• Modular design for scalable deployment
• >89% efficiency for improved ROI
• Bidirectional PCS for on/off-grid flexibility
• Advanced safety and thermal management system

Conclusion
This project demonstrates how Wenergy’s integrated BESS solutions enhance energy efficiency, reduce operational costs, and support a more resilient and sustainable energy future for C&I users.
