Smart Energy for Smarter Industries

Reduce Maximum Demand Charges with BESS + EMS

High electricity bills due to Maximum Demand (MD) charges can significantly impact your factory’s operating costs, especially for Medium and High Voltage (MV/HV) users.

With Canadian Solar’s Battery Energy Storage System (BESS) combined with an Energy Management System (EMS), your business can take control of energy usage, lower peak demand, and achieve smarter energy savings.
 

1. System Overview

The Canadian Solar KuBank is a modular, high-performance Battery Energy Storage System (BESS) designed to optimize energy use for commercial and industrial facilities. Integrated with a smart Energy Management System (EMS), the KuBank allows users to strategically manage load profiles, reduce maximum demand charges, and improve overall energy efficiency.
 

2. Core Technical Features

Long Service Life

• Uses LFP 280Ah lithium-iron-phosphate cells with over 20 years of lifespan (one cycle per day).

• Ensures stable, long-term energy storage performance for daily charge/discharge cycles typical in peak shaving operations.

Plug-and-Play Flexibility

• Modular architecture simplifies installation, commissioning, and scalability.

• Ideal for industrial facilities looking to add or expand BESS capacity to align with evolving load demands.

ùà Efficient and Intelligent BMS

• Advanced Battery Management System with 2A active balancing maximizes energy utilization and extends cell lifespan.

• Enables real-time state-of-charge (SOC) monitoring, essential for precise EMS control during peak demand periods.

Intelligent Liquid Cooling

• Maintains temperature deviation within ±3°C, ensuring consistent performance even under heavy cycling during peak hours.

• Enhances safety and battery longevity under Malaysia’s hot and humid climate.

þ High-Level IP Protection & Safety System

• Battery pack rated IP67, enclosure rated IP54, offering superior protection against dust and moisture.

• Multi-layer fire detection, thermal runaway prevention, and zone isolation ensure high operational safety for industrial environments.

þ High-Performance PCS

• Up to 98% efficiency Power Conversion System (PCS) enables rapid charge/discharge response.

• Supports multi-electrical level topology, allowing fast transition between grid and battery operation during peak shaving.

Intelligent Operation & Maintenance

• Equipped with 5G and LAN connectivity for real-time cloud integration.

• EMS platform allows remote monitoring, scheduling, and predictive analytics, minimizing human intervention and downtime.
  
  
  
  
   

3. Peak Shaving and Demand Charge Reduction

þ How It Works:

1. During Peak Hours:

   • The EMS detects grid demand spikes and automatically discharges the BESS to supply partial load power.

   • This reduces Maximum Demand (MD) recorded by TNB, directly lowering monthly demand charges.

2. During Off-Peak Hours:

   • The BESS recharges using cheaper off-peak electricity or excess solar PV energy.

   • Optimizes total energy cost and improves the return on investment.

3. Integrated Solar + BESS Operation:

   • When paired with a solar PV system, KuBank stores surplus daytime generation and releases it during evening peaks, further minimizing grid reliance.
