Battery Energy Storage System

Kawan Green Energy delivers Battery Energy Storage System (BESS) solutions that help commercial, industrial and utility customers optimise energy consumption, reduce electricity costs, improve power reliability and support renewable energy integration. Our systems are engineered for peak shaving, load shifting, backup power, microgrids and hybrid energy applications.

Kawan Green Energy offers advanced Battery Energy Storage System (BESS) solutions in Malaysia that store electricity in high-performance rechargeable batteries for use whenever it is needed most. By capturing energy from the grid or renewable sources such as solar and wind, BESS ensures that valuable energy is not wasted. Its core components—including battery cells, the Power Conversion System (PCS), Energy Management System (EMS), Battery Management System (BMS), transformers, HVAC, and fire suppression systems—work seamlessly together to optimise energy flow, maximise efficiency, and ensure safe, reliable operation.

BESS provides instant backup power, enhances grid stability, and maximises the value of renewable energy by storing excess electricity during off-peak periods and discharging it when demand is high. It also helps businesses reduce peak demand charges, improve power quality, and optimise electricity consumption through peak shaving, load shifting, demand response, and energy arbitrage strategies.

Today, Battery Energy Storage Systems are widely deployed in commercial buildings, manufacturing facilities, hospitals, data centres, utilities, and renewable energy projects to improve energy resilience and operational efficiency. By integrating BESS, organisations can lower operating costs, reduce carbon emissions, increase renewable energy utilisation, and build a more reliable and sustainable energy future.

Benefits of BESS

  • Energy Reliability: Provide backup power during outages, ensuring a continuous power supply

  • Grid Stabilization: Help balance supply and demand, reducing the risk of blackout and improving grid stability

  • Renewable Integration: Store excess energy from renewable sources like solar and wind. This stored energy can be released when demand exceeds production. This technology plays a crucial role in integrating and increasing the penetration of renewable energy into our electricity grids by helping to address the inherent supply-demand imbalance of intermittent renewable sources

  • Enhanced Energy Autonomy: Empower homes and businesses equipped with solar energy systems to capture and store surplus energy. This capability reduces dependence on external power grids, enhancing local energy self-sufficiency

  • Cost Savings: By storing energy during off-peak times and using it during peak demand, BESS can reduce energy costs

  • Environmental Impact: Support the transition to cleaner energy sources, reducing reliance on fossil fuels and lowering greenhouse gas emissions

Battery Energy Storage Applications

Peak Shaving
Reduces the peak electricity demand by using stored energy to meet part of the demand. This helps in lowering electricity costs and reducing the need for new power plants or upgrades to the existing grid.

Load Shifting
Uses BESS to optimize energy consumption and reduce costs by redistributing electricity usage drawn from grid during peak demand periods to off-peak times.

Microgrid Support
Vital for the functionality of microgrids, BESS provides the necessary energy storage capacity to maintain operations independently from the main grid.

Renewable Energy Intergration
BESS enhances the reliability and stability of green energy initiatives by storing excess energy when renewable sources like solar and wind are abundant and releasing it when production reduces.

What is a Battery Energy Storage System (BESS)?

Peak shaving is one of the most effective applications of a Battery Energy Storage System (BESS). During periods of high electricity demand, the BESS automatically discharges stored energy to reduce the facility’s peak power consumption from the grid. By lowering the maximum demand (MD), businesses can significantly reduce electricity charges while maintaining uninterrupted operations.

Typical Applications

Peak shaving is widely adopted across industries with high and fluctuating power demand, including:

  • Manufacturing Facilities – Reduce maximum demand charges and improve production energy efficiency.
  • Data Centres – Support critical IT loads while minimising peak electricity costs.
  • Commercial Buildings – Office towers, shopping malls and mixed developments with variable daily energy demand.
  • Hospitals – Maintain reliable power for essential medical equipment while optimising energy expenditure.
  • Hotels & Resorts – Manage peak air-conditioning loads and reduce utility costs during high occupancy periods.
  • Industrial Plants – Optimise electrical load profiles and improve overall energy management.

A Battery Energy Storage System (BESS) is an advanced energy solution that stores electricity for use when it is needed most. It enables businesses to reduce peak demand charges, improve power reliability, integrate renewable energy sources, and optimise overall energy consumption. BESS is widely used in commercial buildings, industrial facilities, data centres, and utility-scale applications to support a more efficient and sustainable energy infrastructure.

  • Key Components of a BESS:

  • Battery Cells: The core energy storage component that stores and releases electrical energy. Lithium-ion battery cells are commonly used due to their high energy density, long cycle life, and reliable performance.

  • Power Conversion System (PCS): Converts electricity between AC and DC, enabling seamless charging and discharging of the battery while maintaining stable power quality.

  • Energy Management System (EMS): An intelligent control platform that monitors energy usage, optimises battery operation, and maximises energy savings through functions such as peak shaving, load shifting, and renewable energy integration.

  • Battery Management System (BMS): Continuously monitors battery voltage, temperature, and state of charge to ensure safe operation, maximise battery lifespan, and protect against abnormal conditions.

  • HVAC System: Maintains the optimum operating temperature and humidity inside the battery enclosure, ensuring reliable performance and extending battery life.

  • Fire Suppression System: Provides early detection and automatic fire suppression to enhance operational safety and protect the battery system in the event of a thermal incident.

  • Transformer: Adjusts the system voltage for safe and efficient connection between the BESS and the electrical grid or facility power distribution system.
