What is Bess
What is a Battery Energy Storage System in Malaysia?
A Battery Energy Storage System (BESS) stores electrical energy and discharges it when required to support site operations. A typical BESS system in Malaysia includes battery modules, power conversion systems (PCS), an Energy Management System (EMS), monitoring platforms, and integrated safety systems that work together to optimize energy usage and load management.
In Malaysia, BESS is used to reduce Maximum Demand charges through peak shaving, increase solar self-consumption, manage electricity demand and improve operational flexibility. BESS solutions are commonly integrated into industrial solar projects where Maximum Demand (MD) charges can account for approximately 45% of total electricity costs. By intelligently managing demand patterns and reducing peak demand, BESS helps businesses lower electricity bills.
Our Solutions
How Does BESS Work with Solar?
A Battery Energy Storage System (BESS) works alongside a solar PV system by storing excess solar energy and supplying it when electricity demand exceeds solar generation or when peak demand occurs.
Generate
The solar PV system generates electricity during daylight hours to supply on-site electrical loads.
Store
When solar generation exceeds on-site consumption, surplus electricity is stored in the Battery Energy Storage System for future use.
Discharge
When solar generation is insufficient or electricity demand increases, then BESS automatically discharges stored energy to reduce grid consumption and support peak shaving.
Monitor and Optimise
The Energy Management System (EMS) continuously monitors solar generation, battery performance, and site electricity demand. Intelligent charging and discharging strategies help optimise energy usage, reduce Maximum Demand (MD), and maximise overall system performance.
Our Benefitd
What Are the Benefits of a BESS System?
Reduce Peak Demand
Lower Maximum Demand (MD) charges by discharging stored solar energy during periods of peak electricity consumption, helping reduce electricity costs.
Optimise Energy Management
Gain greater control over energy usage by intelligently scheduling battery charging and discharging based on operational schedules and demand profiles.
Enhance Energy Resilience
Provide backup solar power for selected critical loads when integrated with the appropriate system design, controls and backup configuration.
Support Sustainability Goals
Increase renewable energy utilisation, reduce carbon emissions, and support corporate sustainability and ESG objectives.
Support Future Energy Demand
Deploy BESS alongside new solar PV installations or integrate it with existing systems. Scalable capacity allows the system to adapt to future operational growth and evolving energy requirements.
