Designed for maximum demand shaving, a Battery Energy Storage System (BESS) helps manage energy usage by:
Storing excess solar or off-peak energy
Automatically releasing energy when demand exceeds the set limit
Reducing peak load usage in real time
For cost control, reliability, and energy independence, BESS optimises how and when energy is used.
What Is a Battery Energy
Storage System (BESS)?
A Battery Energy Storage System (BESS) integrates:
Solar systems
Smart battery technology
Energy Management System (EMS)
Together, they enable energy to be stored during low-cost or high-generation periods and released during peak demand or emergencies—giving you full control over when and how energy is used.
How BESS Helps Your Business in Malaysia
Reduce Maximum Demand (MD) Charges
BESS discharges stored energy during peak demand periods, reducing dependence on the grid and lowering MD charges. This is especially valuable for facilities with high or fluctuating energy loads.
Store Excess Solar Energy & Increase ROI
Solar panels often generate surplus energy during the day. BESS efficiently captures this excess power and supplies it later, improving solar utilisation and accelerating return on investment.
Protect Against Rising Electricity Tariffs
By using stored energy during high-tariff periods, BESS effectively helps stabilise long-term energy costs and reduces exposure to future tariff increases while improving overall energy cost resilience.
Improve Energy Reliability and Resilience
During power outages or voltage instability, BESS automatically and seamlessly switches to backup mode, ensuring uninterrupted operations and effectively protecting sensitive equipment.
Optimise Energy Usage with Smart EMS
An intelligent Energy Management System (EMS) analyses real-time load data and forecasts to automatically control charging and discharging, ensuring optimal efficiency without manual intervention.

Malaysia’s evolving electricity tariff structure means that even short peak-load spikes can significantly increase monthly bills. While standalone solar systems help reduce overall energy consumption, they are unable to manage peak demand effectively.
Battery Energy Storage Systems (BESS) address this gap by enabling peak shaving to reduce maximum demand costs, supporting smarter energy scheduling, and providing greater independence from the grid.
Why do businesses need Battery Energy Storage Systems (BESS)?
Why do businesses need Battery Energy Storage Systems (BESS)?
Businesses need Battery Energy Storage Systems (BESS) to better manage electricity costs and energy demand under evolving tariff structures. While solar systems reduce overall consumption, BESS helps control peak demand by storing energy and releasing it during high-load periods, reducing maximum demand charges, improving energy efficiency, and increasing independence from the power grid.
What is Maximum Demand (MD) in electricity billing?
What is Maximum Demand (MD) in electricity billing?
Maximum Demand (MD) refers to the highest level of electrical power (measured in kW) that a facility draws from the grid at any single moment within a billing month. TNB uses this peak value to calculate MD charges, meaning even a short power spike—such as running multiple high-power machines at once—can increase the entire month’s electricity cost.
With rising MD charges under the revised tariff structure, managing peak demand has become increasingly important for businesses to control energy expenses.
