How Peak Shaving and Battery Storage Can Slash Your TNB Bill

Are you looking for smart ways to cut your electricity bill with Tenaga Nasional Berhad (TNB)? Businesses in Malaysia face rising energy and demand charges — but there’s good news: Peak shaving combined with Battery Energy Storage Systems (BESS) can help you save big!

What is Peak Shaving?

Peak shaving means reducing your electricity consumption during the highest demand periods — typically from 2 PM to 10 PM on weekdays, when TNB applies the highest capacity charges.

By lowering how much power you pull from the grid during these peaks, you avoid the expensive demand charges that can dominate your bill.

How Does Battery Storage Help?

Battery Energy Storage Systems are essentially big rechargeable batteries installed on-site. Here’s how they work:

• Charge the batteries during off-peak hours (like late nights or weekends when electricity is cheaper).

• Discharge during peak hours to power your operations, so you buy less electricity from TNB at expensive times.

• This reduces your measured peak demand, lowering capacity charges.

• You also gain from energy arbitrage — buying cheap electricity and using it when prices are higher.

Real Savings with BESS

For example, if your peak demand is 200 kW, and battery storage helps shave 50 kW off that peak, your monthly savings on capacity charges alone can exceed RM2,000. Plus, battery storage allows you to take advantage of Time-of-Use tariffs by charging when rates are low and discharging when rates are high — further stretching your energy budget.

Why Business Owners Should Act Now

Battery costs in Malaysia are decreasing fast. Installing a BESS system tailored to your business could pay back in under a decade through reduced energy bills and demand charges.

Moreover, new government policies encourage renewable energy and storage through programs like SELCO, creating additional incentives for businesses adopting battery storage and solar systems.
