IMPORTANT NOTICE FOR INDUSTRIAL BUSINESS OWNERS

Your TNB Tariff Changed on 1 July 2025. Here's What You Need to Know!

If your factory or industrial premise was previously billed under Tariff D (Low Voltage Industrial), your account has now been shifted to the Non-Domestic Low Voltage (LV) category under the new Regulatory Period 4 (RP4) electricity tariff structure.

What Has Changed?

Old Tariff D:

Energy Charge (sen/kWh)
Maximum Demand Charge (RM/kW per month) – based on your highest power draw
No itemised breakdown – simpler structure

New Tariff (Non-Domestic Low Voltage):

No More Maximum Demand Charges
Charges are now itemised into:

• Energy Charge: usage-based (sen/kWh)
• Capacity Charge: based on how much load you use
• Network Charge: covers distribution costs
• Retail Charge: for customer services
• AFA: automatic fuel adjustment, replacing ICPT

Optional Time-of-Use (ToU) pricing may apply — peak vs off-peak charges

What This Means for You

Some businesses may benefit - no more MD charges, lower demand hours
Others may see higher bills - especially those with high or inefficient load usage during peak periods

The new structure rewards energy efficiency and peak load management.
