From Tariff D to Non-Domestic LV: Understanding the New TNB Structure
๐ข 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?
๐งพ Old Tariff D:
โ Energy Charge (sen/kWh)
โ Maximum Demand Charge (RM/kW per month) – based on your highest power draw
โ No itemised breakdown – simpler structure
๐ New Tariff (Non-Domestic Low Voltage):
โ No More Maximum Demand Charges
โ 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
๐ Optional Time-of-Use (ToU) pricing may apply — peak vs off-peak charges
โ What This Means for You
โ Some businesses may benefit - no more MD charges, lower demand hours
โ Others may see higher bills - especially those with high or inefficient load usage during peak periods
๐ก The new structure rewards energy efficiency and peak load management.
