TNB Tariff A — How Malaysian Electricity Billing Works

TNB uses a progressive tariff — the more electricity you use, the higher the rate per kWh. This means reducing usage from 400 kWh to 300 kWh saves significantly more than reducing from 200 kWh to 100 kWh.

⚡ The 300 kWh Threshold

Usage jumps from 33.4 sen/kWh to 51.6 sen/kWh at the 301st kWh — a 54% increase. Keeping monthly usage under 300 kWh can save RM40–80/month for average households.

Frequently Asked Questions

How is TNB electricity bill calculated in Malaysia?
TNB uses tiered tariff for residential: first 200 kWh at RM0.218/kWh, next 100 kWh (201–300) at RM0.334/kWh, next 300 kWh (301–600) at RM0.516/kWh, above 600 kWh at RM0.546/kWh. Plus minimum charge RM3/month. Air-conditioning is typically the largest consumer (40–60% of bill).
How can I reduce my TNB electricity bill in Malaysia?
Key savings: set air-cond to 24–25°C (each degree saves ~3%), use inverter air-cond (40–50% more efficient), replace bulbs with LED, unplug standby appliances (phantom load 5–10%), wash clothes in cold water. Target under 200 kWh/month for lowest tier rate.
What is ICPT on TNB bill?
ICPT (Imbalance Cost Pass-Through) adjusts electricity tariff every 6 months based on fuel costs. Positive ICPT = surcharge. Negative ICPT = rebate. Currently (2024–2025) residential customers receive 1 sen/kWh rebate. ICPT is approved by the Energy Commission Malaysia.
How do I read my TNB meter in Malaysia?
Analog meter: read 5-digit dials left to right. Subtract previous reading = kWh used. Digital meter: displays kWh directly. Smart meter (AMI): TNB reads remotely. Check TNB MyElectric app or myTNB portal for real-time usage tracking. Estimated bills issued when meter is not read.
