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.
