Tenaga Nasional Berhad (TNB) has announced the Automatic Fuel Adjustment (AFA) rate for the month of September 2025 is set at -RM1.10/kWh from -RM1.45/kWh in August 2025. The AFA replaces the previous Imbalance Cost Pass-Through (ICPT) and is automatically calculated as either a surcharge or discount of up to 3 sen/kWh depending on fuel prices – this is revised monthly. Introduced as part of TNB’s Electricity Tariff Restructuring that took effect from July 1, 2025, the AFA is one of five components or “charges” used to calculate your electricity bill. Here’s the overview: Generation charge: 27.03 sen/kWh for total consumption of 1,500 kWh and below per month or 37.03 sen/kWh for total consumption more than 1,500 kWh per month. This covers the actual cost of generating electricity from power plants. Capacity charge: 4.55 sen/kWh. This covers the cost of maintaining sufficient electricity supply capacity. Network charge: 12.85 sen/kWh. This covers the cost of operating and maintaining the grid and the local network to deliver electricity. Retail charge: RM10/month; waived for total consumption of 600 kWh and below a month. This is a fixed cost for metering, billing and customer service. AFA: -RM1.45 for the month of September 2025; waived for total consumption of 600 kWh and below a month. You can use our TNB Bill Calculator tool to get a rough estimate on how much your electricity bill will be for the month. Essentially, if you use over 1,500 kWh a month, you add the generation, capacity and network charges (totalling 54.43 sen/kWh) to retail charge (RM10) and the AFA (-RM1.45 discount for September 2025). Alternatively, if your usage is below 1,500 kWh a month, it’s 44.43 sen/kWh plus the retail charge and AFA. For total consumption of 600 kWh and below a month, it would be 44.43 sen/kWh. Domestic consumers who use less than 1,000 kWh a month can enjoy a discount called ‘Insentif Cekap Tenaga’ or ‘Energy Efficiency Incentive’. The discount provided is relative to consumption (the more the usage, the lesser the incentive), with the maximum discount being 25 sen/kWh. This table shows the amount of discount you are entitled to depending on your usage: Domestic users that have smart meters also have option to enter the Time of Use (ToU) scheme, allowing them to change their electricity usage pattern and take advantage of lower tariff rate during off-peak hours to enjoy savings on their monthly bill. The scheme has two time zones, with off-peak timings being from 10pm to 2pm from Monday to Friday and throughout the day (24 hours) for weekends. Peak hours are from 2pm to 10pm on weekdays. Here are the energy charges under this scheme:
