TNB has announced the new electricity tariffs from July 2025. There has been a major change in how the bill is calculated for domestic users which we will be covering in this story.
There are five components or “charges” to calculating your bill:
- Generation charge – 27.03 sen/kWh for usage under 1,500 kWh a month or 37.03 sen/kWh for usage over 1,500 kWh a month. This covers the actual cost of generating electricity from power plants.
- Capacity charge – 4.55 sen/kWh. This charge is said to be for ensuring reliable supply by maintaining power plants and standby capacity.
- Network charge – 12.85 sen/kWh. This charge is for the cost of operating and maintaining the grid and the local network to deliver electricity.
- Retail charge – RM10 a month, exempted for usage under 600 kWh a month. This is a fixed cost for metering, billing and customer service.
- Automatic Fuel Adjustment (AFA) – an automatic calculation of either a surcharge or discount of up to 3 sen/kWh depending on fuel prices, revised on a monthly basis.
If you want to have a rough estimate how much your bill will be with the new tariff, use our TNB Bill Calculator tool.
Essentially, if you use more than 1,500 kWh a month, add generation + capacity + network charges together and you’re looking at a per kWh rate of 54.43 sen/kWh + RM10 + what the AFA surcharge or discount is.
If you use below 1,500 kWh a month, you pay 44.43 sen/kWh + RM10 + AFA.
There is a discount called “Insentif Cekap Tenaga” or “Energy Efficiency Incentive”. This applies for domestic users using less than 1,000 kWh a month. The discount is a downward sliding amount (the more the usage, the lesser the incentive). The maximum discount is 25 sen/kWh.
The table below shows how to calculate this discount.
There is also a new optional ToU tariff for domestic users. This is only available for smart meter users. Essentially you are given the opportunity to pay a little more for electricity during peak hours in exchange for lower electricity prices during off-peak hours.
The definition of off-peak is quite generous – it covers 24 hours during the weekends, and 12am to 2pm as well as 10pm to 12am during weekdays.
For usage below 1,500 kWh per month
For usage above 1,500 kWh per month
So if you want to save on electricity in charging your electric car at home, you could schedule your charging to begin after 10pm or during the weekends for example.
To apply to switch to ToU tariff you will have to visit the nearest Kedai Tenaga.
What do you think of the new electricity tariffs? Do you think you will save on your bill or pay more after this? Let us know in the comments.
TNB has published an estimated comparison for usage up to 900 kWh a month, which reveals a lower bill for this segment of usage. Essentially, if your bill is below RM400 now, you will probably be paying less.
If your consumption is higher than 900 kWh a month, you will have to calculate yourself to see if you will see a drop or increase in your bill. Use our TNB Bill Calculator tool.

How come the bill amount calculated using the tool is not the same as per the table provided in the article?
Domestic Bill Comparison not consistent with TNB Bill Calculator. Either calculator is wrong or comparison is misleading. My bill will increase by 21% in Jul
@paultan, Your TNB Bill Calculator provided here is incorrect and differs from the one provided by TNB on their website. Also, there is zero transparency on how TNB calculates the Energy Efficiency Incentive. Finally, the calculations become complicated when considering KWTBB and ST. TNB needs to come forward with clearer calculations.
