TNB has announced the brand new electricity tariffs from July 2025. There was a significant change in how the bill is calculated for domestic users which we will probably be covering on 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.
- Capability charge – 4.55 sen/kWh. This charge is alleged to be for ensuring reliable supply by maintaining power plants and standby capability.
- Network charge – 12.85 sen/kWh. This charge is for the price 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 can be a fixed cost for metering, billing and customer support.
- Automatic Fuel Adjustment (AFA) – an automatic calculation of either a surcharge or discount of as much as 3 sen/kWh depending on fuel prices, revised on a monthly basis.
Essentially, when you use greater than 1,500 kWh a month, add generation + capability + network charges together and also you’re a per kWh rate of 54.43 sen/kWh + RM10 + what the AFA surcharge or discount is.
In case you use below 1,500 kWh a month, you pay 44.43 sen/kWh + RM10 + AFA.
Example of bill calculation
You may also notice in the instance bill above that there’s a discount called a “Energy Efficiency Incentive”. This is applicable for domestic users using lower than 1,000 kWh a month. The discount is a downward sliding amount (the more the usage, the lesser the inducement). The utmost discount is 25 sen/kWh.
Optional peak/off-peak ToU tariff for domestic
There’s also a brand new optional ToU tariff for domestic users. This is just available for smart meter users. Essentially you’re given the chance to pay somewhat more for electricity during peak hours in exchange for lower electricity prices during off-peak hours.
The definition of off-peak is kind of generous – it covers 24 hours throughout the weekends, and 12am to 2pm in addition to 10pm to 12am during weekdays.
For usage below 1,500 kWh per thirty days
- Peak tariff – 28.52 sen per kWh
- Off-peak tariff – 24.43 sen per kWh
For usage above 1,500 kWh per thirty days
- Peak tariff – 38.52 sen per kWh
- Off-peak tariff – 34.43 sen per kWh
So if you wish to save on electricity in charging your electric automobile at home, you could possibly schedule your charging to start after 10pm or throughout the weekends for instance.
What do you’re thinking that of the brand new electricity tariffs? Do you’re thinking that you’ll save in your bill or pay more after this? Tell us within the comments.
Will I pay roughly for my TNB bill?
TNB has published a comparison for usage as much as 900 kWh a month, which reveals a lower bill for this segment of usage. Essentially, in case your bill is below RM400 now, you will likely be paying less.
In case your consumption is higher than 900 kWh a month, you should have to calculate yourself to see when you will see a drop or increase in your bill.
