Tenaga Nasional Berhad (TNB) has stated that the Automatic Fuel Adjustment (AFA) rate for the month of December 2025 is -6.42 sen/kWh from -8.91 sen/kWh in November 2025. The AFA, which is set by the Energy Commission (ST), 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, with any larger changes (beyond 3 sen) requiring cabinet approval.
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 rate: -6.42 sen for the month of December 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 rate (-6.42 sen/kWh discount for December 2025).
Alternatively, if your usage is below 1,500 kWh a month, it’s 44.43 sen/kWh plus the retail charge and AFA rate. For total consumption of 600 kWh and below a month, it would only be 44.43 sen/kWh – retail and AFA charges are waived.
Here’s a list of the monthly AFA rates so far in 2025:
- July 2025: 0.00 sen/kWh
- August 2025: -1.45 sen/kWh
- September 2025: -1.10 sen/kWh
- October 2025: -6.50 sen/kWh
- November 2025: -8.91 sen/kWh
- December 2025: -6.42 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.
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:
For usage of 1,500 kWh and below per month
- Peak tariff: 28.52 sen per kWh
- Off-peak tariff: 24.43 sen per kWh
For usage above 1,500 kWh per month
- Peak tariff: 38.52 sen per kWh
- Off-peak tariff: 34.43 sen per kWh

the T20 are hard hit by this high electric rate as it becomes more expensive to charge their EV at their landed home. also they t20 dont benefit from budi95 because their AMG45 or bmw M4 needs ron97 cannot use ron95 engine ping premateure detonation
Thats why T20 also have solar PV on NEM scheme to get negative or RM 10 per month electricity bill. And this is after fully charge their EVs all the time everyday.
New pricing components (effective July 1, 2025) reduced the home solar rates so dont be so happy , as homeowners are at the mercy of TnB who for sure will further lower the rates in future.
Don’t know why but my electricity bill has been increasing since TNB introduced the new structure. Has been 5-10% higher every month but my usage is below RM100
Price Hike you can is thanks to which govt and which PM ?
saga today is even cheaper than saga price during BN time (account for inflation).
budi95 today is cheaper than ron95 during BN (account for inflation).
also remember last time BN heavily taxed foreign car because wanted to protect proton from foreign competitors.
My TNB bill is still averaging less than RM30 a month after the 1/7/2025 electricity tariff restructuring as my electricity usage averages less than 150kWh per month. Those who use more than 200kWh a month most likely have to pay noticeably more after the tariff restructuring.
For 50 years Gomen BN rarely raise electricity prices. Now prices shooting up is thanks to which govt and which PM ?
but we already got cheap ron95 price RM1.99. choose which one you want, cheap petrol or cheap electric, because you cannot have both.
Fake news. RON95 petrol is at RM 2.65 unless you sell your data & votes to PH. Hell no!
All these rumors are likely started by Opposition macai. Dumb people would believe anything.
actual in reality-
Before June 2006, TNB’s average electricity tariff was at 23.50 sen/kWh.
In June 2006, it increased to 26.32 sen/kWh.
In July 2008, it increased to 31.31 sen/kWh.
In March 2009, it increased to 32.50 sen/kWh.
In June 2011, it increased to 33.54 sen/kWh.
In January 2014, it increased to 38.53 sen/kWh.
The BN gomen was in charge during those years.
You are the one triggering your own fake news. Citizen’s personal data is already with JPN & JPJ regardless of who is administering the central gomen. And voter data is handled only by the election commission. You are just unhappy that the present administration has managed unlock the potential of the MyKad electronic chip so that only the real Malaysian citizens with driving licences can buy RON95 at RM1.99/litre while foreigners have to buy at RM2.60+ per litre.
