TNB AFA Rate August 2026 Set at +3.80 sen/kWh
What Is the TNB AFA Rate?
The TNB AFA (Imbalance Cost Pass-Through) rate is a quarterly adjustment applied to electricity tariffs in Malaysia by Tenaga Nasional Berhad (TNB). It reflects changes in fuel and generation costs. For August 2026, the AFA rate has been set at +3.80 sen/kWh, meaning an additional 3.80 sen per kilowatt-hour will be added to the base tariff for all consumer categories.
The TNB AFA rate for August 2026 is +3.80 sen/kWh, adding RM0.038 per unit of electricity consumed.

How Does the August 2026 AFA Rate Affect My Electricity Bill?
The AFA rate is added to the base tariff on a per-kWh basis. For a household consuming 300 kWh per month, the additional charge is 300 × RM0.038 = RM11.40. This is on top of the existing base tariff and any other surcharges. The adjustment applies to all meter readings taken during August 2026.
For a typical Malaysian household using 300 kWh monthly, the August 2026 AFA rate adds RM11.40 to the electricity bill.
“The TNB AFA rate for August 2026 has been set at +3.80 sen/kWh, reflecting adjustments in fuel costs and generation mix,” reported Paul Tan’s Automotive News. — paultan.org, 1 August 2026
What Factors Led to This Adjustment?
The AFA rate is determined by the Imbalance Cost Pass-Through (ICPT) mechanism, which recovers or rebates the difference between actual fuel and generation costs and the benchmark used in the base tariff. For August 2026, higher global coal and gas prices, combined with a shift in generation mix, contributed to the +3.80 sen/kWh increase. The Energy Commission reviews these costs quarterly.
The +3.80 sen/kWh AFA rate is driven by higher fuel costs and changes in Malaysia’s generation mix during the preceding quarter.
How Does This Compare to Previous AFA Rates?
In the May 2026 cycle, the AFA rate was +2.50 sen/kWh. The August 2026 rate of +3.80 sen/kWh represents an increase of 1.30 sen/kWh. Over the past year, AFA rates have fluctuated between -1.00 sen/kWh and +4.20 sen/kWh, depending on global energy markets. The current rate is among the higher adjustments seen in 2026.
The August 2026 AFA rate of +3.80 sen/kWh is 1.30 sen/kWh higher than the previous quarter’s rate of +2.50 sen/kWh.
Who Is This For in Malaysia?
This adjustment affects all TNB customers in Peninsular Malaysia, including households in high-rise condominiums, landed properties, small businesses, and industrial users. For compact urban living (e.g., KL condos with air conditioning), the impact is more noticeable due to higher per-capita consumption. Users on the Lifeline Tariff (first 200 kWh) still pay the base rate, but the AFA surcharge applies to all consumption above zero.
Every TNB customer in Peninsular Malaysia, from apartment dwellers to factory operators, will see the +3.80 sen/kWh AFA surcharge on their August 2026 bill.
Common Questions
How is the AFA rate calculated?
The AFA rate is derived from the ICPT mechanism, comparing actual fuel and generation costs against the benchmark. The Energy Commission approves the rate quarterly based on TNB’s submission.
Will this affect the base tariff?
No. The base tariff remains unchanged. The AFA is a separate surcharge that fluctuates quarterly. The base tariff is reviewed every three years by the government.
When does the new rate take effect?
The +3.80 sen/kWh AFA rate applies to all electricity consumption recorded from 1 August 2026 until the next quarterly review in November 2026.
