What is the AFA rate for November 2026?
The Energy Commission (Suruhanjaya Tenaga, or ST) set the AFA rate for 1 to 30 November 2026 at RM0.0360 per kWh, equivalent to a surcharge of 3.60 sen/kWh. The rate is almost unchanged from October’s 3.61 sen/kWh.
ST’s monthly AFA rate page lists the November rate and explains that the adjustment reflects changes in electricity generation costs. The announcement was issued on 30 October 2026.
How much could the surcharge add to a bill?
For customers whose usage is subject to AFA, the November rate works out to RM0.036 for each kWh. The examples below show the AFA amount alone, before other charges, taxes or rebates:
| Monthly usage subject to AFA | Estimated November AFA |
|---|---|
| 300 kWh | RM10.80 |
| 500 kWh | RM18.00 |
| 1,000 kWh | RM36.00 |
These are simple calculations using the published AFA rate multiplied by the stated electricity use. Your actual bill may differ because eligibility, billing period and other bill components affect the amount payable. TNB’s bill calculator can help estimate energy charges.
Expert tip: Compare the kWh shown on your bill with the billing period before comparing the AFA amount month to month. A different billing period or level of usage can change the total.
Who is exempt from AFA?
Domestic customers using 800 kWh or less per month are exempt from AFA, the RM10 monthly retail charge and the 8% service tax for electricity use from 1 September to 31 December 2026. TNB announced the temporary protection after the government raised the threshold from 600 kWh.
The exemption applies to eligible domestic accounts. Check your bill or contact TNB if you are unsure how your account’s usage and billing period affect the charges shown.
For the measure’s terms, see TNB’s announcement on the 800 kWh protection threshold.
What is AFA and why does it change?
AFA is a monthly adjustment to electricity generation costs. It can appear as a surcharge when relevant costs are above the baseline, or as a rebate when they are below it. ST says the calculation takes account of factors such as coal and natural gas prices, foreign exchange rates and adjustments between projected and actual costs.
AFA replaced the Imbalance Cost Pass-Through (ICPT) mechanism when the revised electricity tariff structure took effect on 1 July 2025. For more detail, refer to ST’s AFA information page and Single Buyer’s AFA FAQ.
Common mistake: Treating the AFA rate as the full electricity tariff. It is one adjustment on the bill; other tariff components and applicable charges still matter.
What should customers check?
- Check the billing period and total kWh shown on your TNB bill.
- Look for the AFA line item and compare its rate with the applicable monthly notice.
- If you are a domestic customer using 800 kWh or less, check that the temporary exemption is reflected for eligible usage through December 2026.
- Use TNB’s bill calculator for an estimate, then refer to your issued bill for the final amount.
What the November AFA rate means
The AFA rate is +3.60 sen/kWh for November 2026, marginally lower than October’s rate. Eligible domestic customers at or below 800 kWh a month remain protected from AFA, the retail charge and service tax through December 2026. Check the rate and exemption details against your own bill.
