Malaysia's Automatic Fuel Adjustment hits sixth straight month of surcharges; January threatens 7.59 sen/kWh as subsidies end

The Energy Commission set Malaysia's Automatic Fuel Adjustment rate for October 2026 at a surcharge of 3.61 sen per kilowatt-hour, continuing a streak of cost pressures that began in July 2025 when TNB replaced its previous tariff mechanism with a monthly fuel-tracking model ^[1]. For six months running, that adjustment has been positive, meaning households and businesses are paying a markup above the baseline tariff to cover global fossil fuel costs. The October rate, while marginally lower than September's 3.67 sen/kWh, arrives as TNB's three-month outlook tilts sharply upward: +4.27 sen/kWh forecast for November, +4.46 sen/kWh for December, and a projected 7.59 sen/kWh for January 2027 ^[1]. If that January figure materializes, it will be the highest AFA surcharge since the mechanism's introduction.

The mechanism at work is a direct pass-through: when global gas, coal, and oil prices exceed the baseline costs baked into the tariff, customers pay the difference as an explicit surcharge added to the bill. The baseline prices themselves are set below current global markets (Tier 2 gas base: 46 RM/mmBTU against October's spot price of 58.92 RM/mmBTU; coal base: 97 USD/MT against 123.76 USD/MT) ^[1], meaning the surcharge is structural, not temporary. The surcharge is spread across the entire customer base, but protection is means-tested: until 31 December 2026, domestic users consuming 800 kWh per month or less are exempted from the AFA surcharge, the 10 RM retail charge, and the Sales and Service Tax ^[4]. That threshold was raised from 600 kWh in September specifically because haze and hotter weather pushed many households over the old limit ^[7].

Here is what ends at midnight on 31 December: the 800 kWh protection reverts to 600 kWh, meaning households consuming between 600 and 800 kWh per month will suddenly owe the full AFA surcharge, the retail charge, and SST, all at once. A household using 750 kWh in January will see the January AFA alone add 5.69 RM (about 1.36 USD) to that month's bill ^[1], on top of the restored retail charge and SST. The government's framing, presented in September, was that the expanded protection was a temporary cost-of-living relief ^[7]; no permanent successor mechanism has been announced, and the outlook documents show TNB simply reverting to the lower threshold. The political economy is clear: the subsidy is a transfer, visible in the budget, while tariff surcharges are presented as automatic and neutral.

This is the mechanism that separates Malaysia from the disconnection-for-poverty regimes common in the United States. Europe's response to fuel price volatility and energy poverty has been different: France renationalized EDF in 2023 and deployed a tariff shield (bouclier tarifaire) to cap household rates through the 2022, 23 crisis, preserving affordability as a policy goal rather than a residual of fuel markets ^[3]. Spain's bono social, Portugal's tariff schemes, and EU-wide protections restrict disconnection of vulnerable households, treating the power connection as closer to a right than a contract. Malaysia's AFA and subsidy dance, temporary relief followed by cliff edges, leaves the poorest households exposed to month-to-month volatility without structural protection. The United States, by contrast, does not even track disconnections for non-payment at the national level, though studies estimate roughly three million annually; there is no federal protection floor and no automatic shelter from fuel-price pass-throughs.

The alternative is simple and operates at scale elsewhere: set a baseline tariff that reflects an accepted cost of service plus a modest margin, and commit to absorbing fuel-price volatility through budgeted subsidy or rate-smoothing mechanisms rather than making household bills a monthly meter of global commodity prices. Malaysia's Single Buyer structure (the government-owned entity that purchases power wholesale and sells to TNB) could be required to hold a stabilization reserve, funded through the annual budget, that caps the monthly AFA at a fixed ceiling for domestic users below a consumption threshold. The surcharge visible on the October bill, RM391 million (about 84 million USD), already shows the scale of cost-shifting; a permanent subsidy, transparently budgeted, would replace it and give households certainty. Such a move would cost less than the temporary protection mechanism (which required no legislative change) and would silence the cliff-edge threat that arrives in January.
