Breaking News: Tenaga Nasional Berhad (TNB) Reveals January 2026 Automatic Fuel Adjustment (AFA) Rate at an Impressive -4.99 sen/kWh
In January 2026, Tenaga Nasional Berhad (TNB), Malaysia’s primary electricity utility provider, announced a notable Automatic Fuel Adjustment (AFA) rate of -4.99 sen per kilowatt-hour (kWh) for consumers in Peninsular Malaysia. This negative AFA rate represents a rebate on electricity tariffs, reflecting a decrease in fuel costs that is passed on directly to consumers, effectively reducing their electricity bills for the month. The AFA system, implemented from July 2025, replaced the previous semiannual Imbalance Cost Pass-Through (ICPT) mechanism with monthly tariff adjustments to better mirror fluctuations in global fuel prices and foreign exchange rates, while capping monthly changes at ±3 sen/kWh to safeguard consumers from sudden price shocks.
The January 2026 rebate follows a broader tariff restructuring under Malaysia’s Fourth Regulatory Period (RP4), which introduced a higher base tariff and simplified consumption tiers to promote energy efficiency and cost-reflective pricing. Households consuming 600 kWh or less monthly are exempt from retail and AFA charges, benefiting from stable base rates, while higher consumption brackets incur dynamic charges reflecting real-time fuel cost movements. This new tariff framework encourages adoption of energy management strategies among commercial and industrial users, including battery storage and solar power, aligning with national goals to balance rising energy costs with sustainability.
The shift to the AFA mechanism and the resulting tariff changes have elicited mixed responses. While many residential consumers welcome the rebates and greater tariff transparency, business groups express cautious optimism, urging stable tariffs to mitigate operational cost pressures amid inflation concerns. Regulators emphasize the AFA’s role in fostering a fairer, more responsive electricity pricing system, supporting Malaysia’s energy transition policies aimed at increasing renewable energy share to 70% by 2050 and ensuring a sustainable energy future.
Despite these advances, challenges remain in managing fuel price volatility and expanding renewable infrastructure. The monthly AFA adjustments provide consumers with more immediate relief or surcharges linked to fuel markets, but also require ongoing regulatory oversight to balance market responsiveness with consumer protection. Malaysia’s continued policy support and regulatory refinement aim to sustain momentum toward a greener, more resilient energy sector while addressing affordability and competitiveness concerns.
Background
Tenaga Nasional Berhad (TNB), the main electricity utility provider in Peninsular Malaysia, implemented significant changes to its electricity tariff structure starting 1 July 2025. This overhaul marked a transition from the previous Imbalance Cost Pass-Through (ICPT) mechanism, which adjusted fuel costs biannually under the Incentive-Based Regulation (IBR) framework, to a new Automatic Fuel Adjustment (AFA) system that updates tariffs on a monthly basis in response to fluctuations in global fuel prices and foreign exchange rates.
The AFA system aims to provide a more responsive and cost-reflective energy pricing model by allowing monthly rebates when fuel prices decline and surcharges when they rise, with changes capped at ±3 sen per kWh to prevent sudden tariff spikes. This shift supports the Malaysian government’s objectives of balancing rising global energy costs with ongoing efforts toward renewable energy adoption and sustainability.
Under the new tariff framework, commercial and industrial (C&I) users are particularly impacted, encouraging businesses to adopt energy management strategies such as battery energy storage systems (BESS) and solar power solutions to reduce charges and mitigate fluctuations caused by the AFA mechanism. These reforms are part of a broader regulatory environment in Malaysia designed to promote transparency, competitiveness, and consumer protection while fostering innovation and sustainable growth in the energy sector.
January 2026 AFA Rate Announcement
In January 2026, Tenaga Nasional Berhad (TNB) announced an Automatic Fuel Adjustment (AFA) rate of -4.99 sen per kWh, reflecting a rebate on electricity tariffs for consumers in Peninsular Malaysia. This negative AFA rate indicates a reduction in fuel costs that is passed on to customers, effectively lowering their electricity bills for the month.
For households consuming 600 kWh or less per month, the retail charge and AFA adjustments are waived, meaning such low-consumption users pay only the base rate of 44.43 sen per kWh without additional fees or rebates. For usage between 601 kWh and 1,500 kWh, the tariff comprises the base charge plus the retail fee (RM10/month) and the AFA discount. Consumers exceeding 1,500 kWh are charged an aggregated rate including generation, capacity, network charges, retail charge, and the AFA adjustment.
This rebate for January 2026 follows a trend of fluctuating AFA rates in 2025, such as the -8.91 sen per kWh discount recorded in November 2025 and smaller rebates or zero adjustments in preceding months, reflecting ongoing shifts in global fuel prices and currency values. The Energy Commission’s adoption of this monthly adjustment process aims to provide consumers with more predictable and fair pricing, while also encouraging energy efficiency and consumption management among households and businesses alike.
Factors Influencing the January 2026 AFA Rate
The Automatic Fuel Adjustment (AFA) rate for January 2026 was set at -4.99 sen per kWh, a decrease from the -6.42 sen per kWh rate recorded in December 2025. This negative AFA rate reflects a fuel cost rebate applied to consumers, demonstrating the mechanism’s role in adjusting tariffs in line with fluctuations in global fuel prices. The AFA replaced the previous Imbalance Cost Pass-Through (ICPT) system starting from July 1, 2025, and is designed to be recalculated monthly by Malaysia’s Energy Commission (Suruhanjaya Tenaga).
Several factors influenced the determination of the January 2026 AFA rate. Firstly, the global fuel price trends directly affect the AFA, as the system provides rebates when prices fall and surcharges when prices rise, allowing electricity tariffs to more accurately reflect real-time fuel costs. The reduction in fuel costs leading up to January 2026 contributed to the negative AFA rate, indicating a discount for consumers. This dynamic adjustment mechanism ensures that tariff changes remain responsive to the volatile nature of fossil fuel markets, unlike the previous ICPT system that adjusted costs semi-annually.
Additionally, the tariff restructuring introduced alongside the AFA implementation included a revision of the base tariff and simplification of consumption tiers. The base tariff was adjusted to 45.40 sen per kWh from the previous 39.95 sen per kWh, with consumption charges consolidated into two tiers: 27.03 sen per kWh for the first 1,500 kWh and 37.03 sen per kWh thereafter. This restructuring supports the AFA’s goal of promoting energy efficiency while maintaining a transparent pricing framework aligned with Malaysia’s broader energy reform agenda.
Furthermore, the waiver of the AFA charge for households consuming 600 kWh or less per month serves as an incentive for reduced consumption, aligning with national objectives to encourage energy conservation and support vulnerable consumers. This rebate mechanism complements the monthly AFA adjustments and underpins the country’s commitment to a more sustainable and equitable energy system.
Finally, Malaysia’s energy transition policies, including the National Energy Transition Roadmap (NETR) and initiatives to increase renewable energy penetration, indirectly influence fuel price volatility and consequently the AFA rate. As the country aims for 70% renewable energy generation by 2050, the dependency on fossil fuels is expected to decrease, potentially moderating future fluctuations in the AFA and stabilizing electricity tariffs over the long term.
Regulatory Framework
The regulatory framework governing Tenaga Nasional Berhad (TNB) and Malaysia’s energy sector is designed to balance effective oversight with the promotion of innovation and business growth. Regulatory bodies in Malaysia play a crucial role in developing and enforcing rules that govern operations within various industries, including energy. This proactive approach by the government aims to maintain competitiveness and safeguard consumer and investor interests while fostering a conducive environment for innovation.
Central to the energy sector’s regulatory framework is the Energy Commission (Suruhanjaya Tenaga, ST), which oversees tariff structures and pricing mechanisms. Recently, the Energy Commission announced an updated tariff calculation method, known as the Automatic Fuel Adjustment (AFA), which will be applied during the Fourth Regulatory Period (RP4) from July 2025 to the end of 2027. The AFA replaces the previous Imbalance Cost Pass-Through (ICPT) mechanism and serves as a monthly adjustment to electricity bills to reflect fluctuations in global fuel prices and currency exchange rates.
The AFA is automatically calculated as either a surcharge or a discount of up to 3 sen per kWh, with any changes beyond this cap requiring cabinet approval. This market-linked mechanism aims to more accurately reflect generation costs, promoting cost-reflective pricing within the energy sector. Concurrently, TNB has announced an increase in the base tariff rate for Peninsular Malaysia from 39.96 sen per kWh to 45.62 sen per kWh under RP4, signaling a decisive shift towards market-based energy pricing. This tariff revision incentivizes businesses to adopt energy management strategies, such as battery energy storage systems (BESS) and solar power, to remain competitive and mitigate fluctuations in monthly AFA charges.
Impact of the January 2026 AFA Rate
The Automatic Fuel Adjustment (AFA) rate for January 2026 was set at -4.99 sen per kilowatt-hour, marking a significant rebate for consumers under the new tariff restructuring that took effect in July 2025. This negative AFA rate effectively reduces the electricity cost for eligible households, particularly benefiting those with monthly consumption of 600 kWh or below, for whom the retail and AFA charges are waived entirely.
Domestic consumers using less than 1,000 kWh per month can further capitalize on the ‘Insentif Cekap Tenaga’ or ‘Energy Efficiency Incentive’, which provides a discount relative to their electricity usage, with a maximum rebate of 25 sen/kWh. This structure encourages energy conservation by rewarding lower consumption levels with greater discounts. Communications Minister Fahmi Fadzil highlighted that approximately 85% of residential customers are expected to see either no increase or a reduction in their electricity bills, assuming their usage remains under 1,000 kWh monthly.
The monthly adjustment mechanism of the AFA contrasts with the previous biannual ICPT system, allowing more responsive tariff changes that mirror fluctuations in global fuel prices. This responsiveness is intended to provide a fairer and more dynamic pricing structure, which can incentivize energy efficiency while maintaining financial sustainability in the energy sector. The rebate for January 2026 thus reflects a period of decreased power generation costs, providing temporary relief to consumers amidst broader concerns of rising electricity prices projected to increase by 13% to 18% by the end of 2026.
Public and Stakeholder Responses
The recent announcement of Tenaga Nasional Berhad’s (TNB) Automatic Fuel Cost Adjustment (AFA) rate for January 2026, set at -4.99 sen per kWh, has elicited varied reactions from the public and key stakeholders. Business groups, particularly representatives from the Associated Chinese Chambers of Commerce and Industry of Malaysia (ACCCIM), have expressed cautious optimism while highlighting ongoing concerns over operational costs. Mr. Ng, representing ACCCIM’s 110,000 members, urged the government to maintain electricity tariffs at current levels through 2025-2026 to alleviate financial pressures on businesses and mitigate inflationary impacts stemming from increased operating expenses.
Industry analysts and energy experts emphasize the importance of the tariff revisions as part of Malaysia’s broader shift toward cost-reflective energy pricing. The updated tariff structure, including the replacement of the Maximum Demand charge with Capacity and Network Charges and the implementation of a market-linked AFA mechanism, aims to more accurately reflect actual grid usage and generation costs. This approach is seen as encouraging energy efficiency and investment in energy storage and renewable generation technologies among commercial users.
From the regulatory perspective, the Energy Commission’s adoption of a capped monthly adjustment in the AFA mechanism—limited to 3 sen per kWh—has been noted as a balanced measure that protects consumers from excessive fluctuations while maintaining responsiveness to market conditions. This regulatory prudence aligns with Malaysia’s overall framework of promoting business growth and innovation while safeguarding consumer interests and ensuring compliance with fair market conduct practices.
Moreover, calls for collaboration among government bodies, private sectors, and civil society continue to be highlighted as essential in advancing the country’s renewable energy goals and ensuring the transition to a sustainable energy future. Stakeholders stress the need for further incentives, streamlined project approvals, and improved financing mechanisms to sustain momentum in clean energy development.
Future Outlook
Malaysia’s energy transition is expected to maintain strong momentum through 2026 and beyond, supported by robust policy initiatives and ambitious renewable energy targets. The National Energy Transition Roadmap aims for a 70 percent renewable energy (RE) mix by 2050, a goal reaffirmed in the 2026 national budget, signaling a firm commitment to a greener energy future.
A significant driver in this transition is the Large Scale Solar (LSS) program. The rollout of a combined 4GW solar capacity under the LSS5 and LSS5+ schemes is underway, with the next phase, LSS6, anticipated to launch in 2026 as outlined in Budget 2026. These projects are expected to substantially increase solar adoption, leveraging Malaysia’s abundant clean energy resources and favorable market conditions for investors.
The evolution of electricity tariff mechanisms also plays a key role in shaping the energy landscape. The introduction of the Automatic Fuel Adjustment (AFA) system in July 2025 allows for monthly tariff adjustments based on real-time fuel prices and currency fluctuations, improving cost-reflectiveness compared to the previous biannual adjustment under the Imbalance Cost Pass-Through (ICPT) system. However, monthly changes are capped at 3 sen per kWh to ensure gradual transitions and protect consumers from sudden price shocks.
Challenges remain in scaling up infrastructure to support renewable integration, including the need for accelerated grid capacity expansion and enhanced grid stability and flexibility. Financing remains a critical barrier, although Malaysia’s relatively low investment risks and government incentives—such as feed-in tariffs for up to 1 MW and net metering policies—are attracting increased domestic and foreign investments in renewable projects. Further improvements in project approval processes and financing mechanisms, including power purchase agreements and tariff structuring, are recommended to facilitate faster deployment and greater market participation.
On the regulatory front, Malaysia continues to refine its framework to balance investor interests with effective oversight. Proactive updates to regulations aim to foster innovation and maintain the country’s competitiveness in the evolving energy sector. These efforts are expected to support a smoother transition towards a more sustainable and resilient electricity system.
