Malaysia’s electricity tariff structure isn’t static – it has changed several times over the past decade:
- Before 2014: Flat tariff, rarely reviewed, not responsive to fuel cost changes.
- 2014: Introduction of tiered tariff structure and the ICPT mechanism to pass fuel cost fluctuations to consumers more transparently.
- 2020-2021: The FiT solar incentive scheme closed to new registrations; NEM became the main solar incentive pathway.
- 1 July 2025 (RP4): Base tariff rose 14.2%, ICPT was replaced by AFA (monthly review), and the optional ToU scheme was expanded to all users.
- 1 January 2026: Solar ATAP replaced NEM as the main solar incentive scheme.
Overall trend: base tariffs rise gradually in line with infrastructure costs and the national energy transition, while the adjustment mechanism (ICPT/AFA) is reviewed more frequently to reflect real costs more accurately.
TNB Domestic (Residential) Tariff Structure (RP4)
Starting 1 July 2025, Peninsular Malaysia’s base electricity tariff rose 14.2% (from 39.95 sen/kWh under RP3 to an average 45.62 sen/kWh under RP4). The domestic tariff structure is now broken down into these components:
| Component | Rate |
|---|---|
| Generation Charge (<=1,500 kWh) | 27.03 sen/kWh |
| Generation Charge (>1,500 kWh) | 37.03 sen/kWh |
| Capacity Charge | 4.55 sen/kWh |
| Network Charge | 12.85 sen/kWh |
| Retail Charge | RM10/month (waived if <=600 kWh) |
| Estimated total (before AFA/EEI) | ~44.43 sen/kWh (<=1,500 kWh) / ~54.43 sen/kWh (>1,500 kWh) |
Source: Official TNB Tariff Schedule, Suruhanjaya Tenaga (Energy Commission) – Peninsular Malaysia, effective 1 July 2025 to 31 December 2027. View official rate schedule.
On top of this, there’s the Energy Efficiency Incentive (EEI) – a tiered rebate offering up to 25 sen/kWh discount for the first 200 kWh, tapering gradually to zero above 1,000 kWh usage. This means low-usage households (under 600 kWh) actually pay a much lower effective rate than the “estimated total” figures above suggest.
Worked Example: Household Using 900 kWh/Month
| Component | Calculation | Amount |
|---|---|---|
| Generation Charge (900 kWh x 27.03 sen) | 900 x RM0.2703 | RM243.27 |
| Capacity Charge (900 kWh x 4.55 sen) | 900 x RM0.0455 | RM40.95 |
| Network Charge (900 kWh x 12.85 sen) | 900 x RM0.1285 | RM115.65 |
| Retail Charge | – | RM10.00 |
| Gross total (before AFA/EEI) | – | ~RM409.87 |
The actual figure on your bill will differ slightly after subtracting EEI and adding/subtracting that month’s AFA. Use the calculator below for an estimate closer to your own situation.
The RM10/month Retail Charge is automatically waived for anyone using 600 kWh or less per month – so smaller households actually pay a lower effective rate than the table above shows. Want the full breakdown of how this is calculated together with AFA and SST? See our TNB bill calculator guide.
From 1 September to 31 December 2026, the Government temporarily raised this exemption threshold from 600 kWh to 800 kWh/month – covering roughly 90% of TNB’s domestic customers. Households using 800 kWh or less during this window are fully exempt from AFA charges, the 8% SST, and the RM10 Retail Charge, and TNB applied a pro-rata credit for September usage on October 2026 bills. This is confirmed as a temporary measure only – TNB has not said whether it will extend past 31 December 2026, so budget as if the threshold reverts to 600 kWh from January 2027 unless an extension is announced.

TNB Commercial & Industrial Tariff Structure
Tariffs for businesses (C1, C2 categories) and industry (E1, E2, E3 categories) use a different structure from domestic – typically including a separate Maximum Demand (MD) charge on top of the energy charge (kWh), and varying by connection voltage (low/medium/high). Broadly:
- C1/C2 (Commercial): for shops, offices, restaurants – low voltage connection, usually no separate MD charge for small demand.
- E1-E3 (Industrial): for factories – medium/high voltage connection, MD charge based on the highest demand (kW) over any 30-minute period in the month, separate from the energy charge (kWh).
Under RP4 (effective 1 July 2025 to 31 December 2027), Non-Domestic tariffs are broken down by connection voltage (Low/Medium/High) and by scheme (General or Time-of-Use). Here are the full base rates:
Low Voltage (Commercial – Tariff B/C1, Industrial – Tariff D)
| Component | General | ToU – Peak | ToU – Off-Peak |
|---|---|---|---|
| Energy Charge | 27.03 sen/kWh | 28.52 sen/kWh | 24.43 sen/kWh |
| Capacity Charge | 8.83 sen/kWh | 8.83 sen/kWh | 8.83 sen/kWh |
| Network Charge | 14.82 sen/kWh | 14.82 sen/kWh | 14.82 sen/kWh |
| Retail Charge | RM20/month | RM20/month | RM20/month |
Medium Voltage (Commercial – Tariff C1/C2, Industrial – Tariff E1/E2)
| Component | General | ToU – Peak | ToU – Off-Peak |
|---|---|---|---|
| Energy Charge | 29.83 sen/kWh | 31.32 sen/kWh | 27.23 sen/kWh |
| Capacity Charge (Maximum Demand) | RM29.43/kW | RM30.19/kW | No MD charge |
| Network Charge (Maximum Demand) | RM59.84/kW | RM66.87/kW | No MD charge |
| Retail Charge | RM200/month | RM200/month | RM200/month |
High Voltage (Commercial – Tariff C3/C4, Industrial – Tariff E3)
| Component | General | ToU – Peak | ToU – Off-Peak |
|---|---|---|---|
| Energy Charge | 43.03 sen/kWh | 44.52 sen/kWh | 40.43 sen/kWh |
| Capacity Charge (Maximum Demand) | RM16.68/kW | RM21.76/kW | No MD charge |
| Network Charge (Maximum Demand) | RM14.53/kW | RM23.06/kW | No MD charge |
| Retail Charge | RM250/month | RM250/month | RM250/month |
For Medium and High Voltage ToU accounts, there’s no Maximum Demand charge during off-peak hours (all weekday hours outside 2pm-10pm, plus weekends). This is why factories and businesses that can shift heavy machinery use to off-peak hours – or pair solar with a battery to cover peak-hour demand – can see significant MD savings under ToU.
The MD charge is based on your highest recorded demand (kW) in any single 30-minute period during the billing month – not your total energy usage. This is separate from, and on top of, the energy charge (kWh), and for medium/high voltage industrial accounts it’s often the single largest line item on the bill. Solar with battery storage can specifically target MD reduction through “peak shaving” – discharging stored energy during your highest-demand periods.
If you run a shoplot, office, light factory or warehouse and want an exact tariff breakdown and how solar can reduce both MD and energy charges, read our Solar for SME Malaysia guide or contact us for a free bill audit.
AFA (Formerly ICPT) – Why Your Bill Fluctuates
Beyond the base rates above, your TNB bill is also subject to AFA (Automatic Fuel Adjustment) – a mechanism formerly known as ICPT. This is a two-way adjustment (rebate or surcharge) based on fluctuations in fuel costs and foreign exchange rates, reviewed monthly and published by TNB after confirmation from the Energy Commission at mytnb.com.my/tariff. No fixed cap on AFA has been published under RP4 – in practice, rates have already moved beyond +/-3 sen/kWh in several recent months, including +3.80 sen/kWh in August 2026 and +3.67 sen/kWh in September 2026, both confirmed by the Energy Commission. Read our full ICPT/AFA explanation and how solar can protect you from its swings.
Peak Hours (Time-of-Use) – An Option To Save More
Besides the standard tariff, TNB also offers an optional Time-of-Use (ToU) scheme that charges different rates by time – cheaper during off-peak hours, more expensive during peak hours (2pm-10pm on weekdays). This scheme can save you money if your usage pattern fits. Read the full peak hour schedule & ToU rates.

Frequently Asked Questions
What is the current TNB tariff rate (2026)?
For domestic users, approximately 44.43 sen/kWh (<=1,500 kWh/month) or 54.43 sen/kWh (>1,500 kWh), before AFA and the Energy Efficiency Incentive (EEI). Commercial/industrial tariffs vary by category and connection voltage.
Why did the TNB tariff increase in 2025?
Peninsular Malaysia’s base tariff rose 14.2% from 1 July 2025 under the new regulatory period (RP4) set by the Energy Commission, to cover infrastructure costs and the energy transition.
What’s the difference between the standard tariff and ToU?
The standard tariff charges the same rate all day. The optional ToU tariff charges a lower rate off-peak and a higher rate during peak hours (2pm-10pm weekdays) – it can save you money if your usage pattern fits.
Is the EEI rebate applied automatically?
Yes, the Energy Efficiency Incentive (EEI) is applied automatically based on your monthly usage – no separate application is needed.
What’s the difference between the Capacity Charge and Network Charge?
The Capacity Charge (4.55 sen/kWh) covers the generation capacity TNB must provide to meet national peak demand. The Network Charge (12.85 sen/kWh) covers transmission & distribution infrastructure costs (cables, substations). Both charges stay the same whether or not you register for ToU.
What if I use a prepaid meter?
The sen/kWh rate structure is the same for prepaid and postpaid meters – the main difference is just the payment method (top-up vs monthly bill). AFA and EEI still apply to both meter types.
How can I reduce my TNB bill?
Besides reducing usage, the most effective long-term approach is reducing your dependence on the TNB grid by installing solar panels. With tariffs continuing to rise, solar is an increasingly cost-effective long-term option. Read about solar installation costs for businesses or try our solar savings calculator.
Does TNB charge a minimum monthly fee?
There’s no separate flat minimum charge for domestic accounts beyond the RM10/month Retail Charge, which is automatically waived for usage of 600 kWh or less. Business accounts (C1-C2, E1-E3) may have minimum charge terms depending on your specific tariff category and connection – check your bill or contact TNB for your exact terms.
Is there a cap on how much AFA can change my bill?
No fixed cap has been published for AFA under RP4. In practice, monthly AFA rates have already moved beyond +/-3 sen/kWh in 2026 – for example +3.80 sen/kWh in August 2026 and +3.67 sen/kWh in September 2026, both confirmed by the Energy Commission. Check mytnb.com.my/tariff for the current month’s rate.
What is the 800 kWh electricity bill exemption I keep hearing about?
From 1 September to 31 December 2026, the Government temporarily raised the AFA/SST/Retail Charge exemption threshold from 600 kWh to 800 kWh per month, covering an estimated 90% of TNB’s domestic customers. This is a temporary measure – it’s not yet confirmed whether it will extend past 31 December 2026.
