TNB's fiscal year is from 1 September to 31 August.
Payment should be made within 30 days from the date the bill is issued.
No. All bills must be paid in full.
No. However, for certain cases, customers may refer the matter to a TNB Officer for approval.
Yes. This can be done during closure of accounts. However, if the deposit amount is insufficient, customers will have to pay the balance of the arrears.
If the customer’s average monthly electricity usage is more than the deposit paid, customer will be required to pay an additional deposit. For example:
Current deposit = RM100
Monthly average electricity usage = RM75
Deposit to be paid (RM75 x 2)= RM150
Additional deposit to be paid = RM50
The simplest way to reduce the electricity bill amount is to use electricity efficiently. However, this does not mean customers have to compromise on their standard of living or comfort level. Follow these quick and easy tips:-

It is a business as usual program that replaces aged meter which is beyond accuracy lifespan. There are two type of meters with different accuracy life span :-
The main objectives are:
The meter at customer premise is owned by TNB. However, customer is responsible to ensure meter is not disturbed /tampered.
Beginning 2004, TNB is installing electronic meters at customer’s premise in stages.
The meter measures your energy usage accurately and you will only be charged for the energy you actually use
The main possible reasons are the aged meter used earlier was not recording accurately due to :-
TNB replaces aged meters (more than accuracy life span) as it may no longer record accurate electricity consumptions. The replacement of aged meter is a utility prudent practice and is in accordance to the Electricity Supply Act 1990 (for accurate billing)
TNB has a customer database that records which meters have been in service beyond accuracy lifespan.
There will be a supply interruption at the customer’s premise for approximately 15 minutes to 1 hour.
Both electromechanical and electronic meters have the same accuracy class. Electronic meters can record with stringent accuracy.
The meter will be replaced by TNB appointed contractors who will be fully supervised by TNB staff. The contractors carry a TNB/NIOSH I.D. while the TNB staff wears TNB uniform and carries a TNB staff identification pass.
Replacement of the meter is conducted during normal working days and also on weekends (via appointment).
Identified customers will be notified through written notice at least 48 hours before the meter replacement is done.
Yes, TNB may enter customer’s property to replace the meter. This authority is granted under the Electricity Act 1990.
Please contact the Person in Charge stated in the letter to set an appointment.
Yes, consumption recorded from both aged and current meters will be calculated and included in customer’s electricity bill.
No.
No.
All meters go through stringent accuracy standards that comply with the Energy Commission’s Metering Guideline and International Standards
It is a guideline for electricity meters for approval, testing and initial verification requirements prior to the deployment for installation to the consumers. The guideline is governed by Energy Commission.
All meters are calibrated and certified to Metering Guideline under purview of Energy Commission.
All meters installed meet the Energy Commission Metering Guideline.
Meters are calibrated and accredited under Skim Akreditasi Makmal Malaysia (SAMM) based on MS ISO/IEC 17025:2005 issued by Standards Malaysia under purview of Ministry Of Science, Technology & Innovation (MOSTI).
The meters are also calibrated and comply to International Standards (MS IEC 62053-11, MS IEC 62053-21, MS IEC 62053-22, MS IEC 62053-23).
The meters also comply to International Standard OIML (e.g. Harmonics Test and Reliability Test).

Power quality is generally measured by the shape of the voltage waveforms supplied at the customer's meter. The voltage waveforms may reduce, increase, fluctuate or distort due to controllable or uncontrollable circumstances.
Any types of electrical equipments can be affected. Standard building systems such as lighting, HVAC and communications equipments are frequently affected. The most costly power quality problems often involve more sensitive high-tech equipments such as computer controlled equipment and data systems.
If you answer YES to any of these questions, you are likely to be experiencing a Power Quality problem:
The most common causes of Power Quality problems include lightning strikes, equipment failures, third party encroachment, weather conditions and operation of non-linear & fluctuating loads.
Some of the international standards that explain the power quality phenomenon are:

ICPT is a mechanism under the Incentive Based Regulation (IBR) framework which allows TNB as the utility to reflect changes (either increase or reduction) in fuel and other generation-related costs in the electricity tariff every six (6) months.
Suruhanjaya Tenaga as Malaysia’s energy regulator determines the calculation and methodology of the ICPT, subject to Government approval on a 6-monthly basis.
There are two ICPT key components:
The ICPT is calculated based on an estimated actual fuel cost and generation specific costs for a particular six (6) months period against the corresponding baseline costs in the Base Tariff.
The ICPT quantum for the period 1st January 2017 to 30th June 2017 is – 1.52 sen/kWh, i.e. a rebate of 1.52 sen/kWh.
Domestic customers with monthly consumption of 300kWh (RM77.00) and below were not affected in the previous tariff reviews i.e.:
The ICPT rate is fixed for all customers except for Domestic customers with monthly consumption of 300 kWh (RM 77.00) and below. However, the ICPT charge on your electricity bill may differ from your neighbour's as the ICPT charge depends on your energy consumption (kWh) in a month. Therefore this amount varies from one customer to another, and from month to month, depending on the energy consumption.
Time of Use (TOU) tariff scheme offers different tariff rates at different times of the day. For example, tariff rates during Off-Peak period will be lower than Peak period.
ETOU tariff scheme is introduced as an extension to the TOU tariff. Under this scheme, there will be three (3) time zones for Energy charge with Peak, Mid-Peak and Off-Peak rates.
On the other hand, Maximum Demand charge will have two (2) time zones with Peak and Mid-peak rates.
The scheme is also divided as follows:
Monday to Friday | 3 time zones with 3 energy rates for Energy charge: Peak, Mid-Peak and Off-Peak 2 time zones with 2 rates for Maximum Demand charge: Peak and Mid-Peak |
Weekends and Public Holiday | 1 time zone with 1 energy rate : Off-Peak rate only Maximum Demand Charge is waived during Saturday, Sunday, and Public Holidays |
Note: ETOU will only include these fixed Public Holidays: New Year (1 January), Labour Day (1 May), Merdeka Day (31 August), Malaysia Day (16 September) & Christmas (25 December)
TOU Tariff
TOU Time Zones are classified as follows:
ETOU Tariff
Enhanced Time of Use Time Zones | ||
Time Zone | Hours | |
Mid-Peak | 08:00 - 11:00 hours | |
Peak | 11:00 - 12:00 hours | |
Mid-Peak | 12:00 - 14:00 hours | |
Peak | 14:00 - 17:00 hours | |
Mid-Peak | 17:00 - 22:00 hours | |
Off-Peak | 22:00 - 08:00 hours |
The ETOU scheme will be offered as an option based on the schedule below:
Implementation of Enhanced Time of Use (ETOU) Schedule | ||
Date | Tariff Categories | |
Starting from 1 January 2016 |
Commercial customers at medium voltage (tariff C1 and C2) Industrial customers at medium and high voltages (tariff E1, E1s, E2, E2s, E3 and E3s) |
|
Starting from 1 January 2017 | Industrial customers at low voltage (tariff D and Ds) |
Note: However, low voltage Industrial customers may opt for the ETOU scheme starting from 1st January 2016, provided that they would upgrade to medium voltage tariff at their own cost.
TOU tariff scheme is offered to MV and HV customers under the following tariff category:
Demand for electricity will be different throughout the day therefore the electricity production cost will also change with time.
For example: During Peak hours, the demand for electricity is high and therefore higher cost of generation will be incurred to generate the electricity to supply to the customers. Thus, the Peak hour rate will be higher than Mid-Peak and Off-Peak rate.
No. The ETOU scheme is offered as an option to interested customers.
No. TOU customer must apply to TNB for the ETOU tariff scheme.
The objective of ETOU is to encourage Demand Side Management.
ETOU allows customers to manage their electric consumption efficiently by using less electricity during Peak hours.
ETOU is a self-regulating tool for customers to control their electricity usage and bill.
Customers will enjoy the reduction in monthly bill by shifting their consumption to Mid-Peak and Off-Peak hours, when the rates are lower
Customers must be committed to stay in the ETOU scheme for a minimum of 6 months.
After 6 months, customers have the option to cancel their ETOU tariff scheme and revert to the previous tariff scheme; and all cost associated will be borne by them.
No. SIT customers will be offered the same ETOU rates offered to non-SIT customers.
No. Customer must choose either one of the applicable tariff scheme for their respective account.
No. ETOU will be offered as an option for eligible customers.
Customers must choose the appropriate tariff scheme that best suits their energy consumption.
Customers who wish to enroll for ETOU scheme can submit formal application stating TNB Account to respective TNB Kedai Tenaga.
MD is measured in Kilowatt (kW). It is the highest level of electrical demand monitored in a particular period usually for a month period. Maximum Demand for any month shall be deemed to be twice the largest number of kilowatt-hours (kWh) supplied during any consecutive thirty minutes in that month.
MD is the peak load imposed by the customer to TNB system at any point of time. TNB need to cater for this peak load whenever required by the customer. Since electricity cannot be stored there must be sufficient available generation, transmission and distribution capacity to meet the highest demand. MD tariffs are structured to reflect the time of day it is used. For these reasons most tariffs for larger users are designed to encourage customers to control their electricity demand at daytime peaks. For example, lower night rate electricity encourages the transfer of daytime usage to the night period. The MD charge is being practiced by almost all utilities in the world.
TNB imposed MD charge to its large customers, those at medium and high voltage level. The MD charge component is necessary to take into account the peak load imposed to the system by these customers. Waiving this MD charge will result in very high energy rate and does not encourage customers to use electricity efficiently. However, those small customers at low voltage level are only imposed energy charge as their peak load requirement is low.
Few activities could be carried out by customers that assist in reducing MD charges such as:
The ICPT is calculated based on an estimated actual fuel cost and generation specific costs for a particular six (6) months period against the corresponding baseline costs in the Base Tariff.
The ICPT quantum for the period 1st January 2017 to 30th June 2017 is – 1.52 sen/kWh, i.e. a rebate of 1.52 sen/kWh.
Domestic customers with monthly consumption of 300kWh (RM77.00) and below were not affected in the previous tariff reviews i.e.:
The ICPT rate is fixed for all customers except for Domestic customers with monthly consumption of 300 kWh (RM 77.00) and below. However, the ICPT charge on your electricity bill may differ from your neighbour's as the ICPT charge depends on your energy consumption (kWh) in a month. Therefore this amount varies from one customer to another, and from month to month, depending on the energy consumption.
Power Factor is an index used to compute the efficiency level of electricity usage. The index is measured from 0 to 1. A higher index shows efficient usage of electricity and vice versa. Low power factor shortens the lifespan of electrical appliances and causes power system losses to TNB. To understand power factor, we will start with the definition of some basic terms:-
KW | Working Power (also called Actual Power, Active Power or Real Power). It is the power that powers equipment and performs useful work. |
KVAR | Reactive Power. It is the power which magnetic equipment such as transformers, motors and relays need to produce the magnetizing flux. |
KVA | Apparent Power. It is the vectorial summation of KVAR and KW. |
Let’s look at a simple analogy in order to better understand these terms. Let’s say you are at a park and it is a hot day. You order a glass of a carbonated drink. The thirst-quenching portion of the drink is represented by KW. Unfortunately, along with your drink comes a little bit of foam. The foam does not quench your thirst. This foam is represented by KVAR. The total content of your glass, KVA, is this summation of KW (the carbonated drink) and KVAR (the foam).
Power Factor is the ratio of Working Power to Apparent Power. Power Factor = KW / KVA |
Looking at our carbonated drink analogy, power factor is the ratio of carbonated drink (KW) to the carbonated drink plus foam (KVA). Power Factor = KW / (KW + KVAR) = Carbonated drink / (Carbonated drink + foam)
Thus, for a given KVA:- i. The more foam you have, the lower your power factor. ii. The less foam you have, the higher your power factor. |
For efficient usage of electricity, power factor must approach 1.0. A Power factor that is less than 0.85 shows inefficient use of electricity.
In our carbonated drink analogy, low power factor resulted when the amount foam is was large. Low power factor is caused by inductive loads, which are sources of reactive power. Examples of inductive loads are:-
Inductive loads constitute a major portion of power consumed by commercial and industrial sectors.
Customers are advised to follow these steps:
Benefit 1: Reducing KW billing demand
Low Power Factor requires high reactive power (KVAR) and apparent power (KVA), which is the power that TNB supplies. Therefore, a facility’s low power factor forces TNB to increase its generation and transmission capacity in order to handle this extra demand. By increasing the power factor, customers use less KVAR. This results in less KW, which equates to RM savings for TNB.
Benefit 2: Eliminating power factor surcharge
Utility companies all around the world charge customers an additional surcharge when their power factor is less than 0.95. In fact, some utilities are not obliged to deliver electricity to their customers at any time the customer’s power factor falls below 0.85. Thus, customer can avoid this additional surcharge by increasing power factor. In Malaysia, TNB is allowed through the Malaysian Grid Code and the Malaysian Electricity Distribution Code, to impose a surcharge to the customer if the power factor is < 0.85 for customers receiving less than 132kV.
Benefit 3: Increased system capacity and reduced system losses in your electrical system
Low power factor causes power system losses in the customer’s electrical system. By improving power factor, these losses can be reduced. With the current rise in the cost of energy, increased facility efficiency is important. Moreover, with lower system losses, customers are able to add additional load in their electrical system.
Benefit 4: Increased voltage level in your electrical system, resulting in more efficient motors
As power losses increase, customer may experience a voltage drop. Excessive voltage drops can cause overheating and premature failure of motors and other inductive equipment. Therefore, by raising the power factor, customers can minimise these voltage drops along feeder cables and avoid related problems. Motors will run more efficiently, with a slight increase in capacity and starting torque.
