Smart Meters and their Benefits

Smart Meters are a new way for Malaysians to get their meter readings for a better energy experience.


Smart Meters are a new way for Malaysians to get their meter readings for a better energy experience.

A Smart Meter is a device that records your electricity usage and communicates this information automatically to TNB for efficient monitoring and billing. They read your daily energy usage and provide more accurate bills for a smarter, greener and more energy efficient future.

Smart Meters can help you keep an eye on how much energy you are using at your premises. By using our interactive myTNB app and/ or the myTNB Portal, you can track how much energy you are using and view how much your electricity bill may reach to make smarter, energy-saving decisions.


  1. Smarter Control
    • Smart Meters share information with your myTNB App and the Portal so you can track and monitor your energy usage to budget your electricity consumption and help the environment.
  2. Smarter Information
    • View half-hourly energy usage updates via the myTNB Portal
    • Receive notifications via the myTNB app when you set your Energy Budget.
  3. Smarter Payments via the myTNB App/Portal
    • Smart Meters continuously read your energy usage to give an accurate bill. You can pay your Smart Meter bill anytime, anywhere via the myTNB app.


Smart Meters can help you better budget your electricity consumption and in turn, save the environment for a smarter, greener Malaysia. Here’s how:

Grid of The Future

Smart Meters form an integral part of the creation of a smart grid, which uses digital technology to manage and supply electricity where it’s needed. Our energy networks will run in a completely new way, helping TNB to improve your customer experience and our services while allowing us to gain better control of the grid and enhance the efficient use of energy.

A Greener Malaysia

You can make an impact towards a greener Malaysia by monitoring your energy usage frequently, in greater detail and by making smarter, energy-saving decisions like turning off appliances, changing to more efficient lighting, adjusting thermostats, buying energy efficient appliances, etc. By conserving energy, we use and produce less electricity, resulting in reduced emissions due to decreased power generation and potentially better air quality for Malaysia.


Are Smart Meters Harmful?

In TNB’s collaboration with Wireless Communication Centre (WCC) Universiti Teknologi Malaysia (UTM), studies conducted shows that Radio Frequency Electromagnetic Frequency (RF-EMF) emission by the Smart Meter is proven to be safe. The RF-EMF waves emitted by the Smart Meter is considered as Non-Ionizing and will not disrupt the structure of biological material. It lacks the energy to break the chemical bonds within molecules, thus it CANNOT cause ionization to the human body.

Based on 25000 published research articles regarding RF-EMF emission, the World Health Organization (WHO) even stated that “Current evidence does not confirm existence of any health consequences from exposure to the field low level electromagnets”.

Rest assured that all TNB issued radio frequency devices, including Smart Meters, are tested and certified by SIRIM for compliance and safety in Malaysia and comply with the safety regulations set and regulated by the Malaysian Communications and Multimedia Commission (MCMC).

Can Smart Meters Spy on Me?

Like your traditional meters, Smart Meters do not have the capacity to see, hear and/or spy on you. The Smart Meter simply measures the amount of energy you use in half-hourly intervals and records the meter readings with TNB remotely. You can view this information via the myTNB Portal to help you better track and manage your energy usage.
