What Is Tenaga Nasional Berhad (TNB)?
Tenaga Nasional Berhad (TNB) is the largest electricity utility company in Malaysia. It manages power generation, transmission, and distribution nationwide, serving residential, commercial, and industrial customers. As the operator of the national grid, TNB plays a crucial role in ensuring reliable electricity supply and supporting Malaysia’s energy infrastructure.
Through the myTNB portal and mobile app, customers can pay bills, monitor usage, and manage accounts digitally. For assistance, TNB provides customer support via Careline at 1-300-88-5454 (weekdays 8:00 AM to 7:00 PM, weekends 8:00 AM to 5:00 PM). For power outages, customers can call the 24-hour hotline at 15454.
How Does TNB Structure Its Electricity Tariffs?
TNB uses a tiered pricing system where electricity charges rise with higher consumption. Bills include charges based on kWh usage and adjustments such as the Imbalance Cost Pass-Through (ICPT), which reflects fuel and generation cost fluctuations. Rates are higher during peak hours (8 a.m. to 10 p.m.), encouraging users to shift consumption to off-peak times.
Customers may estimate their bills using the TNB Bill Calculator available on the official website. The July 1, 2025 tariff update introduced clearer billing components, which are also reflected in the latest myTNB app update.
What Payment Methods Does TNB Accept?
TNB accepts a variety of payment methods including myTNB, e-Wallets, JomPAY, online banking, AutoPay, phone banking, and over-the-counter payments. These methods ensure flexibility and convenience for customers. The myTNB app integrates most options, allowing for quick and seamless transactions.
AutoPay enables automatic deductions to avoid missed payments. Customers preferring physical transactions can pay over the counter at Kedai Tenaga outlets, which can be located through the myTNB app.
How Does Solar Energy Reduce TNB Bills?
Solar energy reduces TNB bills through the Net Energy Metering (NEM) program. Customers generate electricity using solar panels, and any excess is exported to the grid. Exported energy appears as Baki NEM credits on bills and offsets charges. Unused credits reset every December 31. Depending on system size and usage, savings can reach 50–90%.
Solar adoption supports sustainability and provides long-term financial benefits. Rent-to-Own (RTO) solar plans from providers such as GetSolar allow customers to install solar panels with zero upfront cost and low monthly payments.
What Digital Services Does TNB Provide?
TNB’s digital services are available through the myTNB portal and mobile app. These platforms allow account registration, bill checking, payments, consumption tracking, and multiple account management. Customers can view billing history, receive notifications, and locate Kedai Tenaga outlets through the app.
The June 30, 2025 update enhanced user experience by aligning the app with new tariff structures. Despite occasional login and update issues, myTNB remains the primary tool for digital electricity service management in Malaysia.
How Does TNB Support Customer Service?
TNB offers customer support via Careline and online platforms. Customers can reach Careline at 1-300-88-5454 during working hours or call 15454 at any time to report outages. Support is also available through the myTNB portal and the official Facebook page @TNBCareline.
The self-service portal allows existing myTNB users to access services without re-registration. For managing 20 or more accounts, customers must contact Careline directly.
How Can Customers Manage Multiple TNB Accounts?
Customers can manage multiple TNB accounts through the myTNB portal or mobile app. This feature allows centralized monitoring of energy use, bill payments, and notifications. Landlords, businesses, or customers with multiple properties benefit from streamlined management across accounts.
For bulk management of 20 or more accounts, customers should contact TNB Careline for dedicated support.
What Are Common Issues with the myTNB App?
Customers report issues such as login difficulties, delays in consumption updates, and limited real-time tracking. Despite these challenges, TNB has addressed many concerns through updates, including the June 30, 2025 release that improved billing clarity.
For unresolved problems, customers are encouraged to contact TNB Careline for troubleshooting assistance.
How Does TNB Ensure Energy Efficiency?
TNB promotes energy efficiency by encouraging the use of energy-efficient appliances and shifting usage to off-peak hours. The myTNB app allows customers to track consumption and adopt better energy-saving habits.
The NEM solar program further supports efficiency by enabling households and businesses to generate their own electricity and reduce dependence on the grid.
What Is the Imbalance Cost Pass-Through (ICPT) Charge?
The ICPT charge is an adjustment on TNB bills that reflects changes in fuel and generation costs. It ensures that fluctuations in production costs are passed transparently to consumers, while maintaining reliable service. This charge is reviewed periodically and approved by regulators.
Bills display the ICPT separately from base electricity charges, giving customers a clear understanding of total costs.
How Does TNB Handle Power Outages?
TNB manages outages through its 24-hour hotline at 15454. Customers are encouraged to report outages immediately, enabling repair teams to restore supply quickly. Safety tips and outage information are also available on TNB’s website.
Rapid response and clear communication strengthen customer trust and ensure reliability during service disruptions.
What Are the Benefits of the myTNB App?
The myTNB app provides benefits such as bill checking, consumption tracking, payment integration, notifications, multiple account management, and location of Kedai Tenaga outlets. These features provide convenience and control over electricity management.
The 2025 update added support for the restructured tariff system, giving customers clearer bill details and a better overview of usage.
How Can Customers Register for myTNB Services?
Customers can register for myTNB services through the portal or mobile app. Registration requires providing account details to set up digital access for bills, payments, and service management. Existing myTNB users do not need to re-register for the self-service portal.
