Would TNB’s New Electricity Bill Format Enhance Transparency For Customers?

Starting today, Tenaga Nasional Berhad (TNB) customers can monitor their electricity usage more closely with the introduction of a new, more detailed bill format and a revised electricity tariff structure. This change, announced by the Energy Commission, follows the government’s approval under the Incentive-Based Regulation (IBR) mechanism, as outlined in Section 26 of the Electricity Supply Act 1990.

Detailed Breakdown of Electricity Charges

The main reason for this change is to improve transparency. According to the official myTNB website, your bill will now clearly separate charges into several key components so you can see where your money goes. The main categories are the Generation Charge, the Network Charge, and the Retail Charge. The Generation Charge covers costs related to fuel, power plant capacity, and adjustments due to global fuel price fluctuations. The Network Charge covers operational expenses for maintaining the transmission and distribution systems that deliver electricity, and the Retail Charge relates to services such as customer support and billing. By itemising these charges, the new format gives you a clearer understanding of how your electricity costs are calculated, empowering you to make more informed decisions about your energy use.

The New 2-Block Tariff and How Your Bill is Calculated

The new tariff simplifies the domestic billing structure by reducing the previous five-block system to just two blocks, making it easier to estimate your expenses. The structure features a lower rate for electricity consumption up to 1,500 kilowatt-hours (kWh) per month, and a higher rate for any usage above that threshold. For example, a household that uses 1,700 kWh in a month would find its bill calculated in two parts. The Generation Charge for the first 1,500 kWh would be calculated at the lower rate, while the remaining 200 kWh would be calculated at the higher rate.

Incentives for Energy Efficiency

The new structure includes powerful incentives to reward energy-saving habits. A new monthly Retail Charge of RM10 is introduced; however, this charge will be waived automatically for customers who keep their monthly electricity usage at 600 kWh or below. To further support responsible energy use, TNB also continues to offer an Energy Efficiency Incentive for domestic customers whose monthly electricity consumption is up to 1,000 kWh. This programme provides additional assistance to households that consistently keep their usage low.

Time of Use (ToU) Tariff Option for Homes

For the first time, TNB’s Time of Use (ToU) tariff is now available to residential customers who wish to manage their electricity usage based on peak and off-peak pricing. This can be especially beneficial for those who can shift heavy appliance use to off-peak hours. The higher-priced peak period runs from 2:00 PM to 10:00 PM on weekdays, while all other times, including the entire weekend, are considered lower-priced off-peak periods. Participation is voluntary and requires a compatible meter, such as a Smart Meter. Customers interested in the Domestic ToU scheme can apply through the myTNB app, website, or any Kedai Tenaga branch.

Billing, Verification, and Support

During this month, you will receive a transitional bill reflecting two sets of usage charges, one calculated with the old tariff up to June 30th and one with the new tariff from July 1st. This bill will be available within 24 hours on the myTNB app and portal. Beginning in August 2025, all customers will receive bills in the complete new format. To ensure accuracy, TNB will provide customers with a meter reader verification slip as proof that a reading has been taken. To support you during this transition, TNB has also introduced an online Electricity Bill Calculator, which allows you to estimate your bills based on your expected usage and the new tariff rates.
