supply, crucial for maintaining the socio-economic momentum of the nation. Serving over 10.16 million customers across Peninsular Malaysia, Malaysia’s grid is also connected to Thailand’s transmission system operated by The Electricity Generating Authority of Thailand (EGAT) through a 300kV high voltage direct current interconnection with a transmission capacity of 300MW and a 132kV high voltage alternating current system with a maximum transmission capacity of 80MW. T o the South, we have an interconnection to the Singapore’s National Grid via two 230kV submarine cables with a firm capacity of 1,100MW. The management of this extensive network falls under two of our core divisions’ purview: Grid and Distribution Network (DN). Grid plans and develops the transmission network at 132kV and above, while DN performs a similar role for the distribution networkat 33kV and below. Beyond the peninsular, the state of Sabah and the Federal Territory of Labuan are catered to by the Sabah Electricity Sdn. Bhd. (SESB). This segment of the grid connects around 690,000 customers, extending TNB’s reach and reinforcing our dedication to powering every corner of Malaysia. DEVELOP ENERGY TRANSITION NETWORK OVERVIEW The Malaysian electric grid acts as the backbone supporting the dynamic landscape of Malaysia’s energy sector. As the foundation upon which the energy transition infrastructure is built, our grid embodies the essence of resilience, innovation, and adaptability. In an era where the demand for electricity is not only increasing but also becoming more complex, TNB has been at the forefront of developing a robust grid system that caters to both today’s needs and tomorrow’s aspirations.
