Iconic TNB Tower Project To Strengthen Penang’s Electricity Supply

Tenaga Nasional Berhad (TNB) today launched the Penang Electricity Supply Strengthening Project through the fourth transmission line, which is capable of supplying up to 2,000 megawatts (MW) directly from the National Grid in the mainland Peninsula to the Penang Island.

The transmission system through the 275kV overhead transmission line measuring 8.5 kilometers, will be stretched parallel to Penang’s first bridge using 31 single towers (monopoles), connecting the Main Input Substation (PMU) of the Perai Power Station (SJ) to The Light PMU, which will be built in the Northeast District near Batu Uban Army Camp.

Penang Chief Minister Chow Kon Yeow said that the project is something that the people of Penang have been waiting for as a catalyst for the development of the state, in line with the Penang2030 Vision.

“We can plan and strategise for giant projects even, but it cannot be achieved without sufficient and stable energy supply. This is the role played by TNB with the implementation of the project today,” he said while launching the project.

The three existing electricity supply transmissions to the island are through the 132kV submarine cable from SJ Prai – SJ Gelugor which began work in 1978; 132kV cable under the bridge (1989) and 275kV submarine cable from PMU Juru – PMU Bayan Lepas (1995), alongside SJ Gelugor.

The Minister of Energy and Natural Resources, Datuk Seri Takiyuddin Hassan said, it is appropriate to implement this overhead line project, which has a much higher electricity transmission capacity compared to the method of under-bridge cables and submarine cables. It is capable of sending 2,000MW of supply from SJ Perai to the PMU depending on the load demand in the island area.

He added the project worth over RM500 million will ensure the people and investors in Penang continue to receive stable and reliable electricity supply, as demand is expected to increase in line with post-pandemic economic recovery.

“Maintaining the stability of this supply will be a catalyst for economic growth in various fields including industry, infrastructure development, transport and tourism. In fact, this transmission line itself has become a tourist attraction with six of its 31 towers having an iconic betel nut-shaped design,” he said.
