Ensuring a more stable power supply for Luzon consumers: PBBM inaugurates Mariveles-Hermosa-San Jose transmission line in Bataan



President Ferdinand R. Marcos Jr. on Friday led the inauguration of the Mariveles-Hermosa-San Jose (MHSJ) 500 Kilovolt (kV) transmission lines in Bataan.

“Once operational, this will strengthen power transmission services not only in the region but also in Metro Manila,” President Marcos said in his speech.

The transmission line will also connect with other projects in Bataan, such as the Battery Energy Storage System in Limay, which was inaugurated last year, and the Bataan-Cavite Interlink Bridge.

The MHSJ 500 Kilovolt (kV) has a total project cost of PhP20.94 billion, as approved by the Energy Regulatory Commission (ERC).

It was implemented by the National Grid Corporation of the Philippines (NGCP) from December 2017 to June 2024.

President Marcos said the project involves over 275.6 circuit kilometers of overhead lines supported by nearly 395 towers and two new substations.

He added the transmission line has a total transmission capacity of 8,000 megawatts (MW).

It will also serve as a vital corridor for the 5,080 MW and the additional 2,554 MW of committed power generation projects in Bataan and Zambales.

President Marcos extended his gratitude to the efforts of the NGCP and various government agencies in realizing the major transmission line project.

The President said the transmission project attests to the “transformative power” of collaboration between the public and private sectors to attain a stable, reliable, and resilient power supply.

“It will also help in the administration’s thrust to transition to renewable energy to mitigate the impact of geopolitical uncertainties and climate change,” President Marcos said.

President Marcos directed the Department of Energy (DOE) and the NGCP to complete the project on time as indicated in the Transmission Development Plan.

The President particularly mentioned the Batangas-Mindoro Interconnection Project and the Northern Luzon 230-kilovolt Loop.

“This way, we can meet our increasing energy demand, encourage technological advancements, and produce more employment opportunities for our people,” President Marcos said. PND
