NGCP energizes 6-Bn Mariveles-Hermosa transmission line

In its continued thrust to cater to the growing power needs of the Luzon grid, NGCP completes and successfully energizes its Mariveles-Hermosa 500kV Transmission Line on 30 March 2022.

The project involves the construction of a 49.2-kilometer transmission line connecting Mariveles to Hermosa, Bataan, and the construction of substations in Alas-Asin, Mariveles and Balsik, Hermosa. The transmission line will expand the existing capacity of the transmission facilities to accommodate more than 2,500MW of incoming generation from the Bataan Peninsula, including the GN Power Dinginin Coal-Fired Power Plant and the Mariveles Power Generation Corporation.

“NGCP’s mandate is to ensure that all capacities are capable of being delivered to load centers across the Philippines. It is important that we remain ahead of the curve by ensuring that lines are more than capable of delivering incoming power. NGCP is dedicated to doing its part in ensuring energy stability and resiliency, by making sure the power highways are always ready,” NGCP stated.

The new Hermosa (Balsik) Substation will house 2000 MegaVolt Ampere (MVA), the largest MVA capacity of any NGCP transformer bank to date, with the capability to expand to up to 4000MVA with the entry of bulk generation in the coming years. 

“The capacity of the new Balsik Substation will ensure that more power can be dispatched by the transmission system, and will greatly improve the overall grid reliability and stability of the 500kV network,” said NGCP.

The Mariveles-Hermosa 500kV Transmission Line project was certified as an Energy Project of National Significance by the Department of Energy on 16 January 2019, and has a cost of PhP 6 Billion as applied with the ERC.

“The completion of these high voltage facilities affirms NGCP’s commitment to its mandate of expanding the country’s transmission system. We continue to ask for the support of all our stakeholders to fast-track the completion of our other critical projects as we create a better and more resilient grid across the country,” said the company. 

Other critical projects in NGCP’s pipeline include the Hermosa-San Jose 500kV Transmission Backbone Project in Luzon, the Cebu-Negros-Panay and Cebu-Bohol Interconnection Projects, and the Mindanao-Visayas Interconnection Project, which aims to realize power sharing between the 3 main grids. 

NGCP is a Filipino-led, privately owned company in charge of operating, maintaining, and developing the country’s power grid, led by majority shareholders and Vice Chairman of the Board Henry Sy, Jr. and Co-Vice Chairman Robert Coyiuto, Jr. It is the sole operating asset of Synergy Grid and Development Philippines, Inc.##
