NGCP recently completed the San Jose-Angat 115 kiloVolt (kV) Transmission Line Upgrading project, further securing the reliability of power transmission services for the Luzon grid.

The old San Jose-Angat Lines 1 and 2 were built in 1967 to connect the Angat Hydroelectric Power Plant to the Luzon grid, while another circuits composed of wooden poles, was built in 1960. The upgrading of this line is critical to the overall reliability of transmission services for Luzon, since the aged line will not be able to handle the full capacity dispatch of the 246 megawatt (MW) power plant.

A new third circuit spanning 18 kilometers was successfully upgraded on May 20, 2022. A fourth circuit of the same length was completed on April 13, 2022. The 300 megavolt-amperes (MVA) capacity per circuit of the upgraded line will now provide N-1 contingency, which is the ability of the grid to withstand a major system disturbance with minimal or no impact to the system.

The associated 115 kV Substation was also upgraded with new power circuit breakers to accommodate the capacity of the two new lines connected to the substation.

“The completion of this project affirms our continuing commitment to upgrade the transmission network of the country. We are happy that the project is now energized to keep the grid running at optimum condition as we create solutions which will help our economy grow,” said NGCP.

The Energy Regulatory Commission-approved the P307-million project was certified by the Energy Investment Coordinating Council of the Department of Energy as an Energy Project of National Significance on  January 16, 2019.

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.
