Philippine NGCP concludes Mindanao 230 kV backbone project [free access]

December 17, 2020

The concessionaire for the Philippine transmission network, National Grid Corporation of Philippines (NGCP), recently energised the 230 kV Toril─Bunawan transmission line, which was the last component of the Mindanao 230 kV backbone project.


The now completed PHP7.09 billion project involved the upgradation of the Malita, Matanao, Toril, Bunawan, Balo-i, Villanueva and Maramag substations. The project also entailed construction of the 230 kV Toril─Bunawan and Matanao─Toril transmission lines and the upgrade of the Balo-i─Villanueva─Maramag─Bunawan line from 138 kV to 230 kV.


As one of the integral projects being implemented by NGCP, the Mindanao backbone will connect bulk generation power plants and ensure stable and continuous power from Lanao del Norte, passing through Misamis Oriental and Bukidnon, all the way to Davao Del Sur and Davao Occidental. The completion of this project is vital to the Mindanao–Visayas Interconnection Project (MVIP)—which aims to complete the link between the nation’s power grids—as the former will create a transmission highway to ensure the full capacity utilisation of the latter by both the Visayas and Mindanao regions.
