THE National Grid Corp. of the Philippines (NGCP) is undertaking over P132 billion worth of major interconnection projects to realize its vision of a unified Philippine grid.
The largest project in the pipeline is the P51.7-billion Mindanao-Visayas Interconnection Project (MVIP), considered as the largest energy infrastructure in the country, that is slated for completion in December this year.
The MVIP will complete the link between the nation’s power grids, allowing electricity between the major islands to be shared and ensuring the reliability and stability of the grid.
Another is the P47.8-billion Stages 2 and 3 of the Cebu-Negros-Panay Interconnection Project which will establish a 230-kilovolt (kV) backbone to accommodate the transmission of excess power from Panay and Negros towards the rest of the Visayas.
The grid operator also started pre-construction activities for the P8.5-billion Nabas-Caticlan-Boracay transmission line project as well as the pre-construction stage of the P2.4 billion Panay-Guimaras 138kV transmission line.
These two projects shall address the growing demand in Boracay Island and provide additional capacity to support the ongoing developments.
The NGCP is also constructing the P1.9-billion Cebu-Lapu Lapu 230kV transmission line project, with survey and right-of-way activities ongoing, to maintain the continuous transmission of power towards the major load centers in Mandaue and Mactan during N-1 condition.
Also, the P19.8-billion Cebu-Bohol 230kV Interconnection Project will address overloading issues and enable sharing of power between the two islands, especially the growing demand in Bohol and eventually form part of the Leyte-Bohol 230kV loop system upon completion.
Other future interconnection projects include the Batangas-Mindoro Interconnection Project, Laray-Cordova 230kV Transmission Line project, Bataan-Cavite Interconnection Project, Bataan-Pasay Interconnection Project, and the Palawan-Mindoro Interconnection Project.
“The only way to forward this vision of a fully interconnected and integrated transmission system is to keep investing in the transmission grid. These projects will greatly benefit the country, energizing the entire archipelago even up to the farthest islands,” NGCP said in a statement on Tuesday.
“This will also prepare the entire Philippine grid for the integration to the proposed Asean Power Grid, promoting power sharing and optimization of generation capacity within the region,” it added.
So far, the company completed the P6.1-billion Cebu-Negros-Panay Stage 1 submarine cable component which increases the transfer capacity of the existing corridor.
The second phase of this project is an additional submarine cable for N-1 contingency which will enable the transmission grid to withstand a major system disturbance with minimal disruption to the system between Negros and Panay islands.
The NGCP — the consortium of Henry Sy Jr.’s Monte Oro Grid Resources Corp., Robert Coyiuto Jr.’s Calaca High Power Corp. and State Grid Corp. of China — is in charge of operating, maintaining, and developing the country’s power grid.
