The National Grid Corporation of the Philippines (NGCP) said Thursday that it has completed key components of the Mindanao-Visayas Interconnection Project (MVIP), paving the way for the completion of the 52 billion peso interconnection project that will link the Visayas and Mindanao power grids.
NGCP has now moved significantly closer to interconnecting the Philippine power grid with the completion of several components of the Mindanao Visayas Interconnection Project (MVIP), notably the Santander and Dapitan cable terminals, the 350 kV (kV) submarine cable, and the 138 kV Lala Aurora transmission line. ‘, said the network operator.
NGCP completed the construction of cable terminals (CTS) in Santander, Cebu and Dapitan, Zamboanga del Norte, as well as the installation of two 92 km 350 kV high voltage direct current (HVDC) power cables and two 92 km fiber optic cables. . Site Acceptance Testing (SAT) was carried out on CTS Dapitan and Santander to ensure that these facilities comply with NGCP requirements.
Work on the submarine cable component began in November 2018 and was originally scheduled for completion in June 2021. However, restrictions on the entry of foreign specialists, work stoppages and workforce reductions caused by the Covid-19 pandemic have contributed to significant delays in the project. project execution. Damage to a submarine cable by a third-party vessel also delayed construction work, with repairs only completed in November last year.
NGCP also successfully connected the 138 kV Lala Aurora transmission line on February 19 last year. This MVIP component by itself will improve the reliability of electricity transmission services between Lanao del Norte and the provinces on the Zamboanga Peninsula.
The NGCP is pleased to announce that these important MVIP components are now complete and ready to be switched on. We hoped it would end on time, but factors beyond our control required an adjustment to our project schedule.
We are working twice as fast to complete the construction of overhead transmission line sections and bring the project to the commissioning stage to connect the networks of Luzon, the Visayas and Mindanao,” the company said in a statement.
Several other components are yet to be completed this October. This is the Dumanjug bus to the 138 kV Colon-Samboan transmission line in December 2022; 230 kV transmission line Dapitan-Lala, 230 kV transmission line Kauswagan-Lala and 230 kV transmission line Kolambugan-Lala in August 2022; and 350 kV Dumanjoug-Santander, 230 kV Magdugo-Dumanjoug and 230 kV Dumanjoug-Alegria.
The NGCP continues to seek support from local and national governments in order to succeed. Delays in issuing permits by local authorities, as well as right-of-way issues due to slow litigation and lack of support from landowners, continue to hamper our efforts.”
Through MVIP, Mindanao’s network will be connected to the Visayas network via an HVDC system with an initial capacity of 450 MW.
MVIP was certified as an Energy Project of National Importance in 2018 and was originally scheduled to be completed by December 2020, but has been delayed due to the Covid-19 pandemic and subsequent quarantine restrictions across the country. The NGCP has not announced a new MVIP termination goal.
The project covers 184 km of submarine cables and 526 km of overhead wires connecting Dapitan, Zamboanga del Norte, with Santander, Cebu.
