Connection to NGCP’s Vis-Min network nears completion


The 52 billion peso Mindanao-Visayas Interconnection Project (MVIP) is “on track” to be completed before the end of the year after the integral components of the project are in place, the National Grid Corp said. . of the Philippines (NGCP).

The network operator has so far completed the terminal stations of the Santander and Dapitan cable, the 350 kilovolt submarine cable and the 138 kV Lala-Aurora transmission line.

It also carried out the construction of the Cable Terminal Stations (CTS) in Santander, Cebu and Dapitan, Zamboanga del Norte, as well as the installation of two 92 kilometer high voltage direct current (HVDC) power cables and two of 92 kilometers Fiber optic cables.

“Site acceptance testing has been performed at Dapitan and Santander CTS to ensure said facilities meet NGCP requirements,” the company said in a statement.

The MVIP will link the power grids of Visayas and Mindanao, creating a single national grid through an HVDC system with an initial capacity of 450 megawatts.

Its completion was originally scheduled for June 2021 but the coronavirus pandemic, which has restricted the entry of foreign experts, suspended work and reduced the workforce, has caused significant delays, forcing the NGCP to adjust the schedule. of the project.

Damage to the No. 1 submarine cable caused by a third-party vessel has also delayed construction activities, with repairs not completed until November last year.


The NGCP said the MVIP had also encountered setbacks due to delays in local government permits and right-of-way issues “due to slow legal processes and unsupportive landowners”.

“We hoped this would be completed on time, but factors beyond our control necessitated an adjustment to our project schedule. We are working double time to complete the overhead transmission line portions and advance the project to its commissioning stage to connect the networks in Luzon, Visayas and Mindanao,” NGCP said.

“The NGCP continues to appeal for the support of local and national government to bring this to fruition,” he added.

Going forward, the company will work on several other components of the project, such as the 350 kV Dapitan-Lala transmission line, the 230 kV Kauswagan-Lala transmission line and the 20 kV Kolambugan-Lala transmission line in august.

Also lined up are the Dumanjug-Santander 350 kV transmission line, the Magdugo-Dumanjug 230 kV transmission line and the Dumanjug-Alegria 20 kV transmission line in October, as well as the Dumanjug Bus-in to Colon-Samboan 138 transmission line. kV. in December.
