The National Grid Corp. of the Philippines said it is working to repair one of its 138kV high voltage submarine cables damaged during the dredging and re-channeling activities of the Department of Public Works and Highways at Bio-os River in Brgy. Jagna, Amlan town in Negros Oriental last month.
The cable, that interconnects Negros and Cebu, has two circuits of 138kV submarine cable with 90-megawatt capacity each, NGCP Visayas corporate communications and public affairs officer, Michelle Visera, said in an advisory furnished the DAILY STAR yesterday.
“Because of the damage to one of the two circuits, transmission capacity is currently limited to 90MW between the two islands,” Visera said, adding that the NGCP’s System Integrity Protection Scheme was automatically activated after the incident to isolate the affected circuit and prevent overloading of the remaining cable.
Initial reports received by the NGCP show that a deviation on the agreed work site by the DPWH was a contributing factor to the incident.
NGCP has requested the local government of Amlan and the DPWH to temporarily stop their operations, and immediately implement measures to contain the oil spill, Visera said.
It is unfortunate that this happened at such a crucial time when electricity is critical to Covid-19 response efforts. “NGCP assures its stakeholders that all hands are on deck to restore the affected facility and mitigate the impacts of the oil spill and scattered cable debris,” she added.
The extent of the damage was fully assessed on June 23 and 24, and coordination is ongoing with partner foreign technical experts for the commencement of actual repair activities.
NGCP is a Filipino-led, privately owned company in charge of operating, maintaining, and developing the country’s electricity transmission grid, led by majority shareholders vice chairman of the Board Henry Sy Jr. and co-vice chairman Robert Coyiuto Jr.*
