With merely three weeks before the December 24 deadline for the restoration of power in the Visayas region, the country’s power grid operator has fast-tracked the energization of transmission lines that were hard hit by Super Typhoon Yolanda.
Around 72 percent of the whole Visayas load has been restored because of the energization of transmission facilities.
As of November 28, the National Grid Corp. of the Philippines (NGCP) energized two 230-kilovolt (kV) lines and three 138-kV lines on Leyte island, two 138-kV lines on Samar island and one 138-kV line in Bohol. The grid operator also energized 14 69-kV lines on Leyte, Samar and Panay islands.
These lines, which represent five of the eight priority transmission grid backbones for restoration, transmit electricity to substations that will bring back power to Leyte, Bohol and Samar.
The latest energized transmission backbones of NGCP are the Ormoc-Babatngon 138-kV line in Leyte, Babatngon-Paranas 138-kV line traversing Samar and Leyte, Paranas-Calbayog 138-kV line in Samar and the Dingle-Panit-an 138-kV line in Capiz.
“These restoration updates are good news to the Visayas, However, NGCP would like to clarify that, though our transmission facilities are restored, some municipalities may still experience rotational brownouts because of supply deficiency due to isolation of several power plants affected by Typhoon Yolanda,” Cynthia Alabanza, NGCP spokesperson, said.
To date, 13 electric cooperatives already have access to power. These coops are the Iloilo Electric Cooperative I, II and III, Antique Electric Cooperative, Capiz Electric Cooperative, Leyte Electric Cooperative II, IV and V, Southern Leyte Electric Cooperative, Samar Electric Cooperative I and II, Eastern Samar Electric Cooperative and Northern Samar Electric Cooperative.
Based on NGCP’s assessment, Yolanda damaged more than 2,000 transmission structures of 34 transmission lines and affected 23 substations in the Visayas.
