A line fault that occurred in the 69kv transmission line being maintained by the National Power Corporation (NPC) between Aborlan and Narra was what caused the total blackout that started around 5 a.m. Tuesday.

Palawan Electric Cooperative (PALECO) board chair Jeffrey Tan-Endriga said DMCI Power Corporation Aborlan will not be able to supply electricity to Narra.

Endriga said Palawan Power Generation Inc. (PPGI) is supposed to supply power to Narra and Sofronio Española, but because its capacity is only limited to 4 megawatts, there is a possibility that the latter will not have electricity until the NPC is able to fix the 69kv transmission line.

“Ang transmission line na may fault is between Aborlan and Narra. Hindi po makakapag-supply sa Narra ang DMCI Aborlan at tanging PPGI Narra lang ang magsusupply sa Narra at [Sofronio] Española. Ngunit dahil limitado lang sa 4MW ang capacity ng PPGI Narra, may posibilidad na hindi mapapailawan ang [Sofronio] Española hangga’t hindi naibabalik ang NPC transmission line,” he said.

Endriga said the NPC crew will come from Puerto Princesa to do line patrol, but as of this writing, it has not sent word about its status. The concerned transmission line is currently isolated.

He also said that Narra and some parts of Brooke’s Point to Sofronio Española will switch to island mode because of the isolated line.

“Magsasagawa naman ng pag island mode ang Narra at bahagi ng Brooke’s Point hanggang So. Española dahil sa naka isolate na linya,” he said.
