‘Foreign objects’ caused the blackouts experienced by Puerto Princesa since August 20, the chair of the board of directors of the Palawan Electric Cooperative (PALECO) said Wednesday.
Jeffrey Tan Endriga, chairman of the Paleco board said the blackouts are due to several causes, one of which was a problem in the National Power Corporation (NPC) “tie-line” that connects to their substation.
Endriga told Palawan News that the power flow was affected when the NPC tie-line came in contact with a “foreign object.”
This foreign object can be a tree limb, a bird, or any that can cause transformers, fuses, or any other electrical equipment to momentarily fail or shut down completely, he pointed out.
“Maraming kadahilanan upang magkaroon ng power interruption. Yong nangyaring total blackout ay sanhi ng problema ng ating tie-line na pagmamay-ari ng NPC. Kung baga sa isang tulay, kung hindi makalusot ang sasakyan, walang makakalusot na kuryente. Parang ito na ang pinaka-sample nito,” he said.
Endriga said distribution lines are divided by “sectors” and those that are experiencing disturbances will cause power outages to consumer homes in communities they cover.
He added that if a certain line is not affected, there will be no power outage in the area it covers.
“Naka-sectoral ang ating mga linya kaya kung saan ‘yong may problema, doon lang magkakaroon ng brownout, pero not the whole system. Yong pangyayari kasi doon sa total blackout mismong transmission line ang nagkaroon ng problema,” he said.
He said it is understandable that Paleco gets blamed for the power problems that are happening, but consumers should also understand that they are doing their best to provide better service.
“Hindi tayo magsasawa na magpaliwanag at magbigay ng impormasyon para sa ating mga member-consumer-owner dahil obligasyon po natin ito sa kanila,” he added.
On the power interruptions that occurred on August 19 from around 2:30 a.m. to 4:00 a.m., Endriga emphasized they were not total blackouts, only sectional.
Power outages may also be caused by weather disturbances like high winds and lightning strikes.
“Kapag panahon ng tag-ulan, kasi nga naka-pair wire tayo, konting sagi lang po ng sanga ng puno o kung ano man yong dumapo ay nag-tri-trigger na ito ng interruption,” Endriga said.
He said they already have proposed solutions to the problem, but these still await the approval of the Energy Regulation Commission (ERC).
