Electricity was cut in Northern and Eastern Samar on Saturday after winds whipped up by Typhoon Ruby downed several power lines.
The National Grid Corp. of the Philippines (NGCP) said the 69kV line that provides power to the Northern Samar Electric Cooperative (Norsamelco) and the 69kV Taft Feeder transmitting power to the Eastern Samar Electric Cooperative tripped yesterday.
The grid operator said in its Twitter account that efforts to restore power will start as soon as the weather improves.
Energy Secretary Jericho Petilla warned in a radio interview that distribution lines which source power from transmission lines, may be toppled by the typhoon.
“If they are old, then there is a possibility that they will fall,” Petilla said.
He said the temporary structures that provide grid connections in Cebu, Samar, Leyte and Panay are vulnerable. He added that permanent structures take a year to complete.
Petilla said he hopes Ruby would not cause massive damage to power lines unlike Super Typhoon Yolanda (international name: Haiyan) that plunged several provinces in darkness last year.
NGCP personnel had been working to restore power in Albay which was hit by an outage because of a toppled pole.
Customers of the Albay Power and Energy Corp. were affected by the outage.
The power transmission company restored power in Albay after re-energizing the Tiwi-Malinao-Tabaco 69kv transmission line.
