Power interruptions continue in NCR as NGCP maintains power supply back to normal


A day after a massive power outage hit Luzon, some areas in Metro Manila were still experiencing power interruptions early Thursday morning. 
 
The affected areas include parts of Quezon City where power was restored Wednesday night but went out again before dawn Thursday, radio dzBB's Allan Gatus reported.
 
However, the Department of Energy maintained power had been restored as of Wednesday night, and the Thursday morning outages could be "localized."
 
"Baka 'yan ay localized. Baka within the distribution system," DOE Electric Power Industry Management Bureau Director Mylene Capongcol said in an interview on dzBB radio.
 
She said that as of 11:50 p.m. Wednesday, power had been restored and the yellow notice reflecting a deficiency in reserve power had been lifted.
 
The National Grid Corporation of the Philippines said that as of 6 a.m., there was a reserve of 262 megawatts for Luzon, whose system capacity outlook for Thursday was at 8,567 megawatts.
 
For Visayas, it said the system capacity outlook was at 1,803 megawatts, with reserves of 359 megawatts.
 
Investigation
 
Capongcol said their initial investigation showed a failure in the special protection system of the Calaca Unit 2 and the Calaca Biñan line that eventually cascaded and resulted in the loss of 3,500 megawatts.
 
She said the DOE has tasked the NGCP to complete its evaluation.
 
Also, she said the DOE asked the Philippine Independent Power Producers Association to submit logs of the generation facilities involved. —KG, GMA News
