The National Grid Corporation of the Philippines says the tripping of the power plants caused an imbalance in frequency

Power interruptions hit Negros island and Iloilo City on Panay island early morning of Tuesday, October 5, as electric cooperatives shed load  after the tripping of several power plants.

The National Grid Corporation of the Philippines (NGCP) said the tripping of the power plants caused an imbalance in frequency. As of writing power was starting to return to some areas, including San Carlos City in northern Negros Occidental and portions of Iloilo City.

“To maintain the integrity of the transmission grid, protection systems were activated and manual load dropping was implemented. NGCP is waiting for the restoration schedule from the generating plants, and will be announced as soon as possible,” NGCP said in an advisory.

Both Negros Occidental and Negros Oriental experienced power outages.

The Bacolod-city based Central Negros Electric Cooperative (Ceneco) and More Electric and Power Corporation in Iloilo said the NGCP had advised them to shed load.

Ceneco said affected areas included NGCP’s Bacolod-San Enrique 69kV Line; Bacolod-Reclamation and Bacolod-Silay 69kV Lines.

The area includes the Commission on Elections’s city and provincial offices but as of writing, officials said the filing of certificates of candidacy (COC) would continue.

MORE Power affected Iloilo areas include those under Megaworld Feeder 1 (whole Megaworld area), Mandurriao Feeder 3 (SM City Iloilo-Diversion Road area), Mandurriao Feeder 5 (Bolilao and San Rafael areas), and City Proper Feeder 3 (portions of Brgys. San Agustin, Inday, and San Felix). –Inday Espina-Varona and Joseph B.A. Marzan/Rappler.com
