Visayas grid on yellow alert as quake hits Cebu

MANILA, Philippines — The Visayas grid was placed under yellow alert for eight hours yesterday after a magnitude 6.9 earthquake struck Cebu and triggered an unplanned shutdown of several power plants.

The alert notice, which was issued when power reserves are low, was raised from 1 p.m. to 9 p.m., according to the National Grid Corp. of the Philippines.

The NGCP said that power grids in Luzon and Mindanao remained normal.

In the Visayas, the earthquake knocked down 11 plants, adding  to the strain caused by 16 other power facilities that have been out of service long before the incident occurred, along with three others that are operating at a reduced capacity.

As a result, 640.6 megawatts of capacity were unavailable to the Visayas grid as of 3 p.m. yesterday, the NGCP said.

Over 800,000 consumer connections across the region experienced blackouts following the earthquake’s impact on 24 power cooperatives, the National Electrification Administration said.

The Department of Energy, meanwhile, has mobilized the entire sector to ensure the immediate restoration of power across affected areas, prioritizing hospitals, water stations and other lifeline facilities.
