The Visayas power grid was placed under yellow alert on Monday, marking the sixth alert for the region this month due to ongoing power plant outages and reduced electricity supply.
The National Grid Corporation of the Philippines (NGCP) said the alert was raised from 3 p.m. to 9 p.m. as available power capacity remained only slightly higher than expected peak demand. A yellow alert means power reserves are low, although widespread outages are not yet expected.
NGCP reported that several power plants remain offline because of forced outages, while others are operating below normal capacity, resulting in more than 845 megawatts of unavailable power in the Visayas grid.
The Visayas Grid has been under yellow alert for six days this May and also experienced red alerts from May 13 to 15, indicating a more serious power shortage during those periods. The Luzon Grid also faced red and yellow alerts earlier this month.
Energy officials said the power situation in Luzon has improved after some plants resumed operations. The Department of Energy also expects conditions to gradually improve with the start of the rainy season, which could boost hydroelectric power production and lower electricity demand due to cooler weather.
However, authorities warned that possible El Niño conditions later this year could still trigger additional power alerts, prompting continued coordination between government agencies and the energy sector to prevent supply disruptions.
