The Visayas grid will be placed on yellow alert on Sunday afternoon, August 16, 2026, until evening due to thin reserves as some power plants are unavailable, the National Grid Corporation of the Philippines (NGCP) said.
In an advisory, the NGCP said the yellow alert will be implemented from 5 p.m. to 10 p.m.
The NGCP said that the grid only has an available capacity of 2,525 megawatts despite a peak demand of 2,480 megawatts.
It noted that among the factors for the declaration of yellow alert on the grid include unavailability of two large coal plants in the Visayas. There was also a limited power import from Mindanao.
