The Visayas grid will be under yellow alert status for seven hours on Thursday, as major coal plants in the region remain unavailable due to forced outages and reduced capacities.

In an advisory, the National Grid Corporation of the Philippines (NGCP) stated that the Visayas grid will be on yellow alert from 3 p.m. to 10 p.m. on May 28.

This comes as the available capacity was recorded at 2,532 megawatts (MW) against a peak demand of 2,388 MW, while a total of 1,006.2 MW remains unavailable to the grid.

NGCP reported that 13 plants have been on forced outage since May 2026, one plant since March 2026, three plants since 2025, two plants since 2024, two plants since 2023, and one plant since 2021, while 14 plants are operating at reduced capacities.

It noted that the factors contributing to the yellow alert declaration were the tripping of KSPC 2 and the unavailability of Visayas’ large coal plants Therma Visayas Inc. (TVI) 1, TVI 2, and Panay Energy Development Corp. (PEDC) 3.
