NGCP: Visayas grid on yellow alert on Monday, June 1, 2026

The Visayas grid will be placed under yellow alert status anew for six hours on Monday due to the continued forced outages of major coal plants in the region and the expected high system demand.

In an advisory, the NGCP said the Visayas grid will be on yellow alert status from 3 p.m. to 9 p.m.

The yellow alert indicates that the operating margin is insufficient to meet the transmission grid’s contingency requirement.

This comes as the available capacity was recorded at 2,579 megawatts (MW) versus the peak demand of 2,488 MW as a total of 958.25 MW remains unavailable to the grid.

The NGCP said 11 plants are 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 11 plants are running on derated capacities.

It said the factors that contributed to the yellow alert declaration are the unavailability of Visayas' large coal plants Therma Visayas Inc. (TVI) 1, TVI 2, Panay Energy Development Corp. (PEDC) 3, and KSPC 2, and high system demand forecast.
