The Visayas grid is placed under yellow alert again on Friday afternoon to evening due to thin supplies brought about by forced outages and derates in capacities of several plants, coupled with high demand amid the hot, dry season weather.In its advisory, the National Grid Corporation of the Philippines (NGCP) said the yellow alert is hoisted from 3 p.m. to 4 p.m. and again from 5 p.m. to 9 p.m.The Visayas grid is running at 2,653 megawatts (MW) capacity against a peak demand of 2,485 MW.READ: What does each power alert level mean?The grid operator said 14 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 12 plants are running on derated capacities, for a total of 885.3 MW unavailable to the grid.It added that among the factors that contributed to the yellow alert declaration are:Unavailability of Visayas' large coal plants TVI 1, TVI 2, and PEDC 3 High forecasted system demandA yellow alert is declared when the power reserve is insufficient to meet the transmission grid’s contingency requirement. While supply is still enough to meet current demand, it no longer reaches the required safety margin.At this level, the possibility of rotational power interruptions increases. —VAL, GMA News
