The Visayas grid will be under yellow alert status anew for seven hours on Thursday, as major coal plants in the region remain unavailable due to forced outages and derated capacities.In an advisory, the National Grid Corporation of the Philippines (NGCP) said the Visayas grid will be on yellow alert status from 3 p.m. to 10 p.m., May 28.This comes as the available capacity was recorded at 2,532 megawatts (MW) versus the peak demand of 2,388 MW, while a total of 1,006.2 MW remains unavailable to the grid.NGCP said 13 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 14 plants are running on derated capacities.It said the factors that contributed to the yellow alert declaration were the tripping of KSPC 2 and unavailability of Visayas' large coal plants Therma Visayas Inc. (TVI) 1, TVI 2, and Panay Energy Development Corp. (PEDC) 3. A yellow alert is issued when the operating margin is insufficient to meet the transmission grid’s contingency requirement.—AOL, GMA News
