Visayas grid under yellow alert on Wednesday, Nov. 19, 2025 — NGCP
The Visayas power grid was placed on a yellow alert by the National Grid Corporation of the Philippines (NGCP) from 3 p.m. to 8 p.m. on Wednesday, November 19, 2025.
This alert signifies that the operating margin is insufficient to meet the transmission grid's contingency requirement, increasing the risk of power interruptions.
The Visayas grid had an available capacity of 2,694 megawatts against a peak demand of 11,829 megawatts.
A total of 898.6 MW was unavailable due to 14 plants on forced outage, some since April 2025 and others dating back to 2023 and 2024.
Additionally, 14 plants were operating at reduced capacities.
The unavailability of TVI 1 and 2 (169MW each) and the emergency shutdown of LGPP 3 contributed to the yellow alert.
