Visayas power grid under yellow alert anew due to thin reserves

The Visayas power grid was placed on a yellow alert by the National Grid Corporation of the Philippines (NGCP) on Wednesday, November 19, 2025, from 3 p.m. to 8 p.m., indicating insufficient operating margin.

The grid experienced another yellow alert on Thursday, November 20, 2025, from 5 p.m. to 7 p.m., due to continued power plant shortfalls and thin reserves.

However, the yellow alert status over the Visayas grid was lifted earlier than expected, at 1 p.m. on Thursday, November 20, 2025.

This lifting occurred as the available capacity improved to 3,044 MW against a projected demand of 2,325 MW.

Multiple power plant outages continue to affect the grid, contributing to the tight supply, including the extended shutdown of TVI Unit 2.

The Luzon and Mindanao grids remained under normal operating conditions.
