Metro Manila, Philippines – The National Grid Corporation of the Philippines (NGCP) on Thursday placed the Luzon and Visayas grids under red and yellow alert statuses due to insufficient power supply amid high electricity demand.
In Luzon, a red alert will be in effect from 4 p.m. to 10 p.m., while yellow alerts are set from 3 p.m. to 4 p.m. and 10 p.m. to 11 p.m.
Available capacity was recorded at 12,479 megawatts (MW), lower than the projected peak demand of 12,595 MW.
Meanwhile, the Visayas grid will be under red alert from 4 p.m. to 9 p.m., with yellow alerts from 3 p.m. to 4 p.m. and 9 p.m. to 11 p.m.
Available capacity stood at 2,413 MW against a peak demand of 2,541 MW.
NGCP said 21 power plants in Luzon have been on forced outage since January 2026, alongside several others that have remained offline since previous years.
Fourteen plants are also operating on derated capacities, leaving a total of 4,242.5 MW unavailable to the grid.
In the Visayas, 11 plants have been on forced outage since March 2026, while 12 others are running on limited capacity, resulting in 866.7 MW unavailable to the grid.
A red alert status is declared when the power supply is insufficient to meet consumer demand and the grid’s regulating requirement, while a yellow alert is issued when operating reserves fall below the required contingency margin.
