Brownouts are still possible in Luzon as the Luzon grid was on yellow alert as of Monday morning.

The National Grid Corp. of the Philippines said the Luzon Grid has 156 megawatts of reserve power as of 6 a.m.

It said the grid’s projected capacity for Monday was 6,492 MW, just 156 MW more than the projected system peak demand for the day of 6,336 MW.

NGCP defines a “yellow alert” as a system condition where the total reserve is less than the capacity of the largest plant online. For the Luzon grid, this is 647 MW.

The Visayas grid has only 99 MW of reserve power, as the system capacity is 1,411 MW and projected peak demand is 1,312 MW.

Mindanao has only 7 MW reserve power, with a projected system capacity of 1,191 MW and an expected peak demand of 1,246 MW.

Power has yet to be restored in several areas of southern Luzon, including Metro Manila, in the wake of Typhoon Glenda (Rammasun).

Last weekend, the Manila Electric Co. (Meralco) implemented rotating brownouts in Metro Manila and nearby provinces, citing problems with power plants it draws electricity from.
