The Luzon grid was placed on yellow alert for the second consecutive day this year.

The National Grid Corporation of the Philippines (NGCP) issued the notice on Tuesday, placing the grid on yellow alert from 10 a.m. to 11 a.m. and from 1 p.m. to 8 p.m. due to insufficient operating reserve.

The grid’s available capacity stood at 10,278MW while operating requirement was at 9,526MW, leaving a margin of 388MW only.

This was mainly due to the forced outage incidents of GNDP Unit 1 (668MW), GN  Power Unit 2 (316MW), Calaca Unit 2 (300MW), and Avion 1 (47MW).

Also, the derated power plants contributed to the grid’s thin supply. These are the Ilijan, derated by 505MW; Masinloc Unit 2, by 39MW; Magat, by 180MW; San Gabriel, by 210MW.

In all, 2,265MW were shaved off the Luzon grid.

These are same plants that were reported to have derated capacities and went on forced shutdown last January 10.

NGCP is a privately owned corporation in charge of operating, maintaining, and developing the country’s state-owned power grid, an interconnected system that transmits gigawatts of power at thousands of volts from where it is made to where it is needed.
