Red alert raised for 4th time in Luzon grid

MANILA, Philippines (UPDATED) – Power interruptions are expected on Monday, April 15, as the Luzon grid was placed under red and yellow alerts for the 4th time this month.

The National Grid Corporation of the Philippines (NGCP) placed the Luzon grid on red alert from 10 am to 11 am and from 1 pm to 4 pm on Monday. This means that power companies may implement rotational brownouts.

The yellow alert was also raised from 9 am to 10 am, from 11 am to 1 pm, from 4 pm to 5 pm, and from 6 pm to 8 pm. This is one notch lower than the red alert and means that reserves have dropped below 647 megawatts (MW). A yellow alert status does not result in power interruptions.

The Manila Electric Company (Meralco) released a tentative list of areas to be affected by rotational brownouts on Monday. Below is the list as of 12:40 pm:

Between 1 pm and 2 pm





"The red and yellow alerts have been caused by insufficient operating reserves due to the forced outage of multiple power plants," the Department of Energy (DOE) said.

In addition to the plants on forced outage, several plants are also running below their maximum capacities.

To avert the possibility of a power interruption during the red alert status, energy companies will implement the Interruptible Load Program.

Establishments which are part of this program will use their own generators during power supply deficits.

The DOE appealed to consumers to conserve energy to help mitigate the impact of low power supply in the grid. –
