NGCP declares yellow alert over Luzon grid

THE National Grid Corp. of the Philippines (NGCP) declared a yellow alert over the Luzon power grid on Monday after more than 1,400 megawatts (MW) worth of plant capacity were reported inoperable.

In an advisory early Thursday, the NGCP said that the yellow alert was raised on Luzon between 3 p.m. and 4 p.m. with peak demand estimated at 13,714 MW for the period, against available capacity of 15,167 MW.

The grid operator said that four plants have been on forced outage since 2023. Three became inoperable between January and March, and nine have been out since April. One plant is running on derated capacity.

As a result of the plant shutdowns and capacity limitations, 1,406.09 MW were unavailable to the grid.

As of the 4:31 p.m., the yellow alert for Luzon had been lifted by the NGCP.

According to the NGCP, the Luzon grid went on red alert for five days and on yellow alert for 11 days in April. The Visayas grid was on red and yellow alerts for five and 10 days, respectively.

The Mindanao grid was on yellow alert for two days during the month.

In May, the NGCP has declared yellow alerts over the Luzon grid for three days.
