MANILA, Philippines (UPDATE) – The Luzon grid remained on "yellow alert" on Monday due to low power reserves.

After experiencing more than 8 hours of rotating power interruptions last Saturday, Manila Electric Co. (Meralco) said the entire Luzon grid is still on yellow alert, which could result to brownouts if a major plant bogs down.

According to Meralco, although several plants that encountered problems have returned online, these plants are not producing power at full capacity.

These include a unit of Ilijan, which only produces 550 megawatts instead of 600MW; Pagbilao 1, which produces 120MW instead of 328MW; and GNPower 2, which only produces 100MW instead of 302MW.

Meralco spokesman Joe Zaldarriaga said chances are, the alert will not result to brownouts today as the weather remained cool because of the rains brought by tropical storm “Glenda.”

The brownouts that occurred on Saturday were the worst incident for Meralco this year.

The power outage hit portions of Metro Manila, Cavite and Bulacan, affecting over 500,000 households between 10:27 a.m. to 9:20 p.m. on Saturday.
