MANILA, Philippines — The National Grid Corp. of the Philippines (NGCP) said the Luzon power grid will be on yellow alert on Tuesday afternoon after several coal-fired power plants on the island went offline.

A yellow alert is placed over the grid when reserves fall below ideal levels. When the supply-demand balance worsens, a red alert, which points to a severe power deficiency that may lead to rotating power interruptions, is declared.

In a statement on Tuesday, NGCP reported that a total of 1,592 megawatts (MW) have been shaved off from the grid due to the forced shutdowns of coal plants. These are:

• The 460-MW Quezon Power Phils. Ltd. plant;
   
• The Southwest Luzon Power Generation Corp.'s units 1, 3 and 4 (200 MW total);
   
• The GNPower Mariveles Energy Center Ltd. Co. (GMEC) units 1 and 2 (632 MW), and;
   
• The 300-MW SEM Calaca Power Corp. (Calaca) unit 2
