The National Grid Corp. of the Philippines (NGCP) placed the Luzon grid on yellow alert on Tuesday morning until the afternoon due to low power reserves.

According to an advisory from the power-grid operator, the yellow alert will last from 11 a.m.  to 4 p.m.

The NGCP said the Luzon grid has low contingency reserves brought by insufficient power supply at 10,170 megawatts (MW) and a demand of 8,958 MW. The reserves total 1,212 MW.

Luzon’s largest distribution utility, the Manila Electric Co. (Meralco), tapped its Interruptible Load Program (ILP) participants to deload their consumption from the grid through their generator sets.

The distribution utility further explained the following units of power plants are offline: the 302-MW GN Power Unit 1, the 140-MW Southwest Luzon Power Generation Corp. unit 1 and the 50-MW Angat Main unit 2.

The Pangilinan-led firm further said two units are also on maintenance shutdown, namely, the 382-MW Pagbilao Unit 2 and the 180-MW Kalayaan Unit 3.

The power company also said Calaca Unit 1 was derated to 180 MW, from 200 MW, while Malaya 2 has a lower capacity at 150 MW, from 350 MW.

Meralco also advises its customers to practice energy-efficiency due to the limited supply.
