MANILA, Philippines – The Luzon grid went on red alert from 1 pm to 5 pm on Monday, September 12, which meant there was insufficient power supply and rotational brownouts could happen.

The grid was also on yellow alert, meaning low power supply, initially from 9 am to 1 pm and then from 5 pm to 8 pm.

The National Grid Corporation of the Philippines (NGCP) said seven power plants were on forced outage, while three others were running on derated or reduced capacities.

As a result, 3,627 megawatts (MW) were lost from the Luzon grid.

The NGCP provided the list of areas which may be affected by manual load dropping or rotational brownouts:

1 pm to 2 pm
  • Manila Electric Company (Meralco) – parts of Metro Manila
  • BENECO – parts of Baguio City and Benguet
  • PRESCO and PELCO I – parts of Pampanga
  • QUEZELCO I – parts of Quezon
2 pm to 3 pm
  • Meralco – parts of Metro Manila
  • INEC – parts of Ilocos Norte
  • BENECO – parts of Baguio City and Benguet
  • CAGELCO II – parts of Cagayan and Apayao
  • AEC – Angeles City
  • FLECO – parts of Laguna
  • QUEZELCO II – parts of Quezon
  • CASURECO II – parts of Camarines Sur
  • APEC – parts of Albay
3 pm to 4 pm

  • INEC – parts of Ilocos Norte
  • BENECO – parts of Baguio City and Benguet

  • PELCO II – parts of Pampanga
  • FLECO – parts of Laguna

  • BATELEC II – parts of Batangas
  • SORECO I and II – parts of Sorsogon

Separately, Meralco had advised its customers to expect rotational brownouts due to the grid’s red alert status.

Meralco covers Metro Manila, Rizal, Cavite, and Bulacan, as well as parts of Pampanga, Batangas, Laguna, and Quezon.

The NGCP had said rotational brownouts may be canceled if the system condition improves, “such as if actual demand falls below projections.”

The red alert was eventually lifted at 5 pm, with available capacity at 10,693 MW and peak demand at 9,933 MW. – Rappler.com

    I saw a news clip on YouTube just a while ago saying another yellow alert would still be on from 4pm to 7pm this evening. So we’re not yet out of the woods until later tonight.
