MANILA, Philippines – The Luzon grid is on red alert from 1 pm to 4 pm on Monday, September 12, which means there is insufficient power supply and rotational brownouts may happen.
The grid is also on yellow alert, meaning low power supply, from 9 am to 1 pm and from 4 pm to 9 pm on Monday.
The National Grid Corporation of the Philippines (NGCP) said seven power plants are on forced outage, while three others are running on derated or reduced capacities.
As a result, 3,627 megawatts have been lost from the Luzon grid.
The NGCP provided an initial 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 1 – parts of Pampanga
- QUEZELCO 1 – parts of Quezon
Separately, Meralco 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 said rotational brownouts may be canceled if the system condition improves, “such as if actual demand falls below projections.” – Rappler.com
