MANILA (UPDATE) - The Luzon grid was placed under red alert on Tuesday with potential power outages due to low power supply, the National Grid Corporation of the Philippines said. 

The red alert status is in place from 10 a.m. to 5 p.m., the NGCP said in an advisory.

The grid will remain on red alert from 6 p.m. to 10 p.m. Tuesday, it added.

Yellow alert was earlier raised from 9 a.m. to 10 a.m. It will also be in place from 5 p.m. to 6 p.m. and 10 p.m. to 12 a.m., it said.

The available capacity on June 1 is at 11,480 MW while the peak demand could reach 11,593 MW.

Manual load dropping could be implemented to balance out supply, the NGCP said. Rotational power outages were also implemented on Monday.

Manual load dropping may be implemented in the following areas:

10 a.m. to 11 a.m.

  • BENECO (parts of Baguio City and Benguet)
  • NEECO II-Area 1 (parts of Nueva Ecija)
  • SAJELCO (San Jose City, Nueva Ecija) 
  • PAMES (Pantabangan, Nueva Ecija) 
  • QUEZELCO I (parts of Quezon)
  • SORECO I (parts of Sorsogon)
  • MERALCO (parts of Metro Manila)

2 p.m. to 3 p.m.

  • ISELCO I (parts of Isabela)
  • IFELCO (Ifugao province)
  • NEECO I (parts of Nueva Ecija)
  • DECORP (Parts of Pangasinan) 
  • CENPELCO (Parts of Pangasinan)

  • FLECO (parts of Laguna)
  • QUEZELCO II (parts of Quezon)
  • SORECO (parts of Sorsogon)
  • MERALCO (parts of Metro Manila)

"Schedule may be cancelled if system condition improves, such as if actual demand falls below projections," the NGCP said. 

"NGCP encourages everyone to exercise prudence in using electricity," it added.

The high heat index, unscheduled maintenance works, and low-yield in supply were among factors that contributed to supply issues, the Department of Energy earlier said.

The DOE on Tuesday said "enforcement issues" on power players also contributed to the lack of power supply in Luzon.

The NGCP was unable to comply with its ancillary services, which is included in its obligations under its franchise, an energy official said Tuesday.

Authorities earlier warned of persistent power interruptions in the next few days due to low power supply.
