The power distributor also reminded the public to be energy efficient to help prevent brownouts by unplugging appliances that are not being used, avoid frequently opening and closing refrigerators and to clean electric fan blades and aircon vents for optimal use.

Luzon Grid under yellow alert status on July 13 – NGCP

MANILA, Philippines – The National Grid Corporation of the Philippines (NGCP) placed the Luzon Grid under yellow alert status on Tuesday, July 13.

In an advisory, the NCGP said the yellow alert status will be raised over the Luzon Grid from 10 a.m. to 11 a.m. and from 12 p.m. to 2 p.m.

A yellow alert means that the grid has thin reserves based on the supply and demand but does not necessarily mean power outages.


The grid operator said four power plants are on unplanned outage while three plants have derated capacities, resulting in 1,522 megawatts (MW) unavailable energy.

The following plants are on unplanned outage:


  • QPPL – 460MW
  • Pagbilao Unit 2 – 382MW
  • GMEC Unit 1 – 316MW
  • Calaca Unit 2 – 300MW


The plants with derated capacities are listed below:


  • SLPGC Unit 1 – 145MW (derated by 5MW)
  • SLPGC Unit 3 – 23MW (derated by 2MW)
  • Sual Unit 2 – 590MW (derated by 57MW)


The NGCP said the available capacity is 11,067 MW while the operating requirement is at 10,924MW. This resulted to a net operating margin of 143MW.

Singil sa kuryente ng Meralco, tataas ngayong Hulyo

Robie de Guzman   •   July 9, 2021

MANILA, Philippines — Muling magpapatupad ng dagdag singil sa kuryente ang Manila Electric Company (Meralco) para sa buwan ng Hulyo.

Ayon sa Meralco, nasa P0.23 kada kilowatt hour (kWh) ang madaragdag sa babayaran ng mga consumer ngayong buwan.

Ibig sabihin, may dagdag na P47 ang bill sa kuryente ng mga kumukonsumo ng 200 kWh kada buwan, P70 para sa 300 kWh, P94 para sa 400 kWh, at P117 naman sa mga umaabot ng 500 kWh ang buwanang konsumo.

Ayon sa Meralco, ang dagdag singil ay bunsod ng pagtaas ng presyo ng kuryente sa spot market at iba pang power supplier.

Ito na ang ika-apat na sunod na buwan na nagtaas ng singil ang Meralco.

No brownouts? DOE expects better power situation during rainy season

MANILA, Philippines – The Department of Energy (DOE) has assured residents in Luzon that there is no need to fear power outages on Monday after the National Grid Corporation of the Philippines (NGCP) raised a yellow alert over Luzon grid.

The NGCP on Monday morning placed the Luzon grid under the second highest alert due to reduced net operating margin after the operating requirement stood at 11,344 megawatts (MW) against the available capacity of 11,760 MW.

According to Energy Undersecretary Felix Fuentebella, the yellow alert status was raised after a power plant encountered some problems.

“Meron tayong yellow alert ‘pag nagkakaroon ng manipis, hindi naman siya kulang, pero manipis iyong supply,” he said during the Laging Handa public briefing. “Yellow alert means wala tayong aasahan na rotational brownout or power interruption.”

“We are expecting anytime soon, kung walang madadagdag pang aberya sa ibang planta, all things go well, as planned, mali-lift na po ‘yong yellow alert. So wala tayong masyadong dapat ipangamba,” he added.

The NGCP later lifted the yellow alert “due to sufficient generating capacity.”

Fuentebella said the DOE is expecting a better power situation in the country in the coming weeks due to declining demand amid the rainy season.

“Pababa na po ang demand, ibig sabihin po niyan ay nagkakaroon na ng mas malamig na panahon, medyo cloudy po ngayon kaya mas bumababa po ang paggamit natin ng kuryente,” he said.

“At dahil po diyan ay we anticipate a better scenario for our country and for the power system,” he added.

Earlier this month, parts of Luzon experienced power outages due to a shortage in energy supply after several plants went offline.

The DOE earlier said that Luzon grid might still be placed under yellow or red alert levels until July due to the scheduled maintenance activities of some power plants.
