MANILA, Philippines — Rotational brownouts may hit parts of Luzon and Metro Manila again on Wednesday as power supply continues to remain low, the National Grid Corporation of the Philippines (NGCP) said.

In an advisory, the NGCP said it may implement manual load dropping (MLD) in the following areas from 11 a.m. to 12 noon to “maintain the integrity of the power system”:

  • CAGELCO II (parts of Cagayan)
  • PELCO I (parts of Pampanga)
  • APEC (parts of Albay)
  • MERALCO (parts of Metro Manila)

An MLD is implemented in areas at a specific time due to a low power supply.

“Schedule may be cancelled if system condition improves, such as if actual demand falls below projections,” it said.

The grid operator once again placed the Luzon grid under yellow and red alert statuses on Wednesday.

In its advisory, the yellow alert is in place from 8 a.m. to 9 a.m., then from 5 p.m. to 6 p.m., and then by 11 p.m. to 12 a.m.

The red alert is raised from 9 a.m. to 5 p.m. and then from 6 p.m. to 11 p.m.

The NGCP said the available capacity is at 11,260 megawatts (MW), while the operating requirement is at 11,976 MW. The operating margin deficiency is at – 716.

“NGCP encourages everyone to exercise prudence in using electricity,” it said.

This is the third straight day that the Luzon grid was placed under red and yellow alerts amid thin power reserves resulting from planned and unplanned outages of several power plants.

The Department of Energy earlier said that the power supply situation is expected to normalize by June 8 when a power plant that went on forced outage will come back online.

Red alert sa Luzon power grid, posibleng itaas hanggang sa susunod na linggo — DOE

MANILA, Philippines — Posibleng muling ilagay sa red alert status ang Luzon power grid sa susunod na linggo dahil sa problema sa supply ng kuryente.

Sa pagdinig ngayong Biyernes ng House Committee on Energy, sinabi ng Department of Energy (DOE) na maaaring maging mahigpit pa rin ang supply ng kuryente kung hindi pa magbabalik-operasyon ang alinman sa mga plantang nagsagawa ng emergency maintenance.

“Ano naman yung ating nakikita for the next weeks? Yung end of this week hanggang next week, nakikita na kung walang makakapasok na planta, below the red line pa rin tayo,” ang wika ni Energy Undersecretary Mario Marasigan.

“So kulang pa rin yung ating regulating reserves, magkakaroon pa rin tayo ng red alert,” dagdag pa niya.

Bagaman ilalagay sa yellow alert ang power grid, tiniyak naman ng DOE na hindi na magpapatupad ng rotational brownouts.

Noong Mayo 31, at Hunyo 1 hanggang 2 ay isinailalim sa red at yellow alerts ang Luzon power grid dahil sa mataas na demand at mababang power supply.

Paliwanag ni Energy Secretary Alfonso Cusi, sapat ang supply ng kuryente bago nangyari ang rotational brownout ngunit nagkasabay ang pagtaas ng demand dahil sa mainit na panahon at pagbagsak ng ilang planta.

Aniya, ang iba sa mga planta sa bansa ay luma na ay kailangan na ng madalas na maintenance.

Nakadagdag pa sa delay ng maintenance ng mga planta ang hindi agad pagdating ng spare parts at technical personnel dahil sa pandemya.

“Ito pong pagkawala, the last 2 days ng supply is because po yung pagka sabay-sabay ng pagkasira nung 4 na malalaking planta po. That we lost around 2,000 megawatts,” ang wika ni Cusi.

Samantala, sinabi naman ng Energy Regulatory Commission na pinagpapaliwanag na nito ang nasa 35 generation companies dahil sa pagdami ng unplanned outages mula buwan ng Enero hanggang Abril ngayong taon.

Ayon kay ERC chairperson Agnes Devanadera, 13 sa mga ito ang tumugon sa kanilang direktiba habang ang iba naman ay idinahilan umano ang pagiging luma ng kanilang mga planta at delay sa proseso ng maintenance.

Kasama rin aniya sa iniimbestigahan ng ERC ang posibilidad na sabwatan o pananabotahe sa supply ng kuryente upang pataasin ang presyo nito.

“Kung wala namang maibibigay na ebidensya ay hindi naman namin pwedeng tanggapin yung ganun. So ang nararapat na kaparusahan ay kailangan ipataw naming,” ang wika ni Devanadera.

Sa huling linggo ng Hunyo at sa pagpasok pa ng buwan ng Hulyo inaasahan ng DOE na maibabalik sa normal ang supply ng kuryente kapag nagbalik-operasyon na ang mga nag-shutdown na plant at bumaba na ang konsumo. RRD (mula sa ulat ni Correspondent Rey Pelayo)

Luzon grid in normal condition, no power outages within Thursday — DOE

Robie de Guzman   •   June 3, 2021

MANILA, Philippines — The Luzon grid is now in normal system condition after three straight days of being placed under red and yellow alerts, the Department of Energy (DOE) said Thursday.

“As of 9:00 AM, the Luzon Grid is in normal system condition. There are currently enough power supply reserves to accommodate the projected demand, which has significantly decreased due to adverse weather conditions,” the DOE said in an advisory.

“Barring any sudden increase in demand, no rotational outages are expected to happen within the day,” it added.

The National Grid Corporation of the Philippines (NGCP) first placed the Luzon grid under red and yellow alerts on May 31, and then on June 1 and 2 due to low power supply following planned and unplanned outages of some power plants.

The DOE said the power supply has normalized Thursday as the NGCP projected a total available capacity of 11,601 megawatts (MW), relative to the projected peak demand of 10,331 MW as of 9:00 a.m. Thursday.

The department, however, noted that power plants with a capacity of 435 MW are still on planned outage while those with 1,314 MW capacity are on a forced outage.

It also said that the Iljan power plant reduced its output to 716 MW from 835 MW in the previous week due to the ongoing Malampaya gas restriction.

“Pagbilao Coal-Fired Power Plant Unit 2 (382 MW), which is currently on forced outage since June 2, 2021, is expected to return to service on June 6, 2021,” the DOE said.

“GNPower Mariveles Energy Center (GMEC) Coal-Fired Power Plant Unit 2 (316 MW), which is currently on forced outage since June 1, 2021, is expected to return to service on June 8, 2021,” it added.

The agency also reported that the GNPower Mariveles Energy Center (GMEC) Coal-Fired Power Plant Unit 1 (316 MW), which is currently on forced outage since February 6, 2021, is expected to return to service on August 31, 2021.

While the Sem-Calaca Coal-Fired Coal-Fired Power Plant Unit 2 (300 MW), which is currently on forced outage since December 3, 2020, is expected to return to service on July 1, 2021.

The DOE assured it continues to monitor the power situation and will regularly provide updates on the status of the power supply.

“We have been working closely with the other enforcement agencies in pursuing options available to us to ensure that unplanned, prolonged, and perhaps even alleged malicious activities of certain players in the energy sector are scrutinized, investigated, and possibly penalized by the Energy Regulatory Commission (ERC), the Philippine Competition Commission, and the Department of Justice,” it said.

The DOE likewise reminded distribution utilities as well as the system operator of their contracting obligations to address the needed capacity increases for a reliable power system for its consumers.

“The DOE is pursuing its long term strategy of addressing the power supply and demand situation during the summer season and forward to the resumption of our country’s economic activities and recovery,” it said.

“We have put in place redundancies and even double redundancies to ensure the safe storage of our vaccines especially during this crucial period in our government’s vaccine rollout, and have laid out contingencies for the stable, reliable and accessible power for all,” it added.

Red, yellow alerts over Luzon grid now lifted — NGCP

MANILA, Philippines — The National Grid Corporation of the Philippines (NGCP) has lifted the red and yellow alerts it earlier raised over the Luzon grid.

“As of 3:21 PM, red and yellow alerts have been lifted by NGCP for the Luzon grid due to receding system demand,” the NGCP said in an advisory.

Earlier in the day, the NGCP placed the Luzon grid under yellow alert from 8 a.m. to 9 a.m., then from 5 p.m. to 6 p.m., and then by 11 p.m. to 12 a.m. The red alert is raised from 9 a.m. to 5 p.m. and then from 6 p.m. to 11 p.m.

The NGCP said the available capacity is at 11,260 megawatts (MW) while the operating requirement is at 11,976 MW. The operating margin deficiency is at – 716.
