The Luzon grid on Tuesday was under red alert from 10 a.m. to 5 p.m. and 6 p.m. to 10 p.m., and yellow alert status from 9 a.m. to 10 a.m., 5 p.m. to 6 p.m., and 11 p.m. to midnight, the Department of Energy said.

The agency said the 316-megawatt GMEC Coal-Fired Power Plant Unit 2 went offline at 3:56 a.m. Tuesday due to a suspected boiler tube leak.

“The plant is expected to be back online by 8 June 2021,” it said.

This is on top of the reported power plants that were on outage Monday including the GNPower Dinginin Coal-Fired Power Plant Unit 1, San Roque Hydroelectric Power Plant, and Sual Coal-Fired Power Plant Unit 2.

From 1,285 MW forced outages on Monday, this has increased to 1,579 MW Tuesday.

The available power capacity on Tuesday also declined to 11,408 MW from the previous day’s reserve of 11,729 MW, while peak demand is slightly higher from Monday’s 11,514 MW to this day’s 11,593 MW power requirement.

“In order to maintain a balanced system, NGCP (National Grid Corporation of the Philippines) may implement manual load dropping (MLD) in parts of Luzon today to maintain the integrity of the power system,” DOE added.

In a separate advisory, NGCP listed scheduled MLD or rotating brownouts in parts of Isabela, parts of Nueva Ecija, parts of Pangasinan, parts of Bataan, parts of Batangas, parts of Camarines Sur, parts of Metro Manila, and the province of Ifugao.

Power supply for vax storage

Department of the Interior and Local Government (DILG) Undersecretary Jonathan Malaya told reporters that the agency has reminded local government units (LGUs) to secure an uninterruptible power supply in cold storage facilities of coronavirus disease 2019 (Covid-19) vaccines.“At this time of pandemic, vaccines are more valuable than gold and therefore contingency plans should be implanted soonest to mitigate the rotational brownouts being implemented by the NGCP,” Malaya said.
