• Power supply thins as Calaca plant shuts down


    A unit of the Masinloc coal-fired power plant was shut down early on Tuesday because of a boiler problem but the incident did not cause brownouts despite a thinner power reserve.

    Owned by AES Philippines, Masinloc Coal-fired Thermal Power Plant has a total of 600-megawatt capacity and is connected to the Luzon grid.

    Mylene Capongcol, a director at the Department of Energy, said Masinloc power plant’s Unit 2, which has an output of 300 megawatts, went down at 7:55 a.m on Tuesday.

    “Masinloc 2 went on emergency shutdown starting at 7:55 a.m. due to boiler tube leak,” Capongcol added. She said it may take two to three days to fix the problem.

    Because of the incident, the Luzon Grid was on yellow alert on Tuesday. The National Grid Corp. of the Philippines (NGCP) said the yellow alert may continue until today.

    A yellow alert means power supply is thinner than desired.

    “We expect supply to normalize by Thursday because most offices are closed for the Holy Week break,” NGCP spokesman Cynthia Perez-Alabanza said.

    On Tuesday, the Luzon grid had a capacity of 7,885 megawatts and demand of 7,430 MW.

    Also on Tuesday, Malacañang gave assurances that there is ample power supply in Luzon.

    Presidential Communications Secretary Herminio Coloma Jr. said the Pagbilao plant, with a generating capacity of 300 megawatts, was scheduled to go online on Tuesday.

    Also, the Calaca plant’s generating capacity has been increased from 165 MW to 255 MW, he added.

    The Palace official said the government continues to monitor the power situation nationwide “to ensure stability of supply and electric power rates.”

    “The government is exerting maximum efforts to prevent power outages or brownouts,” Coloma added.
