Several power plants were also on emergency shutdown. According to the DOE, Southwest Luzon Power Generation Corp.’s Unit 1 (150 MW) went on emergency shutdown at 9:25 p.m. on Oct. 31 because of boiler tube leak, while the Bacman geothermal power plant (140 MW) Unit 1 was also put on emergency shutdown as a preemptive measure. Unit 2 was put on house load.
The Ilijan power plant in Batangas with a capacity of 1,200 MW went on plant shutdown at 1035 a.m. Sunday a contingency measure to avoid plant damage or sudden disconnection from the grid.
Meanwhile, grid operator National Grid Corp. of the Philippines said eight 230-kV lines remained unavailable.

State-run National Power Corp. said it was continuously conducting intensive monitoring and analysis and disseminating pertinent dam discharge warning information to the public and all concerned agencies.
