The National Grid Corp. of the Philippines said Tuesday power supply has been restored in Mindanao households and industries affected by a fire that forced the shutdown of two major plants in the island.
National Grid spokesman Cynthia Alabanza said the tripping of Agus 6 and 7 affected power supply to Iligan Light and Power Co. Inc., Lanao del Norte Electric Cooperative and several industries directly connected to the Agus complex.
The Agus 6 and 7 are a part of the Agus-Pulangi power complex which supply about 50 percent of Mindanao’s power requirements.
The Agus power plants supply about 727 megawatts. The fire, which damaged the cables of Agus 6 and 7, reduced the capacity of the Agus complex by 166 MW.
The National Power Corp., which owns the plants, said it was still investigating the cause of the fire.
Alabanza said the National Grid was able to prevent damage and maintain the security and reliability of the Mindanao grid despite the incident by connecting the affected customers to the power grid.
A fire broke out at Napocor’s Agus 6 complex in Iligan City on Saturday, causing National Grid’s 69-kiloVolt lines to trip.
“Power delivery services to all affected customers have been fully restored as of 4:15a.m. of Sept. 4, 2012. Upgraded facilities equipped with anti-fire systems prevented damage on NGCP’s facilities,” Alabanza said.
National Grid embarked last year on 106 operation and maintenance projects, which included 22 anti-fire projects as well as 69 slope protection projects, nine transmission line comprehensive maintenance and six rehabilitation projects.
National Grid also regularly conducts preparedness drills for fires, earthquakes, typhoons, and other disasters which may affect power transmission in its effort to continuously improve and speed up restoration procedures during emergencies. source
