Blackout hits parts of Mindanao
MANILA (UPDATE) – Power outages were reported in several parts of Mindanao before dawn on Thursday.
National Grid Corporation of the Philippines (NGCP) Mindanao corporate communications officer Beth Ladaga confirmed that the Mindanao power grid experienced disturbance at 3:53 a.m. today.
Power outage was reported in Zamboanga City, Zamboanga del Norte, General Santos City, Davao City, Davao Norte, Davao del Sur, Davao Oriental, Cagayan de Oro, Cotabato, and Compostela Valley.
The NGCP shifted its operations to "island mode" to restore power in the affected areas.
As of 9:30 a.m., NGCP said transmission service has been restored in Zamboanga City through the Western Mindanao Power Corp.; General Santos City through Southern Philippines Power Corp.; and Davao City through Pulangi IV Hydroelectric Power Plant.
Power has also been restored in Cagayan de Oro, Pagadian City and parts of Misamis Oriental.
Misamis Occidental, Lanao del Sur, Lanao del Norte, and some parts of Northern Mindanao, however, remain without power.
Meanwhile, NGCP spokesperson Cynthia Alabanza said it is still investigating the cause and extent of the power interruption.
"At this time, we have no information on the actual cause because the interruption affected the entire grid of Mindanao... Our focus is still on restoration. When we have finished giving back power to Mindanao grid, then we will focus on the investigation to find out what was the cause of the disturbance," she told ANC.
Alabanza said it is unusual for the entire Mindanao grid to be affected, making it difficult to speculate on the cause.
"While a grid disturbance happens, it could be anything from supply or transmission. It could be anything minor or major, its very difficult to speculate at this point," she said.
The NGCP official said it hopes to restore power within the next few hours. – reports from Roxanne Arevalo, ABS-CBN News Iligan; Lerio Bompat, ABS-CBN News Central Mindanao; and Joel Ramirez, ABS-CBN News Northern Mindanao
