BROKEN stand connecting the Agus 7-Agus 6 tie line caused the blackout that hit Mindanao starting around 1 a.m. Sunday, an official of National Grid Corporation of the Philippines (NGCP) said. “May naputol na stand ng Agus 6 - Agus 7 138 kilovolts (kv) tie line, touching one of the CVTs (capacitor voltage transformer) at the switchyard,” engineer Rico Marave, NGCP manager for Power Network Planning Division of Mindanao System Operations, told Edge Davao in a text message yesterday. The incident caused a four-and-a-half blackout in 27 provinces and 33 cities in Mindanao. Power came back
at past 4 a.m. the same day in many areas, although power in some areas were reported to have normalized only at around 10 a.m. This as Energy Secretary Jericho Petillatold ABS-CBN News Channel yesterday that the power outage was caused by a technical problem not by a shortage in the power supply in the Mindanao grid. He also said the island-wide power outage had nothing to do with the power shortage in the Luzon grid. Petilla said the DOE will be investigating the incidentto avoid a recurrence. In Davao City, the blackout also caused a water service interruption that lasted for much of the day. The city’s
water supply serviced by the Davao City Water District (DCWD) is dependent to the Davao Light Power Company DLPC). In a statement, DLPC said some of its feeder lined had no power due to the sudden low frequency or lack of power supply from the Mindanao Grid. These feeder lines were the San Vicente Feeder 4 and 5, Buhangin Feeder 2 and 3, Panacan Feeder 2 and 4, Calinan Feeder 1 and Bunawan Feeder 2. The Easter dawn power outage came 13 months after the February 27, 2014 Mindanao-wide outage which lasted from 3:52 a.m. to 12:18
