Transco clarifies power outage in Southern Mindanao
General Santos City (19 September) -- The National Transmission Corporation (TransCo) has issued an apology to electricity consumers in southern Mindanao following the series of power interruptions in the region Monday.
"We are truly sorry for the inconvenience and problems brought by the repetitive outages to the people in Mindanao. Notwithstanding our operational vigilance, things like this happen on rare occasions. But we know this is not an excuse for taking long to solve the problem. We owe it to the consumers to give them reliable power," TransCo President & CEO Arthur N. Aguilar added.
Technical investigations revealed that the power outages were caused by a malfunctioning transmission line protective relay at the Kibawe substation in Bukidnon. The said protective equipment caused adjacent incoming and outgoing transmission lines to trip.
To prevent a recurrence of the problem, Aguilar said he has ordered a thorough rechecking of all the remaining 68 protective relays installed in strategic substations throughout Mindanao despite the fact that these equipment have been checked earlier as part of their preventive maintenance schedules.
TransCo will also immediately install additional transient recorders at the Kibawe substation and other substations throughout Mindanao to complement in the determination of the root cause of power outages. A transient recorder is a device that electronically records in minute detail the events that transpired in a particular substation.
Meanwhile, Energy Secretary Angelo Reyes expressed the Department of Energy's appreciation to Davao Light and Power Corporation for helping in power restoration efforts by operating their embedded Bajada Diesel Plant in Davao City.
Areas affected by the power interruption include the provinces of Davao del Sur and Norte, Sarangani, South Cotabato, Sultan Kudarat, North Cotabato, Maguindanao and Shariff Kabunsuan, the cities of Gen. Santos, Cotabato, Tacurong, Kidapawan and Koronadal. (Transco/PIA-SarGen) [top]
