A massive power outage caused by the trip off of a 138 kv power line of the National Grid Corporation of the Philippines (NGCP) rendered major provinces and cities in Zamboanga Peninsula powerless for hours yesterday.

Residents endured the searing heat of summer as generator sets lined up the busy downtown area, much like the scenes from years past when the city used to experience long power outages.

A National Grid Corporation of the Philippines (NGCP) advisory released yesterday morning attributed the power outage to problems involving the Agus 5-Aurora 138kv line and the Baloi-Aurora 138 KV line.

The two power lines conked out almost simultaneously starting at 8:34am.

The Baloi Aurora kV line was energized an hour later.

The power outages affected the power distribution of power of electric cooperatives in the Zamboanga Peninsula and parts of Misamis Occidental and Lanao del Norte.

The following electric cooperatives were affected by the power outage:  Zamboanga Electric Cooperative, Zamsureco 1 and 2 based in Ipil and Pagadian, Zamboanga del Norte Electric Cooperative and at least two electric cooperatives in Misamis Occidental.

At around 12:50pm, the Baloi-Aurora 138KV line tripped anew, causing the isolation of all customers served by the Aurora Substation.

Zamcelco General Manager Engr Edgardo Ancheta said that the  Western Mindanao Power Corporation operated on island mode and was able to supply at least 50 percent of the city’s daily power demand.

Normal demand of 92 megawatts a day soared to 103 megawatts due to the intense summer heat.

Power in most areas in Zamboanga, except for the San Jose Gusu feeder, was finally restored at around 3pm. (Liza Jocson)
