The entire Bago City was hit with a blackout  late morning yesterday after the defective 5MVA Calumangan substation transformer of the Central Negros Electric Cooperation bogged down at around 11:20 a.m.

Roel Venus, head of Cooperative Promotion Section, said power was expected to resume Wednesday midnight after CENECO requested Negros Occidental Electric Cooperative to supply 4.2 megawatts from its Pulupandan substation to Bago.

The remaining .8 megawatts will be sourced from the CENECO Sum-ag substation.

Bago, situated more than 21 kilometers south of Bacolod, has about 12,000 registered CENECO consumers.

The Calumangan substation has an internal defect. It is old and its lifespan has probably been used up, Venus said.

He said it will be replaced by CENECO’s spare transformer that will take 48 hours to install, from the start of the power interruption.*NLG
