BACOLOD CITY: The six-hour blackout that hit almost the entire Negros Occidental from Saturday night to Sunday morning was caused by lightning that damaged several lightning arresters of the National Grid Corporation of the Philippines (NGCP) in the province.
Power supply was interrupted at around 10:25 p.m. Saturday. Electricity was totally restored in all affected areas at 4 a.m. Sunday.
Sulpicio Lagarde Jr., general manager of Central Negros Electric Cooperative (Ceneco), said their two sub-stations were down that night.
He said the blackout was also experienced by consumers of VMC Rural Electric Service Cooperative Inc. (Vresco) in the north and half of the service areas of Negros Occidental Electric Cooperative (Noceco) in the south.
Electricity in areas covered by Line 1 was back at midnight while in areas covered by Line 2 at about 4 a.m. Sunday, Lagarde said.
“The problem was not the power supply but the distribution of (NGCP),” he pointed.
Lagarde said that another blackout happened at about 7 a.m. yesterday due to the insulator failure of NGCP, but power supply was restored after a short while.
Meanwhile, Lagarde said that Ceneco is assured of sufficient power supply and by June this year, Ceneco will sign a power sales contract with Energy Development Corp. from its geothermal power plant in Nasulo, Negros Oriental.
Ceneco has also signed a contract for a 30-megawatt power supply from Palm Concepcion’s Coal Plant in Iloilo starting 2016. PNA
