Blackouts due to technical problems at Calaca 2 - DOE
MANILA -- The brownouts that hit a large part of Luzon on Wednesday were caused by a technical problem in one of the power plants that shut down, Energy chief Jericho Petilla said.
"Kahapon ang nakita nating problema, may isang planta, Calaca 2 (in Batangas), yun ang unang nag-trip na planta saka nagsunud-sunod na ang mga planta, nag-cascade itong lahat," Petilla told ABS-CBN's Umagang Kay Ganda on Thursday.
"Ang iniimbestigahan natin ngayon bakit hindi nag-auto-shut off [ang Calaca]," he continued.
Petilla explained that when a power plant encounters a problem, it should automatically shut down so a back-up generator can start up and replace it to prevent any power interruption.
"Pero kahapon anim ang sunud-sunod [na nag-shut down] dahil may isang planta na for some reason yung auto-shut off niya hindi gumana... Yan ang iniimbestigahan natin ngayon," he said.
He stressed however that after yesterday's metro-wide brownouts, the Calaca 2 plant and transmission lines at the facility have been thoroughly inspected and were all found to be "okay."
"Okay na okay na siya pero sabi ko wala munang magpapatakbo sa plantang yan [at] sa linyang yan hangga't hindi natin alam [ang nangyari]," Petilla said.
Petilla reiterated he does not think Wednesday's incident is related to any plans to sabotage the upcoming elections on Monday.
"Hindi pa rin indication ito na may nagsasabotahe dito, this is more of a technical problem," he pointed out.
"Malalaman lang natin [ang nangyari dito] pag na-analyze na ng NGCP (National Grid Corp. of the Philippines) which is ito ang ginagawa nila ngayon," he said.
