May 12 ----- The Department of Energy (DOE) on Thursday said “yellow alerts,” which indicate thinner power reserves to meet any surge in demand, are expected in Luzon during the seven weeks of the summer season—four in May and the first three of June.
“It’s possible that the yellow alerts may occur in any of the seven weeks; after that, it would be about once a month in the second half of the year,” Energy Undersecretary Rowena Guevara said during the televised Laging Handa public briefing.
A yellow alert does not necessarily lead to power outages. Only when a transmission line or power station goes offline and the reserves fail to meet the demand will a red alert be issued, resulting in rotational brownouts. In the Visayas during the same period, the official said yellow alerts were not likely to occur in the daytime but five such alerts were possible in the evenings. She said no yellow alert was anticipated in Mindanao, which has been enjoying a surplus of electricity.
The reopening of the Ilijan power plant in Batangas province on May 26, according to Guevara, would be timely as it could beef up electricity supply in the Luzon grid. “We expect it to contribute 1,200 megawatts (MW) to our (total) power supply and that’s a big thing. If it starts running this May, it’s possible that the yellow alerts anticipated for June would be voided,” Guevara added. As of Thursday, data from the Independent Electricity Market Operator of the Philippines showed that demand in the Luzon grid was at 11,684 MW, while supply stood at 13,300 MW.
