NATIONAL GRID Corp. of the Philippines (NGCP) issued a yellow alert twice over the Luzon power grid on Tuesday after five power plant units with a combined capacity of 1,274 megawatts (MW) experienced forced outages.
The yellow alerts were raised at 10-1 a.m. and 1-4 p.m. The second yellow alert was called off by 3 p.m.
A yellow alert is issued during periods when reserves fall below a designated safety margin. It becomes a red alert if the supply-demand balance worsens further, to the extent of requiring rotating brownouts.
The grid operator said the following power plants declared forced outages: unit 1 of GNPower Dinginin Ltd. Co., unit 2 of GNPower Mariveles Energy Center, unit 2 of Calaca Power Station and units 3 and 4 of Southwest Luzon Power Generation Corp.
In addition, unit 1 of Masinloc Power Plant reported that its output was derated to 150 MW from 315 MW.
NGCP is a privately owned company that operates, maintains, and develops the power grid.
President Ferdinand R. Marcos, Jr. has yet to appoint an energy secretary. Also currently unappointed are the heads of the Health, Environment and Natural Resources, Science and Technology, and Human Settlements and Urban Development departments.
According to his chief media officer, the selection process for vacant cabinet posts is now in the final stages, but no target date has been set for announcing the nominees. — Justine Irish D. Tabile
