The National Grid Corporation of the Philippines (NGCP) on Monday announced that the Luzon grid was placed again under yellow alert from 2 p.m. to 4 p.m.
The NGCP defines yellow alert as a system condition in which the power reserves are less than the capacity of the biggest plant online, which is 647 megawatts for Luzon. The alert does not necessarily mean that power interruptions will occur.
The Luzon grid’s available capacity is 11,286 MW against an expected peak demand of 10,438 MW.
Last Friday, the Luzon grid was also put under yellow alert due to thinning reserves following the unplanned shutdown of some power plants.
The Department of Energy (DoE) has assured the public that the power supply is sufficient and there will be no interruptions expected despite the series of yellow alerts this summer season.
