Visayas power grid placed on yellow alert Monday

The Visayas grid will operate under yellow alert conditions on Monday evening, according to an advisory issued by the National Grid Corporation of the Philippines (NGCP). The alert will remain in effect from 5 p.m. to 6 p.m., a period typically marked by high electricity demand across the region.

Yellow alert status indicates that the power system is operating with reduced reserves, though it remains stable and capable of meeting demand under normal circumstances. The NGCP implements color-coded alert levels to inform stakeholders and the public about grid conditions and potential risks to electricity supply.

The one-hour yellow alert window suggests the NGCP anticipates a temporary tightening of available generating capacity during that specific evening timeframe. Such alerts are typically issued when maintenance activities, equipment outages, or seasonal demand patterns create supply constraints.
