The National Grid Corporation of the Philippines (NGCP) continues to place the Visayas grid under “yellow alert” as available power reserves remain tight. Across several advisories, NGCP cites forced outages or unavailability of multiple large coal-fired generating units as the main reason for reduced supply. The alerts run during late-afternoon and early-evening hours, with schedules varying by day—for example, NGCP issues yellow alert periods from 2 p.m. to 10 p.m. on some days and from about 4 p.m. to 9 p.m. or 5 p.m. to 8 p.m. on others. NGCP says the grid can still meet demand under yellow alert conditions, but the operating margin falls below the level required to meet contingency requirements, meaning a single additional plant outage could trigger brownouts. The operator reports available capacity figures in the range of about 2,523 MW to 2,691 MW and peak demand projections that are close to those levels, leaving thin margins. Some reports also reference expectations that certain coal facilities will return to commercial operations by August, but the alerts persist because outages continue to constrain supply.
