The Visayas power grid in the Philippines is bracing for a third consecutive week of yellow alerts as electricity demand continues to surge, putting pressure on already tight power reserves. According to data from the National Grid Corporation of the Philippines (NGCP), the projected operating margins for the region will range from 201 megawatts (MW) to 223 MW. The highest system peak demand is expected to occur on May 29, reaching 2,549 MW. The region's generating capacity remains stable at around 2,050 MW, but the Visayas grid is heavily reliant on imported power from Luzon and Mindanao to meet its needs. Imports from Mindanao are anticipated to range from 391 MW to 450 MW, while imports from Luzon may vary from zero to 250 MW. The NGCP has noted that any unplanned outages or sudden surges in demand could further strain the grid's operating margins, leading to increased risks of supply disruptions. Yellow alerts indicate that the power supply is insufficient to meet reserve requirements, underscoring the ongoing challenges faced by the Visayas grid during periods of high electricity consumption.
