Manila: The yellow alert status for the Visayas grid has been lifted as of 1 p.m. Thursday after demand went down, ensuring an adequate margin of supply.

According to Philippines News Agency, the National Grid Corporation of the Philippines (NGCP) reported that capacity rose to 2,760 megawatts (MW) while demand decreased to 2,421MW. The Visayas grid was previously placed under a yellow alert due to a thin supply margin, which was in effect from 5 p.m. to 9 p.m.

Earlier in the day, there was a 35MW increase in demand, with available capacity at approximately 2,578MW and peak demand at around 2,535MW. The supply issues arose as 10 power plants in the Visayas were on forced outage, and 16 power plant units were operating at derated capacity.

Additional factors affecting the supply included the unavailability of the 103-megawatt coal-fired power plant unit 2 of the Cebu-based KEPCO SPC Power Corporation (KSPC) and a 49MW rise in demand in the Mindanao grid. This increased demand reduced by 207MW the capacity being transferred to the Visayas through the Mindanao-Visayas Interconnection Project (MVIP).

Furthermore, the NGCP noted that the Agus 6 Hydroelectric Power plant was also operating at a derated capacity of 66.5MW during the day.
