The Luzon and Visayas power grids have returned to normal operations after red and yellow alerts were lifted following recent supply shortfalls that led to brownouts in several areas.
In an advisory on Saturday, the National Grid Corporation of the Philippines (NGCP) said both grids were operating under normal conditions based on 6 a.m. data.
The Luzon grid recorded available capacity of 15,799 megawatts (MW) against demand of 12,107 MW, while the Visayas grid posted 2,768 MW in available capacity versus 2,339 MW demand.
The NGCP said the improved supply situation was driven by the return to full capacity of several power units, including GNPower Dinginin Unit 1 (668 MW), Excellent Energy Resources, Inc. Unit 2 (422 MW), and EERI Unit 33 (420 MW), adding a total of 1,510 MW to Luzon’s available capacity.
The transmission operator said the additional supply, combined with lower weekend demand, created excess capacity that also allowed power exports from Luzon to Visayas.
The Department of Energy (DOE) confirmed that both grids were operating normally as of 10:30 a.m. on Saturday.
Red and yellow alerts were lifted late Friday night after reserve levels improved.
A yellow alert is issued when operating reserves fall below required contingency levels, while a red alert indicates insufficient supply to meet demand, often leading to rotational power interruptions.
The NGCP said the power situation is expected to remain stable over the weekend, barring unexpected demand spikes or additional unplanned outages of generation facilities.
The DOE said it continues to coordinate with the Independent Electricity Market Operator of the Philippines, NGCP, Energy Regulatory Commission, generation companies, and other stakeholders to ensure grid stability and consumer protection.
Authorities said they will continue monitoring both grids as the energy situation develops.
