The National Grid Corporation of the Philippines (NGCP) lifted the red alert status over the Visayas grid at 1 p.m. on Wednesday, September 16, 2026.
As of 1:10 p.m., the Visayas grid had an available capacity of 2,584 megawatts (MW), against a peak demand of 2,394 MW.
However, the grid remains under yellow alert until 8 p.m.
According to NGCP, a yellow alert is issued when the operating margin is insufficient to meet the transmission grid’s contingency requirement, while a red alert is declared when power supply is insufficient to meet consumer demand and the transmission grid’s regulating requirement.
Earlier, the Visayas grid was placed under red alert from 5 p.m. to 6 p.m., with yellow alert periods scheduled from 4 p.m. to 5 p.m. and 6 p.m. to 8 p.m.
As of 8 a.m., available capacity stood at 2,536 MW against a peak demand of 2,538 MW.
NGCP earlier cited the unavailability of the Visayas’ large coal plants, TVI 1 and PEDC 3, as well as limited power imports from the Mindanao grid as factors contributing to the red and yellow alert declarations.
The grid also had eight plants on forced outage as of September, along with 15 plants operating at derated capacities, resulting in a total of 774.2 MW of unavailable capacity.
