Visayas Grid on extended red alert
The Visayas Grid in the Philippines is under an extended red alert due to a significant power supply deficit, leading to rotational brownouts. The shortage is caused by the unavailability of several major coal-fired power plants and limited energy imports from Mindanao.
Why it matters
Recurring power grid instability in the Visayas region threatens local economic activity and highlights the vulnerability of relying on aging energy infrastructure.
CEBU, Philippines - The Visayas Grid was placed under an extended red alert on Tuesday, August 11, resulting in rotational brownouts and manual load dropping across several distribution utilities, including Cebu City.
The National Grid Corporation of the Philippines (NGCP) reported that the Visayas Grid had only 2,123 megawatts (MW) of available capacity against a projected peak demand of 2,418 MW, leaving a deficit of nearly 300 MW.
The red alert was declared from 3 p.m. to 8 p.m., with yellow alert periods from 1 p.m. to 3 p.m. and again from 8 p.m. to 10 p.m.
For Cebu City residents, the alert meant possible power interruptions in areas served by the Visayan Electric (VECO), which supplies electricity to Cebu City and neighboring municipalities.
NGCP identified VECO and other distribution utilities for potential MLD between 1 p.m. and 10 p.m.
