-
Awaiting deadline 45% Prolonged Grid Instability
The Visayas power grid remains in a fragile state as maintenance delays extend beyond the initial weekend window. NGCP maintains a continuous yellow or elevated yellow alert status throughout the following week, with rolling brownouts reported in key urban centers like Cebu City and Iloilo due to persistent fuel supply bottlenecks.

-
Awaiting deadline 30% Rapid Maintenance Completion
Emergency repair crews successfully accelerate the maintenance work, allowing offline power plants to reconnect to the grid earlier than expected. By Monday morning, the NGCP declares the situation stable and lifts the yellow alert, citing restored reserve margins and normal operational parameters.

-
Awaiting deadline 15% Critical Failure and Blackout
A technical fault during the maintenance window causes a cascading trip at a major power plant, leading to a significant frequency drop. This triggers an automatic under-frequency load shedding event, resulting in a widespread, unplanned blackout across multiple provinces in the Visayas region.

-
Awaiting deadline 10% Regulatory Intervention
In response to the repeated alerts and public outcry over the instability, the Energy Regulatory Commission (ERC) mandates an immediate, third-party audit of NGCP’s maintenance scheduling and fuel procurement processes. This intervention shifts the narrative from technical failure to regulatory scrutiny, forcing NGCP to halt non-critical work for compliance checks.
