The National Grid Corporation of the Philippines (NGCP) placed the Visayas power grid under a yellow alert on Monday, May 18, 2026, due to forced outages and derated capacity of several power plants.
In an advisory, the NGCP stated that the yellow alert was issued for the afternoon, indicating that the power supply is insufficient to meet the demand and reserve requirements. The grid operator urged consumers to use electricity efficiently to help maintain stability.
As of the latest data, the Visayas grid had a total available capacity of 2,500 megawatts (MW) against a peak demand of 2,400 MW, leaving a slim margin. The yellow alert is the second-lowest level in the grid's alert system, following a red alert which indicates a more critical shortage.
The NGCP continues to monitor the situation and will provide updates as necessary. The public is advised to stay informed through official channels.
