The Visayas power grid was placed on yellow alert again on Wednesday, June 12, due to insufficient operating reserves. The National Grid Corporation of the Philippines (NGCP) issued the alert from 1 p.m. to 4 p.m., warning of potential power interruptions if the situation worsens.
A yellow alert indicates that the grid's operating margin is thin, but does not necessarily mean there will be blackouts. The NGCP attributed the alert to several power plants going on unplanned outages or running at reduced capacity.
This marks the second time in less than a week that the Visayas grid has been placed on yellow alert, raising concerns about the reliability of power supply in the region. Energy officials are urging consumers to conserve electricity during peak hours to help stabilize the grid.
