📢 LUZON GRID ALERT ADVISORY
Update as of May 15, 2026 | 11:45 AM
The Luzon Grid continues to face a power supply deficit and remains under extended Red and Yellow Alert status today.
Despite the restoration of the Tayabas-Ilijan and Dasmariñas-Ilijan 500kV transmission lines last May 13, the grid is still experiencing a total of 4,828MW unavailable capacity due to forced outages and derated power plants. The situation was further aggravated by the tripping of GNPD Unit 1, resulting in the loss of 668MW.
Peak demand is expected to reach 12,927MW, exceeding the available capacity of 12,075MW.
🕒 ALERT SCHEDULE:
🟡 YELLOW ALERT: 1:00 PM – 2:00 PM
🔴 RED ALERT: 2:00 PM – 11:00 PM
🟡 YELLOW ALERT: 11:00 PM – 12:00 AM
We are continuously monitoring the situation as we wait for all affected plants to resynchronize back to the grid. Stay tuned for further updates.

The extension of the Red and Yellow Alerts is due to the tripping of GNPD Unit 1, resulting in the loss of 668 MW and further aggravating the supply deficiency.
The Tayabas-Ilijan 500kV Line and the Dasmarinas-Ilijan 500kV Line were restored on 13 May 2026 at 2:44PM and 4:52PM, respectively. We are waiting for all the affected plants to resynchronize back to the grid.
A red alert status is issued when power supply is insufficient to meet consumer demand and the transmission grid’s regulating requirement.
A yellow alert is issued when the operating margin is insufficient to meet the transmission grid’s contingency requirement.
