Luzon Grid under Yellow Alert, to be heightened to Red Alert Monday afternoon

The National Grid Corporation of the Philippines (NGCP) placed the Luzon Grid under Yellow Alert status on Monday morning and is set to heighten this to Red Alert in the afternoon, after the forced outage of at least seven power plants.

In an advisory, the NGCP said the Luzon Grid was placed under Yellow Alert from 9 a.m. to 1 p.m., indicating that the grid has thin reserves based on the supply and demand.

The available capacity was estimated at 10,727 megawatts, with the peak demand seen at 10,585 megawatts.

The Luzon Grid will also be placed under Red Alert from 1 p.m. to 4 p.m. on Monday, indicating that there is zero ancillary services or a generation deficiency exists.

This will then be downgraded back to yellow alert from 4 p.m. to 9 p.m.

According to the NGCP, there were 3,627 megawatts lost from the grid after seven power plants were on forced outage while three were running on derated capacities.  — Jon Viktor D. Cabuenas/RSJ, GMA News
