NGCP: Luzon grid under yellow alert, to be raised to red alert in the afternoon

MANILA, Philippines — The National Grid Corporation of the Philippines (NGCP) placed the Luzon grid under “yellow alert” status on Monday morning.

In an advisory, the NGCP said the Luzon grid was placed under yellow alert from 9 a.m. to 1 p.m.

The yellow alert status is raised when a power grid’s power reserve, or the difference between supply and demand, is below the required level, according to NGCP.

Meanwhile, from 1 p.m. to 4 p.m. Monday, the Luzon Grid will then be placed under “red alert” status, which is put in place when it is likely that the demand will outstrip available generating capacity.

The NGCP said the available capacity was estimated at 10,727 megawatts, while the peak demand is seen at 10,585 megawatts.

It added that there were 3,627 megawatts lost from the grid after seven power plants were on forced outage, while three were running on derated capacities.
