MANILA (UPDATE) –– The National Grid Corp on Monday imposed Yellow and Red Alerts, but the latter was lifted after the capacity recovered.
A yellow alert means that power reserves were below ideal levels while red alert indicates insufficient supply which can cause outages in select areas.
The NGCP lifted the Red Alert before noon and retained Yellow Alert from 3 p.m. to 4 p.m. as well as 5 p.m. to 7 p.m.
"Six (6) power plants are on forced outage, while three (3) others are running on derated capacities, for a total of 2,648MW unavailable to the grid," the NGCP said in an advisory.
As of 11:30 a.m., the available capacity is at 11,750 MW with peak demand at 10,437 MW, it said.
In a separate statement, Meralco said there could be possible outages but only if necessary.
"We are monitoring the situation and ready to implement manual load dropping (MLD) or rotating power interruptions if instructed by NGCP as part of our responsibility to manage the system," Meralco said.
