Luzon and Visayas grids to be placed on red, yellow alerts

The National Grid Corporation of the Philippines said Tuesday Luzon and Visayas grids will be placed on red and yellow alert.

According to the NGCP, the Luzon grid will alternately be on yellow and red alert.

Here is the schedule:

Yellow alert

• 1 p.m. to 2 p.m.
• 4 p.m. to 6 p.m.
• 9 p.m. to 11 p.m.

Red Alert

• 2 p.m. to 4 p.m.
• 6 p.m. to 9 p.m.

The Luzon grid has available capacity of 13,537MW and has a peak demand of 13,024MW.

NGCP said 19 power plants are on forced outage, while three others are running on derated capacities, for a total of 2,117.3MW unavailable to the grid.

The Visayas grid, on the other hand, will be on yellow alert from 2 p.m. to 4 p.m. and 6 p.m. to 7 p.m.

It has available capacity of 2,742MW and peak demand of 2,440MW.

At least 12 power plants are on forced outage, while five others are running on derated capacities, for a total of 676.5MW unavailable to the grid.

NGCP said a red alert status is issued when power supply is insufficient to meet consumer demand and the transmission grid’s regulating requirement.

Meanwhile, a yellow alert is issued when the operating margin is insufficient to meet the transmission grid’s contingency requirement.

Earlier this month, the Department of Energy said the power sector is implementing measures to avoid possible power interruptions amid the impact of the El Niño phenomenon and dry season on the country.
