Metro Manila (CNN Philippines, April 15) — The Luzon grid was placed on alert anew on Holy Monday.

The National Grid Corporation of the Philippines (NGCP) on Monday afternoon lifted the grid's red alert status -- the highest warning -- but said it will remain under yellow alert until 8 p.m.

Red alert means there is insufficient power supply and authorities may implement rotational brownouts in some areas.

Meanwhile, a yellow alert is raised from 9 a.m. to 1 p.m. and from 4 p.m. to 8 p.m. This means power reserves have dropped below the minimum 647 megawatts, but does not necessarily mean there will be power outages.

NGCP said the alerts were raised because of insufficient operating reserves due to the forced outage of multiple power plants.

A red alert status was hoisted over the grid for the first time this year on April 10 following consecutive days of being under yellow alert.

Energy officials have said that despite the insufficient power reserves over the past week, there is no power crisis. They also said they are open to an investigation into the matter.
