The red alert status is in effect from 3 p.m. to 8 p.m. while the yellow alert status is in effect from 8 p.m. to 9 p.m.
NGCP said a red alert status is issued when power supply is insufficient to meet consumer demand and the transmission grid’s regulating requirement.
A yellow alert is issued when the operating margin is insufficient to meet the transmission grid’s contingency requirement.
The factors that contributed to the red and yellow alert status are the following:

- Unavailable import from Luzon
- High System Demand
