In an advisory, the DOE said Luzon Grid would be placed under yellow alert on the following hours: 9:01 a.m to 1 p.m., 4:01 p.m. to 5 p.m., and 6:01 p.m. to 8 p.m.
It will be placed under red alert from 1:01 p.m. to 4:00 p.m., the DOE added.
According to DOE, the yellow and red alerts have been caused by insufficient operating reserves due to the forced outage of multiple power plants.
It also noted that several power plants are running at "derated capacities."
The National Grid Corporation of the Philippines said the Luzon Grid has an available capacity of 10,669 MW against a peak demand of 10,619 MW.
Luzon grid on yellow alert from 9:00AM-1:00PM, 4:00PM-5:00PM, and 6:00PM-8:00PM, and red alert from 1:00PM-4:00PM, 15 April 2019.— NGCP (@NGCP_ALERT) April 14, 2019
Available Capacity – 10,669MW
Peak Demand – 10,619MW
Details on the cause to be announced by the Department of Energy (DOE) later in the day.
Yellow alert is a condition in which the reserves are less than the capacity of the biggest plant online, which is 647 megawatts for Luzon, while the red alert is a system condition in which there is zero ancillary services or a generation deficiency exists.
In an interview on Dobol B sa News TV, Meralco spokesman Joe Zaldarriaga said they are still determining if they will cut power supply in some areas.
"Obviously, magpre-prepare din kami ng schedule pero as to whether or not we will actually interrupt some areas, 'yun 'yung titingnan pa natin," Zaldarriaga said.
"In the meantime, we're still encouraging 'yung consumers natin to practice energy efficiency," he added. —Anna Felicia Bajo/KBK, GMA News
