In an advisory, Manila Electric Co. (Meralco) said the system condition for the line system for Monday is red. "The National Grid Corporation of the Philippines (NGCP) advised that there will be a rotational brownout today, Monday, March 1, between 10 a.m. and 10 p.m. due to a boiler tube leak of Sual 1 and Masinloc," the advisory said.

Meralco spokesman Joe Zaldariagga said some of the areas experiencing power outages as of 12 p.m. are parts of Alfonso and Bacoor in Cavite and Tagaytay City. He said Meralco has yet to receive word from the NGCP that the power shortfall will be addressed.

"We are hoping that there will be some improvement but being a distribution utility, we are not in a position to determine what the power supply will be tomorrow. We rely on the announcement of the system operator, which is the NGCP," he told ANC's Dateline Philipines.

A separate NGCP advisory said the Luzon grid now has a generation deficiency of 478 megawatts.

"Metro Manila and Luzon residents are advised to coordinate directly with their respective distribution utilities and electric cooperatives for information on the power interruption schedule and list of specific areas which will experience temporary power outage," the NGCP said.

The NGCP said the Visayas grid has a generation deficiency of 45 megawatts. "Salcon Power's Cebu Thermal Power Plant Unit 1 is operational and already loaded with 48 MW but Unit 2 with a rated capacity of 55 MW is under preventive maintenance shutdown. Estimated completion date of maintenance works is on March 7,' it said.

The NGCP said Mindanao wil continue to experience rotating blackouts after the El Niño phenomenon affected the output of hydro power plants.
