MANILA -- Several areas in Luzon could be hit with rotational brownouts for up to 3 hours with the country's main island on the highest power supply alert on Friday due to insufficient capacity, authorities said.

The affected areas, according to Meralco, include portions of the following areas: Quezon City, Caloocan City, Parañaque City, Pasay City, San Juan City, Las Piñas City, Valenzuela City, Malabon City, Navotas, Pasig City, Taguig City, Taytay, Cainta, Batangas City, Talisay, Plaridel, Malolos City, San Rafael, San Ildefonso, Pandi, Norzagaray, Doña Remedios Trinidad, Angat, Paombong, Hagonoy, Calumpit, Meycauayan, Santa Maria, Marilao, Bocaue, Imus, General Trias, Dasmariñas, Trece Martires City, Tagaytay City, Silang, Naic, Indang, Amadeo, Bacoor, Noveleta, Kawit, Cavite City, Tanza and Cabuyao.

"We are adjusting to the current situation... Ngayon, negative na. Ibig sabihin wala na tayong mapapagkunang reserba. In this case, deficiency na tayo," Meralco spokesman Joe Zaldarriaga said.

(We are adjusting to the current situation... Now, it's negative. This means there are no sources for reserves. In this case, there's a deficiency.)

Asked if more rotational brownouts are forthcoming, Zaldarriaga said Meralco would handle the situation "a day at a time."

The situation on Saturday and Sunday could be "better" with power demand expected to fall by 15 to 20 percent compared to weekdays, he said.


A red alert was raised in Luzon with demand expected to peak at 10,334 megawatts, higher than available capacity of 10,220 megawatts, National Grid Corp said.

The Luzon grid has been on red alert on and off this week, triggering rotational brownouts of 1 to 2 hours in some areas.

The red alert will be in effect from 9 a.m. to 10 p.m., a 13-hour stretch. The second highest warning, yellow, was in effect from 8 a.m. to 9 a.m. and again from 10 p.m. to 11 p.m., the NGCP said.

Meralco, the country's largest power distributor that operates in Luzon, said commercial establishments were ready to switch to generators to ease demand on the grid.

It advised the public to help conserve power by avoiding opening refrigerator doors unnecessarily, unplugging appliances when not in use and cleaning electric fan blades and aircon vents.
