MANILA, Philippines—The power supply in Metro Manila and Rizal province is expected to return to normal as soon as the National Grid Corporation of the Philippines (NGCP) completes repairs on a third transformer at its Dolores substation in Taytay, Rizal.
The NGCP has restored two of the substation’s four transformers, each capable of delivering up to 150 megawatts to power distributor Manila Electric Co. (Meralco).
Both transformers now carry power from NGCP’s San Jose-Dolores and Malaya-Dolores 230-kilovolt lines to Meralco’s 115-kV lines. To balance the demand and supply of electricity in Metro Manila, part of the load of the Dolores substation has been shifted to the Zapote, Balintawak and Araneta substations.
NGCP, operator of the country’s so-called electricity superhighway, said the repair of two of the four 300-megavolt ampere transformers in the Dolores substation could ease the blackouts Metro Manila residents had been experiencing since Wednesday night.
With a forecast demand of 6,020 MW and available generation capacity of 7,640 MW in the Luzon grid, there were no brownouts expected Monday in Metro Manila.
Some areas of Metro Manila and Rizal were hit by power failure just before 9 p.m. Wednesday last week after one of the transformers in the Dolores substation caught fire. Amy R. Remo
