SYSTEM OPERATOR National Grid Corporation of the Philippines (NGCP) has finished repairing a key substation that had been damaged in March and crippled the delivery of power to Metro Manila.
NGCP, which operates power grids and transmission systems, yesterday said it restored the Las Piñas-Zapote substation by installing a 300-megavolt ampere transformer to replace a damaged unit which had caused the firm to rely on contingency measures to sustain the grid’s integrity.
The substation is one of the six entry points of power into Metro Manila and the Manila Electric Co. (Meralco) franchise area.
It is part of Meralco’s subtransmission system that feeds power to Makati, Fort Bonifacio, Ortigas, Parañaque, Alabang, Cainta and Marikina.
“The Las Piñas transformer was energized ahead of schedule on April 29.
It was included again in the loop of substations that supply electricity to the South of Metro Manila by April 30,” the company said in a statement.
The damage to the Las Piñas substation had meant any surge in power supply or any other transmission problems could overload the system. — Emilia Narni J. David
