NGCP allocates Php 269-M to improve voltage in Luzon

PILI, CAMARINES SUR, September 27 – To improve voltage and boost system reliability the Luzon grid, the National Grid Corporation of the Philippines (NGCP) has invested Php 269 million pesos on additional capacitor banks at the high-voltage buses of various substations. 

The equipment is expected to benefit not only the substation supporting the installation, but the neighboring substations as well. 

The project also involves installation of shunt reactors in Naga substation and capacitor banks in four substations, namely Dona Imelda, Cabanatuan, Marilao and Muntinlupa. 

The shunt reactor in Naga aims to address the overvoltage problem experienced in the area during off- peak load condition with Tiwi plant at minimum generation. The reactors are also expected to address overvoltage during the switching of the filters of Leyte-Luzon High Voltage Direct Current (HVDC) Station in Naga City. 

The Leyte-Luzon HVDC Transmission System commissioned in August 1998 was part of the overall plan of the National Power Corporation (NPC) to connect the existing Luzon, Visayas and Mindanao grid into a single national grid. 

The capacitor components of the voltage improvement project in the four substations will improve the voltage profile during normal conditions and address the potential undervoltage during contingencies. 

The multi-million peso-project initiated in December 2011 is scheduled to be completed on the first quarter of 2013. 

NGCP is a privately owned corporation in charge of operating, maintaining, and developing the country’s power grid. It transmits high-voltage electricity through “power superhighways” that include the interconnected system of transmission lines and towers, substations and related assets. NGCP’s regular maintenance activities and expansion projects aim to enhance the reliability and quality of electricity delivered to customers. (Nelson Bautista, NCGP/PIA Sorsogon)
