MANILA – The National Grid Corp. of the Philippines has announced plans to increase the capacity of its substations in Batangas and Laguna in preparation for the increasing requirement of bulk power customers in the South Luzon area.
The project is part of the P515-million included in the Luzon Substation Expansion III. Started in December 2011, the project is scheduled to be completed in the first quarter of 2013. Two units of 300-megavolt ampere transformers will replace the two existing 100-MVA transformers in the Batangas substation. One unit of a 100-MVA transformer will also be installed at the Bay substation.
The capacity expansion is required to maintain the provision of N-1 contingency as the majority of the connected customers in the involved substations are expected to grow by more than 2 percent in the next five years.
The N-1 contingency enables the power grid to sustain its integrity in case of loss of a major component of the system. Data from NGCP's Planning and Engineering Group indicate growth rates of its big customers including Atlantic Gulf & Pacific Company (3.91 percent), Bobcock-Hitachi (3.09 percent), San Miguel Foods Inc. (3.78 percent), and Puyat Steel Corporation (2.33percent).
Other customers are Keppel Philippine Shipyard (2.49percent), Ibaan Electric & Engineering Corporation (3.53percent), BATELEC 2 (2.61percent), Lima Land (3.41percent), Philtown (3.51percent), Republic Cement (3.26percent), and Coco Chemical Industries (2.48percent).
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.*PNA
