THE National Grid Corp. of the Philippines (NGCP) has moved to accomodate the 130-megawatt peak load of Baguio City, Benguet and Mountain Province with the commissioning of a 300-megavolt ampere (MVA) and 50-MVA power transformers at its La Trinidad and Ambuklao Substations, respectively.
The energization of said power transformers is part of the Luzon Substation Expansion Project, which also includes substation equipment testing and upgrading of conductors and other associated equipment.
With the 50-MVA transformer at Ambuklao Substation, the Philippine Economic Zone Authority may now draw power from either the La Trinidad or Ambuklao Substation.
To comply with the Philippine Grid Code’s N-1 contingency requirement, which is the ability of the grid to withstand the loss of a major system component with minimal disruption, another 300-MVA transformer is expected to be commissioned at La Trinidad Substation this July 2015.
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, towers, substations and related assets.
The consortium, which holds the 25-year concession contract to operate the country’s power-transmission network, is comprised of Monte Oro Grid Resources Corp. led by Henry Sy Jr., Calaca High Power Corp. led by Robert Coyiuto Jr., and the State Grid Corp. of China as technical partner.
