The National Grid Corp of the Philippines (NGCP) has upgraded its substation in Benguet Province to improve its transmission systems in the area as part of measures to ensure stable power supply amid the ongoing hot summer season.
NGCP said in a statement it has commissioned a 300-megavolt ampere (MVA) and 50-MVA power transformers at its La Trinidad and Ambuklao substations in Benguet.
Government energy officials last year warned that the country faced a serious power shortage this summer and urged Congress to grant President Benigno Aquino 3rd emergency powers to deal with the feared crisis.
But Congress sat on the proposal and so far, the feared rotating daily brownouts have not materialized.
The 300-MVA transformer at the La Trinidad substation, which was energized last March, would accommodate the 130-megawatts (MW) peak load of Baguio City, the entire Benguet and Mt. Province, and parts of Ilocos Sur and Kalinga, NGCP said.
It said another 300-MVA transformer will be commissioned at La Trinidad Substation in July to comply with the Philippine Grid Code’s N-1 contingency requirement.
Code N-1 is the ability of the grid to withstand the loss of a major system component with minimal disruption.
With the 50-MVA transformer at Ambuklao substation, the Philippine Economic Zone Authority (PEZA) could now draw power from either the La Trinidad or Ambuklao substation.
The energization of power transformers is part of the Luzon Substation Expansion Project, which also includes substation equipment testing and upgrading of conductors and other associated equipment.
NGCP is a private 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.
