NGCP seeks approval for P3.1-billion Antipolo substation

The Henry Sy-led National Grid Corp. of the Philippines (NGCP) is seeking the approval of the Energy Regulatory Commission (ERC) for plans to develop a substation in Antipolo City, which has a project cost of P3.1 billion.

In an application recently filed with the ERC, NGCP is currently waiting for the commission’s approval to build a new substation in Barangay San Juan in Antipolo City, Rizal province.

The Antipolo Extra High Voltage (EHV) substation project, which is expected to be completed in 2016, is part of NGCP’s 2012 Transmission Development Plan (TDP), a comprehensive strategy to expand and improve the Philippine grid in the next 10 years.

“With the establishment of Antipolo EHV substation, we can divert some of the load from San Jose substation thereby lowering its criticality level and vulnerability. It will give us operational flexibility that will allow us to maintain or shutdown the San Jose substation without affecting power delivery to and from Metro Manila,” lawyer Cynthia Alabanza, NGCP spokesperson, said.

According to the country’s power grid developer, the proposed Antipolo substation will be an EHV substation with an initial installed capacity of two 750-megavolt ampere (MVA) transformers, expandable up to four 750 MVA transformers.

The substation is further expected to prevent potential system congestion and relieve the San Jose substation in Bulacan, which carries the bulk of Metro Manila’s electricity load.

NGCP explained that the San Jose substation is the merging point of generation supply coming from the Masinloc and Sual Coal-Fired Power Plants (CFPPs) from the north, and Quezon Power Plant and Pagbilao CFPP from the south.

The project has two components—transmission line and substation. The transmission line component involves the construction of two 500-kilovolt (kV) transmission line extensions with a combined span of 17.5 kilometers connecting the Antipolo substation with San Jose and Tabayas EHV transmission lines.

The substation component of the project has two stages—the construction of the 230-kV switching facility beside the 115-kV substation in Antipolo of the Manila Electric Co. and the development of the EHV substation.

The first stage has been approved for implementation by the ERC.
