THE Energy Regulatory Commission (ERC) issued the green light for the National Grid Corp. of the Philippines (NGCP) to undertake the P9.7-billion Taguig Extra High-Voltage (EHV) Substation project.

The substation project, which will be implemented this year, will serve as another drawdown substation to decongest the San Jose EHV Substation, and provide higher level of reliability to the Luzon Grid system.

“The approval of the NGCP’s EHV substation project will address the growing power demand and power import in Metro Manila. Additional capacities that will be injected into the transmission network by new power generators will soon be accommodated through this project, which will mean a sustainable and reliable supply of power,” ERC Chairman and CEO Agnes VST Devanadera said.

Apart from the decongestion of the San Jose EHV Substation, the Taguig EHV Substation will also ease the existing 230-kilovolt single-circuit line from Quezon to Muntinlupa during emergency situations, such as grid failure, and address the severe under voltage in the 230-kV substations within Metro Manila due to the single-circuit configuration and heavy loading condition of the Quezon-Doña Imelda-Paco-Muntinlupa 230-kV transmission line.

In addition, the Taguig EHV Substation will complement the plan of linking the new drawdown substation to Taytay 230-kV substation, as the project will make an additional 230-kV transmission line link to the said Taytay Substation.

ERC’s approval of the Taguig EHV Substation is anchored on the condition that the project is subject to optimization based on its actual use and/or implementation during the reset process for the next regulatory period, as stated in the Rules for Setting the Transmission Wheeling Rates and other relevant issuances of the ERC.

Optimization entails the removal of redundant assets and overcapacity, including inefficient design and engineering within the existing network.  NGCP is also required to conduct competitive bidding in the implementation of the proposed projects.
