The National Grid Corporation of the Philippines (NGCP) is allotting P160 billion in capital expenditure (CAPEX) in its filing with the Energy Regulatory Commission (ERC) for the 5th Regulatory Period from 2021 until 2025.
P 111.4 billion of the total CAPEX is for transmission projects, including completed and ongoing projects, those in the pre-construction stage, and those still in the pipeline.
Included in the CAPEX filing, are transmission projects within and around Metro Manila such as the Pasay 230kV Substation; Manila (Navotas) 230kV Substation; Marilao Extra High Voltage Substation; New Antipolo 230kV Substation; Taguig Extra High Voltage Substation; Taguig-Taytay 230kV Transmission Line; and Taguig-Silang 500kV Transmission Line.
To meet the forecasted load growth in Metro Manila, NGCP will develop three major 500/230kV drawdown substations around Metro Manila. These will be in Taguig City; Marilao, Bulacan; and Silang, Cavite. These are to be complemented by the development of additional 230/115kV substations in Antipolo, Navotas, and Pasay.
The reliability of power transmission delivery to Metro Manila will be addressed through the development of new transmission corridors in Metro Manila such as the Taguig-Silang 500kV and Taguig-Taytay 230kV lines.
Island interconnection projects such as the Palawan-Mindoro and Batangas-Mindoro Interconnection which are in the pre-construction stages are also in the list.
The proposed interconnection of Mindoro Island with the Luzon Grid was envisioned to provide access to bulk generation sources in the main grid, while at the same time providing the means to export possible excess power within the island.
The nearest connection point in the Luzon Grid for the planned island interconnection project is the proposed Pinamucan 500kV Substation in Batangas, while Calapan would serve as the interconnection point in Mindoro. In parallel, the interconnection of Palawan to Mindoro is already being studied to provide more reliable power supply to the island province.
“NGCP continues to invest in undertakings for the improvement of the power transmission grid. We are also working on applying smart grid technologies to ensure reliable, efficient, and safe operations and create a world-class transmission network,” said NGCP.
Operations and Maintenance, a major responsibility of NGCP, also has a CAPEX allotment totaling P22.3 billion for the 5th Regulatory Period. It will focus on substation and transmission line reliability projects, upgrading of O&M tools and equipment, and network facility improvement with the introduction of smart grid technology.
CAPEX for System Operations projects in the 5th Regulatory Period amounts to P7.1 billion. This amount is allotted for upgrading of the SCADA/EMS system, expansion of grid-related telecommunications facilities, further enhancements of cybersecurity systems, and power quality monitoring.
Investments on infrastructure development for NGCP’s IT network, security, aviation, and facilities are also included in the CAPEX proposal to the ERC. (ngcp/ The Sun Monitor)
