Ayalas seek ERC OK to connect Zambales solar plant to the Luzon grid

Ayala-led AC Energy subsidiary Santa Cruz Solar Energy Inc. (SCSEI) has filed an application with the Energy Regulatory Commission to connect its planned 280 megawatt solar facility to the Luzon grid.

The company plans to put up an temporary connection estimated to cost P1.644 billion using the 500 kV Heromasa-Castillejos line while the 230 kV Castillejos substation has yet to be completed.

Once the 230 kV Castillejos substation is constructed, it will develop a dedicated point-to-point facility to connect its solar plant to the Luzon grid.

SCSEI had planned a total of 500 MW solar project of which the first phase (280 MW) will be operational next year and the remaining 220 MW by 2024.

“The interim connection facility will ensure the earliest possible injection of capacity from the San Marcelino solar power plant project to the Luzon grid, thus enhancing the Luzon’s grid’s stability and reliability, without waiting energization of NGCP’s 230 kV Castillejos substation,” the company said in its application.

Once completed, the solar project will add to the growing renewable energy portfolio of Ayala-owned AC Energy.
