NATIONAL Grid Corp. of the Philippines (NGCP) said on Monday that it is building a P17.9-billion transmission corridor through its western Luzon 500-kilovolt (kV) backbone in response to the expected load growth in the area.
In a statement, the privately-owned grid operator said it was working on the project ahead of the “bulk generation” expected out of Zambales, including a two-unit coal-fired power plant of Redondo Peninsula Energy, Inc. each with a capacity of 300 megawatt (MW).
“All of these projects in the western part of Luzon are critical in the stability and reliability of the transmission system in the near future,” NGCP said.
“Of course, the support and help of our stakeholders are still crucial in the smooth implementation and on-time completion of these projects,” it added.
It said the first stage of the project will involve the construction of the Castillejos-Hermosa 500-kV transmission line and will be connected to the new Hermosa substation. The P1.34-billion project, which had been approved by the Energy Regulatory Commission (ERC) is expected to be completed by the second quarter of 2020.
The second stage will involve the construction of a new Castillejos substation, Bolo substation, and the Castillejos-Bolo 500-kV transmission line. This stage is expected to be finished by 2025.
NGCP said it was also working on other projects in Bataan — the Mariveles-Hermosa 500-kV transmission line, the Hermosa-San Jose 500-kV transmission line, and the Hermosa-Floridablanca 69-kV transmission line.
It said the Mariveles-Hermosa 500-kV transmission line will serve as a new transmission corridor for around 2,836 MW from power plants such as the projects of GNPower Dinginin Ltd. Co. and SMC Consolidated Power Corp.
The project entails the construction of a new Mariveles substation, along with the transmission line, said NGCP, which is in charge of operating, maintaining, and developing the country’s power grid.
The Hermosa-San Jose 500-kV transmission line project is being constructed as a new transmission corridor, which will cater to existing power plants such those in Limay and Subic, and generation capacity additions such as those from RP Energy and SMC Consolidated.
The Hermosa-Floridablanca 69-kV transmission line, which has an ERC-approved cost of P315.77 million and was energized in February, was constructed to support the old Hermosa-Guagua 69-kV line. It will address the low voltage concerns in the area.
The Mariveles-Hermosa 500-kV transmission line project will cost P5.94 billion, while the Hermosa-San Jose 500-kV transmission line project will cost P10.28 billion. Both will be completed in the fourth quarter of 2020.
The western Luzon 500-kV backbone, Mariveles-Hermosa 500-kV transmission line, Hermosa-San Jose 500-kV transmission line, and Hermosa-Floridablanca 69-kV transmission line projects were certified by the Energy Investment Coordinating Council as energy projects of national significance in January. — Victor V.
