The country’s power grid operator, National Grid Corporation of the Philippines (NGCP), is seeking regulatory approval for a new substation in Laguna that will require a P833-million investment.
In a statement, NGCP said that it is in the stage of seeking the approval of the Energy Regulatory Commission (ERC) to start construction of a new substation in Calamba City, Laguna.
The project aims to serve the Laguna sector of the Manila Electric Co. (Meralco) and will entail construction of a new 230-kilovolt (kV) substation and transmission line extension from the existing Biñan-Bay (Makban) 230-kV line.
With a proposed capacity of 600 megavolt amperes (MVA), the Calamba Substation is seen to serve the long-term requirement of the loads from industrial parks in Laguna and Batangas.
Once approved, the project, with an estimated cost of P833 million, is targeted for completion by the first quarter of 2016.
Considered as NGCP’s largest customer, Meralco’s Laguna sector is currently drawing electricity from three 230/115kV substations—Biñan, Malamig (Santa Rosa), and the Calauan substations.
According to the NGCP, the addition of the Calamba Substation will ease the loads of the Malamig and Calauan substations during outages, thereby securing the transmission of electricity in Laguna.
“Once energized, the Calamba Substation will be strategically located midway of Santa Rosa and Calauan Substations. NGCP aims to address the required N-1 contingency that will support the bulk of the load in the area,” NGCP spokesman Cynthia Perez-Alabanza said.
“Apart from expansion of the grid, NGCP focuses on the reliability of the system by ensuring minimal disruptions. Every system will suffer a glitch once in a while. N-1 will ensure that our customers won’t feel those glitches if the redundancies are in place,” she added.
N-1 contingency refers to a Philippine Grid Code requirement, which is the ability of the grid to withstand the loss of a major system component with minimal disruption in the system.
The project will address the N-1 contingency requirement of the Malamig and Calauan Substation, and the Calauan-Los Baños 115-kV distribution line.
