The National Grid Corporation of the Philippines (NGCP) will begin anytime this year its application to the Energy Regulatory Commission (ERC) for the P56-billion power interconnection project which will connect Visayas and Mindanao grids through the Cebu-Dipolog route.
The interconnection project, which has a target completion in 2020, is a long-time request by power producers especially in Mindanao to allow them share or sell power surplus. At present, only Luzon and Visayas Grid are interconnected.
NGCP Head of the Mindanao System Planning Fernando Javier bared the application will be part of the NGCP’s overall implementation of the transmission development projects in Mindanao.
Javier said the submarine cable would run about 55 kilometers with a capacity of 450 megawatts in both ways.
Javier, who presented the Mindanao System Plan during Tuesday’s Power Forum on NGCP Projects, said the power interconnection project is being pushed after the result of the NGCP-commissioned hydrographic survey conducted from September to November last year.
Javier said the Cebu-Dipolog is the most viable route along the country’s western seaboard for interconnecting the Visayas and Mindanao grids.
Javier said, NGCP already dropped the eastern route because it is not suitable due to significant presence of live ordnance.
Earlier, NGCP bared that previous feasibility studies showed the eastern routes as unsuitable for submarine cable ground laying because of a significant quantity of live ordinance – torpedoes and high explosive shells – from the Battle of Surigao in 1944, an underwater volcano, fault lines, and seismic hazards, such as unstable rock slabs that can cause landslips and tsunamis.
NGCP has sought the support of the public and its stakeholders for the full and immediate implementation of the project and assured of NGCP’s dedication to determine the most reliable and cost-efficient path to completion.
“This is a large undertaking. We want this facility to be state-of-the-art, as well as sturdy enough to last generations. We are considering many factors in the design and implementation of the project, including changing weather conditions. Ensuring the quality and reliability of power transmission services to both Visayas and Mindanao customers is of paramount importance,” NGCP said.
NGCP announced it will proceed with the preparation of a conceptual design, detailed cost-estimate, and update of system simulation study. They will also include inland and route surveys for substations and associated overhead transmission lines. Ayan C. Mellejor
