National Grid Corp of Philippines start work on the Compostela substation expansion project

The National Grid Corporation of the Philippines (NGCP) is undertaking the Compostela Substation Expansion Project in Cebu. This is to keep up with the rapid growth of power demand in Visayas, said Elmer Cruz, NGCP Visayas Corporate Communications and Public Affairs Officer.

A 150-megavolt ampere (MVA) transformer, power circuit breakers, and accessories will be installed at the Compostela substation.

The expansion project is pegged to cost P221.15 million and is expected to be completed by the end of May 2013, said Cruz.

The increase in substation capacity is seen to stabilize the Leyte-Cebu 230-kilovolt Interconnection System linked to the Visayas Transmission Backbone.

Bulk of the power transmitted from the Leyte Geothermal Plants, pass through the Compostela Substation and are then delivered to the Cebu, Negros, and Panay sub-grids.

All major islands in Visayas are connected to the power grid, with Cebu recording the highest power consumption. The highest recorded power demand in Cebu during peak periods  is at 680 MgW.

NGCP is a privately-owned corporation in charge of operating, maintaining, and developing the country’s power grid by transmitting electricity through “power superhighways” which include the interconnected system of transmission lines and towers, substations, and related assets
