NGCP partners with GE on 500kV transmission line and substation

The National Grid Corporation of the Philippines (NGCP) has tapped US-based conglomerate General Electric Co. (GE) for the development of a new transmission line and substation in Hermosa, Bataan, a crucial component in accommodating new generation capacity in the area.

In a statement, GE Power said its grid solutions business will be supplying auto transformers and power shunt reactors for the Hermosa project that will serve as a merging point of power, with an aggregate dependable capacity of about 4,000 megawatts.

GE Power’s Grid Solutions business will be supplying 2 banks of 1000MVA composed of 7 x 333.33 MVA, 1-phase, 60 Hz, 500/230-13.8 kV Auto-Transformers; 2 banks of 60MVAr (Bay reactor) composed of 6 x 20Mvar, 6 x 20 MVAR, 1-phase, 60 Hz, 500 kV Power Shunt Reactors; 1 bank of 90MVAr (Line reactor) composed of 3 x 30 MVAR, 1-phase, 60 Hz, 500 kV Power Shunt Reactors. The suite of solutions utilizes the latest in design, measurement and testing tools featuring optimized transformer cooling, low air forced cooler noise, advanced core design techniques that reduce no-load loss and no-load noise, and accurate design verification tools. It also includes a design software to perform advanced transformer analytics to help predict major breakdowns and minimize downtimes.

The development of a new 500 kV transmission backbone will serve as the additional outgoing circuits from Hermosa to San Jose to allow simultaneous maximum dispatch of existing power plants.

NGCP’s existing San Jose 500 kV Gas Insulated Switchgear Substation is currently the only connection point from power plants in North Luzon to its delivery points in Metro Manila down to South Luzon.

“The Hermosa substation project is in line with the Department of Energy’s strategic directions 2017-2040, which is to expand energy access to ensure affordable, reliable, sustainable, and modern energy supply for all,” the operator of the country’s electricity superhighway, was quoted in the statement as saying.

The project is expected to be completed in the fourth quarter of 2018.
