National Power Corporation (August 10, 1998 – March 1, 2003) National Transmission Corporation (March 1, 2003 – January 15, 2009) National Grid Corporation of the Philippines (January 15, 2009–present)
The transmission line is an triple-bundle power line and bipolar HVDC.
Capacity of the Leyte-Luzon is a 440 MW.[4][5][6][7] It is implemented as monopolar line for a voltage of 350 kV,[6] feeding the power grid in the Manila region. In addition to overall connection of grids, HVDC was chosen to enable supply of bulk geothermal power, and to stabilize the alternating current network in Manila region.[4][7] The interconnector was manufactured by the ABB Group in cooperation with Marubeni Corporation.[7]
The length of submarine cable is 21 kilometers (13 mi) and the total length of overhead lines is 430 kilometers (270 mi).[4][5][7]
The crossing of San Juanico Strait is realized as overhead crossing with a tower on an island in the strait.
By time in construction of the 1st tower ((8LI1NAG-ORMOC HVDC)0001) was erected and it is now commonly the first HVDC tower in the Philippines.
