The HVDC Leyte–Luzon is a high voltage direct current transmission link in the Philippines between geothermal power plants on the island of Leyte and the southern part of island of Luzon. The HVDC Leyte – Luzon went in service on 10 August 1998.
The HVDC Leyte – Luzon begins at Ormoc converter station (Leyte Province) and ends at Naga converter station (Province of Camarines Sur). It consists three sections:
- Leyte-Samar overhead line
- submarine cables across San Bernardino Strait between Cabacungan (Allen, Samar) and Sta Magdalena (Sorsogon Province, Luzon)
- overhead line at Luzon
The length of submarine cable is 21 kilometres (13 mi) and the total length of overhead lines is 430 kilometres (270 mi). The HVDC Leyte – Luzon can transfer an output of 440 MW. It is implemented as monopolar line for a voltage of 350 kV.
The crossing of San Juanico Strait is realized as overhead crossing with a tower on an island in the strait.
Aim of the HVDC link is to feed the AC grid in the Manila region. Beside of overall connection of grids, the HVDC Leyte – Luzon stabilize the AC network. The interconnector is manufactured by the ABB Group in cooperation with Marubeni Corporation and it's operated by state owned National Transmission Corporation.
The grounding electrodes are situated at Albuera at 10°54′01″N 124°42′24″E / 10.90028°N 124.70667°E and near Calabanga at 13°43′59″N 123°14′29″E / 13.73306°N 123.24139°E . They are connected with the converter stations by 25 respecitively 15 kilometres long overhead lines.
