HVDC Leyte–Luzon is a high-voltage direct current transmission link in the Philippines between geothermal power plants on the islands of Leyte and Luzon.

History[]

The feasibility study of the transmission project was conducted by the Japan International Cooperation Agency in 1981.^[1] The project financing was approved by World Bank in June 1994, co-financed also by the Japan Export-Import Bank.^[2] The HVDC Leyte–Luzon went in service on August 10, 1998.^[3]^[4] It is operated by the privately-owned National Grid Corporation of the Philippines (NGCP) since January 15, 2009, and previously by government-owned companies National Transmission Corporation (TransCo) and National Power Corporation (NAPOCOR). It was owned previously by NAPOCOR from August 10, 1998 to March 1, 2003 and is owned currently by TransCo since March 1, 2003.

Technical description[]

Capacity of the Leyte-Luzon is a 440 MW.^[3]^[4]^[5]^[6] It is implemented as monopolar line for a voltage of 350 kV,^[5] 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.^[3]^[6] The interconnector was manufactured by the ABB Group in cooperation with Marubeni Corporation.^[6]

The length of submarine cable is 21 kilometers (13 mi) and the total length of overhead lines is 430 kilometers (270 mi).^[3]^[4]^[6]

The crossing of San Juanico Strait is realized as overhead crossing with a tower on an island in the strait.

Route[]

The HVDC Leyte–Luzon begins at Ormoc converter station (Leyte) and ends at Naga converter station (Camarines Sur).^[4] It consists three sections:

Leyte-Samar overhead line
submarine cables across San Bernardino Strait between Cabacungan (Allen, Samar) and Santa Magdalena (Sorsogon, Luzon)
overhead line at Luzon

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 respectively 15 kilometre-long overhead lines.
