The link transfers power from a geothermal power plant on the island of Leyte to the southern part of the main island of Luzon
Leyte-Luzon is a 440 MW, 350 kV monopolar HVDC link in the Philippines. It transfers power from a geothermal power plant on the island of Leyte to the southern part of the main island of Luzon, feeding the existing AC grid in the Manila region. The transmission is owned by the Philippine utility, National Transmission Corporation (TransCo).
A contract comprising design, delivery, installation and commissioning of the converter stations as well as electrode and cable stations was awarded in 1994 to Hitachi Energy in cooperation with Marubeni Corporation, Japan.
The HVDC interconnection is beneficial both to industry and inhabitants of the Manila area, not only through the added power influx, but also because of the inherent stabilizing effect of an HVDC link on the AC network.
Heat from the earth that warms water trapped in underground rock formations can be used to drive steam turbines, and the geothermal resources on Leyte have the potential to provide low cost, reliable and much-needed energy to meet growing power requirements in the Philippines. Geothermal power contributes significantly to environmental improvements on both the national and global scale.
