Outline of Mahanagdong Geothermal Power Project

Abstract

Introduced here is the Mahanagdong Geothermal Power Project (3 x 60MW) in Leyte island of the Philippines which is one of the latest geothermal project and consists of Toshibaís three sets of steam turbine, generator and its auxiliaries. The Mahanagdong Geothermal Power Project started in 1993 as a contract between PNOC-EDC (Philippine National Oil Company-Energy Development Corporation) and CECI (California Energy Company Inc.), and Toshiba joined to this project in 1994 as a turbine and generator supplier. The special feature of this project is that this is the first BOT (Built, Operate & Transfer) contract for the geothermal power project in the world. The construction period of the project up to start of commercial operation for 3 units was 32.5 months, while the turbine and generator of the first unit was CIF in 16 months. The Mahanagdong Geothermal Power Plant (containing three 60MW turbine & generator sets, total 180MW rated output plant) consists of two sites, i.e. Site A (2 x 60MW) and Site B (1 x 60MW). This plant had achieved its rated output successfully in August 1997 at first, and now, electricity produced are mainly supplied to Luzon island and Cebu island via submarine cable.
