Toshiba Corporation and Ormat Technologies Inc. yesterday announced that the first unit of the Sarulla geothermal power plant, one of the world's largest power plants, located in Indonesia's North Sumatra, has commenced commercial operation.

The approximately 110 MW power plant, which combines flash and binary technologies to provide a high efficiency power plant and 100% reinjection of the exploited geothermal fluid, is operated by Sarulla Operations Ltd. (SOL). As participants in the project, Toshiba supplied the geothermal steam turbines and generators (STGs) for the flash systems, while Ormat provided the conceptual design of the Geothermal Combined Cycle Unit (GCCU) power plant and supplied its Ormat Energy Converter (OEC), which serve as the condensing units for the steam turbines and utilize the separated brine for maximum resource exploitation and maximum power output.
