Presented at World Bank GeoFund – IGA Geothermal Workshop 2009


The Germencik 45 MW geothermal power station – a large new power station near Izmir – is the newest addition to Turkey´s renewable energy landscape. The plant is now being completed by the Turkish company Güris and will be operated by its subsidiary Gürmat. Power plant design was performed by POWER Engineers, Inc. of the USA. The chemical characteristics and energy content of geothermal resources varies widely from place to place, so design of the Germencik plant – as with geothermal plants everywhere – was customized to the resource found there. Specifically, the plant incorporated features and new technology in the steamfield, condenser, and gas removal systems directly tailored to improve efficiency, economy, and operational flexibility. Commissioning of the Germencik plant is expected in early 2009 and additional details on actual performance will be the topic of future reports. The purpose of this paper is to describe the design approach and options considered for key plant aspects such as cycle selection, scaling reduction, and condenser/gas removal equipment.
