Energy Sector Press Oil & Gas Division Abu Dhabi, June 4, 2013 Siemens develops SST-500 GEO steam turbine for geothermal power plants Siemens Energy has developed a new steam turbine for geothermal power plants to serve the power range up to 120 megawatts (MW). The SST-500 GEO follows the SST-400 GEO turbine, which was introduced in the autumn of 2011. The SST-500 GEO is a single-casing, double-flow condensing turbine. As a derivative of the SST500 and SST-600 turbine families, it combines the proven casing and auxiliaries of the Siemens SST-500 and SST-600 steam turbines with the geothermal features and steam path technologies developed, tested and applied by Siemens Energy Services. The SST-500 GEO steam turbine can be deployed in geothermal power plants with a varying range of steam conditions, being designed for both single and double flash applications. Power generation from geothermal energy is a mature technology. In contrast to other popular renewable energy sources, geothermal energy can be used around the clock, regardless of the time of day or weather or climatic conditions, such as solar radiation, clouds and wind strength, enabling high availability base-load power plants to utilize this natural energy source in many parts of the world. At the end of 2012, the global installed power generating capacity of geothermal power plants was more than 11 gigawatts (GW), and further strong growth is expected. “With the SST-500 GEO we will expand our portfolio in the range of steam turbines for geothermal power plants,“ said Markus Tacke, CEO of the Industrial Power Business Unit of Siemens Energy. “We are now able to offer a family of turbines that is based on our unique know-how as a world leading manufacturer of industrial steam turbines as well as on our extensive experience in the geothermal aftermarket. The SST-500 GEO will enable us to participate in the geothermal growth we currently see in regions such as the eastern coast of Asia, the western coast of the Siemens AG Wittelsbacherplatz 2, 80333 Munich, Germany Corporate Communications and Government Affairs Head: Stephan Heimbach Reference number: EOG201306.037e Energy Sector Oil & Gas Division Sheikh Zayed 2nd Street, Abu Dhabi Page 1/3 Siemens AG Press Release Americas and parts of Africa.” The new turbine will also be introduced at the GeoPower Indonesia 2013 conference in Jakarta. Geothermal resources most often are found in areas with high seismic activity which must be considered in the turboset design. The turbines themselves frequently face highly corrosive steam which consumes conventional materials. Steam quality is low but with large volume flows. These challenging physical conditions require specially adapted steam turbines. “Siemens has been active world-wide in the geothermal after-markets for over 20 years,” states Werner Altmeyer, Siemens' sales manager responsible for the industrial turbine business. “During that time major refurbishments, including supply of new rotors, blade redesign and replacement of complete steam paths have been carried out on machines supplied by the major geothermal turbine manufacturers. For the design of the SST-500 GEO, we exploited that experience, along with our expertise as a leading industrial steam turbine manufacturer.” Each SST-500 GEO turbine is designed uniquely for particular resource conditions by adapting the blade path within the standardized casing. Like all Siemens geothermal turbines, the SST-500 GEO is designed with an impulse type steam path, which due to the robust design has been proven by extensive experience in the after-market. The materials of all steam path components are specifically selected according to the particular conditions and the specific steam chemistry of the application to resist corrosion and corrosion-related cracking. The SST-500 GEO is suitable for live steam temperatures up to 250°C, with steam pressures up to 15 bar absolute, and includes resource- and turbine-stage-specific high-grade materials as well as special features for moisture removal at every stage.

Turbin SST-500 GEO adalah pengembangan dari SST-400 GEO yang telah diluncurkan pada akhir tahun 2011, sekarang diperkenalkan di Indonesia pada ajang konferensi GeoPower Indonesia 2013 di Jakarta pada tanggal 18-19 Juni 2013. SST-500 GEO adalah condensing turbine dengan single-casing dan double flow, sebagai turunan dari kelompok turbin SST-500 dan SST-600 turbine ini merupakan kombinasi yang telah terbukti handal antara casing dan auxiliary dari turbin Siemens SST-500 dan SST-600 dengan mengembangkan fitur panasbumi dan teknologi jalur uap panasbumi serta telah diuji coba dan diterapkan oleh Divisi Energy Services Siemens. Turbin SST-500 GEO telah digunakan pada pembangkit listrik tenaga panasbumi dengan berbagai kondisi uap serta dirancang khusus untuk aplikasi single maupun double flash. Generasi pembangkit listrik dari tenaga panasbumi adalah teknologi yang sudah mapan. Berbeda dengan sumber-sumber energi terbarukan lainnya, energi panasbumi ini dapat digunakan sepanjang waktu, terlepas dari kondisi siang hari atau cuaca buruk seperti radiasi matahari maupun pada cuaca berawan dan berangin sehingga memiliki kemampuan tinggi untuk pembangkit listrik pada beban dasar dengan memanfaatkan sumber energi ini digunakan di berbagai belahan dunia. Pada akhir 2012, total daya listrik terpasang secara global yang menggunakan pembangkit listrik tenaga panasbumi telah mencapai lebih dari 11 gigawatt (GW) dan diperkirakan akan terus meningkat. “Dengan SST-500 GEO, kami ingin memperluas portofolio kami di sektor turbin uap khusus untuk pembangkit listrik tenaga panasbumi,” jelas Dr. Markus Tacke, CEO PT Siemens Indonesia Jakarta, Indonesia Communications Head: Julieta Glasmacher Reference number: ID CC PR 201306.18 i Page 1/2 Press Release dari Unit Bisnis Industrial Power, Siemens Energy. “Sekarang kami telah dapat menawarkan sebuah keluarga turbin yang berbasis pada teknologi yang unik sebagai produsen terkemuka di dunia untuk turbin uap industri serta mempunyai pengalaman luas di segmen pasar layanan purna jual turbin panasbumi. Dengan adanya SST-500 GEO, kami dapat ikut berpartisipasi dalam pasar panasbumi yang sedang bertumbuh pesat seperti di kawasan pantai timur Asia, pantai barat Amerika dan sebagian wilayah Afrika.” Setiap turbin SST-500 GEO dirancang secara unik untuk kondisi sumber daya tertentu dengan mengadaptasi jalur pisau (blade) dalam casing standar. Seperti semua turbin uap panasbumi dari Siemens, SST-500 GEO dirancang dengan impuls dan steam path khusus. Hal ini dibuktikan dengan pengalaman kami yang kuat di segmen pasar layanan purna jual turbin panasbumi. Semua materi dari komponen steam path dipilih secara khusus sesuai dengan kondisi tertentu dan diaplikasikan secara spesifik untuk menahan korosi yang terkait pada keretakan. SST-500 GEO cocok untuk suhu uap sampai dengan 250 derajat selsius dengan tekanan uap sampai dengan 15 bar absolute.
