Steam Turbines

GE Vernova’s steam turbines are a cornerstone of global power generation, combining over 120 years of engineering expertise with cutting-edge technology to deliver efficient, reliable, and flexible energy solutions. Powering more than 1,100 combined-cycle plants across 70+ countries and generating over 195 GW of electricity, these turbines are designed for rapid deployment, high availability, and long-term durability. With advanced features like high-reaction 3D blading, welded rotors, and integrally shrouded blades, GE Vernova turbines optimize steam flow and mechanical integrity across high-, intermediate-, and low-pressure modules1. Their integration with digital control systems and predictive maintenance tools ensures peak performance and reduced lifecycle costs, making them a trusted choice for fossil, nuclear, and industrial power applications worldwide.

Siemens Energy steam turbines are engineered to deliver high-efficiency, flexible power generation across a wide range of industrial and utility-scale applications. With outputs ranging from 10 kW to 1,900 MW, their portfolio includes compact industrial units, robust utility turbines, and specialized Dresser-Rand models for mechanical drives and cogeneration. Built on over a century of innovation, Siemens Energy turbines feature modular designs, rapid start-up capabilities, and advanced control systems that optimize performance and reduce emissions. With more than 8,000 units in service worldwide, these turbines are trusted for their reliability, adaptability to diverse fuel sources, and role in driving the global transition toward cleaner, more sustainable energy.

Siemens Energy hat eine neue Dampfturbine für Geothermie-Kraftwerke mit einer Leistung von bis zu 120 Megawatt (MW) entwickelt. Sie folgt auf die SST-400 GEO, die im Herbst 2011 eingeführt wurde. Die eingehäusige, zweiflutige Kondensationsturbine SST-500 GEO ist eine Weiterentwicklung der Dampfturbinenfamilien SST-500 und SST-600. Sie verbindet Bauteile des Gehäuses sowie der Hilfs- und Nebenanlagen der beiden bewährten Siemens-Turbinen. Darüber hinaus ist der von Siemens Energy Services speziell für geothermische Anwendungen konzipierte und erprobte Dampfströmungsweg in die Entwicklung der neuen Dampfturbine mit eingeflossen. Die SST-500 GEO kann zur Nutzung der Erdwärme bei verschiedenen Dampfbedingungen eingesetzt werden, da sie sowohl für Single-Flash- als auch für Double-Flash-Anwendungen konstruiert wurde. 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 SST-500 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.
