Siemens Steam Turbine-Generator SST-3000 Seriesfor combined cycle and steam power plant applications
SST-3000 series steam turbine-generator: References
With almost 8,000 steam turbine units in operation the Siemens fleet contributes nearly 540 GW of power generation capacity, representing 21% of the world’s operating fleet.
The following references show examples for combined cycle power plant applications.

SST-3000 series steam turbine-generator
For combined cycle and steam power plant applicationsIn our Siemens Steam Turbine (SST™) portfolio, we offer with the SST-3000 series steam turbine-generator a compact arrangement, that utilizes a two-cylinder design and axial exhaust applicable for combined cycle with the latest gas turbine technology or in conventional steam plants.
Turbine modules of different sizes provide a broad range of power ratings. To meet specific project requirements, Siemens selects the appropriate modules and custom engineers the individual blade path.
Proven pre-engineered modules reduce site assembly and commissioning times and reduce technical risk. High reliability and availability is demonstrated in a forced outage rate that is less than half of the North American Reliability Council (NERC) average.
