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.
