Combined Cycle Power Plants
General Information
- Description
- Benefits
As in simple cycle applications the gas turbine is the main drive for power generation. To improve overall efficiency, exhaust heat from the gas turbine is used to produce steam for the generation of additional electricity by a steam turbine.
Reference Power Plants for Combined Cycle Application
Our Siemens combined cycle (SCC®) reference power plants (RPP) provide flexibility for easy selection of options to meet specific site and customer needs. This, together with a pre-designed balance of plant, results in short project lead times. It provides an optimum balance between capital cost, plant performance, and operational and maintenance considerations. Pre-engineered modular options have been developed to further address individual needs, as well as life-cycle cost enhancements.
- High efficiency
- Superior reliability and availability
- Low life-cycle costs
- Optimized profitability
- Rapid implementation
- Environmental compatibility

Power Plant SCC6-5000F 1x1 Flex-Plant™ 30
- Description
- Benefits
The SCC6-5000F 1x1 Flex-Plant™ 30 is a highly efficient combined cycle plant designed for intermediate to continuous duty, which is capable of daily cycling at efficiencies exceeding 57%. Using a Siemens SGT6-5000F gas turbine as the prime mover, the plant will provide high power density while requiring a relatively small plant footprint. A Siemens SPPA-T3000 power plant automation control system will provide an easy-to-use control platform for the entire combined cycle power plant. Additionally, a Siemens steam turbine SST-900 and a heat recovery steam generator (HRSG) with a Benson high-pressure (HP) evaporator, contribute to fast startup times which subsequently reduce emissions.
