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 2x1 Flex-Plant™ 30
- Description
- Benefits
Using integrated fast-start technology, the 618 MW SCC6-5000F 2x1 Flex-Plant™ 30 can achieve full load in about half the time required by traditional combined cycle plants, while retaining its high 57%+ net efficiency with a triple-pressure reheat bottoming cycle. The optimized steam turbine start package offers the fastest startup time of any combined cycle plant. In addition, the gas turbines in the SCC6-5000F 2x1 Flex-Plant™ 30 are quickly ramped to emissions-compliant load resulting in more dispatchable power, more quickly with significantly reduced startup emissions and startup fuel costs.
