Motivation to develop a new standardized CCPP:
• New available gas turbine H-80 with radial exhaust (Hot-End-Drive) within the Hitachi Power Segment
• Lack of available Combined Cycle Power Plants in th e 150 MW-class with 1 GT resp. 300 MW -class with 2 GT
Requirements to the new CCPP-Concepts:
• Compact and less consuming area demand plant design
• Optimized for decentralized combined production of distri ctheat and-/or process steam extraction and electricity
• Optimal economic efficiency for both power- and heatoriented operation ���� plant concept without reheat!
