Conclusions
Key to success of pre-defined RPP concept cost efficient designproviding a reliable base for planning
The ultra-supercritical technology and the Siemens Reference Power
Plant SPP5-6000 fit the needs of the Indian market
High overall plant efficiencies, low emissions, proven components
Operational flexibility, grid support, ease of maintenance, reliablepower generation, minimising use of energy resources
The RPP concept allows for implementation of Indian engineeringcompetencies, design requirements and suppliers
Siemens has the technical and commercial capability to execute complexand large projects
Siemens has in-house capabilities to support financing schemes
Siemens provides equity participation in selected projects
Thank you very much for your kind attention!
