Combined Cycle Power Plants

Combined Cycle Power Plants produces electricity in both Gas turbines/Gas motors and Steam Turbines.The system is combination of Kogeneration Plant followed by Steam Turbine.The exhaust gases with 550-575 C temperature is sent to HRSG unit and Steam is produced. Then steam is sent to Steam Turbine and electricity is also produced at that stage.

Comparing to Simple Cycle systems the efficiency of Combined Cycle Systems have electrical efficiency of 55-60 % while the efficiency of Simple Cycle systems is about 30-35 %.

GSD as being EPC , construct Power Plants on turnkey basis including civil works, E&M installation works, material procurement,commissioning and start up.
