Combined cycle

A Combined Cycle power plant uses a gas turbine to drive an electrical generator, as Simple Cycles do; in addition, it recovers the heat of the turbine exhaust gases to generate steam. This is run through a steam turbine to provide supplemental electricity. 
All Ansaldo Energia Heavy-duty Gas Turbines can be profitably used as heat sources in a Combined Cycle plant, ensuring reliable base load as well as part-load operation
The overall electrical efficiency of an Ansaldo Energia Combined Cycle plant can reach 62,5% with the GT36 H-class gas turbine, with extremely contained start-up time due to intrinsic engine flexibility.
