The CCGT plant contains two turbines that both generate electricity. The first turbine is driven by combusting gas, which in turn drives a generator to produce electricity. This process produces exhaust gases, still containing useful and recoverable heat energy. The exhaust gases will pass through a heat recovery steam generator (HRSG) where this heat will be extracted from the exhaust gases to raise steam. The resultant steam will be provided to a condensing steam turbine and will expand across the steam turbine blades. This expansion will, as within the gas turbine, rotate the turbine and drive the same or an additional electrical generator to increase the electrical output of the Generating Station and its efficiency.
