Combined cycle power plant efficiency: what you need to know

A combined cycle power plant is a type of power plant that uses a gas turbine cycle and a steam turbine cycle in a sequential manner to generate electricity efficiently. As such, both cycles collaborate to transform heat energy into mechanical energy: the exhaust gasses produced by a gas turbine are used to produce steam, thus extra power is ...

Cogeneration

Cogeneration or combined heat and power ( CHP) is the use of a heat engine [1] or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover ...

What makes combined cycle power plants so efficient?

As you can see from the GE case, the efficiency of combined cycle power plant has already surpassed the 60% mark. This is how the industry calculates this efficiency: h cc = h c1 + h c2 – h c1 h c2 Where; h cc = Combined Efficiency. h c1 = Efficiency of Cycle 1. h c2 = Efficiency of Cycle 2. Assuming the first cycle efficiency is 40% and the ...
