A Combined Cycle Power Plant is a more effective facility that generates electric energy by using the two cycles of a gas turbine and a steam turbine. In simple terms, it first uses natural gas to drive a turbine for electricity, and the heat produced by this process is then used to create steam, which in turn drives another turbine for more electricity. This combination allows the facility to use over 60% of the energy within the fuel, making it a more efficient than regular plants that only use around 33% of the fuel energy. Because it's so efficient, a lot of people are using it worldwide to produce clean electricity while using less fuel.
The typical heat rate of a gas power plant comes down to 7,000 to 10,000 BTU per kWh. More specifically, Simple Cycle Gas Plants tend to be in the area of 10,000 BTU/K and CTG Combined Cycle Plants are around 6,000 BTU/K. However, there are efficient plants out there that can go lower than this standard BTU heat rate.
The main factors that affect gas turbine efficiency are the temperature and pressure ratios of the inlet air. Operating at low inlet air temperatures and high atmospheric pressures boosts the turbine's efficiency. Humidification and chilling are used to control inlet air temperature, therefore increasing efficiency. When the humidity is high, there will be condenser flooding which affects efficiency. System design and maintenance practices also influence efficiency as well as variations in fuel type.
