It is a derivative of the General Electric CF6 aircraft engine and considered to be one of the most reliable industrial gas turbines ever. These turbines were developed for use on airplanes and became the first gas turbines to be used for the production of electricity. Aircraft engines were initially adapted for stationary power use. The primary role for aeroderivative gas turbines during this early phase was for peaking power. Heavy duty gas turbines As the advantages of aeroderivative gas turbines were recognized, a new type of dedicated industrial or heavy duty gas turbine was developed. The heavy duty engines were designed directly for the main baseload generation market.
