Induction generators operate by mechanically turning their rotors faster than synchronous speed . A regular AC induction motor usually can be used as a generator, without any internal modifications . Induction generators are useful in applications such as mini hydro power plants, wind turbines, or in reducing high - pressure gas streams to lower pressure, because they can recover energy with relatively simple controls . </P>
