A combined gas turbine-Rankine cycle powerplant with improved part load efficiency is disclosed. The powerplant has a gas turbine with an organic fluid Rankine bottoming cycle which features an inter-cycle regenerator acting between the superheated vapor leaving the Rankine turbine and the compressor inlet air. The regenerator is used selectively as engine power level is reduced below maximum rated power.
