The gas turbine installation has a gas turbine with two stages (HD, MD) of different pressures and an energy exchanger (ET) connected as upper stage of the gas turbine. High-pressure air compressed in the energy exchanger (ET) is fed to a burner (NB) acting on the energy exchanger (ET) and to a combustion chamber (BK) of the gas turbine. Propellant gases discharged by the energy exchanger (ET) and a high-pressure stage (HD) of the gas turbine are fed to a low pressure stage (MD) of the gas turbine. The gas turbine arrangement is intended to be distinguished by simple construction and high efficiency and to be advantageously influence in its mode of operation in respect, for instance, of rapid load changes. This is achieved by the following measures: - a heating element (e.g. H2) is provided in a leg (e.g. HD2) carrying high-pressure compressed air, - a cooling element (e.g. K1) is provided in a propellant gas-carrying leg (e.g. MD1) branching off from the energy exchanger (ET), - heating (e.g. H2) and cooling element (e.g. K1) are interconnected as a heat exchanger (e.g. W12) for the purpose of recuperation or regeneration of heat.
