A gas-turbine plant of the air-storage type comprises a multi-stage gas-turbine having high and low pressure sections, a flow medium heating device located between the high and low pressure sections of the gas-turbine, a dynamoelectric machine coupled to the gas-turbine, a compressor also coupled to the dynamoelectric machine and an air-storage tank connected between the compressor outlet and the inlet to a heat exchanger heated by exhaust gas from the gas-turbine and through which the medium flows to the high pressure section of the gas-turbine. Two control valves are located in the outlet piping for the flow medium from the heat exchanger which are set to permit the high pressure section of the gas-turbine to be by-passed and the flow medium delivered directly to the heating device during starting of the gas-turbine whereas after the heat exchanger has been heated to between 50 and 100% of its mean operating temperature, the control valves are re-set so as to again permit all of the flow medium to be delivered to the high pressure stage of the gas-turbine.
