The energy generating installation comprises a gas turbine (10) which is operated by steam injected via a steam line (16). The outlet (18) of the gas turbine (10) is connected with the heat exchanger (21) of a waste heat boiler (19). The waste heat boiler (19) contains a steam drum (22) connected to a preheater (24) and a steam generator (23) of the heat exchanger (21). According to the invention a solar steam generator (36) is connected to the steam drum (22) in a second circuit (39). The steam produced by the solar steam generator (36) is heated in a superheater (22) and then used for steam injection purposes. The energy generating installation offers high flexibility at high efficiency despite the unreliable availability of solar energy.
