[0001] A plant (10 110) for the production of electric energy comprises a fuel boiler (11) in which a fluid is heated in order to produce steam a turbine (15) which is connected to an electric generator (16) and to which said steam is conveyed and a condenser unit (19) which re condenses the fluid output from the turbine so that it may be conveyed back to tire steam generator. The return fluid along the path from the condenser unit (19) to the boiler passes through a preheating unit (22) which receives heat from the turbine steam bleed offs (23) and from a thermodynamic solar field (25). By making suitable use of the heat produced by the solar field (25) and contained in the heat carrier fluid which passes through it it is possible to increase the overall efficiency of the plant (10 110). Furthermore advantageously the heat carrier fluid which passes through the thermodynamic solar field receives heat from the fuel boiler via a suitable exchanger (32) which allows an increase in the productivity of the solar field itself and moreover uses the residual heat of the main plant which otherwise would be lost.
