This paper proposes a scheme of cogeneration plant that allows to minimize the surplus of thermal energy and electricity produced. Using the data of consumption of thermal energy and electricity of a hospital in south Italy, it was proposed a cogeneration plant added by compression refrigerators and heat pumps and absorption refrigerators. After analyzing the thermodynamic parameters to assess the energy savings achieved as a reduction of primary energy n passing from conventional energy production to in cogeneration with integration of auxiliary machines. It was suggest to adapt, according to the type of energy to be supplied, the components added by assessing the reduction of primary energy obtained with a scheme of this type adapted to the energy requirements monthly. The results obtained were assessed with efficiency values lower than those attributed to thermal machines to take into account that these machines are used partialized working because it supplies a power reduced with respect to the maximum possible value, then, with efficiency values lower. The results obtained have confirmed the need to fit the system to the energy requirements for the minimum consumption of thermal plants.
