Energy cogeneration is an approach that allows the application of various technologies capable of simultaneously or continuously generating useful mechanical energy that generally ends up being transformed into electrical energy and, on the other hand, also the generation of useful heat for its use in different processes of the industry. Nowadays, the largest shopping centers in the city of Lima are choosing to use self-generation systems, not only to reduce operating costs at peak hours, but also to satisfy a large part of their demand, leaving the connection to the electricity grid for special cases such as the presence of excess demand. In this context, there is the possibility of taking advantage of the residual heat from the generating machines to obtain chilled water that could be used in the air conditioning system of the shopping center and thus reduce the economic costs of energy. In this paper, the demands for electrical energy and air conditioning for a shopping center in the city of Lima are determined, taking as reference typical load profiles for this type of establishments taken from the manual for the design of combined heat and power systems of ASHRAE (2015), from which design recommendations for this type of systems are also taken. Subsequently, a preliminary design of the system is carried out that includes the primary motor, alternator, energy recovery systems and absorption chiller that uses hot water as a heat source, through which an annual primary energy saving of 43.14% is obtained compared to the conventional system that buys energy from the grid. On the other hand, the analysis of compliance is carried out based on the qualification criteria specified in the cogeneration regulation No. 037-2006, which mentions minimum values of Equivalent Electric Performance (REE) and C ratio that the power plants must meet. cogeneration to be able to inject surplus power and electrical energy into the National Interconnected Electric System (SEIN).
