This studio of IMPACT AND EVALUATION OF TRIGENERATI0N IN THE SIZE OF A COGENERATlON SYSTEM FOR HOSPITALS. Is caused by growing concern about the environment and for the responsible use of primary energy with high efficiency technology. The analysis of the energy needs of two hospitals Aims at the study of trigeneration to cover the needs (Electricity, heating, hot water and refrigeration) in hospital complexes, this is done by studying the quality of fuels and their thermalloads and by alternative internal combustion engines. By the high energy efficiency that is reached with the trigeneration we can achieve a considerable saving of fuel and therefore a reduction of emissions of C02, 502, and NOx causing the greenhouse effect and sale of surplus energy. The explicit objective of this research is to perform a study of energy supply through trigeneration for two hospitals, using the modeling by Excel 2010, for two hospitals of 1550 and 950 beds, considering the standards of quality of different energy supply technologies, the methodology of work begins in the collection of information, energy data and bibliography; Including their analysis, sensitivity and study. The economic technical study of the energy supply will allow us to find different scenarios to make decisions. A simulation was made with diesel fuels, biodiesel, biogas and natural gas. Giving result after the 04 simulations, the one that generates greater economic profit and less time of recovery of the investment, the scenario one “Natural Gas“, which gives an expected equivalent electrical performance of the installation of 67.01% and an electricity-vapor ratio of more than 65%. The discount rate used for all analyzes is 11% in a pessimistic scenario; according to this we indicate that the cogeneration has a higher NPV, higher IRR and less recovery time with respect to trigeneration, but this is still profitable besides that it includes the cold system in its process, important for the summer months. The Edgardo Rebagliati hospital in the sensitivity analysis of natural gas (Rate “A“) shows a NPV of 1.9 million for trigeneration, unlike that of Guillermo Almenara Hospital of -2 million; But the Hospital Guillermo Almenara with sensitivity analysis in “B“ results in NPV of 2.5 million; which indicates that the trigeneration for complexes hospitals in general is profitable. Finally we chose the engines DEUTZ model TCG 2020 V20 - NATURAL GAS. Each is integrated into a cogeneration module with a nominal electric power of 1989 kWe. It is recommended that the state define the energy potential of hospitals with the system shown and it can compete in the sale of surplus energy to the national interconnected power system with the private sector, improving competitiveness.
