Cogeneration / trigeneration systems are being utilized as a solution to reduce the dependency of the electrical grid and to rise natural gas efficiency use. Several cogeneration / trigeneration systems configurations and prime mover power can be applied, the selected solution for a building or process is normally defined based on the existing building/process energy demands. Several studies revealed that cogeneration / trigeneration systems can be competitive with high efficiency centralized thermal plants. The comparison between cogeneration / trigeneration systems and centralized thermal plants and local heat/cool production needs to be done taking into account the energetic value of the cogeneration/trigeneration products and the energy conversion efficiency of the separate production of the same amount of their products (electricity, heat and cool). Since energy demands in buildings/process varies as day hours, weekdays, weather season, activity, etc, energy performance prediction methods should be utilized to evaluate the annual averaged efficiency. In this paper some engine cogeneration / trigeneration systems configurations are evaluated and compared with the separate production of their products. The results of some annual efficiency performance is discussed. Sisterm Thermal Systems has a research project funded by Fapesp (São Paulo State Research Foundation) to develop high efficiency cogeneration / trigeneration systems.
