The use of biogas as a renewable energy source is already a reality, being applied in both production of heat as in generation and cogeneration of electric energy facilities. In this sense, the technical contributions directed to the increase of the efficiency in energy generation are mainly associated to the development of technologies in terms of propulsion systems. Adhering to this premise, this study aims to develop a test facility dedicated to the efficiency analysis of small motor generators (power less than 75 kW) using biogas as the main fuel, taking as reference the ABNT and international (ISO, DIN, IEEE, etc.) regulatory standards for performance evaluation. In this context, it has inserted the specification of precision instruments to be used in the test bench, in order to monitor the main operating parameters of the motor generator. This installation was designed in order to guarantee optimal control conditions of electric power production process and to allow the simulation of the various usual operating situations in industry. Aiming to establish a high-quality standard of the tests based on reference standards, consistent with certification procedures for motor generators, the safety aspects were considered, as well as the building infrastructure which was studied and treated to achieve adequate acoustic insulation, thermal insulation, vibration attenuation, besides electrical protection systems against outbreaks (voltage peaks and electric current). And, a study was also carried out to provide conditions of hygiene and safety at work, in accordance with current norms. As result of the developed work, a project of an efficient and controlled test facility of motor generators was obtained, capable of being operated according to a graded and discrete load dosage criterion, respecting the necessary time for the stabilization of current and voltage, as a first stage. And it was also designed so that, in a second stage, the operational controls of the facility allow the energy produced to be injected into the University's own electricity grid, automatically, in order to reduce the university's energy consumption.
