The focus of this research is a case study concerning an Energy Auditing that was conducted in a dairy agribusiness located in the city of Guaira, in the extreme west of the state of Paraná. In this context, this research aimed to: perform an energy auditing of its facilities by analyzing the energy consumption associated with the processes, systems, and existing equipment, to identify and quantify the loads installed in agribusiness, energy consumed and checking the power demanded in each of them and determine the potential for energy conservation for the existing final uses at the company, by identifying opportunities to implement measures thus optimizing the use of energy, and perform an economic feasibility study that aims to implement the energy efficiency measures. After analyzing the energy demands and the equipment installed in the agribusiness, it is highlighted the possibilities of increasing the supply of electricity only reducing waste in the manufacturing sector. The economic analysis indicates a payback of 30 months and Internal Rate of Return of 3.93% per month. With the implementation of the proposed interventions, it is obtained a reduction of 11,490.50 kWh month-1 (monthly savings of 7.26%).
