Introduction: The present study analyzes the use of SCADA systems (Supervisory Control and Data Acquisition) as a tool for efficient energy management in the agro-industrial sector, which is characterized by high energy demand in processes such as irrigation, refrigeration, and storage. The research aimed to develop and simulate, through the CoDeSys software, a computational model of automated irrigation capable of monitoring and controlling critical variables of energy consumption in real time. Based on theoretical frameworks of industrial automation, energy efficiency, and sustainability, the study adopts ISO 50001 as its theoretical foundation, as well as studies that emphasize the integration of SCADA, fuzzy control, and the Internet of Things (IoT) within the context of Industry 4.0. The methodology involved modeling a system composed of sensing, actuation, and intelligent control modules, which was subjected to different experimental scenarios simulating environmental variations and operational failures. The results indicated average reductions of 12.5% in water consumption and 9.3% in energy consumption compared to conventional systems, in addition to efficiency gains and immediate response to failures. The discussions demonstrate that automation combined with intelligent control enhances the rational use of resources and contributes to the environmental and economic sustainability of the sector. The study reinforces the importance of automated energy management in promoting competitiveness and sustainability, in alignment with Sustainable Development Goals (SDGs) 7, 9, 12, and 13 of the 2030 Agenda. Objective: The objective of this study is to develop and simulate, through CoDeSys software, a computational model of automated irrigation based on SCADA systems (Supervisory Control and Data Acquisition) aimed at efficient energy management in agroindustry. Theoretical Framework: It is based on concepts of industrial automation, energy efficiency, and sustainability, supported by previous research and the ISO 50001 guidelines (ABNT, 2018). The integration between SCADA, fuzzy control, and the Internet of Things (IoT) in the context of Industry 4.0 is emphasized. Method: The study employed simulations in the CoDeSys environment, modeling an irrigation system composed of sensing, actuation, and intelligent control modules. Three experimental scenarios were tested, considering climatic variations, operational failures, and unexpected events, with data collection on water, energy, and efficiency. Results and Discussion: The results showed an average reduction of 12.5% in water consumption and 9.3% in energy consumption compared to conventional systems, demonstrating efficiency and sustainability gains. The fuzzy control exhibited better performance under environmental variations, strengthening data-driven decisionmaking. Research Implications: The application of SCADA fostered technological, economic, and environmental advances, aligned with SDGs 7, 9, 12, and 13, reinforcing the role of intelligent automation in the energy transition of the agro-industrial sector. Originality/Value: The study stands out for integrating emerging technologies and applying simulation to the agro-industrial context, offering a practical contribution to sustainable energy management and advancing Industry 4.0 in rural environments.
