Factory Energy Management System (FEMS) is a comprehensive system used in industrial settings to monitor, control, and optimize energy usage. It integrates various technologies and software solutions to track energy consumption, identify inefficiencies, and implement strategies to reduce energy waste and costs. FEMS typically includes components such as energy monitoring devices, sensors, data analytics software, and control systems. By providing real-time insights into energy usage patterns and performance, FEMS helps industrial facilities improve energy efficiency, meet sustainability goals, and reduce environmental impact. It plays a crucial role in enhancing operational efficiency and competitiveness in the manufacturing sector.
