The International Energy Agency's 4E Technology Collaboration Programme on Energy Efficient End-Use Equipment (4E TCP) report discusses the role of digital solutions in enhancing energy efficiency in motor systems across various industries. The implementation of simulation-based tools for production planning has enabled Smurfit Kappa in Sweden to lower energy intensity for paper production by 9% between 2017 and 2023. In Switzerland, Hamilton Bonaduz AG's integration of an adaptive air pressure management system in their compressed air systems resulted in a 16% reduction in electric energy consumption. Utilizing digital technologies outside operational hours allowed INNIO Jenbacher in Austria to decrease energy and compressed air use by about 30% on weekends. Coca-Cola HBC Austria achieved a 15% reduction in energy demand during normal operation with demand-based ventilation controls. BMW's Steyr plant in Austria utilized data acquisition and monitoring to reduce electrical and compressed air baseloads by 52% and 14%, respectively. Yorkshire Water in the UK applied electrical signature analysis to successfully manage pump operations and expect energy and CO2 savings up to 15%. Additionally, IoT solutions like PRiOT's sensor technology led to a 20% reduction in energy consumption by optimizing air filter maintenance at server sites. While digital solutions offer substantial benefits, companies need to address challenges such as investment costs, staff training, and process disruptions. Tailored strategies, comprehensive analysis, and continuous monitoring are essential for maximizing energy efficiency. Improvements in technology, such as artificial intelligence and machine learning, hold promise for future advancements in industrial energy optimization, potentially integrating with renewable energy sources.
