This article highlights current methodologies for optimization in energy-intensive processes controlled by Electric Motor Drive Systems (EMDS). Methodological intervention proposals such as technological substitution, demand management, and operational control offer benefits in terms of energy sustainability, but uncertainty in evaluating the impact of the results remains unresolved. In this study, the process load factor indicator is used to support the analysis and prioritization of intervention routes and energy monitoring. Additionally, a case study is presented, evaluating the possibilities for intervention and energy savings in an EMDS system for pumping, along with the use of an integrated energy efficiency indicator for monitoring the system's energy performance.
