Abstract [en]

Improved industrial energy efficiency (IEE) is a cornerstone in reducing greenhouse gas emissions. The implementation of Energy-Efficiency Measures (EEMs) is the primary means of improving IEE. However, EEMs are not always stand-alone measures. Rather, they are intertwined in the production and other sub-systems calling for a systems approach to be applied. In industry, nearly 70 percent of the power use emanates from motor systems. Electric motor systems can be categorized into three system levels: motor, core motor system, and total motor system, where the large energy-efficiency potential is to be found in the upper system levels. However, previous research has been scarce in showing on which system levels the highest potential for improved IEE is found. Based on a dataset of electric motor system measures from the Swedish energy policy program for improving energy efficiency in energy-intensive companies (PFE) consisting of about 1250 EEMs saving 900 GWh/year, the aim of this study is to analyze, using an extended version of the system level categorization, on which system levels the implemented measures are to be found.
