Abstract: This study assesses energy management practices in the automotive sector of Poland’s Silesian Voivodeship, a highly industrialized region. Using structured interviews with 40 manufacturing firms, it examines the adoption of energy monitoring, submetering, Energy Performance Indicators (EnPIs), audits, and energy efficiency investments. The research addresses the problem of persistent energy waste and the difficulties many firms face in integrating ISO 50001-aligned energy management into daily operations, where declared policies often outpace actual practices. Results show that 92.5% of firms monitor total energy consumption, but only 40% implement submetering, and 45% use EnPIs. Half have conducted energy audits, and 85% report taking energy-saving actions such as lighting upgrades, equipment modernization, and thermal improvements. However, no companies reported measurable energy or cost savings, and few track investment outcomes quantitatively. While energy awareness is widespread, many practices appear to be implemented in a tactical manner, potentially lacking strategic integration or consistent performance tracking. Larger firms are more likely to use audits and EnPIs, while smaller firms face barriers such as limited resources or technical expertise. The findings highlight a need for formalized EMS adoption, standardized energy governance, and greater use of performance-based tools such as EnPIs. By exploring EMS-aligned behavior without referencing management systems directly, the study provides a unique lens on the operational maturity of industrial firms.
