Industrial energy efficiency starts with the team that operates the plant rather than with the purchase of new equipment

Industrial energy efficiency is commonly associated with equipment replacement and the adoption of new technologies. The literature on the so-called energy efficiency gap shows, however, that a relevant share of the savings potential depends on organizational, managerial and behavioral factors, including the way facilities are operated and maintained. This article discusses the role of operations and maintenance teams in improving the energy performance of process plants, with emphasis on the chemical, petrochemical and energy sectors. The research follows a qualitative approach, based on a narrative review of the scientific literature and on the analysis of technical standards and documents from international organizations. The discussion covers non-technological barriers to efficiency, energy management systems, continuous improvement, the reduction of process variability, asset reliability, operators' tacit knowledge and the multiple benefits of efficiency measures. The findings indicate that operating practices, maintenance routines, technical competence and indicators embedded in daily work shape energy performance as much as the installed technology. The study concludes that investments in equipment yield limited results when they are not accompanied by structured management and by the training of the teams that make operational decisions every day.
