Assessing energy efficiency factors in industrial companies

Abstract

The relevance of the study is due to the fact that changes in the energy management policy at the national level, rising energy prices and increased state environmental control over production prompt industry to develop effective organizational and technical solutions in the field of energy management. The aim of the study is to identify energy management factors that determine the success or failure of the implementation of energy efficiency measures in industrial companies. In the empirical part of the study, the case-stage method was used to analyze the energy management practice of large metallurgical enterprises, where the problems of energy conservation are especially acute due to the high energy intensity of production. A promising direction in such an environment is the integration of structural components used to support decisions and social components represented by staff commitment and accumulated energy-efficient human capital. The main results can be applied in the practice of energy system management in the development of strategic planning processes, the adoption of sound investment decisions and the formation of energy-efficient human capital.

Sustainable energy efficiency in aluminium parts industries utilizing waste heat and equivalent volume with energy management control system

“…This should be supported by good collaboration starting within the company and involving marketing, production planning, inventory control, production, utilities, etc. [41]. A stable workload for the production department will ensure op timal and efficient performance of the produc tion process, utility, and energy.…”

Assessment of the impact of the industrial enterprise on the environment by determining the integrated (generalized) energy efficiency performance indicator

“…In this way, we determine the efficiency of using primary energy resources in the production of thermal energy [6]. Since the consumption of heat energy in the enterprise is made from several (from the centralized network, renewable and non-renewable) energy sources in the territory of the enterprise, we will combine them into one source, that is, we will consider it as a hybrid heat energy source consisting of several energy sources [6]. To do this, we write the (3) expression in the following form:…”

Intelligent Integrated Model for Improving Performance in Power Plants

“…6 shows that authors from 41 countries published reports relating to reliability and performance in the maintenance during the period 2014-2020. The nationality distribution of 110 technology-related papers in numbers and showed that the main contributors are from the United States (27), followed by China (18); Germany (10); United Kingdom (9); South Korea (8); Australia (7); Iran (6); Brazil, France, and Italy (5 each); Belgium, India, and Norway (4 each); Canada, Malaysia, Denmark and Sweden (3 each); Turkey, Belgium, Netherlands, Poland, Romania, and Spain (2 each); Argentina, Belgrade, Colombia, Czech Republic, Finland, Indonesia, Ireland, New Zealand, Pakistan, Russian, Saudi Arabia, Scotland, Slovakia, South Africa, Georgia, Slovenia, Japan and Algeria (1 each).…”

“…Lack of intelligent integration of performance and poor automation in the maintenance of power plants causes losses that are roughly 2.5 times higher than those attributed to hardware failure [4]. In terms of maintenance, personnel performance is closely related to energy management performance, and is thus a factor in energy consumption and human errors [5,6], although further investigation is required to determine the interaction between personnel, energy management, and the critical success factors (CSFs) associated with thermal and gas power plant maintenance [7].…”
