Abstract

   Statistics show that energy is one of the highest operating costs in a manufacturing enterprise. So, improving energy efficiency can lead to a significant increase in profits and reduce the impact of the enterprise on the environment. To increase the performance of energy efficiency activities, it is necessary to implement an energy management system. One of the components of this system is energy monitoring, which, in turn, is based on the periodic collection and analysis of data to assess the state of the monitoring objects in terms of energy efficiency. In this paper, the role and place of energy monitoring in the energy management system of an industrial enterprise are noted. The paper proposes the concept of creating energy monitoring system in industrial companies, which is based on the combination of a monitoring system based on specific energy consumption, and usage of group energy characteristics of production facilities. Implementing such energy monitoring systems will allow to conduct operational control of energy efficiency of production facilities by creating individual systems for monitoring energy efficiency, as well as successfully carry out such monitoring at the enterprise and its subdivisions over longer periods of time using specific energy consumption indicators. It also provides general guidelines for conducting energy monitoring. These guidelines were formed based on the results of studying various methods and scientific publications in the field of energy monitoring, as well as on the basis of practical experience in the development and implementation of energy management systems. Particular attention is paid to the issues of processing and analysis of information about the objects of energy monitoring of industrial enterprises. The practical application of the concept of creating energy monitoring systems envisages gradual improvement of the existing monitoring system based on the specific energy consumption, which will be further completely replaced with individual energy efficiency monitoring systems.  

Highlights

One of the main factors that determine the production processes for a lot of industries is the cost of energy flows
The problem of energy saving and energy efficiency (EE) is one of the most urgent and its solution should be carried out taking into account the European Union (EU)-Ukraine Association Agreement, which provides for the implementation of the requirements of Energy efficiency directive (Directive 2012/27 / EU) that established a set of binding measures to help the EU reach its 20% energy efficiency target by 2020 [3]
Considering the advantages and disadvantages of determining the specific energy costs and building energy efficiency monitoring systems, it can be argued that one of the promising directions for further development of the methodology of such monitoring is the establishment of industrial energy monitoring system (IEMS) at production facilities

Summary

Introduction

One of the main factors that determine the production processes for a lot of industries is the cost of energy flows. At the start of the IEMS operation, it will be necessary for some time to apply both of the above approaches to energy efficiency monitoring: at the level of enterprise as a whole and its subdivisions – on the basis of specific costs of electricity, and at the level of technological facilities (individual plants, units, processes or their groups) – offering them individual EMS. Developing and implementing IEMS at industrial sites allows this monitoring to be operational at the level of individual units, installations or processes, and enables, with the gradual increase in the number of individual EMSs built, improve the accuracy and validity of determining target specific costs of electricity, as well as to carry out operational monitoring of energy efficiency at the enterprise level as a whole and its subdivisions.
