Abstract

The work shows the main features of the management of industrial enterprises' energy saving potential. Taking into account the significant increase in the cost of energy resources for the last time the use of the energy saving potential of industrial enterprises is a promising and quick way to reduce energy consumption, and, accordingly, the energy consumption of products. Such approach allows increasing profitability of the company, decreasing environmental pressure on the environment, using internal reserves of the company for optimization of its work. The definition of the concept of the potential of energy saving of the industrial enterprise is substantiated, approaches to its definition are considered. It is required to determine the potential of energy saving of the enterprise in thermal units. One of the effective directions of energy saving is the use of the potential of electricity. Indirect combustion of primary energy resources is currently unreasonable. One of the ways to reduce the consumption of natural gas, the price of which has increased dramatically, is the use of heat pumps. These devices allow pumping thermal energy from the air, soil or water while consuming 3...5 kW of thermal energy per year for production close to 1 kW of electric energy per year. The results of the real energy audit of the industrial enterprise are reviewed, and the cost of heat energy units generated from various sources is given. A set of economically sound measures of energy saving to be implemented in the enterprise was suggested. Net present value and environmental effect from implementation of the particular approach are determined. The value of the discount coefficient for calculations of economic feasibility of the measures was substantiated. Absolute and relative optimal energy saving potentials for all measures were calculated. The optimal limit value of the energy saving potential of 10% at values above which the energy saving measures should be implemented.
