For industrial consumers with a simple dependence (or close to it) of energy consumption on the volume of output, the possibility of assessing the conditional- constant component of costs using the one-factor model “consumed energy resource-volume of output” is considered. The article highlights the concept of general-plant conditional-constant energy consumption and technological one, which is associated with the heating and maintenance of technological equipment in a working condition. For natural gas used in both the technology of cement production and glass production, the technological conditional-constant component is determined by the cost of energy to maintain the furnaces in a working condition. Using the example of a modern enterprise for the production of nitrogen fertilizers, an assessment of the conditional-constant component of electricity consumption for various industries was made in conditions of changing the production program. For a group of 88 industrial electricity consumers and 32 industrial consumers using either fuel (natural gas) or thermal energy in the technological process, the weight of the conditional-constant component of the consumption was investigated according to the production load. It is shown that industries with a higher weight of the conventional-constant component in the total energy consumption also have a greater horizontal regulation capacity for energy efficiency, i.e. the ability to change the total and specific energy consumption while changing production volumes. |
