Natural gas is one of the most used energy resources in the world. The authors propose the method for reducing the costs of natural gas procurement, which consists in the use of a tool for managing the demand for natural gas consumption by industrial enterprises.The article contains the authors' description of the mechanism for reducing the costs of natural gas procurement at the level of the UGSS of Russia through the application of the demand management mechanism. Based on the characteristics of the technological and market environment, the authors develop a model for price-dependent management of natural gas consumption in an industrial enterprise, with the definition of key model blocks and the sequence of functions performed.The key element of the developed model of price-dependent management is the unit for fulfilling the forecast of natural gas consumption. The article analyzes the characteristics of the graphs of natural gas consumption by various types of industrial enterprises at different periods. The authors reveal a list of factors affecting the characteristics of natural gas consumption schedules by industrial enterprises. The influence of the identified types of factors on gas consumption in various industries has been assessed. Based on the revealed features, the authors developed a model for forecasting short-term demand parameters for gas consumption by industrial enterprises, based on using a combined forecasting method that combines the use of statistical methods and the method of expert assessments.The developed combined model for forecasting the parameters of natural gas consumption makes it possible to significantly improve the accuracy of forecasts by breaking up the consumption schedule by the types of gas use, taking into account the specifics and the level of influence of factors within each direction of consumption, and using the most suitable methods for each group of prediction methods. The practical importance of the developed model lies in the possibility of its use for forecasting the parameters of natural gas consumption by any types of industrial enterprises in the context of price-dependent energy management in order to minimize them.

The article is devoted to the development of a model and a set of methods for improving the efficiency of using small-distributed generation systems. The basis of the developed model is the integration of methods of price-dependent demand management for electricity and natural gas with a system of small-distributed power generation. The developed management model allows electricity consumers to reduce the cost of purchasing energy resources in comparison with the cost of electricity supplied from energy companies, based on the analysis of price indicators for the supply of electricity from regional energy markets and the terms of natural gas supply. The article presents the results of the pricing principles analysis for all components of the electricity and natural gas cost. The possibility of complex price-dependent demand management for the consumption of electric power is demonstrated through the management of electricity generation schedules by a small-generation system and schedules of gas consumption spent on electricity generation by a system of small-distributed generation. The complex of methods of price-dependent power consumption developed by the authors, taking into account the use of the system of small-distributed generation, can be adapted to the use by various types of electricity consumers that purchase electricity in the energy markets of various countries of the world.
