One of the promising areas of increasing energy efficiency used in international practice is the demand-side management (DSM). It is implemented through price-dependent management of the schedule of consumers' demand for electric energy. Considering significant share of expenditures on electric power in the structure of the large consumers' energy consumption, we analysed the potential for introducing price-dependent management of expenditures on electric power as a tool for managing demand for electricity in the Russian regions. The study's information base were price characteristics of the supply of electric power, the actual hourly demand for electricity consumption, and the number of hours of the combined daily maximum of the Russian regions' electric power system for the period from 2016 to 2018. We applied the following methods: analysis and synthesis, mathematical and statistical analysis, method of constructing positioning maps. We developed a map for assessing the predictability of the hour of the daily maximum of a regional electric power system, the level of which determines the possibility of using price-dependent management in general. The map demonstrates the ratio of the developed indicators "Integral indicator of the cyclical nature of the regional energy system" and"Integral indicator of the energy system's maximum in Russia". Additionally, we used the unifying characteristics "Integrated indicator of the predictability of the hour of a regional energy system's combined maximum" and "the coefficient of the price of electric power". That allowed us to group the Russian regions in accordance with the degree of appropriateness of using price-dependent mechanisms for managing energy expenditures by the component "cost of electric power". The study's main result is the development of new tools for assessing the potential of using price-dependent management of expenditures on electric power, such as a "predictability map" and a regional grouping. We elaborated a set of methods for assessing the degree of potential efficiency in the use of price-dependent management of expenditures on electric power by electricity consumers in the Russian regions. The proposed approach can be used for developing federal and regional programs for the integrated demand-side management for electricity consumption. © 2020 Institute of Economics, Ural Branch of the Russian Academy of Sciences.

The article studies the features of the global fuel and energy sector's development under structural transformational changes from 1971 to the present day. In the materials, the author analyzes the fuel structure of global generated electricity, compares the structure of global natural gas consumption, calculates and evaluates the dynamics of global consumption of various energy sources per capita, and analyzes the dynamics of global indicators of energy content of various energy sources to gross domestic product at purchasing power parity. Furthermore, an empirical analysis of indicators of the structure of change in renewable energy sources' share of global gross production of electric power energy is conducted, as is the analysis of the structure of investments into the development of the renewable electric power industry in some countries, as well as global CO2 emissions since 1990. Firstly, the study reveals environmentally friendly and cost-effective energy sources such as natural gas and renewable energy sources technology, which strengthen their position in the global energy balance in the fuel structure of electric power generation while displace non-environmental petroleum and coal. Secondly, it has been proven that the indicators of the global energy efficiency level, calculated based on the energy content of all major energy sources consumed globally over the last century, are constantly dropping. The article describes the structure of a significant growth in renewable energy sources share of global gross production of electrical power. This trend is possible due to the accessibility of the technology for the production of renewable energy sources, the rise in the cost of crude hydrocarbons on global markets, "green" energy support at the state policy level in most countries, and massive investment in renewable energy sources. As a result of the study, it was concluded that the policy of managing the development of the global fuel and energy sector has a significant impact both on its future and on the development of the global economies of the world's countries, primarily the Russian Federation.

One of the worldwide modern instruments to increase power efficiency is the price-dependent electricity consumption. It is one of the elements in managing the demand for power consumption. The programs of price-dependent power consumption are globally relevant. However, in Russia, their development is still on a conceptual phase. This paper analyses regional tariffs for the power transmission from the perspective of encouraging consumers to price-dependent demand management for electricity consumption. We examine the structure of final electricity tariffs for various categories of consumers as well as identify the percentage rate for the electricity transmission for each category. We consider the methodology of single-part and two-part tariffs for electricity transmission, their structure, and advantages of application. On the example of Volga Federal District tariffs, we have calculated single-part and two-part tariffs for the power transmission in industrial enterprises in terms of three typical schedules of electricity consumption. To compare the efficiency of the price-dependent demand management for the electricity transmission in different regions of Russia, we have introduced the indicators "coefficient of the transmission tariff" and "integral coefficient of the transmission tariff". Furthermore, we made calculations for 65 regions of Russia entering the price zones of power wholesale market. As a result of the analysis, we divided Russian regions of Russia according to the indicator of "integrated coefficient of transmission tariff" in 3 administrative groups. For each group, we have developed recommendations on price-dependent demand management for power transmission. The theoretical significance of the research consists in the development of methods for the analysis and selection of the most appropriate industrial enterprise tariff for electricity transmission. In practice, regional authorities can use the developed groups of regions to change the structure of regional tariffs in order to stimulate consumers to price-dependent power consumption. Moreover, the algorithm for calculating tariffs for electricity transmission can be applied by the industrial Russia enterprises in price-dependent demand management of power consumption to choose an optimum tariff and reduce costs on power transmission. © 2018 Economy of Region.

The article is devoted to the analysis and evaluation of the potential of the electric structure of Russian regions. The authors introduce the category of the "potential of electric infrastructure" understood as the integrated indicator characterizing the regional power infrastructure. The authors assess the potential of electric infrastructure on the basis of the proposed methodology and the developed indicators: "the ratio of electricity tariff", "coefficient of technological connection", "integral coefficient of electric infrastructure potential." The article presents the results of testing the developed method on the example of the analysis and evaluation of the characteristics of electric power infrastructure of Russian regions. The result of testing was the construction of a rating of regions by the level of electric infrastructure potential. On the basis of the calculated parameters of electric infrastructure potential, we developed a map and a matrix of indicators of the potential of electric infrastructure of Russian regions. This allowed to classify Russian regions to several groups. The practical value of the map and matrix of the potential of electric infrastructure of Russian regions is the possibility to conduct the comparative assessment of the characteristics of the electric infrastructure of the territorial units and enables more informed management and decision-making concerning the choice of the most effective industrial investment. In addition, based on the developed indicators of electric infrastructure potential, the authors propose the improvement of the existing methods for the evaluation of investment potential of Russian regions. Previous research on the investment potential of regions does not take in account the characteristics of the potential of elecrtic infrastructure. The obtained results are of a theoretical and practical importance and can be used for the energy efficiency management of territorial units as well as for the analysis of the potential of electric infrastructure of possible industrial investments with the aim of increasing it. ; Представлена характеристика электроструктурного потенциала регионов.
