The article provides a general characteristic and detailed analysis of the main spheres of the fuel and energy complex of Lviv Oblast. The paper proves the importance of development of the fuel and energy complex for the economy of Lviv Oblast and the welfare of its residents, for it fulfills the needs of the entire economic complex in fuel and energy, creates preconditions for development of various types of production, forms the basis for improvement of energy security of the region and country in general. The peculiarities of development of the fuel and energy complex were determined, the main of which are: large amount of coal extracted by mining, small-scale extraction of peat, absence of major electric power stations and high percentage of incoming electric energy from other regions. The paper gives a characterization of the energy balance in the Oblast, and also structure of reserves of coal mines and oil deposits. Areas promising for extraction of bituminous and brown coal, oil, gas, peat and other fuel resources were determined. The structure of consumption of fuel-energy resources by types of organic fuel was determined. Patterns of consumption of the main types of energy carriers in the region were distinguished. The structure of capacities of alternative energy resources in Lviv Oblast was determined. We determined the reasons for the low efficiency of use of natural resources and peculiarities and problems of the development of the energy sphere in the region, the main of which are the unsatisfactory technical condition of the objects of the fuel and energy complex, non-effective system of management in the sphere, absence of new sources of providing primary energy resources. We suggested recommendations on increasing the efficiency of functioning of the fuel and energy complex on the basis of use of non-traditional types of energy sources, i.e.: energy of sun, wind, biomass of solid fuel and others, which would allow natural and financial resources to be saved.

The paper considers spatial organization of energy facilities with an emphasis on modern practice of the Republic of Belarus. The efficiency of enterprise operation in any industry including power industry is largely due to their architectural and planning organization. Knowledge of mechanisms and specific features of the changes taking place here makes it possible to justify a promising strategy for project activities, and therefore, it allows to manage development processes of the industry and thereby avoid many negative consequences. Energy facilities are a typological unit of industrial architecture, their formation has been started due to transition of industrial production to electric energy. Today the typology shows functional approach in architectural shaping, it includes a fairly large variety of constituent units and demonstrates a tendency towards diversification. In Belarus energy facilities in the architectural aspect of their classification are limited mostly to thermal power plants operating on different types of fuel. Currently the diversification is developing in the following areas: construction of hydropower facilities (small plants on reservoirs, medium power plants, low-pressure plants, run-of-the-river hydraulic power stations), alternative energy (wind power stations, photovoltaic power stations and biogas plants) and conventional energy (thermal power plant, mini-combined heat and power plant operating on renewable fuel). The results of Belarusian practice in construction of all types of facilities (hydropower, alternative and conventional energy), peculiarities of the architectural and planning organization of facilities at the current stage, correlation with global trends in the development of industrial architecture have been characterized in the paper. The paper has determined typological features of alternative energy facility architecture, opportunities and directions for implementation of architectural approaches, problems and prospects to develop scientific support for the project process.

Background/Objectives: The power demand of utility electrical power has stimulated the use of distributed energy for peak shaving. Distributed energy resources need to be monitored and controlled like Internet of Things.Methods/Statistical analysis: Distributed Energy Resources (DERs) are small scale electric energy system like Micro Turbine, Photovoltaic, Wind power, Small Generator and widely spread in Korea. For utilizing electrical device with Internet of Things, we need integrated system and adapt International Electrical Code like IEC 61850.Findings: To connect DERs with uninterrupted grid system, it required Closed Transition Transfer Switch (CTTS). Existing International Electrical Code presented some distributed energy resource by IEC 61850-7-420. However, the switch like CTTS is not presented. So, we described modeling of CTTS in IEC 61850 and verified monitoring data with TCP/IP.Improvements/Applications: The proposed modeling of CTTS not only combines the DERs with grid system but also conjugates smart grid system with IOT Technology.

Native American reservations are among the most economically disadvantaged regions in the United States; lacking access to economic and educational opportunities that are exacerbated by “energy insecurity” due to insufficient connectivity to the electric grid and power outages. Local renewable energy sources such as wind, solar, and biomass offer energy alternatives but their implementation encounters barriers such as lack of financing, infrastructure, and expertise, as well as divergent attitudes among tribal leaders. Biomass, in particular, could be a source of stable base-load power that is abundant and scalable in many rural communities. This case study examines the feasibility of a biomass energy plant on the Cocopah reservation in southwestern Arizona. It considers feedstock availability, cost and energy content, technology options, nameplate capacity, discount and interest rates, construction, operation and maintenance (O&M) costs, and alternative investment options. This study finds that at current electricity prices and based on typical costs for fuel, O&M over 30 years, none of the tested scenarios is presently cost-effective on a net present value (NPV) basis when compared with an alternative investment yielding annual returns of 3% or higher. The technology most likely to be economically viable and suitable for remote, rural contexts—a combustion stoker—resulted in a levelized costs of energy (LCOE) ranging from US$0.056 to 0.147/kWh. The most favorable scenario is a combustion stoker with an estimated NPV of US$4,791,243. The NPV of the corresponding alternative investment is US$7,123,380. However, if the tribes were able to secure a zero-interest loan to finance the plant’s installation cost, the project would be on par with the alternative investment. Even if this were the case, the scenario still relies on some of the most optimistic assumptions for the biomass-to-power plant and excludes abatement costs for air emissions. The study thus concludes that at present small-scale, biomass-to-energy projects require a mix of favorable market and local conditions as well as appropriate policy support to make biomass energy projects a cost-competitive source of stable, alternative energy for remote rural tribal communities that can provide greater tribal sovereignty and economic opportunities.

Subject. The article discusses limited sources of energy nowadays and an ongoing survey of new ones. I focus on fuel and energy complexes worldwide and in Russia. Objectives. The study is to analyze the future use of alternative energy sources in the fuel and energy complex nationwide and worldwide. I review the existing energy sources of the fuel and energy complex in the global and regional markets, specifically the alternative ones. Methods. The study relies upon methods of statistics, analysis and systems approach. Results. The article demonstrates that the fuel and energy complex strongly depends on the current situation in the energy resource market, which is difficult to forecast. If we continue relying on traditional energy resources, we get exposed to some risks affecting the sustainable development of the economy. Russia should diversify the power engineering sector by developing alternative energy sources. The article sets forth the economic rationale for alternative sources and key steps Russia shall make. Conclusions and Relevance. Considering the current situation in the energy balance, alternative energy is what any advanced society seeks for, being supported by manufacturers, governmental institutions, and researchers, though low profitability and high infrastructure costs impede its development. In Russia, these challenges are even more palpable. However, even now Russia is able to find alternative energy solutions. In addition to advantages of alternative energy, which is globally proclaimed, they will also help Russia diversify and update the economic system.

Level Of Economic Development

After the first oil-price shock of 1973, a search for new energy policies was started all over the world. Changing one fundamental concept - that relating to the general development of energy supply and consumption - was, however, out of the question. The pre-1973 trend of development was maintained. The energy elasticities did not change. The old forecasts were still held to be valid and were considered now, as earlier, to be the objectives which a successful energy policy had to achieve. This was considered a prerequisite for high growth rates of GNP and improvements in living conditions, and energy consumption was regarded as an indicator of the level of economic development. Therefore, the focus was shifted to an enlargement of the supply of indigenous energy resources as a substitute for imported energy, so that dependence on foreign countries could be minimized.

Statistical Indicators

The article proposes an improved system of statistical indicators for assessing the state and development of the fuel and energy complex of Russia, which defines a methodological approach to identifying factors and trends in its development. The introduction highlights the relevance of modernization of information and methodological support for reaching decisions on new tasks, including those related to the digitalization of the economy and implementation of the national projects’ portfolio. The body of the article critically examines the current configuration of official and departmental statistical information, based on which the authors selected 85 key indicators reflecting the state and development level of the fuel and energy complex of Russia. All of them can be delineated by sectors and analysis tasks. This evaluation system includes 7 blocks: general block characterizing the role of the fuel and energy complex in the economic system; key industry performance indicators; indicators of the production structure by industry; technological indicators of industries; prices for fuel and energy resources; production costs by industry; distribution indicators of fuel and energy resources. The paper analyses development trends in the fuel and energy sectors for 2008-2018. In particular, the authors’ research showed that modern oil production is characterized by a change in the territorial structure, as well as the reinstatement of the role of vertically integrated companies in the development of oil production. The article presents findings on the technological upgrading of Russian oil refining. However, the authors’ research proved that oil refining depth has ceased to be a reliable indicator of the level of technological equipment and modernization level of oil refineries. With regard to the development of the gas industry, there has been a steady increase in gas production, which is supported by maintaining a steady increase in demand for Russian gas in the domestic and foreign markets. The all-time high domestic consumer demand for gas fuel, associated with the Russian Regions Gasification Program implemented by the Ministry of Energy of Russia, was recorded. At the same time, the authors identified the main risk factors in the development of the industry related to Gazprom (a backbone of the energy sector) activities. The persistent positive growth dynamics in commodity production of associated petroleum gas was established. It was also noted that the highest percentage of its beneficial use is characteristic of operators of production sharing agreements. As for the results of the analysis of the coal industry, a matter of interest is the growth of domestic prices for coal products and related derivative trends. Particular attention is paid to the development of the possibilities of using over-the-counter coal price indicators. Replacement of coal with natural gas at a thermal power station in most regions of the country is of interest within the identified development trends of the electric power industry in Russia, which is explained by the environmental friendliness of electricity generation.
