For the North and Arctic regions of Russia the task of the small power generation development is important because there are large areas of expensive decentralized electricity supply (DES) and difficult living conditions. In studying the processes of the small energy development, it is important to detail regional features and economic conditions that determine competitiveness of promising types of energy sources. The article presents the analysis results of the DES of the Russia northern territories on the example of three regions: the Republic of Komi, the Arkhangelsk region, the Republic of Sakha (Yakutia). The analysis aim is to determine the existing prerequisites and barriers to active development of the small power generation in the North. On the basis of the detailed energy-economic indicators and the received generalizations, options for improving the efficiency of autonomous energy supply based on conventional and new small-sized power generation technologies are being considered. The analysis showed that the development of DES zones does not have the institutional incentives and sufficient resource base for qualitative technological modernization. Most of the investment and operating costs of DES in the northern regions are compensated through cross-and budget subsidizations. Traditional diesel generation remains high-cost and low-efficiency, its modernization is carried out at slow rate, the potential of electric and heat energy cogeneration is not used. Renewable energy technologies are not ready for large implementation in local energy systems of the North and Arctic 14of Russia. The renewables projects, implemented over the past five years, are mainly experimental and demonstration. The analysis of the indicators of the "northern" renewable energy projects does not confirm their economic efficiency. The reasons are not only in the high unit investment costs, but also in relatively low utilization rates of the installed capacity (capacity factors) of solar and wind power plants. There is no targeted state support for the development of the efficient small-sized power generation in northern regions.

The purpose of the study was the comparative analysis of Russian and foreign practices of alternative energy development at the local level. The object of this research is the set of administrative influences that act as determinants of the formation of generation based on renewable energy as part of sustainable development of local communities and green economy. The subject of study is mechanisms, tools and practices of development of alternative energy. The main methods of research work are general theoretical research methods: analysis and synthesis, as well as methods of measurement, comparison, grouping and graphics. To assess the "gaps" between the current and target status of "green" energy as a set of controlled subsystems, the authors propose a method of GAP analysis, at this the main subsystems are allocated as the share of clean energy in the total volume of its generation, the average share of domestic equipment and components in the composition of power plants for alternative energy, the average level of depreciation of power plants to alternative energy, the average time to receive a construction permission for installations of renewable energy sources and connection to the central power grid. The article analyzed and systematized to-date mechanisms to stimulate the development of alternative energy in municipalities and regional governments in foreign countries. General constraints in the development of alternative power generation are revealed. The differentiation of regions of Russia according to the share of "green" power generation in its total production is made. Practices for effective implementation of infrastructure projects of "green" energy in municipalities of the Russian Federation are described and incentives for alternative energy development at the local level are defined. On the basis of generalization of experience of infrastructure projects in the field of alternative energy in cities and regions of Russia the most significant "barriers" in the development of renewable energy infrastructure at the local level are selected and classified , which include economic, administrative, institutional, technological and climatic ones. Several recommendations for the development of incentives to overcome constraints are formulated.

The possibility of installing photoelectrical solar units inside domical structures with the maintenance of their power generation level was investigated; an optimal distance between a photoelectrical solar unit and the transparent walls of the respective domical structure was determined. The experiments were carried out at the North-Eastern Federal University in the central part of the Republic of Sakha (Yakutia) by determining reduction in the electrical energy efficiency of photoelectrical solar units when changing their location. An optimal distance for installing such units within transparent domical structures was found based on graphical interpretations and gradients. The authors obtained reference parameters for light flux reduction, the generation power of a photoelectrical solar unit when changing the operation medium, and the optimal distance of a photoelectrical solar unit inside a domical structure for reducing the surface contamination of the unit. It was found that, when photoelectrical solar units are operated within a transparent domical structure, the power generation falls by 25.61% as compared to actual results in open space. It was found that an increase in the distance between the transparent walls of the domical structure and the unit led to a decrease in the power generation by ~23.01% and the light flux power by 5.224% at 1.5 m. This method of installing photoelectrical solar units can be used in the construction and designing of smart home systems and autonomous power generation facilities in northern regions of Russia.

In this paper we analyze the impact of the renewable energy sources on the overall electric power system of the Republic of Macedonia. Specifically, the effect of the photovoltaic power plants is examined. For this purpose we developed an electricity production optimization model, based on standard network flow model. The renewable energy sources are included in the model of Macedonia based on hourly meteorological data. Electricity producers that exist in 2012 are included in the base scenario. Two more characteristic years are analyzed, i.e. 2015 and 2020. The electricity producers planned to be constructed in these two years (which include the renewable energy sources) are also included. The results show that the renewable energy sources introduce imbalance in the system when the minimum electricity production is higher than the electricity required by the consumers. But, in these critical situations the production from photovoltaic energy sources is zero, which means that they produce electricity during the peak load, and do not produce when the consumption is at minimum.

This paper mainly concentrates on the energy crisis for a long time in Bangladesh. The government is trying its best to overcome this problem. Due to high investment requirement for conventional power plants, responses from the private sector for power generation are very poor. One alternative solution may be the expanded use of renewable energy. At present solar cells are in use for power generation. But due to high initial investment required for solar panel installation, this form of renewable energy has not been practiced much. The aim behind the study is to integrate the architectural planning regarding physical environment and power crisis problem which may lead to an ultimate improvement of socio economic scenario of the country. In doing so the paper proposes a hypothetical model using biogas as a source of renewable energy by using the rural waste-leading to cash from trash.

The existing power facilities of the Republic of Tatarstan face a number of disadvantages related to the system for recording data on the technical condition of boiler and turbine equipment: manual calculation of the parameters of equipment operation, lack of direct access to complete information on the condition of equipment and, as a result, low efficiency in identifying malfunctions, deviations in the operation of equipment, carrying out repair work. Hence, the need for digitalization of the system for recording data on the technical condition of equipment was formed, in response to which software was developed for automating the data recording system and visualizing the technical parameters of reliability at thermal power plants. This proposal is distinguished by the introduction of digital technologies in the process of recording data on the technical condition of equipment, where for the first time the software includes a method for automatically calculating the technical condition index of boiler units. The results of the work will reduce the likelihood of an emergency state of power plant equipment.

Tiga Nusa is a group of small islands in the southeast of Bali separated by Badung Straits. The group consists of Nusa Penida, Nusa Ceningan and Nusa Lembongan islands. The electricity network of Tiga Nusa is isolated from Bali. Most of the used electrical energy is produced using fossil-based fuel power plants, although the islands have a high potential of natural energy resources. The identified potential of natural energy in the islands include PV electricity generation, wind power electricity generation, as well as electricity from sea waves and currents. Biofuel production from jatropha has also been identified. From this perspective, the islands have huge potential for renewable generation. In fact, many of these resources have been captured and used to generate electricity. For example, wind turbines, solar photovoltaic, and biofuels production facilities have been developed. The projects are built by government or state-owned-enterprises and handed over to local communities. In general, most of the renewable energy pilot projects in Nusa Penida also have experienced problems and many of them are now actually abandoned and require substantial repairs. The central government of the Republic of Indonesia has allocated budget to revitalize these facilities including conducting repairs to many of these plants.
