The article assesses the current state and problems of the power supply system, highlights the most pressing problems in the public utilities sector in the Arctic zone of the Republic of Sakha (Yakutia). On the basis of statistical processing of information by subdivisions of JSC Sakhaenergo, the authors present an analysis of the structure of generating capacities and the dynamics of the installed capacity of power plants, including those based on renewable energy sources. Diesel power plants account for the largest share of the installed capacity, with renewable energy sources accounting for less than 1.4%. The main problem in power generation is equipment wear. In total, in the Arctic uluses of the republic in the communal and household sector, the standard resource for operating time since the start of operation exceeded more than 30% of the total number and 20% of the total installed capacity of diesel units, of which 60% are operating after major repairs. The authors outline main problems of fuel supply for the considered Arctic uluses: harsh climatic conditions, difficult transport accessibility, unstable hydrological situation, insufficient amount of dredging work, and a shortage of special road equipment. The assessment of the wear of power transmission lines and transformer substations is carried out. Of the total length of overhead power lines, 18.5% exceed the service life limit. For cable lines, this figure is 50.6%. In five uluses, more than half of the installed capacity of transformers exceeds the standard resource. Assessment of the electricity losses level shows that, on average, they amount to 15% for district power grids. In a number of Arctic uluses, there are high energy losses in power grids as well as their constant growth. When replacing and reconstructing outdated infrastructure, it is advisable to implement measures aimed at reducing losses and increasing the capacity of lines.

Coal Supply

The article considers various options for providing gold mining enterprises in the Arctic zone of the Republic of Sakha (Yakutia) with fuel and energy resources to generate electricity for industrial needs. The authors assess the possibility of organizing the power supply for the operation of the mines using the resources of local coal deposits. The Soginsky brown coal and Krasnorechensk coal deposits are most suitable for mining. The research proves that the use of coal in generation can reduce the cost of power supply in the development of ore and placer deposits. They determined that the lowest unit cost of electricity generation is achieved when brown coal from the Kularski deposit is used as fuel (9.3 rub/kW·h). The use of coals from the Soginsky deposit is 20% more expensive than the Kularsky coals, but the quality characteristics of the coal and the readiness of the deposit for mining are significantly better. The most accessible, but more expensive option for organizing the supply of coal to gold deposits is the use of imported coal of the required quality. The authors outline the necessity of additional appraisal of coal resource potential of the Arctic zone of Yakutia on the base of contemporary economic criteria. There is a need to clarify the extent of coal production and to determine the importance of coal in investment projects in the northeast of Arctic zone of Yakutia.

The author of the paper analyzes the prospects for the poverty level reduction in the Republic of Sakha (Yakutia) and its Arctic regions in terms of achieving the national development goals of the Russian Fed-eration by 2030. On the basis of official statistics and data from open sources, the factors and the downside risks to the socio-economic situation of the people of the region are assessed. The paper considers measures poverty reduction, provided for in the “Strategy for the socio-economic develop-ment of the Arctic zone of the Republic of Sakha (Yakutia) for the period until 2035”. The conclusion is made about the limited effectiveness of such methods of improvement in this area as a social contract, stimulation of self-employment and em-ployment in traditional economic sectors and a low feasibility of a twofold decrease in the poverty level in the Arctic zone of the Republic by 2030. The pos-sibility of achieving this goal exists only if there are system changes in the socio-economic sphere and the comprehensive effort at all levels of government. The importance of an equal distribution of income for the accelerated reduction of the number of citi-zens, who are unable to meet the social and general-ly accepted standards in society owing to a lack of money, is noted.

t. Theoretical approaches to the sustainable development of cities and towns in the Arctic zone of the Russian Federation are considered. As such approaches, the concept of a «green» smart city, the concept of thermal stress in an Arctic city, the concept of a «winter city», the concept of an Arctic base city, the concept of developing coastal Arctic settlements based on the principles of the blue economy (the economy of marine nature management and coastal zones), the concept of ensuring the vital activity of Arctic cities, etc. are analyzed. In addition, the contribution of Arctic cities to environmental pollution and climate change, socio-economic and demographic development of the Arctic zone is analyzed. The development of Arctic cities, especially single-industry towns and settlements is considered in the context of the Republic of Karelia, the Murmansk, Arkhangelsk Regions, the Komi Republic, the Chukotka Autonomous Okrug, the Republic of Sakha (Yakutia) and the Krasnoyarsk Territory. The main directions of sustainable development of Arctic cities and towns are substantiated from the point of view of achieving the target indicators of the “Strategy for the development of the Arctic zone of the Russian Federation and ensuring national security for the period up to 2035”.
