ASSESSMENT OF ELECTRICAL LOADS OF POTENTIAL PROJECTS FOR THE DEVELOPMENT OF MINERAL RESOURCES IN THE EASTERN REGIONS OF THE ARCTIC ZONE OF THE RUSSIAN FEDERATION

The paper presents estimates of the electricity demand and electrical loads of potential projects for the development of mineral resources in the Arctic zones of the Krasnoyarsk Territory, the Republic of Sakha (Yakutia) and the Chukotka Autonomous Region. The focus is on the priority projects characterized by a high degree of exploration of mineral resources, and the availability of mining licenses, feasibility studies or business plans. The study indicates that the limiting factor for the implementation of the projects is the inaccessibility of sites and underdevelopment of the transport and energy infrastructure in the eastern Arctic zone of the Russian Federation. During the research, we employ the standard method for assessing electricity consumption, taking into account the raw material extraction and processing technologies under the Arctic conditions. The required generating capacity in the implementation of the projects under consideration can reach 425 MW in 2025 and increase to 826 MW by 2035 with the electric power production of 6 billion kWh. The largest increase in electricity consumption is expected in the Taimyr-Turukhansky key zone during the development of rare-earth deposits — Chernogorsk and Norilsk-1, as well as the Suzun, Tagul and Lodochnoye oil and gas fields of the Vankor area. The project for the development of the Peshchanka copper deposit in the Chukotka key zone is comparable to these projects in terms of electrical loads. The power supply of planned production facilities for the implementation of these pro­jects will require the development of generating capacities and the grid infrastructure of the functioning energy centers in the eastern Arctic zone: Norilsk, Vankor, Chaun-Bilibinsk. Smaller projects, especially on the territory of the North-Yakutsk key zone, can focus only on autonomous power supply. At the same time, fuel extraction projects will focus on own resources for energy supply of local production facilities. In addition, to ensure the effectiveness of projects for the development of metal ore deposits, the problem arises of choosing feasible options for the fuel supply of autonomous power plants.
