The potential for the development of a small-scale hydropower in the decentralised area of the Republic of Sakha (Yakutia): A case study of the Indigirka river basin

Бесплатный доступ

The energy potential of small northern rivers of Yakutia has not been utilized and actively studied so far. But due to the gradual increase in demand for electricity and the growing annual costs of providing northern imports to hard-to-reach areas of Yakutia, the issue of using small rivers as a source of energy has gained relevance. The simplicity of small hydropower allows it to operate both autonomously and as part of a centralised power system. This approach is especially advantageous in the northern regions of the republic, where the combination of small hydropower in summer and the centralized power system in winter will optimize fuel costs. This paper considers the possibility of utilizing the potential hydropower resources of the Indigirka basin. The assessment of potential hydropower resources of the In-digirka basin was carried out for the mountainous section, which can be explained by its physiographic and altitudinal conditions. The mountainous part of the basin is characterized by the largest reserves of hydropower resources. The lower reaches of the Indigirka demonstrate extremely weak energy indicators. The potential power of rivers 50 km long and more was determined using the linear method. The study did not consider the energy of watercourses with lengths of less than 10 to 50 km.
