In the article the influence of cold climate and the causes of failures and emergency modes of operation in the electric power system operating in the territory of the Republic of Sakha (Yakutia) are considered. Reliability and durability of power facilities, including overhead power transmission lines in the conditions of the North, directly depends on taking into account the engineering-geological, climatic and geocryological conditions of the area of their construction. Thus, in the regions of the Far North, under the influence of complex engineering-geological, climatic and geocryological conditions, there are regular disruptions in the operation of existing power transmission lines, which negatively affects the reliability of power supply, especially in winter.
