The modern electric power industry dates back to the 1970s, when all electric power enterprises belonged to the state, and the development of branches of the national economy was of a directive nature. After the collapse of the Soviet Union, the power industry was transferred to the government corporation RAO UES of Russia, which ceased to exist on July 1, 2008 in accordance with the logic of the reform. To date, private companies have emerged in the industry, which began to build their strategy and corporate governance differently. The article is dedicated to the issues of sustainable development of the electric power industry of the Russian Federation; special attention is paid to the social sphere of activity of the electric power industry organizations. The work analyzed the dynamics of changes in the total number of employees, of employees hired and departed, of jobs created and terminated, the average monthly nominal wage in the industry, as well as the number of employees employed in harmful labor conditions. Further, based on the data of energy companies that were transferred to private management after the reform of the electric power industry in 2008, an analysis of sustainable development in the social sphere of the country's five largest electric power companies was carried out according to the indicator system developed by the authors. The work also presents a set of indicators reflecting the level of social development of an organization in accordance with its directions, which can be used in the system of social controlling. At the end of the article, an attempt was made to create a system of indicators of social sustainability assessment based on a group of factors reflecting employee satisfaction and social security.
