Russian generating companies in the power industry require a certain transformation of corporate governance to reduce the investment risks associated with today’s challenges in order to increase investment attractiveness. For this purpose, the paper examines the rotation of ownership in these companies, the updated methodology of the Bank of Russia for assessing corporate governance, including in the context of the ESG agenda, HR strategy and growing digitalization. The results of a general assessment of the corporate governance of generating companies are presented; an additional analysis of the compliance of companies with the criteria for each of the sections of the Russian Corporate Governance Code was carried out; a comparative analysis of the structural characteristics of the boards of directors of Russian generating companies and foreign companies that are similar in terms of concentration of ownership (Germany) and the presence of the state in it (France) was carried out; the article presents the results of the assessment of internal documents. The generalization of the obtained data makes it possible to formulate proposals for further transformations of corporate governance in generating companies in the face of modern challenges, including new corporate governance standards with a certain set of additional compliance criteria, reorganization of boards of directors by updating the structural characteristics of the board, as well as the composition and content of internal documents.
