The dissertation is devoted to the deepening of theoretical positions, the improvement of methodological approaches and the provision of practical recommendations on measures to improve the economic security of enterprises of the agro-industrial complex in terms of its energy component. The essence of economic security in the context of sustainable development is defined. It has been determined that economic security is the basis for sustainable development as one that does not provide for negative impact on society and the environment. Given that energy affects all three components of sustainable development (economy, ecology, society), its role in ensuring economic security is also important. The influence of the unstable functioning of the energy component on the economic security of enterprises behind individual components is considered. It has been determined that the energy component affects the financial (loss of benefits, loss of productivity and revenues, technological pauses that incur additional costs, etc.); technological (accidents, equipment failure, urgent rebuilding of the technological process, etc.) components. It is proposed to consider the management of energy supply not only as a technical process, but also as a management process, which is based on the basic functions of management. Based on this, the definition of the concept of "energy management" is proposed - this is the process of planning energy consumption, searching for alternative sources of energy supply or energy resources, organizing energy supply by signing relevant contracts with suppliers, motivating employees to reduce energy consumption and controlling the process of energy supply and its consumption. Approaches to assessing the level of economic security of enterprises are systematized and developed, the specifics of financial and economic activities of small and medium enterprises are determined, and on their basis requirements for conducting an assessment for such business entities are formulated, a composition of indicators is proposed for assessing the level of economic security energy security indicator at the micro level. A conceptual scheme for managing the economic security of small and medium-sized enterprises has been proposed, which takes into account the organizational and economic features of their operation and provides for the possibility of conducting a rapid analysis of the economic security of such enterprises, which can significantly reduce financial, time and personnel costs.
