The research focuses on improving the process of energy risk management within organizational energy management systems. This improvement enhances the reliability of calculations used to determine the level of energy loss risk by identifying the frequency and severity of the influence exerted by groups of hazardous external and internal factors on total energy losses. To assess the level of risk associated with the identified hazards, threats, or nonconformities based on cause-and-effect relationships and considering the effect of hazardous factors, the BOWTIE method was applied. An eleven-step process for managing energy risks is proposed, which consists of two blocks: energy risk analysis and improvement of its management. The first block includes procedures for defining the characteristics of the infrastructure and parameters of electrical network equipment; identification of hazards, hazardous factors, hazardous events, and their consequences; determination and analysis of the energy risk level, as well as its evaluation. The second block includes the development of measures to reduce energy risks, conducting audits of the energy risk management process, analysis of the results of the energy management system audit and development of proposals for improving energy risk management. The distinguishing feature of the proposed energy risk management process is the need to build a model of cause-and-effect relationships among various hazards that lead to energy losses, hazardous factors that increase the probability of energy losses, hazardous events, and possible consequences of their occurrence. The model of cause-and-effect relationships between hazards, hazardous factors, and hazardous events allows for providing high-quality expert assessments regarding the determination of the frequency of manifestation of the hazardous factor and the severity of consequences from its impact. The scientific novelty of the study lies in identifying the regularity of total energy loss risk formation in energy management systems as the sum of individual risks of energy losses arising from each external or internal hazardous factor. The practical value of the research involves identifying the criteria for acceptability and unacceptability of energy risk levels and developing new criteria for energy risk assessment, which differ from the existing methods by introducing three distinct energy risk levels. They are as follows: acceptable energy risk, which involves established monitoring and additional control operations; acceptable risk subject to verification, which requires mandatory control operations, with further steps allowed only after obtaining positive verification results; unacceptable energy risk, which necessitates the elimination of energy hazards or reduction of the risk level to at least the “acceptable energy risk with verification” category.
