The subject of research presented in this paper is development and application of methodologies for managing technical risks in the complex power facilities. The vulnerabilities (threats), the uncertainties and faults of the power facilities and its' equipment, as well as the interruptions in the power system are analyzed. The main objective is defining an convenient methodology for providing the opportunity for analysis and providing acceptable reliability of the technical system, i.e. reducing the number of interruptions to a minimum, optimizing the utilization of the available potential and ensuring safe working procedures. According to the methodology and necessary analyzes, risk management is realized by setting margins that determine the acceptability of risk exposure and reducing the likelihood of occurrence of events that have a potential threat to reduce the reliability of the systems. Furthermore, the methodology of a fault tree and a log events for quantitative risk assessment in the power plants will be applied, as well as the use of the Baes networks for decision making for the treatment of the technical risks. As a result, it is expected that risk management techniques will enable successful management of the risks, faults and activities associated with the identified risks in order to ensure safe and reliable functioning of the plants and facilities as a whole. An overview is given to the operation of the protection and management systems that often reach a high level of specificity as they are affected by the equipment or the characteristics of the plants (substations, power plants, lines) and it is necessary that experts who know the process study them well. In addition, companies that have specific expertise need to quantify and accurately represent them. These risks have economic impact on the performance of companies and therefore their assessment and risk management is of highest necessity.
