The demand for energy in the Republic of Moldova exceeds the domestically available energy resources, so it imports more than 90% of necessary fuels. Studies that are devoted to energy security include the development of the methodology, identification of the relations between the set indicators, interactions between various factors as well as simulation and prediction of crisis situations. The major objective of these studies is to create a mathematical platform for analyzing and monitoring energy security, prevention of threats and risks in the energy sector caused by various internal and external factors. The monitoring of the indicators is carried out based on the annually updated database containing the primary data for calculation of 46 selected indicators. The generalized level of energy security is determined for each year. Flow diagrams for the fuels obtained as a result of the short-term forecast allow making further energy planning to ensure energy security.
