Energy security is considered as one of the most important challenge for world countries, given that it represents one of the main pillars of sovereignty. This study aims to evaluate and analyse the energy security performance of Algeria over the period 1980-2020 through the development of a composite index, named ESIA, on the basis of five dimensions; Availability, Affordability, Applicability, Acceptability and Governance. The results show that energy security presents a moderate performance, with score range of (5.29-7.51). The highest performance is showed during the sub-period 2005-2020. The availability, affordability and applicability indicators are the main drivers of this performance, respectively. While, the acceptability indicators play a little positive effect, and the proactive nature of energy sector governance is still considered as challenging for Algeria. Five important policy implications were identified in order to improve the energy security of the country.
