The fulfilment of basic human physical and social needs in a modern world depends on electricity usage and energy-powered systems. This includes electricity for cooking, food and drink preservation, IOT applications in smart homes, transportation and telecommunications. Thus threats on energy supply disruptions can become an everyday concern for an individual; this background justified the nowadays growing interest in energy resilience in the arenas of both scientists and policy planners. Moreover, there is a lack of information available specifically on the municipal level in turn suggesting to move towards the definition of schemes or guidelines for municipalities aiming to reach concrete measure in enhancing energy resilience. This paper is a literature review on the topic of energy resilience specifically addressed to the overall electrical infrastructural system. The authors pay particular attention to selection of various and relevant information sources in order to identify trends and gaps in research within the proposed subject in the last decade. For this reason, an analysis of existing research on municipal and country levels is carried out. More than 6000 scientific articles were used and about 90 were analyzed in-depth in order to create consistent trends based on a specific literature review methodological approach.
