This paper is devoted to tracing contemporary perceptions of energy security. Energy security, as a concept started its evolution from a point, where it was identified with secure oil provision for countries, which did not possess energetic resources and were increasingly dependent on oil imports. Gradually, the concept of energy security started to be repeatedly used in the scientific papers, popular press and media and even colloquial language. Energy security has become an argument in making political decisions. Nevertheless, despite the exaggerated attention to energy security, still there is no unanimous agreement on what the concept of energy security means, what facets it embraces and, consequently, how it could be measured and controlled. The paper aims to distinguish the main perceptions of energy security and foresee plausible implications of one or another approach adopted.
The share of natural gas as an efficient resource in the deficient Baltic primary energy balance is and will be significant (power generation, district heating, households, industry, etc.). Therefore, in the paper the risk of gas supply is evaluated and appropriate actions are recommended to assure reliable availability of affordable and sustainable energy in the Baltic States. Macro-region’s base (including supply and transit countries), risk and cost assessments, timely introduction of non-market measures, high cyber security level of information processing and management systems are the components of the security strategy. The extension of Incukalns UGS, interlinked pan-Baltic LNG receiving terminal and upgrade of cross-border trunk pipelines are recommended as the most efficient tools. Complex realization of all instruments and solidarity of the countries are the key issues to implement proposed strategy.
