When the Baltic Sea region is included in debates concerning European energy policy, the focus often lies on the transit of natural gas. However, this focus on gas transit is too narrow to fully grasp the region as a wider element within the complex fabric of the European energy system. This article therefore approaches the energy system of the Baltic Sea region in a holistic manner and discusses flows of natural gas, oil, coal, and electricity. Against this backdrop, the article presents and discusses the energy supply and demand situation of the Baltic Sea littoral states. Focussing strictly on the Baltic Sea region in a narrow geographical sense allows a detailed visualisation of energy flows between individual countries. From a geoeconomic perspective, the article then analyses and compares the positions of Germany and Poland in the regional energy system; furthermore, scenarios concerning the effect of Polish and German national energy policies on regional energy flows are presented and discussed. As most European countries are energy importers, this discussion focuses on the effect of national policies on energy imports and their impact on the regional energy system. Based on this discussion, the article evaluates the geoeconomic implications of these scenarios for Poland and Germany and the prospects for better aligning the two countries’ national energy policies.
