The post Second World War years were marked by a pressing need for a common approach in energy issues. This took form in the creation of the European Coal and Steel Community in 1951. Also, the establishment of the Energy Community is an expression of this need. In 2005, after years of turbulences, the Western Balkan region and the European Union agreed to work together towards one common goal.
In 2009, the Ministerial Council took a decision on the first enlargement of the Energy Community. With the accession of Moldova and Ukraine, the geographical reference of Western Balkan became obsolete. As of Feb 2011, the Treaty rather aims at implementating EU energy policy in non-EU countries.
