Between Amity, Enmity and Europeanisation: EU Energy Security Policy and the Example of Bulgaria's Russian Energy Dependence

Considering the development of the Bulgarian energy security strategy this article analyses how the country has adapted to EU membership and to energy security challenges, such as disruptions to Russian gas supplies in 2006 and 2009 and rising gas prices. Utilising a conceptual lens which synthesises Regional Security Complex Theory and Europeanisation, the article offers an explanation of energy policy changes. It concludes that conceptions of Russia as an energy security guarantor have changed since Bulgaria's EU accession and that Bulgarian energy policy has undergone a qualified reorientation away from a positive dependence on Russian energy sources, towards a convergence with EU priorities of diversification and a single energy market.
