Gazprom’s Nord Stream 2 and diffuse authority in the EU: managing authority challenges regarding Russian gas supplies through the Baltic Sea

ENThis article addresses a neglected question about the effects of dispersed authority in the European Union (EU) on the EU’s ability to manage external contestations. It investigates authority challenges from two major external actors in the energy, and specifically the gas sector, and scrutinizes the management of authority conflicts at local sites in different EU states in the Baltic Sea region. The second Russian transboundary submarine gas infrastructure project Nord Stream 2 (NS2), owned and managed by a wholeowned subsidiary of the Russian state-controlled energy giant Gazprom, serves as an illustrative case study. It reveals how multiple authority conflicts at different sites and levels, and the challenges from both the Russian Federation (Russia) and the United States of America (USA), played out, and why formal adjudication has been a primary tool for the EU and several of its member states to assert their authority and manage contestations at the local, national and EU level.
