The purpose of this paper is to document and review existing national gas emergency plans in the European Union, following the guidelines and requirements set out by the EU's Regulation 994/2010 concerning measures to safeguard security of gas supply. Despite the great deal of attention paid to questions of natural gas security in an increasingly import-dependent European Union, the contingency plans of most of its member states have not been widely published or scrutinized. By reviewing TSO network codes and national legal and regulatory acts, this paper teases out the key similarities and differences between member states' emergency planning frameworks, tools and methods. A gas emergency operational template is subsequently proposed that conforms to EU legislation. This is followed by a discussion of emergency planning in the context of regional cooperation and the liberalizing European gas market. The paper concludes by advocating gas emergency measures which are proportionate to the crisis level, sensitive to the gas demand profile, aware of the regional context, inconsequential to normal market operation, transparent and non-discriminatory during implementation and verifiable during emergencies as well as under normal conditions.
