European energy markets are undergoing rapid and fundamental change. Last year alone the Council and Parliament adopted the second energy liberalisation package, including the new electricity and gas Directives and the electricity Regulation. In addition, the Commission tabled new Directives on Security of Supply and a draft gas Regulation. This is affecting markets not only in the European Union, but throughout Europe, the Mediterranean, the Balkans and Russia. These changes have affected not only energy law. Community competition law in the energy sector has been evolving quickly, reacting to the restructuring of the markets, and the new commercial partnerships that result.
