The European Commission has initiated proceedings against the German energy group E.ON and the French gas company Gaz de France in relation to suspected market sharing. In particular, the allegations concern supplies of natural gas transported over the MEGAL pipeline which is jointly owned by E.ON and Gaz de France. The initiation of proceedings against E.ON and Gaz de France arises from information obtained during the inspection carried out by the Commission in May 2006. The alleged infringements, which are thought to have been an attempt by the companies? to protect their home markets, will be investigated in depth in the course of the proceedings.
