The European Commission has decided to open formal proceedings with respect to the behaviour of Svenska Kraftnät (SvK), the Swedish electricity Transmission System Operator (TSO), for possible breaches of the EC Treaty´s antitrust rules on abuse of a dominant market position (Article 82). SvK is the state-owned central administrative authority in Sweden commissioned to maintain, operate and develop the national transmission grid for electric power including the state-owned interconnectors. SvK has exclusive rights to provide electricity transmission services in Sweden. The Commission believes that SvK may be abusing its monopoly position as the Swedish monopoly electricity transmission service provider by limiting export transmission capacity on Swedish interconnectors to neighbouring countries and thereby hindering the proper functioning of the Single Market in electricity. The energy sector competition inquiry conclusions of January 2007 (summarised here) have allowed the Commission to gain an in-depth understanding of the energy sector, which is of key importance for the overall competitiveness of the European economy. It has also allowed the Commission to draw conclusions as to where Commission action based on competition law could be appropriate and effective.
