The European Commission confirmed on 13 February 2007 that it carried out unannounced inspections at the premises of several producers of power transformers, which constitute key components in electricity transmission and distribution networks. The Commission was assisted by officials from the national competition authorities in France, Germany and Austria. The Commission suspects that the producers concerned may have engaged in a violation of Article 81 EC. The inspection presents a first step in the Commission's investigation and indicates the existence of a suspicion but does not prejudice the outcome.
