The EC has requested that Spain withdraw the conditions imposed by the Spanish energy regulator (CNE) on the acquisition of the energy group Endesa by the Italian electricity incumbent Enel and the Spanish conglomerate Acciona. The transaction was unconditionally cleared by the EC. However, CNE imposed several conditions on the buyers including the requirement to maintain Endesa’s decision-making centre in Spain. The EC ordered Spain to withdraw these conditions after finding that they violated its exclusive merger control jurisdiction. If Spain fails to comply the EC is likely to start proceedings before the European Court of Justice (ECJ). The ECJ has previously found that Spain violated EU law by imposing similar conditions on the attempted acquisition of Endesa by the German group E.ON and by enacting legislation that enabled CNE to review and approve acquisitions of regulated energy companies.
