Article 9 5.

Member States may decide not to apply Articles 6, 7 and 8 of this Directive insofar as their application would obstruct, in law or in fact, the performance of the obligations imposed on electricity undertakings in the general economic interest and insofar as the development of trade would not be affected to such an extent as would be contrary to the interests of the Union. The interests of the Union include, inter alia, competition with regard to customers in accordance with Article 106 TFEU and this Directive.
