Electricity – Supply. European Union legislation did not preclude national legislation which provided for the application of a levy on wind turbines designed to produce electricity. Therefore, the Court of Justice of the European Union held that Directive (EC) 2009/28 of the European Parliament and Council, art 4 of Council Directive (EC) 2003/96 and art 1(2) of Council Directive (EC) 2008/118 did not preclude Spanish law which established such a levy.
