The Portuguese Presidency's Progress Report on the Internal Market Package was adopted on 3 December 2007 by the Energy Council. The report indicates that a significant number of EU Member States agree that ownership unbundling is necessary, although some States are still unconvinced. The report also indicates that all Member States agree that unbundling rules should be similar to avoid distortions between Member States in the internal market. The Commission welcomed this significant step and other important progress made in relation to other issues raised in the package. These include the powers and independence of national regulators and the need for a mechanism to improve the coordination of national energy regulators.
