National Legal and Regulatory Framework test

Primary Legislation

The import, trade (supply), transmission and distribution of natural gas in Greece were initially regulated by L. 2364/1995 (Government Gazette Α’ 252/6.12.1995).

Subsequently, in order to comply with the obligations regarding the liberalization of the natural gas market which were imposed by the 2nd Energy Package of the European Union regarding the common set of rules of the internal gas market (Directive 2003/55/EC and ΕC Reg. 1775/2005), L. 3428/2005 (Government Gazette Α’ 313/27.12.2005)on “The Liberalization of the Natural Gas Market“ was issued, which integrated into national legislation the aforementioned provisions of the European Directives and Regulations.

Following the issuance of the 3rd energy package and in order to comply with its provisions (specifically, Directive 2009/73/EC and the EC Regulations 713/2009 & 715/2009), with the ultimate goal the further smooth completion of the internal natural gas market and the creation of equal access terms for all natural gas companies within the EU, the new energy law L. 4001/2011 (Government Gazette Α’ 179/22.8.2011) for the operation of Energy Markets for Electricity and Natural Gas was enacted, which replaced in its majority L. 3428/2005. Directive 2009/73/EC introduced the unbundling of the networks from the supply and generation activities with the adoption of three alternative models (ownership unbundling, ISO, ITO) since it was considered that the legal and operational unbundling foreseen in the previous, repealed Directive 2005/55/EC did not bring satisfying results as per the achievement of the above goal.  L. 4001/2011 initially provided only for the adoption of Ownership Unbundling.The Legislative Act of 16.12.2011 (Government Gazette Α’ 262/16.12.2011), foresaw the possibility of enactment of the Independent Transmission Operator model (ΙΤΟ) for the Transmission Systems owned by a Vertically Integrated Company on September 3rd 2009, as well as the option to choose, for the Vertically Integrated Companies wishing to do so, the Ownership Unbundling Model. The provisions of Law 4001/2011 regarding the Independent Transmission Operator were amended with L.4093/2012 (Government Gazette Α’ 222/12.11.2012), Legislative Act Government Gazette Α’229/19.11.12 and L.4111/2013 (Government Gazette Α’ 18/25.01.2013).

The abovementioned new provisions also include details concerning the implementation of the respective legal and functional unbundling.
