National Legal and Regulatory Framework

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unbundling, ISO, ITO) since it was considered that the legal and operational unbundling foreseen in the previous, repealed Directive 2005/55/EC did not bring satisfying results as per the achievement of the above goal.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.   

L. 4001/2011 was also amended, inter alia, by the following:  

  • Article 17 (13) of L. 4203/2013 (Government Gazette Α’ 235/1.11.2013) and in turn article 2(2) of L. 4336/2015 (Government Gazette Α’ 94/14.8.2015) amended article 73 of L. 4001/2011 concerning security of supply so as to comply with the European Regulation 994/2010. Furthermore, article 17 (12) of L. 4203/2013 amended article 2 (2) of L. 4001/2011 and then MD Δ1/Β/10233/2014 (Government Gazette Β’ 1684/24.06.2014) was issued by the same law further laying down the categories of Protected Natural Gas Consumers.

4. Security of Supply

5. Climate Neutral Economy

The National Energy and Climate Plan formulates Greece’s policy on energy and climate change issues until 2030, taking into consideration the recommendations of the European Commission, as well as the UN goals for Sustainable Development, through the creation of road map with specific quantitative goals, priorities and policy measures for a broad spectrum of economic activities. The initial National Energy & Climate Plan, published in January 2019, foresees by 2030, 31% RES share in gross final energy consumption, 16,5% lignite share in electricity generation, reduction of greenhouse gasses by 32% compared to 1990 and improvement of energy efficiency in final energy consumption by 33%. However, new, more ambitious goals have been according to the ratification decision of the National Energy & Climate Plan (Gov. Gaz. Β’4893/31.12.2019) which foresees by 2030, at least 35% RES share in gross final energy consumption (with an average European target of 32%), 61% RES share participation in final electricity consumption and no lignite participation (delignitization) by 2028), reduction of greenhouse gasses by at least 42% compared to 1990 (in full agreement with the European target) and improvement of energy efficiency in final energy consumption by 38%.

a. Adjustment to Climate Change

Articles 42-45 of L.4414/2016 (Government Gazette A’ 149/9.8.2016) set the processes for creation and the minimum contents of National Strategy for the Adjustment to Climate Change, as well as the by Region Plans for Adjustment to Climate Change (its content was further specified by virtue of Ministerial Decision no. 11258/ Government Gazette B’ 873/16.3.2017). The National Strategy for the Adjustment to Climate Change sets the general goals and the means for the achievement of an effective strategy for the country’s adjustment to the framework set by the UN agreement, the Strategy of the EU and the European Directives for the Adjustment to Climate Change, also taking into consideration international experience. The necessary adjustment measures include a wide range of intervening actions which focus on the rational management of forests and waters, the maintaining of biodiversity, the adjustment of buildings and infrastructures to future extreme climate conditions, the protection of coastal regions from the rise of sea level. The creation of Regional Plans that follow focuses on the setting of ad hoc policy and priorities for measures on the basis of climate conditions and particular characteristics of every region.
