Natural gas transmission networks (from 2011)

Barriers to competition still remain within the internal market in natural gas. This Regulation lays down rules providing a framework for natural gas transmission and trade in order to counteract this dysfunction.


Regulation (EC) No 715/2009 of the European Parliament and of the Council of 13 July 2009 on conditions for access to the natural gas transmission networks and repealing Regulation (EC) No 1775/2005 (Text with EEA relevance).


This Regulation aims at laying down rules for natural gas transmission networks, gas storage and liquefied natural gas (LNG) facilities. It concerns access to infrastructures, particularly by determining the establishment of tariffs (solely for access to networks), services to be offered, allocation of capacity, transparency and balancing of the network.

Certification of transmission system operators

National regulatory authorities shall send the European Commission notification of decisions relating to the certification of a transmission system operator. The Commission then has a period of two months to deliver its opinion to the national regulatory authority. The authority then adopts the final decision concerning the certification of the transmission system operator. This decision and the Commission’s opinion are published.

European Network of Transmission System Operators (ENTSO) for gas

Creation of the ENTSO for Gas

By 3 March 2011, the transmission system operators for gas shall submit to the Commission and to the Agency for the Cooperation of Energy Regulators the draft statutes for the ENTSO for Gas, a list of members and draft rules of procedure.

Tasks of the ENTSO for Gas concerning network codes

The Commission shall consult the Agency for the Cooperation of Energy Regulators and the ENTSO for Gas in order to establish an annual list of the priorities which are to contribute to developing network codes. These codes shall be developed using a non-binding framework guideline submitted to the Commission by the Agency. The codes include rules and procedures relating in particular to:

  • network security and reliability;
  • data interchange;
  • technical and operational exchanges;
  • transparency rules;
  • harmonised transmission tariff structures;
  • energy efficiency.

Tasks of the ENTSO for Gas

The ENTSO for Gas is responsible for adopting:

  • common network operation tools;
  • a ten-year network development plan;
  • recommendations relating to the coordination of technical cooperation between Community transmission system operators;
  • an annual work programme;
  • an annual report;
  • annual summer and winter supply outlooks.

Costs and tariffs

The regulatory authorities shall determine tariffs or methodologies for their calculation. Member States may take decisions relating to tariffs such as fixing auction arrangements.

Third-party access services

Transmission system operators shall offer their services equitably to all network users on a rolling basis in the long and short term.

LNG and storage facility operators must also offer their services according to the procedure described above and make them compatible with the use of interconnected gas transport networks.

Allocation of capacity and congestion management

All market participants must have access to maximum network capacity as well as storage and LNG facilities.

Infrastructure operators shall implement and publish non-discriminatory and transparent congestion-management procedures which facilitate cross-border exchanges in gas on a non-discriminatory basis.

This Regulation repeals Regulation (EC) No 1775/2005 as from 3 March 2011.


The 2002 and 2003 European Gas Regulatory Forums (the Madrid Forums) were at the origin of guidelines on best practice. However, experience acquired has demonstrated that these guidelines should be made legally enforceable. This Regulation is based on the guidelines in order to strengthen the internal market in natural gas.

Official Journal

Regulation (EC) No 715/2009



OJ L211 of 14.8.2009


Commission Regulation (EU) No 984/2013 establishing a Network Code on Capacity Allocation Mechanisms in Gas Transmission Systems and supplementing Regulation (EC) No 715/2009 of the European Parliament and of the Council (OJ L 273 of 15.10.2013). A more transparent, efficient and non-discriminatory system of allocation of scarce transmission capacities needs to be implemented for the Union’s high-pressure gas grids, so that there is greater cross-border competition and market integration. This Regulation aims to establish the necessary degree of harmonisation across Europe introducing tariff systems to ensure the implementation without detrimental effect on the revenues and cash flow positions of transmission system operators.

Commission Regulation (EU) No 312/2014 establishing a Network Code on Gas Balancing of Transmission Networks (OJ L 91 of 27.3.2014). To move towards greater market integration, it is important that rules on gas balancing of transmission networks facilitate gas trading across balancing zones thus contributing towards the development of market liquidity. This Regulation sets out harmonised EU-wide rules on balancing the objective of which is to give network users the certainty that they can manage their balance positions in different balancing zones throughout the EU in an economically efficient and non-discriminatory manner.
