Transparency Guidelines

The energy market liberalisation process, aimed at securing a genuine, well-functioning, open and efficient internal market in gas, has significantly changed the gas transmission business and increased the need for transparency. In this respect, specific obligations for gas TSOs have been introduced through Regulation (EC) No 715/2009, which defines the basic transparency rules, further specified in Chapter 3 of Annex I (and its amendments).

The network codes have been developed to provide rules and procedures to reach an appropriate level of harmonisation towards efficient gas trading and transport across gas transmission systems in the EU, increasing data publication requirements.

The objective of the Transparency Activities in ENTSOG is to enhance the transparency of gas TSOs’ activities in the European Union. This is realised by the data published on the Transparency Platform and the TSOs’ websites. The requirements for the transparency publications are specified in Reg. (EC) 715/2009 and the Network Codes.

Regulation (EU) No 1227/2011 and its Commission Implementing Regulation (EU) No 1348/2014 introduced additional publication and reporting obligations to the market participants, aimed at supporting market monitoring, fostering open and fair competition in wholesale energy markets. These obligations are also dealt with in the Transparency Area in ENTSOG.

The English version of the most recent version of the Reg (EC) 715/2009 is available here.
