Members

Since its foundation, ENTSOG Member TSOs have provided wide coverage of the European gas market. In addition, ENTSOG's Articles of Association were modified in December 2010 to admit TSOs from EU countries currently derogated from the Third Energy Package as Associated Partners. This allowed for participation in ENTSOG activities.

In February 2011, TSOs from Third Party countries (candidates for EU accession, members of the Energy Community or EFTA) interested in following development of the network codes were also admitted to the Association as Observers. Following Brexit and in accordance with the established EU-UK Trade and Cooperation Agreement, UK TSOs are no longer ENTSOG Members as of 1 January 2022.

ENTSOG was created on 1 December 2009 and is now comprised of:

43 TSO Members, 1 Associated Partner and 9 Observers.
