Our membership in organizations


    European Network of Transmission System Operators for Gas (ENTSOG) was established in 2009 following the adoption of the so called third energy package. The main purpose of ENTSOG is to promote the completion and functioning of the internal market in natural gas and cross-border trade and to ensure the optimal management, coordinated operation and sound technical evolution of the natural gas transmission network.

    Specific tasks of the organisation arise from the Regulation 715/2009 on conditions for access to the natural gas transmission networks. They most important responsibilities of ENTSOG embrace the drafting of network codes in the areas defined by the Regulation 715/2009. ENTSOG is also responsible for the development of the EU-wide Ten-Year Network Development Plans (TYNDP), Gas Regional Investment Plans (GRIP), supply outlooks and operational tools.
