European Network of Transmission System Operators for Gas


The European Network of Transmission System Operators for Gas is an association of Europe's transmission system operators. ENTSOG was created on 1 December 2009 by 31 TSOs from 21 European countries. Creation of the ENTSOG was initiated by the adoption of the European Union third legislative package on the gas and electricity markets. It aims to promote the completion and cross-border trade for gas on the European internal market, and development of the European natural gas transmission network. According to the third energy package ENTSOG is required to develop an EU-wide ten-year gas network development plan.
