ENTSOG brings together Europe’s gas Transmission System Operators (TSOs) to strengthen cross‑border cooperation and support a secure, efficient and integrated energy system in line with EU energy and climate goals.

Originally, ENTSOG’s regulatory tasks were defined under Gas Regulation (EC) No 715/2009 and included developing network codes and guidelines for market and system operation, elaborating the Ten-Year Network Development Plan (TYNDP), providing regular information on gas supply and demand for the European market, and delivering common operational tools to ensure network security and reliability.

In recent years, ENTSOG’s scope has evolved to reflect Europe’s energy transition and security-of-supply priorities. Under Regulation (EU) 2024/1789, the activities fall within the EU framework for renewable gas, natural gas and hydrogen markets. ENTSOG supports the development and evolution of European network codes and guidelines. It also monitors their implementation and market effects, and provides tools and data that enhance interoperability, transparency and system reliability.

ENTSOG also contributes to joint scenario work with ENTSO‑E, including through the TYNDP process. In addition, ENTSOG supports security-of-supply coordination through the ReCo System for Gas and engagement with the Gas Coordination Group. Finally, ENTSOG supports the integration of renewable and low‑carbon gases via monitoring and reporting (including the Gas Quality Monitoring Report), alongside strengthened data exchange and cybersecurity practices.
