Security of Supply
After the gas crises of 2006 and 2009, the EU reinforced its security of gas supply notably by adopting the first security of gas supply Regulation No 994/2010 in 2010. On 28 October 2017 revised Regulation No. (EU) 2017/1938 concerning measures to safeguard the security of gas supply and repealing Regulation (EU) No 994/2010 entered into force. This security of gas supply Regulation was amended by Regulation (EU) 2022/1032 with regard to gas storage. In a broader context, Council Regulation 2022/2578 (Enhancing Solidarity) and Council Regulation 2022/2578 (Market Correction Mechanism) were also created to enhance security of supply in Europe.
With the entry into force of Regulation (EU) 2024/1789, the Regulation (EU) 2017/1938 is also replaced and these changes apply from 1 January 2025.
The new rules ensure a regionally coordinated and common approach when choosing the security of supply measures among EU Member States. The regulation also defines the role of ENTSOG in ensuring the security of gas supply. ENTSOG has also been tasked to take part in the works of the Gas Coordination Group (GCG) and ensure functionality of the Regional Coordination System for Gas (ReCo System for Gas).

Outlooks & Reviews
Summer Supply Outlook assess the ability of the European gas infrastructures to provide flexibility while enabling shippers to fill storage in preparation of the winter. Winter Supply Outlook assesses both the possible evolution of UGS inventory along different winter cases as well as the resilience of the European gas infrastructures under peak conditions. These reports assess the level of service provided by infrastructures considering the latest trends in supply and demand and does not intend to forecast market behaviour. ENTSOG delivers on a voluntary basis the Summer and Winter Review reports: a description of the behaviour of the gas market during the upcoming summer and winter season on the basis of the observed daily gas flows and prices.
Security of Supply Simulation
Article 7 of Regulation (EU) 2017/1938 stipulates that by 1 November 2017 ENTSOG carry out a Union-wide simulation of gas supply and infrastructure disruption scenarios. This report identified and assessed emergency gas supply corridors and identified which Member States can address identified risks, including in relation to LNG. The gas supply and infrastructure disruption scenarios and the methodology for the simulation were defined by ENTSOG in cooperation with the GCG. The Union-wide simulation of gas supply and infrastructure disruption scenarios are repeated every four years unless circumstances warrant more frequent updates.
ReCo System for Gas
ENTSOG has also been tasked to take part in the works of the Gas Coordination Group and ensure functionality of the Regional Coordination System for Gas (ReCo System for Gas). ENTSOG ensures facilitation of the existing ReCo System for Gas as a CNOT for emergency conditions, including a common incidents classification scale, and other supporting documentation for the ReCo Teams. ENTSOG continues to facilitate knowledge sharing amongst TSOs regarding operational procedures in emergency conditions.
