The System Development Map 2020 / 2021 presents existing gas infrastructure and capacity information for 2021. Data presented in the capacity matrix were obtained from the ENTSOG Transmission Capacity Map 2021 and ENTSOG Transparency Platform, adapted and approved by gas TSOs on 1 December 2021.

The 2020 / 2021 historical data on gas demand and supply are presented aggregated in the form of charts (using data during summer 2020 and winter 2020/2021 to allow the analysis of gas storage usage) – these data are available in the ENTSOG Summer and Winter Outlook Review Reports.

Information regarding the gas storage fill rate was obtained from GIE AGSI+.

The Country Profiles include demand data that represent actual country demand for the days/periods shown, storage and LNG capacities according to the interconnection to the country’s transmission system, and installed gas-fired power generation capacity (additional data sources: GSE 2021 Storage Map (including necessary updates), GLE 2019 LNG Map and ENTSO-E Transparency Platform). The gas production data reflects the maximum deliverability achieved. All data provided in the map are for information purposes, should be treated as indicative only, and should not be used for commercial purposes.

The map series aims at providing a compact and regular overview of existing gas infrastructure and outlook for its development as well as of actual supply and demand situation at both the European and national level from the perspective of a respective year. It aims at establishing an easy reference for such information and at mapping trends and their development over time. As such it contributes to enhanced transparency of the gas market.
