ENTSOG South-North Corridor GRIP 2017 - Main Report

8.3.1 MARKET CONVERSION PROJECTS L- TO H-GAS in the GASPOOL Market Area The complete conversion of the German gas transmission system from L-gas to H-gas is planned for 2030 as set out in the draft German NDP 2016. For this rea- son Gasunie Deutschland developed a project called ‘GUD: Complete conversion to H-gas (TRA-N-955)‘ to show in several steps the implementation of the GUD L-gas transmission system in H-gas until 2030. The project is linked to the GTS project ‘H-Gas conversion of L-Gas export border point (TRA-N-882)’. On the German side no investments are required, the pre-existing infrastructure will be used. The project is only a capacity modification, which does not require actual investment or construction works. The project ‘Embedding CS Folmhusen in H-Gas (TRA-N-951)’, which is also related to the conversion of the German gas transmission system from L-gas to H-gas, ensures the operability of the Compressor Station Folmhusen in the H-gas system (so far this can only accommodate L-gas). 8.3.2 MARKET CONVERSION PROJECTS L- TO H-GAS in the NCG Market Area Including the ZEELINK Project In order to handle the declining L-gas production of the Groningen field, the German TSOs Open Grid Europe and Thyssengas are planning the development of several new metering and regulating stations connecting H-gas transmission system with the current L-gas transmission systems in line with the draft German NDP 2016. In addition, Open Grid Europe and Thyssengas are currently developing the 227km ZEELINK project from the Belgian-German cross-border interconnection point Lichtenbusch via Sankt Hubert to Legden (North Rhine-Westphalia). The ZEELINK project includes a new 39MW compressor station near Aachen. The ZEELINK project represents the largest single project in the German Network Development Plan 2016. It connects new H-gas sources to the German gas trans- mission system (e. g. the LNG-terminal Zeebrugge in Belgium), reinforces the North- South transmission capacity in the NCG market area and thereby contributes to the security of supply in the NCG market area including the regions affected by the L-gas production decline. Technical Capacities from/to Gas Storages and to DSO Systems The following system enhancement projects aimed at increasing the technical capacities between the TSO and DSO systems as well as between the TSO systems and gas storages in the NCG market area are included in the draft German NDP 2016 and the TYNDP 2017. \\ New 33MW Wertingen compressor station by bayernets and Open Grid Europe (TRA-N-340) \\ New 39MW Rimpar compressor station project by GRTgaz Deutschland and Open Grid Europe (TRA-N-755) \\ New 45MW Rothenstadt compressor station by GRTgaz Deutschland and Open Grid Europe (TRA-F-337) 8.3.3 NCG MARKET AREA TSO PROJECTS – \\ New 39MW Herbstein compressor station by Open Grid Europe (TRA-F-344) \\ 49MW upgrade of the Werne compressor station by Open Grid Europe (TRA-F-345) \\ Schwandorf to Finsing pipeline (141km) project by Open Grid Europe (TRA-F-343) These system enhancement projects are aimed at increasing the technical capaci- ties between the TSO systems and gas storages in the NCG market area as well as capacities from the TSO to the DSO systems in the NCG market area.
