An overview over the most important changes is given below. \\ Further differentiation of demand cases: – – Introduction of summer and winter average demand.

– – Application of uniform risk (peak demand) once on the whole EU (refer- ence), once with limitation to the CEE region and simultaneous average demand in the rest of EU. \\ More detailed implementation of UGS utilization in the model: – – No utilization under avg. daily demand. – – Avg. injection under avg. summer demand. – – Avg. withdrawal under avg. winter demand. – – Last resort supply under Design Case and Uniform Risk Cases. \\ Evolution of Regional N-1 analysis from status quo to a 10-year horizon.

3.2 Bottom-up approach

The GRIPs follow the principle of a bottom-up approach. Compared to the TYNDP which applies a top-down principle, the members of the working group define content, methods, scope and level of details – under consideration of legal require- ments – amongst themselves. As all member companies of the CEE working group are actively operating gas transmission systems, the resulting high degree of exper- tise allows identifying issues leaving space for optimization and further improve- ment, as well as proactive measures for upcoming challenges in a very efficient way. Furthermore, the GRIPs contribute to translate the overall European network design (namely TYNDP) into a more concrete, regional plan for infrastructure evolution.
