The German long-distance network operators are serving a significant contribution to the security of energy supply by their tailor made expanded and highly available infrastructure for natural gas. Therefor the German long-distance network operators are compiling regularly the grid development plan for the national transport grid (NEP). The NEP is published, consulted, and submitted to the Bundesnetzagentur. The Bundesnetzagentur endorses the grid development plan, and therewith the proposed technical measures are mandatory for the grid operators.
Within the grid development plan the gas flows in the German networks are modelled for the coming next 10 years to determine the expansion respectively the potential investments in the German networks. Basis for this modelling is the scenario framework that is likewise to the grid development plan consulted publically with market participants and endorsed by the Bundesnetzagentur.
