In this paper, the recommendations of the ENTSO-E Expert Panel regarding the grid incident on the Iberian Peninsula are compared to the German Grid Code requirements and the conformity assessment procedure. The comparison shows that several recommendations are already reflected in the German technical connection rules, particularly regarding the technical capabilities of generating units and their verification during planning and commissioning. However, the analysis also identifies areas for further development, especially concerning recurring verification during operation, data availability, existing units and restoration-related requirements. Drawing from these results, FGH presents an ongoing research project on automated compliance testing during the operational phase of power plants and discusses how automated testing infrastructure could support both certification processes and ongoing operational monitoring.
