Title:	Construction of the new Forbach pumped storage plant / Neubau des Pumpspeicherwerks Forbach
Abstract:	The Rudolf-Fettweis hydropower plant, owned and operated by EnBW Energie Baden-Württemberg AG, is situated in the Murg valley in the Northern Black Forest. The construction of a new underground Lower Basin is planned to upgrade the existing hydropower station. The in-situ rock mass consists of Forbach Granite with local weakness zones, as encountered in the boreholes. Considering the extent of the project area, a 3D geological prediction model was used to allow a better interpretation of the spatial relationships of weakness zones in the rock mass and to optimize the orientation of the underground caverns. Adverse effects for the public were counteracted at a very early stage, so that the project received a high level of public acceptance. The present paper describes the current state of the project. Im Murgtal im Nordschwarzwald befindet sich das Rudolf-Fettweis-Werk der EnBW Energie Baden-Württemberg AG. Zur Erneuerung des Standorts ist der Neubau einer untertägigen Unterstufe geplant. Die im Projekt angetroffenen geologischen Verhältnisse bestehen aus der Formation des Forbach-Granits, in dem lokale Schwächezonen erkundet wurden. Angesicht der Ausdehnung des Projektgebiets kam ein 3D-Prognosemodell der Geologie zum Einsatz, um die Interpretation der räumlichen Lagebeziehung der Schwächezonen im Gebirge und die Orientierungen der neuen unterirdischen Anlagen entsprechend zu optimieren. Der Vermeidung öffentlicher Betroffenheiten wurde frühzeitig entgegengewirkt, sodass das Projekt eine ausgesprochen hohe Akzeptanz in der Öffentlichkeit genießt. Der vorliegende Beitrag stellt den aktuellen Stand im Projekt vor.
