To understand the financial situation, a program for economic evaluation was developed. This software (Euronaut) is completely modularized and considers all cash flows. Projects like an EGS are wrapped into tree-like structures. Based on the results which were gained at Soultz-sous-Forêts, two configurations were designed. The first EGS configuration consists of a simplified two well (doublet) system where the dependencies of all components (mainly the reservoir, wells, pumps and the heat-to-power conversion unit) are physically and economically linked together. The realization of these dependencies and their complex interactions enable a sensitivity analysis of the borehole depth and reservoir depth, respectively. As a result, depth dependent effective costs and revenues of an EGS plant with the geohydrological characteristics of Soultz-sous-Forêts are determined. As a future development, the second configuration will adapt the actual situation at Soultz-sous-Forêts with the individual features of all four wells (GPK1 – GPK4). Then, this model can be used for all kinds of sensitivity analyses to clarify the impact of certain components or to optimize the operation scheme; e.g. the flow rates. date: 2010 date_type: published publication: Comptes Rendus Geoscience volume: 342 number: 7-8 publisher: Elsevier pagerange: 626-635 id_number: doi:10.1016/j.crte.2009.10.010 issn: 1631-0713 official_url: http://doi.org/10.1016/j.crte.2009.10.010 access_IS-EPOS: limited owner: Publisher citation: Heidinger, Philipp (2010) Integral modeling and financial impact of the geothermal situation and power plant at Soultz-sous-Forêts.
