Prior work created Geothermal Electricity Evaluation Model (GETEM) and GEOthermal energy for the Production of Heat and Electricity ("IR") Economically Simulated (GEOPHIRES), which have played a pioneering role in techno-economic geothermal resource assessment. For example, GEOPHIRES was developed out of the MIT-EGS model, which was used for technoeconomic assessments of EGS geothermal power plants starting in the 1980s. Further, GETEM supply curves also are the default cost and capacity relationships used to define geothermal power plants within which are all energy systems models that can be used to inform policy decisions. Recently, GETEM was used to create U.S.-wide supply curves for all hydrothermal and EGS geothermal power plants in the 2019 U.S. DOE GeoVision report. Despite this reputability, neither GETEM nor GEOPHIRES were generalizable enough to be applied for this study because they fundamentally rely on characterizations of results from unpublished ASPEN simulations to estimate electricity generation and cost. This reliance limits the applicability of these tools to any power plants besides traditional indirect power plants that use water as the subsurface heat extraction fluid. In contrast, the generalizability of genGEO means that nearly any geothermal energy system may be investigated, including sedimentary basin power plants that use CO 2 as the subsurface heat extraction fluid.
