The geologic reservoir model provides two important values to the coupled geothermal power plant model of genGEO: 1) the reservoir impedance (Section S7.1), and 2) geofluid production temperature entering the production well (Section S7.2). The reservoir impedance is the reservoir's resistance to flow and is essential to determining the overall flowrate of the system. The surface plant electricity generation is very dependent on the geofluid production temperature as the heat-to-electricity conversion efficiency (i.e. thermal efficiency) is proportional to production temperature.
