Figure shows the specific capital cost of a 10 MW e surface power plant as a function of the geofluid (i.e. water) production temperature. This capital cost is converted to a surface-plant-only LCOE using three different sets of financing assumptions (Table ): LAZARD, LIKELY, and O&M-Only. The reservoir depth necessary to obtain the given geofluid production temperature is shown below the x-axis, assuming a geologic temperature gradient of 35 °C/km and a 15°C surface temperature. Lastly, the specific capital cost of an EGS surface plant reported by Sanyal (2007) 39 is plotted.
