Abstract
We have investigated the economics of geothermal feedwater heating (GFWH) in a steam Rankine cycle with base capacity of 583 MW (gross). The capital cost per kW geothermal power (before geofluid pumping) is compared with those of stand-alone geothermal plants of equal power. The economic benefits of GFWH over stand-alone plants for enhanced geothermal systems are, in order of importance:
