The feasibility of a geothermal-coal hybrid power cycle was studied in comparison to a strictly geothermal and a coal-fired plant in the Chalk Creek area, Chaffee County, Colorado. The geothermal reservoir in this area is postulated to be liquid dominated with a temperature ranging from 150/sup 0/C to 200/sup 0/C (Pearl 1978). The thermal waters are very low in dissolved solids (250mg/l), and, therefore, corrosion problems should be minimal in steam turbines. Development of the geothermal resource in the Chalk Creek area has been limited so far to direct use in greenhouses, swimming pools, and residential space heating. This paper considers the possibility of generating approximately 50 MW of power using the available geothermal energy in a hybrid or geothermal cycle as an alternative to producing electricity from a straight coal-fired plant.
