The economic production of electrical power from high temperature steam and liquid dominated geothermal resources has been demonstrated. Large quantities of geothermal energy are considered to exist at moderate temperatures, however, the economics of converting this energy into electricity has not been established. This paper presents the design concept of a dual boiler isobutane cycle selected for use with the moderate temperature hydrothermal resource and presents a cost estimate for a 10 and 50 MW power plant. Cost of electrical power from these plants is estimated and compared with that from coal, oil and nuclear plants. The impact of selling a portion of the residual heat in the geothermal effluent is assessed. (auth)
