Evaluation of the Effects of Geothermal Reservoir Fluid Temperature on the Costs of Steam Production and Power Generation

This report provides a preliminary evaluation of the effect of reservoir temperatures on the cost of geothermal hot water wells and flash-steam gathering systems to support a 50,000 kW power plant. Comparisons are made of the capital investments required for each case and the corresponding payout period based on steam costs of 6 mill/kWh of power generated. In order to show how the reservoir temperatures and steam cost affect the cost of electric power delivered to the high tension bus at the power plant, capital costs estimates were prepared and economic analyses made to determine the cost of electric power for each corresponding case
