Ethanol: a brief economic evaluation
Del Rio Farms, Inc. has a large farm in the Imperial Valley area of California, a known geothermal resource area. The 10 MW geothermal flash steam power plant, operated by Union Oil Company, is located on their property. Presently the owners have under consideration a 10 million gallon per year ethanol plant. The initial feed to the plant would be corn, with sugar beets as a possible alternate feed. The ultimate plan is to use waste products and biomass feed stocks. Geothermal water would provide the necessary process heat for the plant. An economic evaluation was performed to assist in the planning. Each of the following conclusions are based on an ethanol plant that produces 10 million gallons of ethanol per year. Over a 20 year period, the plant using a corn feed stock would generate a rate of return of +12% on a total equity capital investment of $33,000,000. Over a 15 year period, the plant using a corn feed stock is probably not economically feasible since it would have a rate of return less than 12% or a total equity capital investment of $33,000,000. A corn feed stock plant operates at a loss for the first seven years if 95% of the $33,000,000 cost is debt financed. The plant is economically feasible only if offsetting energy income from other profitable operation permits taking advantage of investment tax credits and depletion allowances that are available. If this is true, the project is highly feasible, paying back twice the 5% equity capital in the first year.
