City of El Centro geothermal energy utility core field experiment. Final report, February 16, 1979-November 30, 1984

Description: The City of El Centro was awarded a contract in late 1978 to cost share the development of a low to moderate temperature geothermal resource in the City. The resource would be utilized to heat, cool and provide hot water to the nearby Community Center. In December 1981, Thermal 1 (injector) was drilled to 3970 feet. In January 1982, Thermal 2 (producer) was drilled to 8510 feet. Before testing began, fill migrated into both wells. Both wells were cleaned out. A pump was installed in the producer, but migration of fill again into the injector precluded injection of produced fluid. A short term production test was undertaken and results analyzed. Based upon the analysis, DOE decided that the well was not useful for commercial production due to a low flow rate, the potential problems of continued sanding and gasing, and the requirement to lower the pump setting depth and the associated costs of pumping. There was no commercial user found to take over the wells. Therefore, the wells were plugged and abandoned. The site was restored to its original condition.

Engineering and economic feasibility of utilizing geothermal heat from the Heber reservoir for industrial processing purposes at Valley Nitrogen Producers Inc. , El Centro agricultural chemical plant. Final report

Description: The engineering and economic feasibility of utilizing geothermal heat from the Heber KGRA for industrial processing purposes at the Valley Nitrogen Producers, Inc. El Centro, California agricultural chemical plant was investigated. The analysis proceeds through the preliminary economics to determine the restraints imposed by geothermal modification size on internal rates of return, and through the energy utilization evaluation to determine the best method for substituting geothermal energy for existing fossil fuel energy. Finally, several geothermal utilization schemes were analyzed for detailed cost-benefit evaluation. An economically viable plan for implementing geothermal energy in the VNP Plant was identified and the final conclusions and recommendations were made based on these detailed cost-benefit analyses. Costs associated with geothermal energy production and implementation were formulated utilizing a modified Battelle Pacific Northwest Laboratories' ''GEOCOST'' program.

The Baca Data Dissmination Program

Description: The goal of the federal government's coordinated program of research and development in geothermal energy is to stimulate the economic, reliable, operationally safe, and environmentally and socially acceptable commercial development of this energy resource. This commercialization plan is based on the premise that developers, utilities, and the financial community will not make large-scale commitments to unfamiliar technology until confidence is gained from the commercial-scale demonstration of this technology. The primary objective of the Baca Geothermal Demonstration Power Plant Project, therefore, is to provide that confidence through a first-of-a-kind commercial-scale fifty-megawatt demonstration of the production of electric power from a liquid-dominated hydrothermal resource in the United States.

Multi-purpose utilization of hydrothermal resources within the City of El Centro. Final report

Description: The engineering and economic feasibility of utilizing geothermal heat from the Heber KGRA for space heating/cooling and water heating for domestic and industrial process applications within the City of El Centro was investigated. The analysis proceeds through an engineering survey of present conventional energy utilization within the City to identify and evaluate those end uses which could potentially utilize geothermal heat as a substitute for fossil fuel or electrically produced heating and cooling. A general engineering and economic evaluation of heat and cold delivery alternatives followed including evaluations of geothermal fluid transmission options, alternative refrigeration techniques, heat and cold transmission media options, probable systems interfaces, materials evaluations, projected conventional energy costs, life cycle costs for existing conventional systems, projected pricing requirements for privately and municipally developed geothermal resources, the relative distribution costs of heat delivery options, and estimated residential and commercial retrofit costs. A cost-effective plan for large-scale utilization of geothermal energy in El Centro for district heating/cooling and industrial applications was developed from this evaluation and preliminary conclusions drawn. Institutional barriers and environmental impacts associated with geothermal development in the City were also evaluated. Potentially adverse impacts were identified along with mitigating measures that should either completely eliminate or reduce these adverse effects to levels of insignificance.

Commercial production of ethanol in the San Luis Valley, Colorado. Final Report

Description: The purpose of this study is to assess the commercial feasibility of producing between 76 and 189 million liters (20 and 50 million gallons) of ethanol annually in the San Luis Valley, Colorado using geothermal energy as the primary heat source. The San Luis Valley is located in south-central Colorado. The valley is a high basin situated approximately 2316 meters (7600 feet) above sea level which contains numerous warm water wells and springs. A known geothermal resource area (KGRA) is located in the east-central area of the valley. The main industry in the valley is agriculture, while the main industry in the surrounding mountains is lumber. Both of these industries can provide feedstock for the production of ethanol.

The San Luis Valley is located in south-central Colorado. The valley is a high basin situated approximately 2316 meters (7600 feet) above sea level which contains numerous warm water wells and springs. A known geothermal resource area (IGRA) is located in the east-central area of the valley. The main industry in the valley is agriculture, while the main industry in the surrounding mountains is lumber. Both of these industries can provide feedstocks for the production of ethanol.
