Science Applications, Inc. (SAI), of La Jolla, California, recently completed a Department of Energy-sponsored contract entitled "Regional Operations Research for Geothermal Energy Resources in California and Hawaii." The study, which was cosponsored by the states of California and Hawaii, involved the preparation of development scenarios for the site-specific geothermal energy utilization. Factors constraining development were identified and recommendations made to accelerate resource utilization. The scenarios were revised iteratively through comment by federal and local government agencies, utilities, and private developers to ensure the maximum level of realism. Finally, a methodology was developed to monitor progress of both direct use applications and electric power generation toward the goals DOE has set for the Pacific Region
