Evaluation and Ranking of Geothermal Resources for Electrical Generation or Electrical Offset in Idaho, Montana, Oregon and Washington. Executive Summary.
The objective was to consolidate and evaluate all geologic, environmental, legal, and institutional information in existing records and files, and to apply a uniform methodology to the evaluation and ranking of all known geothermal sites. This data base would enhance the making of credible forecasts of the supply of geothermal energy which could be available in the region over a 20 year planning horizon. The four states, working under a cooperative agreement, identified a total of 1265 potential geothermal sites. The 1265 sites were screened to eliminate those with little or no chance of providing either electrical generation and/or electrical offset. Two hundred and forty-five of the original 1265 sites were determined to warrant further study. On the basis of a developability index, 78 high temperature sites and 120 direct utilization sites were identified as having ''good'' or ''average'' potential for development and should be studied in detail. On the basis of cost, at least 29 of the high temperature sites appear to be technically capable of supporting a minimum total of at least 1000 MW of electrical generation which could be competitive with the busbar cost of conventional thermal generating technologies. Sixty direct utilization sites have a minimum total energy potential of 900+ MW and can be expected to provide substantial amounts of electrical offset at or below present conventional energy prices. Five direct utilization sites and eight high temperature sites were identified with both high development and economic potential. An additional 27 sites were shown to have superior economic characteristics, but development problems. 14 refs., 15 figs., 10 tabs.
