Potential impact of R and D on hydrothermal energy cost

The potentital impact of the DOE/Geothermal Technology Development programs on the cost of geothermal power has been estimated using the computer program IMGEO.300. Results indicate a potential 30 to 40% cost reduction for hydrothermal systems with a 40 to 50% cost reduction potential for binary systems. The purpose of this document is to demonstrate the use of IMGEO. The initial results are tentative because the R and D goals have not been finalized and the code has not been completely validated
