The paper presents a study of the influence of uncertainties in the thermophysical properties of the working fluids on the preliminary design and sizing of the major components of a power plant. The effect of these uncertainties is discussed first qualitatively to characterize the nature of the problems resulting from them, then quantitatively to determine the relative magnitude of the differences in component design and size that would result if a power plant is designed on the basis of different sets of working fluid properties. Special emphasis is placed on isobutane which appears to be attractive for geothermal energy extraction.
