Abstract: Geothermal resource assessment requires several input parameters at a time when field information is normally very limited. The power plant efficiency is an important parameter as it affects investment cost and profit. However, there is significant debate in the geothermal industry on the appropriate performance measure to implement. In this paper we attempt to determine the best performance measures for financial decision making during the exploration stage of geothermal power developments. We compare and contrast current performance measures commonly used by the geothermal industry. This includes thermal efficiency, geothermal brine effectiveness, utilisation efficiency and enthalpy efficiency.
