Geothermal Electricity Technology Evaluation Model

The Geothermal Electricity Technology Evaluation Model (GETEM) aids the Geothermal Technologies Office in understanding the performance and the cost of the technologies it is seeking to improve. It is a detailed model of the estimated performance and costs of currently available U.S. geothermal power systems. GETEM can be used to analyze and evaluate currently available technologies and to estimate the cost of certain technologies five to 20 years in the future, given the direction of potential RD&D projects. The model is intended to help GTO determine which proposed RD&D programs and projects might offer the most improvements for the taxpayer dollar.

Download GETEM—Beta Version

This site allows access to the current beta version of GETEM available in an Excel spreadsheet format. This version focuses on the use of an enhanced geothermal resource with an air-cooled binary generation plant. This beta version has not been subjected to any rigorous check or validation; there is no final version of the model available.

Do not use the model without accessing the GETEM manuals and revision notes. The model requires that Solver is installed in Excel. After downloading and running GETEM, view the instructions for determining if Solver is installed and installing it, if it isn't.

Download the GETEM tool.

Notification

This model and its documentation were prepared as required work under a subcontract from the National Renewable Energy Laboratory, a U.S. DOE national laboratory, to Princeton Energy Resources International, Rockville, Maryland. The estimates and correlations for the performance and costs of geothermal electric power systems are intended for use in analysis of government policies, and should not be construed or represented as "official U.S. DOE estimates of performance and/or cost of any real geothermal power system or any of its components."

Further, neither the United States Government nor any agency thereof, nor any of their employees, makes any warranty, express or implied, or assumes any legal liability or responsibility for the accuracy, completeness, or usefulness of any information, apparatus, product, or process disclosed, or represents that its usefulness would not infringe privately owned rights.
