This dataset is a qualitative assessment of geothermal potential (Enhanced Geothermal System EGS) for the US based on Levelized Cost of Electricity, with CLASS 1 being most favorable, and CLASS 5 being least favorable. This dataset does not include shallow EGS resources located near hydrothermal sites or USGS assessment of undiscovered hydrothermal resources. The source data for deep EGS includes temperature at depth from 3 to 10 km provided by Southern Methodist University Geothermal Laboratory (Blackwell & Richards, 2009) and analyses (for regions with temperatures equal to or greater than 150°C) performed by NREL (2009). CLASS 999 regions have temperatures less than 150°C at 10 km depth and were not assessed for deep EGS potential. Temperature at depth data for deep EGS in Alaska and Hawaii not available.
This layer represents the relative geothermal potential by county boundary within the contiguous US. This boundary file, current as of 2012, was specifically designed for large scale thematic mapping.
