United States Geothermal Supply Curves 2024

Published by National Renewable Energy Laboratory | Department of Energy | Catalog Last Checked: April 25, 2026 at 08:43 AM | Dataset Last Updated: April 15, 2026 at 10:37 PM
This data packet contains supply curves and a composite siting exclusion TIFF for EGS and hydrothermal geothermal across the contiguous United States. The supply curves offer comprehensive metrics such as capacity (MW), generation (MWh), levelized cost of energy (LCOE), levelized cost of transmission (LCOT), and more for each reV site. The composite exclusion TIFF is a single file that delineates areas where geothermal installations are permissible based on various siting assumptions. This data packet contains information for a single scenario across four depths and two technologies (enhanced geothermal systems and hydrothermal).
