The U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) has released a 2019 update to the Annual Technology Baseline (ATB), a key source of reliable electricity generation technology cost and performance data used to support and inform electric sector analysis in the United States. Now in its fifth year, the ATB documents technology-specific information on a broad spectrum of electricity-generation technologies—including wind, solar, geothermal, hydropower, biopower, coal, natural gas, and nuclear—as well as battery energy storage.
Geothermal technology cost and performance projections have been updated with analysis and results from the GeoVision: Harnessing the Heat Beneath our Feet report (DOE, 2019). The GeoVision report is a collaborative multiyear effort with contributors from industry, academia, national laboratories, and federal agencies. The analysis in the report updates resource potential estimates as well as current and projected capital and O&M costs based on rigorous, bottom-up modeling.
