The NREL Annual Technology Baseline (ATB) provides a consistent set of technology cost and performance data for energy analysis. And the ATB electricity data is freely available.

To inform electric sector analysis in the United States, each year NREL provides a robust set of modeling input assumptions for energy technologies (the Annual Technology Baseline) and a diverse set of potential electricity generation futures or modeling scenarios (Standard Scenarios).

The ATB is a populated framework to identify technology-specific cost and performance parameters or other investment decision metrics across a range of fuel price conditions as well as site-specific conditions for electric generation technologies at present and with projections through 2050.



The ATB, which is supported by the Office of Energy Efficiency & Renewable Energy, Office of Strategic Programs and Impact Analysis, leverages and continues significant activity funded by the U.S. Department of Energy (DOE) and EERE for individual technologies and market segments.
