2021 Annual Technology Baseline (ATB) Cost and Performance Data for Electricity Generation Technologies

Published by National Renewable Energy Laboratory (NREL) | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-01-02T20:03:05Z
Starting in 2015 NREL has presented the Annual Technology Baseline (ATB) in an Excel workbook that contains detailed cost and performance data, both current and projected, for renewable and conventional technologies. The workbook includes a spreadsheet for each technology. This version of the workbook provides the final updates to data for the 2021 ATB. In 2019 and 2020, NREL has also provided selected data in Tableau workbooks and structured summary csv files. The data for 2015 - 2020 is located on https://data.nrel.gov. In 2021 and going forward, the data is cloud optimized and provided in the OEDI data lake. A website documents this and future data at https://atb.nrel.gov.
