2023 ATB Data

Download the 2023 ATB Excel Workbook

Each year, the NREL ATB data are presented in an Excel workbook that contains detailed cost and performance data (both current and projected) for renewable and conventional technologies. The workbook contains a spreadsheet with data and calculations for each technology. 

Download the 2023 ATB Summary CSV Files

These CSV files summarize in database-friendly form the capital expenditures, operations expenditures, and capacity factor, as well as the financial assumptions and the levelized cost of energy, for each technology. They are reformatted from the summary section of the spreadsheet, which documents the underlying calculations and data. The same data are also available in the Apache Parquet format.

The charts on the ATB website were developed in a set of Tableau workbooks. These 19 workbooks are available as a single zip file. You can download a single workbook by following the instructions below to download a PowerPoint, but click on Tableau Workbook in the download menu.
