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.

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 is also available in the Apache Parquet format.
