2025 ATB Data

Download the 2025 ATB Excel Workbook

Each year, the National Laboratory of the Rockies (NLR) 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, operating 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 Apache Parquet format.
