Transparent Cost Database
The Transparent Cost Database collects program cost and performance estimates for U.S. DOE EERE technologies in a public forum where they can be viewed and compared to other published estimates. The database includes literature on technology cost and performance estimates (both current and future projections) for vehicles, biofuels, and electricity generation. All data are downloadable for full transparency.
This project is under active development and we welcome user suggestions for additional features or modifications to enhance usability for the energy community. The database also allows nomination of datasets for inclusion in the database or comments on the estimates used by interested users. Please to report a problem with the Transparent Cost Database, to post a comment, and to nominate additional datasets.

The data gathered here are for informational purposes only. Inclusion of a report in the database does not represent approval of the estimates by DOE or NREL.
Levelized cost calculations DO NOT represent real world market conditions. The calculation uses a single discount rate in order to compare technology costs only.
