New Database for Costs of Energy Technologies

07/23/2012 |

As part of the Energy Department’s Open Energy Information platform (, the Department has released a public database featuring cost and performance estimates for electric generation, advanced vehicle, and renewable fuel technologies.

The Transparent Cost Database (TCDB) provides technology cost estimates that can be used to benchmark company costs, model energy scenarios, and inform research and development decisions.

Users can view a range of estimates for what energy technologies – such as a utility-scale wind turbine, rooftop solar installation, biofuel production plant, or an electric vehicle – might cost today or in the future.

The cost data are sourced from published studies and projected cost targets and performance estimates developed by DOE. Despite being public, this information was previously difficult to find and collect. The database currently contains thousands of estimates from more than 100 reports.
