Archived Releases

Past releases of the U.S. Energy Policy Simulator can be downloaded from the releases section of Energy Innovation's U.S. EPS GitHub repository. The compressed "Source code" file below each release is the complete model package, including the Vensim model files, input data, and Python scripts. (Note that to run the model, you will need to install Vensim Model Reader. For help, see the instructions on the Download page.)

For non-U.S. versions of the Energy Policy Simulator, go to the list of Energy Innovation's GitHub repositories, select the repository for the region of interest, and navigate to its "releases" section (on the "code" tab).

Many changes, including bug fixes, have been made with each model version. See the Version History section of the model documentation page for details. We recommend using only the most recent version of the EPS for analysis purposes. However, older versions of the EPS may be useful for comparing the performance of different EPS releases or replicating results obtained via an older EPS release.
