This page lists energy models published under open source licenses. We regard licenses approved by OSI (opensource.org) and The Open Definition (opendefinition.org) as suitable for open source models and open data, respectively. Please contact us if you are using another license and wish to be added. Models which have not yet been made public, but which intend to do so under a suitable license, can also be included here.
Currently, the models listed classify exclusively as bottom-up, but that is not a restriction we impose. Some models are confined to the electricity sector while others also traverse the heat, gas, end-use, and mobility sectors. Some embed market clearing while others assume single-actor cost minimization. The model attributes shown below should help to clarify the type of model.
Most models listed here count as frameworks in which any region can be modelled. Region-specific implementations of the frameworks are listed on a separate page by region Open model implementations.
After logging in, you can add new entries to the model database by entering the name of the system into the following form field:
