The open energy modelling framework

Project Description

Oemof stands for “Open Energy System Modelling Framework” and provides a free, open source and clearly documented toolbox to analyse energy supply systems. It is developed in Python and designed as a framework with a modular structure containing several packages which communicate through well defined interfaces.

With oemof we provide base packages for energy system modelling and optimisation.

Everybody is welcome to use and/or develop oemof. Read our ‘Why should I contribute’ section.

Contribution is already possible on a low level by simply fixing typos in oemof’s documentation or rephrasing sections which are unclear. If you want to support us that way please fork the oemof repository to your own github account and make changes as described in the github guidelines:


Full documentation can be found at readthedocs. Use the project site of readthedocs to choose the version of the documentation. Go to the download page to download different versions and formats (pdf, html, epub) of the documentation.

Installing oemof

If you have a working Python3 environment, use pypi to install the latest oemof version.

pip install oemof

For more details have a look at the ‘Installation and setup’ section. There is also a YouTube tutorial on how to install oemof under Windows.

The packages feedinlib, demandlib and oemof.db have to be installed separately. See section ‘Using oemof’ for more details about all oemof packages.

If you want to use the latest features, you might want to install the developer version. See section ‘Developing oemof’ for more information. The developer version is not recommended for productive use.

Structure of the oemof cosmos

Oemof packages are organised in different levels. The basic oemof interfaces are defined by the core libraries (network). The next level contains libraries that depend on the core libraries but do not provide interfaces to other oemof libraries (solph, outputlib). The third level are libraries that do not depend on any oemof interface and therefore can be used as stand-alone application (demandlib, feedinlib). Together with some other recommended projects (pvlib, windpowerlib) the oemof cosmos provides a wealth of tools to model energy systems. If you want to become part of it, feel free to join us.


The linkage of specific modules of the various packages is called an application (app) and depicts for example a concrete energy system model. You can find a repository with all currently available examples for oemof on github. The examples show optimisations of different energy systems and are supposed to help new users to understand the framework’s structre. There is some elaboration on the examples in the respective repository.

You are welcome to contribute your own examples via a pull request or by sending us an e-mail (see here for contact information).
