The subsequently described installation steps are demonstrated as shell commands, where the path before the % sign denotes the directory in which the commands following the % should be entered.

Clone the Repository#

First of all, clone the PyPSA-Eur repository using the version control system git in the command line.

/some/other/path % cd /some/path

/some/path % git clone

Install Python Dependencies#

PyPSA-Eur relies on a set of other Python packages to function. We recommend using the package manager mamba to install them and manage your environments. For instructions for your operating system follow the mamba installation guide. You can also use conda equivalently.

The package requirements are curated in the envs/environment.yaml file. The environment can be installed and activated using

.../pypsa-eur % mamba env create -f envs/environment.yaml

.../pypsa-eur % mamba activate pypsa-eur


The equivalent commands for conda would be

.../pypsa-eur % conda env create -f envs/environment.yaml

.../pypsa-eur % conda activate pypsa-eur

Install a Solver#

PyPSA passes the PyPSA-Eur network model to an external solver for performing the optimisation. PyPSA is known to work with the free software

and the non-free, commercial software (for some of which free academic licenses are available)

For installation instructions of these solvers for your operating system, follow the links above. Commercial solvers such as Gurobi and CPLEX currently significantly outperform open-source solvers for large-scale problems, and it might be the case that you can only retrieve solutions by using a commercial solver. Nevertheless, you can still use open-source solvers for smaller problems.


The rules cluster_network and simplify_network solve a mixed-integer quadratic optimisation problem for clustering. The open-source solvers HiGHS, Cbc and GlPK cannot handle this. A fallback to SCIP is implemented in this case, which is included in the standard environment specifications. For an open-source solver setup install in your conda environment on OSX/Linux. To install the default solver Gurobi, run

mamba activate pypsa-eur
mamba install -c gurobi gurobi

Additionally, you need to setup your Gurobi license.

Handling Configuration Files#

PyPSA-Eur has several configuration options that users can specify in a config/config.yaml file. The default configuration config/config.default.yaml is maintained in the repository. More details on the configuration options are in Configuration.

You can also use snakemake to specify another file, e.g. config/config.mymodifications.yaml, to update the settings of the config/config.yaml.

.../pypsa-eur % snakemake -call --configfile config/config.mymodifications.yaml
