PyPSA-AT: A Sector-Coupled Open Optimisation Model of the Austrian Energy System

[!WARNING]
PyPSA-AT is under very active early development. Expect things to change rapidly.

PyPSA-AT is an Austrian adaptation of the open European energy system
model PyPSA-Eur.
It provides a detailed sector-coupled model of the Austrian energy system, including the majority of relevant energy
carriers (electricity, gas, hydrogen, biomass, heat, coal, oil, methanol and ammonia) and demand profiles for the
industry, transport, residential, commercial, and agriculture sectors.

The project builds upon the methodologies developed in PyPSA-DE - the adaptation of
PyPSA-Eur for the German energy system - while incorporating Austria-specific network topology, energy system
characteristics, and regulatory frameworks.

For more comprehensive documentation on the underlying PyPSA-Eur/DE framework, model decisions, and implementation
details, please refer to the PyPSA-Eur documentation
and PyPSA-DE documentation, respectively.

[!WARNING]
This repository is the official source of PyPSA-AT. Third party forks are independent projects and we do not vouch for their accuracy, methodology, or claims.


🚀 Installation

Running PyPSA-AT is very simple. Just clone the repository

git clone https://github.com/AGGM-AG/pypsa-at.git && cd pypsa-at

And start the workflow (low time resolution and NUTS3 spatial resolution for Austria)

pixi run workflow

Please note that PyPSA-AT is only supported on Linux platforms. Installations on Windows or macOS require
modifications that are currently currently out of scope.

Prerequisites

Git and pixi must be installed.

⌨️ Usage

  1. Configure your model by adjusting the base scenario in config/config.at.yaml

  2. Include scenario settings that differ from the base scenario in config/scenarios.manual.yaml

  3. Run the model’s Snakemake workflow:

    pixi run workflow
    

    or activate the virtual environment and call the same workflow using a shorthand

    pixi shell && snakemake -call all_at

📖 Documentation

More detailed documentation of PyPSA-AT is hosted on pypsa-at.readthedocs.io.

✨ Features

PyPSA-AT extends PyPSA-Eur and PyPSA-DE with Austria-specific network data, regulatory constraints, and energy
system pathways. The full change history is in
CHANGELOG.AT.md; implementation details are in the
documentation.

🤝 Contributing

[!NOTE]
The development team focuses on establishing a well-calibrated representation of the Austrian energy system and
has limited capacity to review contributions from the community at the moment.

In general, please install the pre-commit hooks if you plan to contribute to this project.
