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.

🚀 Quickstart

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

⌨️ Usage

Please note that PyPSA-AT is only supported on Linux platforms. Installations on Windows or macOS require
modifications that are currently not supported.

Prerequisites

Git and pixi must be installed.

Installation

Configure your model by adjusting the base scenario in config/config.at.yaml
Include scenario settings that differ from the base scenario in config/scenarios.manual.yaml
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 at_all
```

📖 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.
