Preparing Networks
##########################################

The preparation process of the PyPSA-Eur energy system model consists of a group of ``snakemake``
rules which are briefly outlined and explained in detail in the sections below:

- :mod:`build_shapes` generates GeoJSON files with shapes of the countries, exclusive economic zones and `NUTS3 <https://en.wikipedia.org/wiki/Nomenclature_of_Territorial_Units_for_Statistics>`_ areas.
- :mod:`build_cutout` prepares smaller weather data portions from `ERA5 <https://www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era5>`_ for cutout ``europe-2013-era5`` and SARAH for cutout ``europe-2013-sarah``.

With these and the externally extracted ENTSO-E online map topology
(``data/entsoegridkit``), it can build a base PyPSA network with the following rules:

- :mod:`base_network` builds and stores the base network with all buses, HVAC lines and HVDC links, while
- :mod:`build_bus_regions` determines `Voronoi cells <https://en.wikipedia.org/wiki/Voronoi_diagram>`_ for all substations.

Then the process continues by calculating conventional power plant capacities, potentials, and per-unit availability time series for variable renewable energy carriers and hydro power plants with the following rules:

- :mod:`build_powerplants` for today's thermal power plant capacities using `powerplantmatching <https://github.com/FRESNA/powerplantmatching>`_ allocating these to the closest substation for each powerplant,
- :mod:`build_renewable_profiles` for the hourly capacity factors and installation potentials constrained by land-use in each substation's Voronoi cell for PV, onshore and offshore wind, and
- :mod:`build_hydro_profile` for the hourly per-unit hydro power availability time series.

The central rule :mod:`add_electricity` then ties all the different data inputs
together into a detailed PyPSA network stored in ``networks/elec.nc``.
