PyPSA-Eur is an open model dataset of the European power system at the transmission network level that covers the full ENTSO-E area. The software pipeline to assemble the model is developed at https://github.com/PyPSA/PyPSA-eur and documentation is available at pypsa-eur.readthedocs.io. This repository provides pre-built PyPSA networks resulting from corresponding PyPSA-Eur Releases using the default configuration! The model alternating current lines at and above 220 kV voltage level and all high voltage direct current lines, substations, an open database of conventional power plants, time series for electrical demand and variable renewable generator availability, and geographic potentials for the expansion of wind and solar power.
