Data outputs from optimisation of Wind+Hydrogen+Other+Battery+Solar (WHOBS) electricity systems for European countries. Input data and code can be found here: https://github.com/PyPSA/WHOBS The summary of the results with metadata can be found here: https://github.com/PyPSA/WHOBS/tree/master/results-181002 if you don't want to download 6 GB. To load the data, install PyPSA and do e.g. for Germany (DE) in 2030: network = pypsa.Network("DE-2030.nc") Note that in these files, in some hours batteries discharge and charge at the same time. This is because the model wants to dump energy and this behaviour has the same cost and effect as curtailing wind and solar. In the latest version of the github code, wind and solar have tiny marginal costs (0.02 and 0.01 EUR/MWh respectively) to prevent this behaviour. With these costs, curtailment is preferred.
