Auxiliary Euro-Calliope datasets: Spatial data to represent a European energy system model at several spatial resolutions

Main output generated with the custom-region possibility-for-electricity-autarky workflow. This output provides similar data to https://doi.org/10.5281/zenodo.3246302 (technically eligible land area for renewables and other spatially disaggregated energy system data), but with two key differences: The spatial extent has been expanded to include Iceland. Two new spatial resolutions have been added: ehighways and ehighways_disaggregated. ehighways defines 98 regions based on the result of work undertaken in the European Commission Seventh Framework Programme project e-HIGHWAY 2050 [1]. The regions cover 35 European countries; 19 are described at a national resolution and the rest at a subnational resolution. Those at a subnational resolution are aggregated from NUTS3-2006 statistical units. ehighways_disaggregated provides the data at the resolution of statistical units in Europe, which is then aggregated to produce the data at the ehighways resolution. The mapping from statistical units to ehighways regions is defined in ./ehighways/statistical_units_to_ehighways_regions.csv. ./ehighways/units.png shows a map of the resulting 98 ehighways regions. The region colours are used to help differentiate regions and have no other meaning. This dataset is used as an input to the Sector-Coupled Euro-Calliope workflow.
