Clustering Dataset

<pre>This dataset contains jointly optimised energy system model networks on transmission and generation level with the objective to minimise total system costs under the constraint to reduce 95% of CO2 emissions compared to 1990 by a greenfield approach. We vary the spatial resolution on different scales (clustering on generation sites, the transmission network and joint clustering) to research the impact of each scale separately for the optimisation process. For each resolution, we additionally consider seven different transmission line expansion volumes. Results indicate, that in the current European transmission system, transmission network bottlenecks play a more restricting role than resource availability. Accounting for bottlenecks can raise total system costs by up to 19%, while a higher resource availability (locations with higher capacity factors) mitigates the increase only by 6.5%. Both cases result in strong differences in the composition of technology investments. A detailed survey of the results will be presented in the paper "The strong effect of network resolution on electricity system models with high shares of wind and solar".</pre>
