  Efforts to reduce climate change, but also falling prices and significant
technology developments currently drive an increased weather-dependent
electricity production from renewable electricity sources. In light of the
changing climate, it is highly relevant to investigate the extent of weather
changes that directly impacts the best system design decisions for these
weather-dependent technologies. Here, we use three IPCC representative CO2
concentrations pathways for the period 2006--2100 with six high-resolution
climate experiments for the European domain. Climate elements are used to
calculate bias adjusted 3-hourly time series of wind and solar generation, and
temperature corrected demand time series for 30 European countries using
state-of-the-art methodology. Weather-driven electricity system analysis
methodology is then applied to compare four key metrics of highly renewable
electricity systems. We find that climate change does not have a discernible
impact on the key metrics of the combined electricity system dynamics, and
conclude that the effect on important system design parameters can likely be
ignored.
