Spatio-temporal generation patterns for wind and solar photovoltaic power in Europe are used to investigate the effect of an increasing penetration of these variable renewable energy sources (VRES) on the European electricity system, in particular on the required link capacities of the transmission grid. VRES growth predictions according to the official National Renewable Energy Action Plans of the EU countries are used and extrapolated logistically up to a fully VRES-supplied power system. It is examined how the need for transmission rises in the future. We find that quadrupling today's international net transfer capacities over the next forty years reduces the final need for backup energy by more than one third. The remaining backup energy is due to correlations in the generation patterns, and can thus not be reduced by transmission. Additionally, our results show how the optimal mix between wind and solar energy shifts from about 70% to 80% wind share as the transmission grid is enhanced. Finally, we exemplify how reinforced transmission affects the import and export opportunities of single countries during the VRES ramp-up and the coupled transmission grid extension.
