Electricity by Intermittent Sources — •Friedrich Wagner — Max-Planck-Institut für Plasmaphysik, Greifswald, Germany

We describe the major characteristics of an electricity supply system being predominantly composed of the scalable renewable energy (RE) forms wind and photovoltaic power. The analysis is mostly based on the actual production data of 2013 from the German electricity system. The 2013 data will be scaled to larger shares of RES in the electricity production up to the 100% case where RES integrally generate as much electricity as consumed during a year. The 100% case is then analysed according to the proper mix of wind and PV power, the extent of installed power, the remaining residual back-up power, the dynamics of the back-up system, the size of storage, the conditions for demand-side-management, the CO2-reduction in comparison to other supply forms and finally with regard to some cost issues. Similar analyses are carried out for some European countries using only their national RE-power field. A rough picture emerges on the viability of using RES in Europe. Finally, an EU-wide RE power field is constructed from the superposition of the national contributions. This allows to assess the reduction of the degree of intermittency and the necessary interconnection capacity to benefit from this effect.
