Supergrid and Storage Boost Solar and Wind

Both power sources fluctuate with the weather, so we will inevitably have to think carefully about the infrastructure of Europe’s future power supply system. A Supergrid (on and offshore) will have to be in place besides new flexible units and storage facilities to balance fluctuations and to transfer wind and solar energy from places where they are abundant. Furthermore, to alleviate the inherent seasonal characteristics of wind and solar power generation in Europe and to secure the power supply, large-scale storage will be needed. A study that has been funded by Siemens AG shows that an optimal mix of solar and wind power generation exists which determines a minimum investment into storage and transmission capacities.
