At the present the energy mix in European countries is still dominated by traditional sources. Nuclear, coal and gas play a major role at several European countries. As this energy mix is under transition especially dominated by Germany future demands on grid stability due to volatile energy production will occur. Energy predictions up to 2050 show a big share on wind and solar installed. Generally we know that these installations can only be done by having some back-up system in terms of storage capacities.

Checking different studies it seems that pumped storage alone is not enough to fulfill the requirements. Therefore all storage possibilities and their capacity should be discussed from different point of view. A key role plays the dispatch center to guarantee our daily electricity. They have also to guarantee the frequency and load control therefore it is mandatory to speak about the contribution of each single renewable energy source technology to these overall objectives.

A major key role beside all these discussions plays the development of the electrical grid in each member country and of course on a European wide level (UCTE). Many projections for the future energy mix are naturally based on the development of the electrical grid. But as we all know, construction of the electrical grid has the same troubles and administrative process like we know from the installation of new hydropower plants. If we impose that the development of the electrical grid will not be as fast as assumed we have to ask about alternatives. What can be done, what is possible at the electrical grid to raise the share of renewable energy sources. Is there any limit?

This panel discussion will focus on questions about grid stability and integrity at the UCTE network. Panelists will discuss the future energy mix and their effects to the grid. How can we stabilize a network by increasing the share of renewable energy sources. Also the main findings of the previous panel discussion about trends and innovation needs of Hydropower Plants should be included.
