The significance of hydropower storage for the energy transition

Prognos AG was commissioned by the World Energy Council Germany to compile a study on the significance of international hydropower storage for the energy transition in Germany.
A year after the launch of the energy transition, implementation issues have been discussed intensively. In this context, it needed to be clarified to what extent hydropower storage installations abroad can contribute to absorb excess electricity from renewable energy sources and to make back-up electricity available. In this context, the present expert report attempts to give a realistic assessment of the contribution of international hydroelectric storage capacities to the energy transition in Germany. In addition to Germany, countries such as Norway, Sweden, Switzerland and Austria formed part of the survey, because they have large hydroelectric storage facilities. It will be discussed, inter alia, how these potentials can be utilised in an effective and economically viable manner.
