Prospects for pumped-hydro storage in Germany

Abstract

After a period of hibernation, the development of pumpedâ€hydro storage plants in Germany regains momentum. Motivated by an ever increasing share of intermittent renewable generation, a variety of energy players considers new projects, which could increase the available capacity by up to 60% until the end of the decade. This paper analyzes the current development and evaluates the revenue potential as well as possible barriers. Overall, the prospects for new pumpedâ€hydro storage plants have improved, even though profitability remains a major challenge.pumped-hydro energy storage, power plant investment, Germany
