German pumped storage technology

How would Germany benefit from pumped storage systems?

The secured capacity from pumped storage systems can rise to up to 16GW. Germany would be able to build and run fewer new gas power plants. The operation of the pumped storage systems would be profitable, and power generation costs would drop. At the same time macro-economic benefits are expected.

What is Germany's largest pumped storage project?

The Goldisthal pumped storage project, at 1060MW is Germany’s largest, followed by Markersbach at 1050MW. Both projects are owned by Vattenfall, which plans to raise the height and regenerate the upper and lower reservoirs of the Markersbach plant in 2015-16.

How much electricity can pumped storage systems use in Germany?

The study shows that with a 60% share, about 2TWh of electricity can be additionally utilized, if the pump storage systems in Germany are extended to a capacity of 15GW. At the same time, up to 13GW of secured capacity from pumped storage systems would be available.

Will pumped-hydro storage regain momentum in Germany?

The development of pumped-hydro storage in Germany regains momentum. ► The installed capacity could increase by more than 60% within 10 years. ► The regulatory framework changed, barriers for storage plants have been removed. ► However, profitability remains a major hurdle for new build projects. 1. Introduction

Could pumped storage reduce the need for new gas power plants?

A recent study shows that pumped storage could reduce the need for new gas power plants in Germany and help with the integration of renewable energies from 2030.

Why do we need pumped storage power plants?

“Pumped storage power plants are multi-function power plants, which help us to lead our energy system swiftly and smoothly into the new era of energy generation without fossil carriers," says Heike Bergmann, Board Member of Voith Hydro in Germany. “It is obvious that we need more storage capacities for the energy transition.
