In 2017, Susanne Kleineheismann started to work for the corporate group Max Bögl. She is responsible for the development and implementation of international sales structures for the Water Battery within the Max Bögl Wind AG.
Previously she worked in a renowned technical design office for offshore foundations of wind turbine generators and as a construction manager for special foundation works in Germany and Hong Kong.
Susanne Kleineheismann studied successfully civil engineering at the Nuremberg Institute of Technology in Germany and holds a Master degree in International Civil Engineering with ECTS-grade A+. The Technical University Carolo-Wilhelmina at Brunswick in Germany honored her outstanding achievements in 2015.
The water battery is an innovative storage medium for renewable energies, which can absorb surplus electricity from the grid and discharge it on demand. As a high-performance short-term storage solution, the water battery is ideal for balancing fluctuations in power networks. When required, the pumped storage power plant provides electricity within 30 seconds and feeds the stored energy back into the grid. The water battery enables us to participate in all electricity markets in a flexible and quick way.
A new combined power plant system that is innovative both in terms of its construction and usage is currently being developed at our pilot project site in Gaildorf. The four wind turbines are being complemented by a pumped storage power plant. The system uses the tower bases of the wind turbines to store water. Specially developed penstocks connect the upper reservoirs with a hydroelectric power plant and a lower reservoir down in the valley.
The combination of wind and water power reduces the demand for conventional pumped storage power plants, which often require extensive alterations to the landscape and elaborate planning procedures. In addition, the system reveals attractive marketing opportunities in the electricity sector (day-ahead and intraday trading, frequency regulation, peak shaving, etc.). The use of reversible Francis turbines in the power house allows for greater trading flexibility on the energy market, higher revenues and the possibility to forecast the otherwise extremely volatile yield from renewable energies. The Federal Ministry for Environment, Nature Conservation, Building and Nuclear Safety is supporting the project with a 7.15 million euro fund.
