As part of its energy storage funding initiative, the German Federal Ministry for Economic Affairs and Energy has granted €6.7m funding for the M5BAT project, which is planned to be commissioned in mid-2016.
The project involves integration of different battery technologies, and is expected to help improve the renewable energies in the country, the company said.
E.ON is currently converting a former office building in the RWTH to accommodate the installation, which spans over two floors and the roof.
Partners in the project include E.ON Energy Research Center, which will be responsible for coordinating the batteries assembly, Exide and SMA Solar Technology will supply the technical components.
Institute of Power Systems and Power Economics at RWTH Aachen University (IAEW) is also participating in the project.
E.ON management board chief markets officer Bernhard Reutersberg said: "The findings expected from M5BAT are of value for the entire energy industry, particularly as a means of support on the path towards low-CO2 power generation."
