German university to build modular large-scale battery storage system

Project developers started construction of the modular large-scale battery storage system M5BAT on the premises of RWTH Aachen University in Germany.

Energy storage systems like this represent an important building block for the expansion of renewable energy, as they make a contribution to system stability, developers said.

M5BAT is backed by a $7.5 million grant from the German Federal Ministry for Economic Affairs and Energy as part of its “Energy Storage Funding Initiative”. The project’s partners include the E.On Energy Research Center and the Institute of Power Systems and Power Economics at RWTH Aachen University (IAEW), the energy company E.On, the battery manufacturer Exide Technologies GmbH with its business unit GNB Industrial Power, and the inverter manufacturer SMA Solar Technology AG.

The storage system will be located in a former office building that is being converted specially for the installation. In total, the batteries and all other components of the power storage system will stretch over two floors and the roof, covering total floor space of about 500 square meters.

The building conversion is being carried out by E.On, while the E.On Energy Research Center will take charge of coordinating the assembly of the batteries. The manufacturers Exide Technologies and SMA Solar Technology AG are supplying the technical components. The battery storage system is due to be completed in mid-2016.
