RWE AG has contracted SMA Solar Technology AG to supply battery inverters for its 117 MW battery storage system project in Lingen (Lower Saxony) and Werne (North Rhine-Westphalia) in Germany.
The storage project will provide a range of important system services needed for maintaining grid stability to support fluctuations in the availability of renewable energy. SMA Solar Technology will supply a system technology used for integrating and optimally controlling the charging and discharging of the 420 lithium-ion battery racks of the battery storage system.
Once completed at the end of 2022, the project will be one of the most innovative in Germany, because the battery storage systems will be virtually coupled with RWE’s run-of-river power plants along the river Mosel. By raising or decreasing the flow-through at these power stations, RWE can make additional capacity available as well as balance energy. It can raise the total capacity of the batteries by another 15%.
