BayWa r.e. and Rheinland Solar Launch 10 MWh BESS for Solar Optimization in Germany
BayWa r.e. and Rheinland Solar have implemented a 10 MWh battery energy storage system at a logistics facility in Mutterstadt, Germany, to enhance solar power utilization. The system improves energy flexibility and self-consumption for the existing 3 MWp solar plant, addressing previous curtailment issues.

A 10 MWh battery energy storage system (BESS) has been deployed by BayWa r.e. Solar Energy Systems GmbH, SOCOMEC, and Rheinland Solar GmbH at a logistics site in Mutterstadt, Germany. This project started in October 2025, with the delivery of two SOCOMEC SMARTSYS M5000 systems completed by June 2026.
Each unit offers 2.5 MW output and 5 MWh storage capacity, enabling the site’s existing 3 MWp photovoltaic system to utilize excess solar power effectively. The new system will enhance on-site self-consumption, reduce peak loads, and improve supply reliability. This installation marks SOCOMEC's 500th energy storage system globally, underscoring its collaboration in commercial energy storage.
