BayWa r.e., Ampt and Fraunhofer complete ‘European-first’ wind-solar-flow battery hybrid project in Germany

February 27, 2024

A microgrid project combining solar PV, wind and a 10MWh flow battery in Germany has been completed by BayWa r.e., Ampt and Fraunhofer.

The completion of the project was announced today (27 February) by renewable energy developer and independent power producer (IPP) Baywa, power conversion technology provider Ampt and research institute Fraunhofer. The project is located at the Fraunhofer Institute for Chemical Technology (ICT) campus in Pfinztal, southwest Germany.

A 690kWp solar PV array has been added to an existing 2MW wind turbine, which have been ‘DC-coupled’ meaning both sit behind the same inverter using Ampt’s string optimisers. The companies claimed this combination of solar PV, wind and storage is unique in Europe, and that the project would help Fraunhofer ICT’s campus towards climate-neutrality.
