en.Wedoany.com Reported - Germany's energy storage market has recently seen several significant developments: Aquila Clean Energy EMEA has secured financing for a standalone battery energy storage project, Chint Solar has sold a portfolio of projects to Second Foundation, and Twaice is providing battery analytics services to BayWa r.e. These announcements come as the European Battery Show and Energy Storage Summit takes place in Stuttgart, Germany (June 9–11).

Independent power producer Aquila Clean Energy EMEA has reached financial close for its Wetzen project (56MW/112MWh standalone battery energy storage system) in Lower Saxony, Germany. The financing was provided by INC Deutschland, with a debt volume exceeding €26 million ($30 million). Aquila stated that this is one of the first fully commercial BESS financings of its kind in the German market, where other projects typically require a certain degree of contracted, guaranteed revenue to secure external project financing, or rely solely on corporate balance sheets. Optimizer Entrix will trade the BESS in the market along with another project of similar scale, which are the first two in a portfolio of 14 projects Aquila plans to deploy in Germany. Grace Kankindi, Deputy Head of Investment Management at Aquila, previously noted that German lenders are increasingly willing to support large-scale BESS projects in the country that lack any contracted revenue.
Developer and EPC company Chint Solar Europe has sold five BESS projects in Germany (totaling 56MW/180MWh) to Czech energy trading firm Second Foundation. As part of the transaction, Chint Solar will also build and maintain these projects under EPC and O&M contracts. The projects are located in Saxony, Saxony-Anhalt, and Brandenburg, and will be commissioned between Q2 2026 and Q3 2027. Second Foundation, primarily an energy trading company and one of the largest in Germany, is now shifting toward owning and operating BESS projects. The company will commission 307MW in the Czech Republic this year and secured a BESS optimization deal with Finland's Winda Energy last year.
Battery analytics company Twaice will service a 137.5MW/282MWh BESS (the Alfeld project), for which developer and renewable energy services company BayWa r.e. recently announced the signing of an O&M contract. BayWa is providing full O&M services for project owner Scale Fund, which purchased the project from developer Kyon Energy. Twaice will offer a vendor-independent view of BESS performance, helping to identify underperformance issues earlier, prioritize correct actions, and bring transparency to daily operations. The Alfeld project is scheduled to be commissioned in Q3 of this year and will become the largest project of its kind in the country.
