The Alfeld project is set to become Germany’s largest battery energy storage system (BESS), featuring 137 MW of output and 282 MWh of capacity. The system is currently under construction with commercial operation scheduled to start at the beginning of Q3 this year. It will be used primarily to provide ancillary services, in particular primary control reserve, and make a significant contribution to grid stability and security of supply in the future.
This contract represents one of the first external standalone battery assets for BayWa r.e., which had previously operated only its own storage systems within hybrid (solar & wind co‑location) projects.
“This deal marks a significant milestone for BayWa r.e. in the operational management of battery storage systems in Germany and beyond” said Dr. Daniel Gäfke, COO of BayWa r.e., welcoming the agreement.
Battery Energy Storage Systems represent the backbone of the renewable energy infrastructure. As wind and solar power continue to expand at scale, the demand for flexibility, grid stability, and reliable availability is rising sharply. In this evolving landscape, BESS play a pivotal role and stand among the most promising drivers of innovation in the renewables industry, while economic success depends heavily on efficient operations.
“BESS are a science of their own and still a relatively young technology” added Simon Slapka, Managing Director of Data Services GmbH. “Our approach combines deep technological expertise and advanced digital asset management methods, supported by close collaboration with leading software specialists, like TWAICE. We are proud of this achievement, having secured the contract in a comprehensive tender process against strong competition.”
