German energy developer Re.venture has announced plans to build a 60-megawatt (MW) battery energy storage system (BESS) in the state of Brandenburg, aiming to support regional grid stability and store surplus renewable electricity.
The planned facility will offer 240 megawatt-hours (MWh) of storage capacity—enough to power a medium-sized city for up to 12 hours. Construction is scheduled to begin in 2026, with commissioning expected in 2027.
Located within a designated “relief area” identified by regional grid operator e.dis, the project is intended to absorb excess renewable energy generation and reduce local grid congestion.
“The new battery plant enables the storage and then the release of green and locally generated energy,” said Re.venture Chief Executive Jens Kompauer. “Every kilowatt hour that we do not have to curtail conserves resources, strengthens industry, and relieves consumers.”
The company said the project will help reduce redispatch and curtailment costs, while contributing to municipal revenues through tax payments and community benefit schemes.
The site will feature two dedicated substations and connect directly to the 110-kilovolt (kV) network. A modular system design will allow potential future expansion to 480MWh.
“Thanks to response times in the millisecond range, the system compensates for fluctuations almost immediately – and can even support the grid restart in an emergency,” said Chief Technology Officer Ingo Ernst.
In addition to energy storage, the plant will be capable of delivering system services such as frequency control and reserve power, in line with Germany’s broader efforts to enhance energy security and integrate higher shares of variable renewables.
