Berlin-based project energy and storage solutions developer re.venture is to develop and build a large-scale battery storage park in Brandenburg, Germany. The project will be one of the largest such plants in the country. It will cover an area of 1.5 hectares, have an output capacity of 60 MW and a storage capacity of 240 MWh – enough to supply a medium size city with electricity for 12 hours. Construction is set to begin in 2026, with commissioning planned for 2027.
The site is strategically located in a so called “relief area” as designated by regional distribution system operator e.dis. That is, a region that is particularly susceptible to grid bottlenecks due to its high proportion of renewable energy generation. The aim of the project is to absorb more locally generated energy and, at the same time, increase grid stability through greater flexibility.
“Significant amounts of renewable electricity have to be curtailed every year in Germany, because the grid cannot absorb the energy generated. The new battery plant enables the storage and then the release of green and locally generated energy. Every kilowatt hour that we do not have to curtail conserves resources, strengthens industry, and relieves consumers,” said Jens Kompauer, founder and CEO of re.venture GmbH.
The construction of the park is anticipated to bring significant economic benefits – the need for costly redispatch and curtailment measures will decrease, system costs will be reduced, and the region’s attractiveness as a location will increase.
The plant is expected to set new standards in terms of technology: two dedicated substations with a direct connection to the e.dis 110 kV level ensure direct integration into the grid. The modular design allows for future expansion as needed. Thanks to fast frequency response, the storage facility compensates for grid fluctuations in near real time – a significant improvement over conventional gas turbine solutions, which take several minutes to respond. In addition, the storage facility can provide important system services such as primary control power (FCR), secondary and minute reserve (aFRR/mFRR), and black start capability.
“With the new plant we are relying on state-of-the-art storage technology. 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 Ingo Ernst, CTO and co-founder of re.venture GmbH.
