Set to occupy 1.5 hectares, the site will provide 60 MW of output and 240 MWh of storage – enough to supply a medium-sized city with electricity for 12 hours. Construction is scheduled to begin in 2026, with commissioning planned for 2027.
The site is strategically located in a “relief area” designated by E.dis – a region particularly susceptible to grid bottlenecks due to its high proportion of renewable energy generation. The project aims to absorb more locally generated energy and 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.
State-of-the-art technology
The construction of the park will 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. Trade taxes and voluntary participation models in cooperation with the municipality will ensure much of the added value remains local, directly benefiting the region.

The plant also sets new standards in technology. Two dedicated substations with direct connection to E.dis’s 110 kV level ensure grid integration. The modular design allows future expansion. Fast frequency response enables the storage facility to compensate for grid fluctuations in near real time – a significant improvement over conventional gas turbines, which take minutes to respond. The facility can also provide key system services such as primary control power (FCR), secondary and minute reserve (aFRR/mFRR), and black start capability.

Ingo Ernst, CTO & Co-Founder of Re.venture: “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.”

Its modular architecture allows capacity to be flexibly expanded to up to 480 MWh to meet future energy requirements. Construction is scheduled to begin in 2026, with commissioning planned for 2027. (hcn)
