green flexibility brings 25 MWh storage project to Krumbach – grid-neutral integration for greater stability

In Krumbach, green flexibility is constructing a 25 MWh large-scale storage system, investing around €10 million in the regional energy infrastructure. To take local grid bottlenecks into account, a grid-neutral operating mode was agreed with the grid operator to ensure stable and sustainable integration into the power grid.


Kempten, 27. August 2025


Energy storage systems are indispensable for the success of the energy transition - especially when they are sensibly integrated into regional structures. They create urgently needed flexibility in an increasingly volatile energy system and help to better balance electricity supply and demand. With projects such as the one in Krumbach, green flexibility is actively driving this development forward.


Located in close proximity to an existing substation, a large-scale battery storage facility with a capacity of 10 MW and 25 MWh is being built in Krumbach. The site was deliberately chosen to make efficient use of the existing grid infrastructure. At the same time, the connection—planned in coordination with the grid operator - enables grid-neutral operation, ensuring that the local power grid is not further burdened during times of regional congestion. This approach is based on green flexibility’s REGIOlink concept. As a result, the storage system can be operated flexibly and economically—while remaining fully grid-neutral.


“REGIOlink has become an integral part of many of our projects - and in Lauben, we’re using selected components of it to ensure grid-neutral operation. This creates real added value for the region without putting additional strain on the grid - and at the same time, we’re accelerating the transition to a more decentralized and stable energy system,” explains Christoph Lienert, Co-Founder and COO of green flexibility.

Battery storage strengthens security of supply in Krumbach


The battery storage in Krumbach will help stabilize the power grid, absorb peak loads, and temporarily store excess energy from wind and solar power plants. With its ability to absorb or release electricity within a very short time, the facility makes an important contribution to security of supply in the region—and to the flexibility of an increasingly decentralized energy system.


As with all its projects, green flexibility places great importance on collaboration with local stakeholders in Krumbach - sending a clear signal for regional value creation and cooperative project development.
