green flexibility realizes 25 MWh storage project in Lauben - grid-neutral integration for greater stability in Southern Bavaria

With the construction of a 25 MWh large-scale battery storage system in Lauben, green flexibility is investing around 10 million euros to strengthen the regional energy infrastructure. In order to account for constraints in the local power grid, a grid-neutral mode of operation was agreed upon with the grid operator.


Kempten, 04.08.2025


Energy storage systems are a key component of the energy transition—especially where they can be meaningfully integrated at the regional level. They make it possible to better align electricity supply and demand and provide urgently needed flexibility in an increasingly volatile energy system. With projects like the one in Lauben, green flexibility is actively advancing this development.


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 Lauben, in the Unterallgäu region. 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.

A Step Toward Energy Security and the Energy Transition


The storage system will help relieve the power grid, buffer peak loads, and temporarily store surplus energy from wind and solar plants. With the ability to absorb or release electricity within seconds, the facility makes a significant contribution to regional energy security 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 Lauben — sending a clear signal for regional value creation and cooperative project development.
