3 min read

With a storage capacity of 25 megawatt-hours, the facility makes an important contribution to the regional energy transition and the stability of the local energy supply. At the open day, visitors had the opportunity to experience the large-scale battery storage system firsthand and learn more about its importance for the region.


Lauben/Kempten, August 10, 2026


green flexibility has officially opened its new large-scale battery storage system in Lauben, in the Unterallgäu district. With the opening, the company is making another important contribution to the energy transition in the region and demonstrating how modern battery storage technologies can support the integration of renewable energy and enhance power grid stability.

The Lauben battery storage system has a power output of 10 megawatts and a storage capacity of 25 megawatt-hours. The facility is another battery storage project by green flexibility within the grid area of LEW Verteilnetz GmbH, strengthening the regional energy infrastructure in the Allgäu region. green flexibility invested around €10 million in the development and construction of the project.


Experience Battery Storage – Open Day in Lauben


As part of the official opening of the large-scale battery storage system in Lauben, green flexibility opened the facility to the public for an open day.

Numerous local residents, project partners, and representatives from politics, business, and the energy sector accepted the invitation to the opening event and took the opportunity to experience the new battery storage system up close. In direct discussions with green flexibility’s experts, visitors gained insights into the technical infrastructure and the role of battery storage in ensuring a secure and sustainable energy supply.


The municipality and local associations played a key role in the success of the event. The TC Lauben tennis club provided catering, while the volunteer fire brigade supported traffic and parking management. This shared commitment highlights the importance of involving local stakeholders in the successful implementation and public acceptance of battery storage projects as part of a future-ready energy infrastructure.


Mayor Mr. Rößle expressed his appreciation for the strong turnout and the close cooperation among all parties involved:

“The large-scale battery storage system is an important project for our municipality and the region. The strong interest shown at the open day demonstrates how important the energy transition and innovative local solutions are to people.”

Deputy District Administrator Christa Bail also emphasized the importance of the project for the region:

“Large-scale battery storage systems such as the facility in Lauben are an important building block for a secure and future-ready energy supply in the Unterallgäu region. They create the conditions needed to use renewable energy efficiently while also strengthening regional infrastructure.”

Christoph Lienert, Co-Founder and COO of green flexibility, emphasized:

“The energy transition can only succeed through collaboration. The large-scale battery storage system in Lauben demonstrates what is possible when the municipality, grid operator, partners, and we as the operator take joint responsibility. The close cooperation with the municipality of Lauben was an important factor in the successful implementation of the project and shows how regional energy transition projects can be developed through strong local partnerships.”

Grid-Neutral Integration for Greater Flexibility in the Regional Energy System


A particular focus of the project is its integration into the local grid. Through the REGIOlink concept developed by green flexibility, a Flexible Connection Agreement (FCA) was implemented in close cooperation with the grid operator. The agreement takes into account both the requirements of the regional grid and the conditions necessary for the economically sustainable operation of the battery storage system.


With its grid-neutral operating strategy, green flexibility takes an approach that goes beyond purely market-driven battery storage operation, specifically aligning the operation of large-scale battery storage with the requirements of the regional grid infrastructure.


The Lauben project underlines green flexibility’s commitment to developing solutions together with municipalities, grid operators, and partners that make a sustainable contribution to a secure and future-ready energy supply.
