green flexibility and VWEW-energie launch a joint 10 MW energy storage project in Marktoberdorf.

Kaufbeuren / Kempten, November 25, 2025


green flexibility and Vereinigte Wertach-Elektrizitätswerke GmbH (VWEW-Energie), headquartered in Kaufbeuren, are jointly implementing a forward-looking energy project: a large-scale battery storage facility with a capacity of 10 megawatts is being developed in Marktoberdorf.


With the growing feed-in of electricity from photovoltaic and wind power systems into the grid, the demand for flexible storage solutions is increasing - solutions that can absorb surplus electricity on a large scale and release it again when needed. The battery storage facility in Marktoberdorf, which will be jointly operated by green flexibility and VWEW-Energie, fulfills precisely this function by reducing peak loads and strengthening the stability of the regional power grid. By strategically storing and feeding renewable electricity back into the grid, the facility makes a significant contribution to grid flexibility and security of supply.


With an output of 10 MW and a storage capacity of 25 MWh, the facility will be operated in a grid-neutral manner and will utilize components of green flexibility’s REGIOlink concept - an approach that takes the regional grid situation into account and enables intelligent, grid-neutral operation. The joint investment amounts to approximately EUR 10 million, with commissioning scheduled for the end of 2026.


With the new battery storage facility, a significant contribution is being made in the Ostallgäu region to strengthening regional security of supply and to the integration of renewable energies. The project underscores VWEW-energie’s commitment to actively shaping both the energy transition and the regional energy supply, deploying innovative technologies and thereby ensuring that the power grids remain future-ready and stable.


“The expansion of renewable energies, which we have been successfully advancing for many years, is a central pillar of the energy transition. The key challenge now is to store electricity from wind and solar power so that it can be used as flexibly as possible when it is needed,” says VWEW Managing Director Stefan Fritz, commenting on the project and the partnership.

Collaboration for the Energy Transition

The cooperation between a regional energy utility and a specialized developer and operator of battery storage systems is still regarded as exceptional within the industry - and as a potential blueprint for the energy transition through the collaboration of municipal utilities, grid operators, and innovative technology providers.


“We are consistently pursuing a collaborative approach to developing and implementing projects together. Only by bringing together the perspectives of all stakeholders can a successful and stable energy transition be achieved. Our cooperation with VWEW-energie is an excellent example of this,” says Christoph Lienert, Co-Founder and Managing Director of green flexibility.


Über green flexibility

As a leading expert in the energy transition, Green Flexibility combines in-depth expertise with cutting-edge battery storage technology to make the energy infrastructure of the future reliable, flexible, and sustainable. As an end-to-end partner for battery storage systems, Green Flexibility plans, constructs, and operates storage facilities at strategically important points within the power grid. In doing so, Green Flexibility manages all project phases—from identifying suitable sites to the operation and commercialization of the storage systems.


Über VWEW-energie

VWEW-Energie is a 100% municipally owned energy company, deeply rooted in the Allgäu region, supplying electricity and natural gas to private, commercial, and industrial customers both locally and across Germany. With seven hydropower plants and photovoltaic installations, VWEW-Energie produces environmentally friendly green electricity - enough to supply approximately 12,000 households. The company operates an electricity network of around 2,000 km to support this. In addition, VWEW-energie offers its customers comprehensive services in the areas of photovoltaics, battery storage, heat pumps, and e-mobility, complemented by energy consulting and energy audits. Furthermore, VWEW-energie actively supports and promotes social and sustainable projects in the region. https://vwew-energie.de/strom-gas
