PV plant supplies around 2,350 households with solar power; battery storage system improves grid flexibility and enables time-shifted renewable energy supply
Since mid-September 2025 the new solar park operated by EnBW Energie Baden-Württemberg AG in Wangen im Allgäu has been feeding electricity into the grid. After five months of construction, the 5.7 MWp photovoltaic plant has now been officially commissioned.
The installation will supply the equivalent of around 2,350 households annually (based on a typical consumption of 2,900 kWh per household) and is expected to save more than 4,700 tonnes of CO₂ per year.
Solar park combines generation and storage
The project consists of around 9,600 solar modules and three transformer stations. It is supported by a 6.8 MWh battery storage system, which increases the flexibility of the generated electricity and improves integration into the local grid.
The storage system enables surplus solar power to be stored during periods of high generation and released when demand is higher or when solar production is low, such as during the evening or cloudy periods.
Strategic location supports faster deployment
The solar park is located alongside the A96 motorway, where land within the 200-metre corridor can be used for renewable energy under accelerated permitting rules. This approach is designed to streamline infrastructure deployment along existing transport corridors and reduce land-use conflicts.
Strong local collaboration
The project was developed in close cooperation with the city of Wangen im Allgäu and the local energy cooperative BürgerEnergiegenossenschaft Region Wangen im Allgäu eG.
Wolfgang Friedrich, board member of the cooperative, said the project demonstrates how local communities can actively participate in the energy transition while benefiting directly from it.
The grid connection was simplified by using existing infrastructure. The connection point is located directly on site, avoiding the need for additional cable routes. A transmission line crossing the area had already been rerouted underground by grid operator Netze BW prior to construction.
Battery storage strengthens grid stability
The 6.8 MWh battery system was added in early 2026 and installed near the substation on the eastern part of the site.
Project manager Thomas Uhland from EnBW explained that the system stores excess solar energy and releases it when needed, helping to stabilise the grid and improve the reliability of renewable electricity supply.
Battery storage is increasingly seen as a key technology for enabling high shares of renewables in the power system.
Economic benefits for the local community
The city of Wangen benefits directly from the project through increased tax revenues and a voluntary contribution from EnBW under Germany’s renewable energy framework.
These funds can be allocated to local priorities such as education, childcare facilities, or community projects.
Mayor Michael Lang described the project as a practical example of how the energy transition can deliver tangible local benefits alongside climate impact.
About EnBW
EnBW Energie Baden-Württemberg AG is one of the largest energy companies in Germany and Europe, with around 31,500 employees and approximately 5.5 million customers.
The company operates across generation, trading, grid infrastructure, and energy supply. Its strategy is focused on transforming into a sustainable infrastructure provider with major investments in renewable energy and network expansion.
By 2030, EnBW plans to invest up to €50 billion, with around 85% allocated to Germany. By then, around 80% of its generation portfolio is expected to come from renewable energy sources, supporting its net-zero target for operational emissions by 2040.
