Repowering and expansion: Sonnenberg V wind farm becomes a showcase project – ENERTRAG and EBERT conclude cooperation agreement

Dauerthal/Groß Germersleben, 24 July 2025 – The energy transition in Saxony-Anhalt has reached a new milestone: With one of the largest repowering projects in Germany to date, ENERTRAG SE and EBERT Erneuerbare Energien are sending a strong signal for the meaningful and value-creating expansion of wind energy. In July 2025, the cooperation agreement for the joint implementation of the Sonnenberg V wind farm was signed – a project with clear regional roots and a nationwide exemplary effect

ENERTRAG has been active on site as the operator of the existing wind farm with 37 turbines for almost 20 years and maintains good relations with the land owners, the farmers and the municipality of Oschersleben.

EBERT Erneuerbare Energien has been active in the region since 2020 and, together with a group of regional land owners, has set up the "Bürgerwindpark Groß Germersleben Planungsgesellschaft mbH & Co. KG" (BEG), which acts as an operational cooperation partner with ENERTRAG . EBERT controls the planning processes, is responsible for structuring local participation and ensures professional implementation in close coordination with agriculture.

The strategic partnership between Enertrag and Ebert now serves as the basis for the repowering project, in which, more than ever before, the participation of the municipality, farmers and local citizens is in the foreground. The flagship of this partnership is the successful implementation of a joint land pool with over 400 plots of land in order to allow the owners to benefit equally from the project.

The early involvement of the municipality in the planning process ensures that local interests are taken into account.

Part of the energy generated in the Sonnenberg V wind farm in the future will be used to feed the electrolyser currently under construction in Osterweddingen near Magdeburg. This is a component of ENERTRAG's large integrated power plant system for renewable energy generation, storage, use and reconversion. The project thus makes a significant contribution to the development of sector coupling in Saxony-Anhalt.

Regional anchoring through close partnership with owners and farmers

What makes the Sonnenberg V wind farm special is its structured cooperation with the municipality as well as local land owners and farmers from Groß Germersleben, Klein Oschersleben and Peseckendorf. They not only act as space providers, but are also part of a land pool as active project partners, which was planned in a coordinated manner from the outset. Regional value creation thus remains in the hands of the municipalities – a concept with rarity value.

Project scope and planning progress

As part of the project, a total of 29 wind turbines of the latest generation are to be erected – with outputs of between 6 and 8 MW per turbine and a total nominal output of up to 235 megawatts. This makes Sonnenberg V one of the largest individual projects for repowering in Germany. The application for approval under the Federal Immission Control Act (BImSchG) has already been submitted. A uniform plant design with tower heights and turbine types that are as homogeneous as possible is planned in order to exploit synergy effects in operation and maintenance.

Responsibilities and Project Architecture

The project development is based on a clear distribution of roles:

• ENERTRAG and EBERT are jointly developing the site concept of the wind farm as well as the associated grid and access road planning.

• ENERTRAG is responsible for urban land-use planning and the coordination of the approval process. In addition, ENERTRAG assumes the role of applicant for the BImSchG procedure.

• The citizen energy company initiated by EBERT contributes land rights with its local shareholders and actively participates in the project design.

• A joint infrastructure company is planned, in particular to implement the development economically.

The aim is to divide the project rights proportionately after approval: ENERTRAG will receive 73%, BEG 27%. In addition, one of the facilities will be reserved for the participation of a municipal or citizen-owned company – an innovative step to promote local acceptance.

"This project is a real milestone for us," says Dr. Tim Ebert, Managing Partner of the EBERT Renewable Energy Group. "What makes it special is that the land owners are not only participants, but also active co-creators. The close involvement of agriculture and regional actors is our unique selling point and strengthens local value creation."

Tom Lange, Senior Vice President Wind & PV Germany at ENERTRAG, emphasizes:

"The project shows how regional participation, economic perspective and technical implementation can go hand in hand at the highest level. Together with our partners, we are pursuing the goal of bringing climate-friendly energy generation to the regions – in a structure that benefits everyone."

Start of construction and outlook

Construction is scheduled to start in the 2nd half of 2027, subject to official approvals. Depending on the dismantling of the existing 37 old turbines, the construction of the new wind turbines will take place step by step. The eligibility of individual old plants for EEG funding until the end of 2031 will be taken into account – the dismantling will be coordinated accordingly.

With the Sonnenberg V wind farm, ENERTRAG and EBERT are sending a strong signal for the future of wind energy in Saxony-Anhalt – technologically modern, structurally innovative and firmly anchored in the region.

About ENERTRAG

ENERTRAG has been implementing the energy transition for more than 25 years. More than 1,200 employees plan, build and operate integrated power plants: based on wind and solar plants, their own grid infrastructure, batteries and electrolyzers. These provide electricity, heat and green hydrogen reliably and according to demand – and thus replace any fossil fuel power plant.

With our own plants, we generate around 2,000 gigawatt hours of electricity annually from wind and solar and, since 2011, green hydrogen. On this basis, we develop energy projects with a capacity of over 30 gigawatts – in nine countries on four continents.

ENERTRAG stands for the global energy supply of the future: sustainable, secure, regionally anchored. So that our earth remains worth living in.
