German renewable energy firms Enertrag and Ebert Erneuerbare Energien have signed a cooperation agreement to jointly develop the Sonnenberg V wind farm, one of the country’s largest wind repowering projects, located in Saxony-Anhalt.
The plan involves replacing the existing 37 older-generation turbines with 29 modern wind turbines, delivering a total installed capacity of up to 235 megawatts (MW). Enertrag has operated the original wind farm for nearly two decades and maintains longstanding ties with local landowners, farmers, and the municipality of Oschersleben.
“This project is a real milestone for us,” said Tim Ebert, managing partner at Ebert. “What makes it special is that the landowners are not just stakeholders, but active participants. The close involvement of the agricultural community and regional stakeholders is our unique selling point and strengthens local value creation.”
As part of the partnership, Ebert has established a citizen energy company (BEG) together with regional landowners. BEG will serve as a key partner in the project and contribute land rights through its shareholders. A joint land pool covering more than 400 individual plots has been set up to ensure landowners benefit directly from the development.
An application for approval under the Federal Immission Control Act has already been submitted. Construction is expected to begin in the second half of 2027, subject to regulatory approvals, with turbine installation to proceed in phases alongside the dismantling of the existing units.
Tom Lange, senior vice president for wind and solar at Enertrag in Germany, said: “The project shows how regional participation, economic prospects 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 production to the regions – in a structure that benefits everyone.”
A portion of the electricity generated by the repowered Sonnenberg V wind farm will supply a green hydrogen electrolyser currently under construction in Osterweddingen, near Magdeburg.
