Wind Farm Sonnenberg V: Enertrag and Ebert Launch one of Germany’s Largest Repowering Projects

Dauerthal/Groß Germersleben (Germany) – With the Sonnenberg V wind farm, renewable energy service providers Enertrag and Ebert aim to set a nationwide example for modern wind energy. The project stands for regional participation, innovative sector coupling, and a cooperative partnership between business, agriculture, and municipalities.

A joint land pool, citizen participation, and a direct contribution to hydrogen production: the Sonnenberg V repowering project aims to combine technological innovation with regional value creation — underpinned by a collaborative project structure between Enertrag and Ebert. With Sonnenberg V, the two companies intend to demonstrate how modern wind power projects can be implemented efficiently, with public involvement, and future-proofed — creating a regionally anchored project that serves as a national model.

Joint Effort with Model Character

Even before construction begins, the new Sonnenberg V wind farm in Groß Germersleben, Saxony-Anhalt, is considered a flagship project for Germany’s energy transition. With the goal of installing up to 29 modern wind turbines with a total capacity of up to 235 MW, the project is among the largest repowering initiatives currently underway in the country. In July 2025, Enertrag and Ebert Erneuerbare Energien sealed their strategic partnership — with clearly defined roles and strong regional roots.

What makes this project particularly noteworthy is the deep involvement of local stakeholders: over 400 plots have been organized into a shared land pool, enabling farmers and landowners from Groß Germersleben, Klein Oschersleben, and Peseckendorf to directly share in the project's economic success. “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,” says Dr. Tim Ebert, Managing Partner of the EBERT Renewable Energy Group.

Sonnenberg V is also pioneering in terms of energy utilization: part of the energy generated will be used to power an electrolyzer currently under construction in Osterweddingen near Magdeburg — an important component of Enertrag’s hybrid power plant strategy. The facility will produce green hydrogen and support the cross-sector energy transition in Saxony-Anhalt.

Structured Planning Meets Regional Value Creation

The Sonnenberg V wind farm will replace 37 older turbines with more powerful models, each delivering between 6 and 8 MW. A standardized turbine design is planned, with consistent tower heights and types to maximize synergies in operations and maintenance. The permit application under the Federal Immission Control Act has been submitted, and construction is scheduled to begin in the second half of 2027, pending all necessary approvals.

The project structure relies on clear responsibilities: both companies will jointly develop the site layout and the associated grid and access infrastructure. Enertrag is in charge of land-use planning and coordinating the approval process. Ebert contributes local land rights through its citizen energy cooperative and is actively involved in shaping the project. A joint infrastructure company is also planned.

“The project shows how regional participation, economic prospects and technical implementation can go hand in hand at the highest level,” says Tom Lange, Senior Vice President Wind & PV Germany at Enertrag.

The goal is to divide the project rights after approval: Enertrag will receive 73%, and the citizen energy cooperative (BEG) 27%. In addition, one of the turbines will be reserved for participation by a municipal or citizen-led entity — a move intended to boost local acceptance.
