Greening has secured an Engineering, Procurement, and Construction (EPC) contract to develop a solar park at the site of the former Wilhelmshaven thermal power plant, located in Lower Saxony. The project, which will have an installed capacity of 17MWp, is set to be built on the ash dump of the decommissioned plant, which is owned by Uniper.
Covering approximately 14 hectares, the solar park will be equipped with more than 28,500 solar modules. These modules will be anchored using specialized systems designed to ensure stability on the landfill site. The project is expected to generate approximately 17,000MWh annually, enough to supply around 4,500 homes with 100% renewable electricity.
The scope of the project includes constructing two medium voltage line circuits, totaling roughly 5 kilometers in length, along with detailed engineering, materials supply, civil works, mechanical and electrical assembly, testing, and commissioning. The solar park is scheduled for completion in the first half of 2026.
In addition to the photovoltaic installation, Greening plans to incorporate ecological initiatives such as sheep grazing in the green areas surrounding the park. This effort aims to support the regeneration of the ecosystem, enhance biodiversity, and maintain environmental balance.
Josu Egea, country manager for Greening Germany, emphasized the significance of the project. “This project is a key milestone in our commitment to a more sustainable future, especially in a priority market such as Germany, where we continue to expand our international presence,” Egea said. “By collaborating with Uniper on the transformation of the Wilhelmshaven ash landfill into a renewable generation hub, we are not only boosting the supply of green energy but also promoting green restoration.”
Uniper Renewables’ CEO Jörg Lennertz highlighted the project’s importance to the region and the company’s long-term sustainability goals. “By taking advantage of the site of the ash dump at the Wilhelmshaven power plant, we are transforming a disused industrial area into a high-value renewable energy source,” Lennertz said. “This project underlines Uniper’s commitment to Wilhelmshaven and to the sustainable use of existing infrastructures to ensure a secure energy supply in the future.”
The Voslapper Groden Photovoltaic Park, alongside other planned projects like an electrolysis plant, a hydrogen import terminal, and a visitor center, is expected to play a key role in Uniper’s regional strategy.
