Uniper Builds New 17 Megawatt Peak (MWp) Solar Park On Ash Landfill At Former Wilhelmshaven Power Plant

• Uniper builds a 17 MWp solar park with over 28,500 solar modules on ash landfil
• The 17,000 megawatt-hours (MWh) annual generation of renewable electricity can supply around 4,500 households^[1]

Uniper starts construction of its 17 MWp solar park on the ash landfill of the former Wilhelmshaven coal-fired power plant. This facility will generate approximately 17,000 MWh of renewable electricity annually and would be able to power up to 4,500 households.

Spanning an area of about 14 hectares, the solar park will accommodate over 28,500 solar modules, which will be securely mounted using specialized anchoring systems designed for the landfill site. The project is being developed in close coordination with the City of Wilhelmshaven.

By utilizing the ash landfill site of the former Wilhelmshaven coal-fired power plant, we are transforming unused industrial land into a valuable source of renewable energy. The project highlights Uniper's commitment to Wilhelmshaven and the sustainable use of existing infrastructure to ensure a secure energy supply for the future. The PV Park Voslapper Groden, together with the planned electrolysis plant, the hydrogen import terminal, and the visitor center, forms an important cornerstone of our regional project portfolio.

The site is already fenced and equipped with landscaping measures. Sheep will continue to be grazing the green areas. This grazing supports renaturation, promotes biodiversity, and contributes to ecological balance, while the PV system provides renewable energy.

The construction will be carried out together with Greening Germany, a subsidiary of the international company Greening, specialized in the development and execution of photovoltaic, wind, biogas and BESS energy storage projects. Commissioning is expected in the first half of 2026.

Uniper aims to expanding its renewable portfolio across Europe, with a current focus on Germany, France, the UK, Italy, Sweden, Hungary, and Poland. Next to Wilhelmshaven, Uniper started construction of several solar parks in the United Kingdom and Hungary. The goal is to develop up to 10 gigawatts of capacity ready-to-build by 2030.
