Vattenfall opened its first wind and solar hybrid park in Germany on October 30, 2026. The Hommerdingen-Biesdorf plant in the southern Eifel region combines four wind turbines rated at 17 megawatts (MW) with more than 12,000 solar modules rated at 7.6 MWp, and the two share one grid connection.
Michael Ebling, Minister for Economic Affairs, Tourism, Energy and Climate of Rhineland-Palatinate, attended the opening.
One connection for two power plants
The wind farm sits on the municipal land of Hommerdingen and the solar park on that of Biesdorf. Both belong to the Verbandsgemeinde Südeifel, near the Luxembourg border. Vattenfall connects them to the distribution network of regional operator Westnetz through a single point. The solar park is treated technically like another wind turbine, so the whole facility needs only one grid connection. Westnetz agreed to the concept.
Vattenfall says wind and solar generation follow complementary profiles, which uses the distribution grid more efficiently than either technology alone. It says this improves use of existing grid infrastructure, reduces the risk of grid overload and makes grid connection costs significantly lower than for stand-alone systems.
What officials said
Ebling called the project a flagship for a smart, efficient and economical energy transition. He said it shows wind and solar do not have to compete for scarce grid capacity. For such solutions to spread, he said, Rhineland-Palatinate needs reliable framework conditions, fast permitting processes and intelligent grid connection concepts.
Catrin Jung, Senior Vice President and Head of the Wind Business Unit at Vattenfall, said the company drew on expertise from earlier projects. Vattenfall has run the hybrid concept for several years in the Netherlands and Great Britain, among other places. Jung said Vattenfall plans to add storage to its renewable generation in the future.
